Abstract
OBJECTIVE The purpose of the present study was to evaluate the survival and freedom from reinfection for patients with infected native aortic aneurysms (INAAs) treated with in situ revascularization (ISR), using either open surgical repair (OSR) or endovascular aneurysm repair (EVAR), and to identify the predictors of outcome. METHODS Patients with INAAs who had undergone ISR from January 2005 to December 2020 were included in the present retrospective single-center study. The diagnosis of INAAs required a combination of two or more of the following criteria: (1) clinical presentation, (2) laboratory results, (3) imaging findings, and (4) intraoperative findings. The primary endpoint was 30-day mortality. The secondary endpoints were in-hospital mortality, estimated survival, patency, and freedom from reinfection using the Kaplan-Meier method. The predictive factors for adverse outcomes were evaluated using the Mann-Whitney U test or the Fisher exact test and multivariate regression analysis. RESULTS A total of 65 patients (53 men [81.5%]; median age, 69.0 years; interquartile range, 61.5-75.0 years) were included, 31 (47.7%) were immunocompromised, 60 were symptomatic (92.3%), and 32 (49.2%) had presented with rupture, including 3 aortocaval fistulas (4.6%) and 12 aortoenteric fistulas (18.5%). The most common location was infrarenal (n = 39; 60.0%). Of the 65 patients, 55 (84.6%) had undergone primary OSR with ISR, 3 (4.6%) had required EVAR as a bridge to OSR, and 8 (12.3%) had undergone EVAR as definitive treatment. The approach was a midline laparotomy for 44 patients (67.7%), mostly followed by reconstruction and aortic-aortic bypass (n = 28; 40.6%) and the use of a silver and triclosan Dacron graft (n = 30; 43.5%). Causative organisms were identified in 55 patients (84.6%). The 30-day and in-hospital mortality rates were 6.2% (n = 4) and 10.8% (n = 7). The median follow-up was 33.5 months (interquartile range, 13.6-62.3 months). The estimated 1- and 5-year survival rates were 79.7% (95% confidence interval [CI], 67.6%-87.7%) and 67.4% (95% CI, 51.2%-79.3%). The corresponding freedom from reinfection rates were 92.5% (95% CI, 81.1%-97.1%) and 79.4% (95% CI, 59.1%-90.3%). On multivariate analysis, in-hospital mortality increased with uncontrolled sepsis (P < .0001), rapidly expanding aneurysms (P = .008), and fusiform aneurysms (P = .03). The incidence of reinfection increased with longer operating times (P = .009). CONCLUSIONS The selective use of ISR and OSR combined with targeted antimicrobial therapy functioned reasonably well in the treatment of INAAs, although larger, prospective, multicenter studies with appropriately powered comparative cohorts are necessary to confirm our findings and to determine the best vascular substitute and precise role of EVAR as a bridge to OSR or definitive treatment.

Abstract
OBJECTIVES The aim of this study is to assess any relation between spondylitis and aortic aneurysmal disease by reviewing the current literature. METHODS A systematic search was undertaken using MEDLINE, EMBASE and CENTRAL databases till May 2019, for articles reporting on patients suffering from spondylitis and aortic aneurysm. RESULTS The most involved aortic segment was infrarenal aorta (56.9%). The lumbar vertebrae were more frequently affected (79.7%). Commonest symptoms were back pain (79.1%), fever (33.7%) and lower limb pain (29.1%). 55.8% of cases were diagnosed using computed tomography. The pathology was attributed to infectious causes in 25.1% of cases. 53.4% of patients were treated only for the aneurysm, 27.9% for both pathologies, while two patients solely for the vertebral disease. Endovascular aneurysm repair was chosen in 12.8% of cases. The 30-day mortality was 8.1% (7/86); mostly from vascular complications. CONCLUSIONS A synchronous spondylitis and aortic aneurysm may share common etiopathology, when an infectious or inflammatory cause is presented. The lumbar vertebrae are more frequently affected. Low quality data do not allow safe conclusion to suggest the best treatment option.

Abstract
BACKGROUND Primary infected aneurysms of the abdominal aorta and iliac arteries are potentially life-threatening. However, because of the rarity of the disease, its pathogenesis and optimal treatment strategy remain poorly defined. METHODS A nationwide retrospective cohort study investigated patients who underwent surgical treatment for a primary infected abdominal aortic and/or common iliac artery (CIA) aneurysm between 2011 and 2017 using a Japanese clinical registry. The study evaluated the relationships between preoperative factors and postoperative outcomes including 90-day and 3-year mortality, and persistent or recurrent aneurysm-related infection. Propensity score matching was used to compare survival between patients who underwent in situ prosthetic grafting and those who had endovascular aneurysm repair (EVAR). RESULTS Some 862 patients were included in the analysis. Preceding infection was identified in 30.2 per cent of the patients. The median duration of postoperative follow-up was 639 days. Cumulative overall survival rates at 30 days, 90 days, 1 year, 3 years and 5 years were 94.0, 89.7, 82.6, 74.9 and 68.5 per cent respectively. Age, preoperative shock and hypoalbuminaemia were independently associated with short-term and late mortality. Compared with open repair, EVAR was more closely associated with persistent or recurrent aneurysm-related infection (odds ratio 2.76, 95 per cent c.i. 1.67 to 4.58; P < 0.001). Propensity score-matched analyses demonstrated no significant differences between EVAR and in situ graft replacement in terms of 3-year all-cause and aorta-related mortality rates (P = 0.093 and P =0.472 respectively). CONCLUSION In patients undergoing surgical intervention for primary infected abdominal aortic and CIA aneursyms, postoperative survival rates were encouraging. Eradication of infection following EVAR appeared less likely than with open repair, but survival rates were similar in matched patients between EVAR and in situ graft replacement.

Abstract
OBJECTIVE To evaluate the short and long-term results of in situ prosthetic graft treatment using rifampicin-soaked silver polyester graft in patients with aortic infection. MATERIAL AND METHOD All the patients surgically managed in our center for an aortic infection were retrospectively analyzed. The primary endpoint was the intra-hospital mortality, secondary outcomes were limb salvage, persistent or recurrent infection, prosthetic graft patency, and long-term survival. RESULTS From January 2004 to December 2015, 18 consecutive patients (12 men and 6 women) were operated on for aortic infection. Six mycotic aneurysms and 12 prosthetic infections, including 8 para-entero-prosthetic fistulas, were treated. In 5 cases, surgery was performed in emergency. During the early postoperative period, we performed one major amputation and two aortic infections were persistent. Intra-hospital mortality was 27.7%. The median follow-up among the 13 surviving patients was 26 months. During follow-up, none of the 13 patients presented reinfection or bypass thrombosis. CONCLUSION This series shows that in situ revascularization with rifampicin-soaked silver polyester graft for aortic infection have results in agreement with the literature in terms of intra-hospital mortality with a low reinfection rate.

Abstract
BACKGROUND Infected false aneurysms (IFA) caused by intravenous drug abuse are uncommon but challenging lesions. The best approach for the surgical management of this condition is still unknown. The aim is to present a single-center 14-year experience in the IFA treatment in intravenous drug abusers, thus providing additional data regarding the treatment options and outcome in these patients. METHODS A retrospective analysis of 32 consecutive patients with vascular injuries secondary to intravenous drug abuse, during the period from January 2004 to April 2018, was performed. Data of interest were extracted from patients' medical history records, anesthesia charts, and database implemented in daily practice, or were obtained by personal contact. The diagnosis was set based on history, physical examination and/or color Doppler sonography, multidetector computed tomographic angiography, and digital subtraction angiography. The outcome included graft patency, limb amputation, and mortality. RESULTS During study period, 32 heroin abusers, predominantly males (81%), were surgically treated due to vascular injuries, with mean age of 35.2 years. The vast majority of patients have had an injury of the lower extremity blood vessels (84.3%) and the common femoral artery was the most common site of injury (59.4%). Three-quarters of patients underwent resection of the false aneurysm and ligation of the artery without reconstruction of the blood vessel. In 7 cases (21.9%), arterial reconstruction was performed with overall failure rate of 42.86%. The overall mortality rate was 6.25% and the rate of extremity salvage was 96.7%. CONCLUSIONS The best treatment option is yet to be found, but based on the results of the present study, ligation of affected artery without revascularization seems to be an efficient, safe, and optimal treatment method, with minor risk of the extremity loss.

Abstract
OBJECTIVE Since chronic Q fever often develops insidiously, and symptoms are not always recognized at an early stage, complications are often present at the time of diagnosis. We describe complications associated with vascular chronic Q fever as found in the largest cohort of chronic Q fever patients so far. METHODS Patients with proven or probable chronic Q fever with a focus of infection in an aortic aneurysm or vascular graft were included in this study, using the Dutch national chronic Q fever database. RESULTS A total of 122 patients were diagnosed with vascular chronic Q fever between April 2008 and June 2012. The infection affected a vascular graft in 62 patients (50.8%) and an aneurysm in 53 patients (43.7%). Seven patients (5.7%) had a different vascular focus. Thirty-six patients (29.5%) presented with acute complications, and 35 of these patients (97.2%) underwent surgery. Following diagnosis and start of antibiotic treatment, 26 patients (21.3%) presented with a variety of complications requiring surgical treatment during a mean follow-up of 14.1 ± 9.1 months. The overall mortality rate was 23.7%. Among these patients, mortality was associated with chronic Q fever in 18 patients (62.1%). CONCLUSIONS The management of vascular infections with C. burnetii tends to be complicated. Diagnosis is often difficult due to asymptomatic presentation. Patients undergo challenging surgical corrections and long-term antibiotic treatment. Complication rates and mortality are high in this patient cohort.

Abstract
We reviewed all papers most recently reported in the literature (January-December 2008) with regard to infected arterial aneurysms (IAAs) affecting the aorta. Most of the recently reported knowledge is limited to case reports and small series of aortic mycotic aneurysms. Most patients are elderly men and have comorbidities at presentation. Aneurysms were most commonly associated to Salmonella and Staphylococcus. However, several cases of aortic IAAs caused by atypical pathogens were also reported, likely due to an increase in immunosuppressive illnesses, increased life expectancy, improved diagnostic methods, and increasing medical awareness. Open surgical therapy of IAAs remains the gold standard. Some have reported successful outcomes with endovascular methodologies for patients medically compromised or for particular challenging clinical or anatomical scenarios. However, at this time, conclusive evidence is lacking and it should be in general considered a bridge to open repair. The latter should be planned at the earliest possible, when medically permissible.

Abstract
Pathology of infected aortic aneurysm and its clinical correlation have rarely been reported. Between 1995 and 2005, 48 patients with infected aortic aneurysm underwent in situ graft replacement. Twenty-five patients had a suprarenal and 23 patients had an infrarenal infection. The most common responsible pathogen was nontyphoid Salmonella in 32 patients (67%). During operation, gross pus was present in 26 patients (54%). On pathological examination, aortic atherosclerosis was present in all cases, acute suppurative inflammation was present in 31 patients (65%), and bacterial clumps were present in five patients (10%). Positive culture of the aneurysm wall was present in 14 patients (29%). There were 10 patients with prosthetic graft infection (21%) and 12 patients with aneurysm-related death (25%). Although statistically insignificant, local purulent infection with positive culture of the aneurysm wall, gross pus during operation, or acute suppurative inflammation on pathology tended to be associated with high risk of prosthetic graft infection and aneurysm-related death. In conclusion, infected aortic aneurysm occurred in patients with aortic atherosclerosis. On pathology, acute suppurative inflammation was present in the majority of cases but bacterial clumps were not commonly present. Local purulent infection tended to be associated with high risk of prosthetic graft infection and aneurysm-related death.

Abstract
BACKGROUND Psoas abscess is an uncommon disease, and its presenting features are usually nonspecific. Infected aortic aneurysms could be complicated by psoas abscess. METHODS A retrospective chart review was conducted to examine the incidence, clinical presentations, microbiology, and outcomes of psoas abscess in patients with an infected aortic aneurysm. RESULTS Between 1996 and 2007, 40 patients (32 men) with an infected infrarenal aortic aneurysm were treated in our hospital. Their median age was 71 years (range, 38 to 88 years). In 38 patients a blood or tissue culture had a positive result. The most common responsible pathogen was Salmonella spp in 29 patients (76%), followed by Staphylococcus aureus in 3 (8%), Escherichia coli in 2 (5%), Klebsiella pneumoniae in 3 (8%), and Mycobacterium tuberculosis in 1 (3%). One patient underwent endovascular repair but died. In-situ graft replacement was done in 32 patients. Persistent or recurrent infection occurred in seven (22%) of 32 operated on patients. The mortality rate was 86%, and the overall aneurysm-related mortality rate of in situ graft replacement was 22% (7/32). In eight (20%) of the 40 patients, aortic infection was complicated by psoas abscess. Infection complicated by psoas abscess was present in seven of 32 operated patients. It was associated with higher incidence of emergency operation, hospital mortality, prosthetic graft infection, and aneurysm-related mortality than infection without abscess. CONCLUSION Psoas abscess was common in patients with infected infrarenal aortic aneurysm. Salmonella spp was the most common pathogen. Psoas abscess was associated with a high mortality rate, emergency operation, and persistent infection.

Abstract
BACKGROUND Intracranial infectious aneurysms (IA) are infrequent, but can be fatal. OBJECTIVES To compare the clinical profile of IAs associated with intravascular/systemic infection like infective endocarditis with that associated with local infections like meningitis, orbital cellulitis and cavernous sinus thrombosis. METHODS We analysed all cases of IA, treated in this Institute from 1976 to 2003, in order to identify prognostic factors. RESULTS There were 25 persons (mean age 24.8+/-17.3 years, males 17) with 29 IA (carotid circulation 19, vertebrobasilar circulation 10). Headache (83%) and fever (67%) were the most common presenting symptoms. In contrast to noninfectious aneurysms, intracerebral haemorrhage (60%) and focal signs were more common than subarachnoid haemorrhage (7%) with IA. Sources of infection were cardiac (10), meningitis (12), orbital cellulitis (2) or uncertain (1). Infective agents included bacteria (18), fungi (4), and tubercle bacilli (3). Fifteen IA were distal and 14 were proximal. IAs associated with meningitis were proximal (75%) while those associated with cardiac diseases preferentially involved carotid territory and were distal (p=0.013). The overall mortality was 32%. Survivors were younger than those who expired (p=0.015). Of the sixteen patients treated medically, seven recovered (44%), others (56%) had treatment failure (three died and six required surgery later). Another five patients underwent early surgery (one died). Mortality of IA was significantly higher with meningitis, fungal aetiology and vertebrobasilar location. CONCLUSIONS IAs associated with local infections like meningitis had different clinical profile as compared to IAs associated with intravascular/systemic infections like infective endocarditis.

Abstract
BACKGROUND Nontyphoid Salmonella (NTS) isolates lead to not only self-limited, acute gastrointestinal infections, but also bacteraemia with or without extraintestinal focal infections (EFIs). The risk factors associated with EFIs in adults with NTS bacteraemia were not clearly elucidated. METHODS In a medical center in southern Taiwan, patients aged > or = 18 years with NTS bacteraemia between January 1999 and June 2005 were included for analysis. RESULTS Of 129 patients, 51 (39.5%) were complicated with EFIs. The most common EFI was mycotic aneurysm, followed by pleuropulmonary infections and spinal osteomyelitis. Compared to patients with primary bacteraemia, those with EFIs had higher leucocyte counts (P = 0.004) and higher serum levels of C-reactive protein (P < 0.0001). The development of EFIs was associated with a higher mortality, more severe septic manifestations, longer hospital stays and duration of antimicrobial therapy. Univariate analysis revealed that diabetes mellitus (P = 0.02), hypertension (P = 0.02) and chronic lung disease (P = 0.006) were significantly associated with EFIs. However, patients with malignancy (P = 0.01) and immunosuppressive therapy (P = 0.03) were less likely to develop EFIs. On the basis of multivariate analysis, an independent factor for the occurrence of EFIs was age [adjusted odds ratio (aOR) 1.05; 95% confidence interval (CI) 1.02-1.07; P < 0.0001], whilst malignancy was negatively associated with EFIs (aOR 0.16; 95% CI 0.14-0.78; P = 0.01). CONCLUSION Amongst patients with NTS bacteraemia, EFIs often occurred in the aged, and were associated with a higher mortality and morbidity. Recognition of specific host factors is essential for identification of EFIs which often demand early surgical interventions and prolonged antimicrobial therapy.

Abstract
The natural history of infected aneurysms or arterial infections is characterized by rapid expansion leading to rupture, pseudoaneurysm formation, and sepsis. Treatment options include in situ grafting either with prosthetic or autogenous grafts or with cryopreserved allografts (CPAs), resection of the aneurysm with remote bypass grafting, and ligation. The purpose of this study was to review our recent experience with these infections and to present long-term follow-up with in situ CPAs. From January 2000 through June 2005, we treated nine patients with infected aneurysms and one patient with an infection without aneurysm formation. The infection involved the infrarenal abdominal aorta in six patients and the femoral artery in three patients. One patient had an infected splenic artery aneurysm. Aortic rupture occurred in five of the six patients with infected aortas. Two of the three patients with infected femoral aneurysms presented with recurrent hemorrhage. Of the six patients with aortic infections, five were treated with in situ CPAs. One patient was treated with aortic resection and axillofemoral grafting. Two patients with femoral aneurysms were treated with in situ CPAs, and the third patient underwent aneurysm resection and prosthetic grafting through the obturator foramen. The patient with the splenic aneurysm underwent combined valve replacement, aneurysm resection, and splenectomy. Three of the six patients with aortic infections died postoperatively, all of whom were septic at presentation. The cause of death in these three patients was multiple organ failure in two and overwhelming sepsis in one. The three survivors are alive and well with up to 5-year follow-up. The three patients with infected femoral aneurysms are alive and well with follow-up extending to 44 months. The patient with the splenic aneurysm is doing well. No recurrent infections have been noted among the survivors. The CPAs have remained structurally intact in all. The mortality rate among patients with abdominal aortic infections remains high and is likely related to their preoperative septic state. In situ grafting with CPAs appears to be a reasonable treatment option for arterial infections. CPAs appear to maintain their structural integrity and to be resistant to recurrent infection.

Abstract
BACKGROUND Salmonella infection of the aorta and adjacent arteries is rare, but life-threatening. There is an increasing number of infections caused by antimicrobial drug resistant Salmonella. This study sought to assess the association between antimicrobial drug resistance and clinical outcomes of patients with Salmonella-infected aortic aneurysm. METHODS Data were collected by retrospective chart review. Between October 1995 and October 2004, 34 patients with Salmonella-infected aortic aneurysm were included. Aneurysm-related deaths were defined as hospital deaths and late deaths due to prosthetic graft infection. Analysis was performed using the chi2 test, Fisher's exact test, and Mann-Whitney test. RESULTS Nineteen patients had a suprarenal and 15 patients had an infrarenal aortic infection. The most common responsible pathogen was group C Salmonella (47%). Ciprofloxacin-resistant Salmonella infection occurred since March 2001 and the rate increased from 0 per 15 in the years before March 2001 to 5 per 19 in the years after March 2001 (p = 0.005 by Fisher's exact test). Among the 26 patients who had combined medical and surgical therapy, 4 died in the hospital and 4 died of late prosthetic graft infection 3 to 6 months after operation, whereas 4 of the 8 who had medical therapy alone died of aneurysm rupture during hospitalization. The actuarial survival rates by the Kaplan-Meier method were 64% at 6 months, 61% at 1 year, and 56% at 5 years. The risk factors for aneurysm-related death were old age (78.5 +/- 9.7 years vs 63.5 +/- 11.4 years; p < 0.001) and ciprofloxacin-resistant Salmonella infection (4 of 5 vs 8 of 29; p = 0.042). CONCLUSIONS There was an increased mortality associated with ciprofloxacin resistance in infected aortic aneurysms with Salmonella. With an increasing incidence of ciprofloxacin resistant Salmonella, third generation cephalosporin is the antibiotic of choice for Salmonella-infected aneurysm.

Abstract
BACKGROUND Thoracic aorta false aneurysms (TAFA) are a surgical challenge. The best technical approach remains uncertain. METHODS Between 1981 and 2004, 57 patients underwent operation for TAFA (mean age 57 +/- 18 years; 43 [75%] were male). Symptoms included dyspnea 25 (44%), chest pain 22 (39%), and fever 18 (32%). Twelve (21%) were asymptomatic. Thirty-seven (65%) had undergone previous operation with a mean interval between operations of 80 +/- 90 months. Fifteen (26%) had a mycotic etiology. The TAFA involved the aortic root in 10 (18%), ascending aorta in 28 (49%), arch in 6 (11%), and descending aorta in 13 (32%). Twenty-one (37%) required femorofemoral cannulation and 28 (49%), circulatory arrest. Surgical techniques included graft replacement in 27 (47%), composite root in 10 (18%), patch repair in 10 (18%), and direct suture in 10 (18%). RESULTS Operative mortality was 7% (4 patients). Four of 32 (13%) had massive hemorrhage during redo sternotomy, and all of these had planned extramediastinal cannulation (all survived). Follow-up was 100% for 349 patient-years. Actuarial survival was 77% +/- 6%, 63% +/- 8%, and freedom from recurrent TAFA was 87% +/- 5% and 83% +/- 7%, at 5 and 10 years, respectively. Univariate analysis identified TAFA greater than 55 mm, urgent operation, and NewYork Heart Association functional class III or IV as predictors of hemorrhage during redo sternotomy. Obesity and ejection fraction of 35% or less were predictors of operative death. CONCLUSIONS Thoracic aorta false aneurysm symptoms may be minimal, and consequently a high degree of suspicion plus serial imaging is warranted. Extramediastinal cannulation, deep hypothermia, and circulatory arrest are required for large mediastinal TAFA. Despite serious risks, TAFA correction is possible with good long-term results.

Abstract
PURPOSE To evaluate the feasibility and effectiveness of endovascular stent-graft repair of infected aortic and arterial aneurysms. METHODS Eight patients (5 men; mean age 56.6 years, range 30-85) with infected saccular aneurysms in the brachiocephalic artery (n=1), proximal descending thoracic aorta (n=1), infrarenal abdominal aorta (n=3), common iliac artery (n=1), and common femoral artery (n=2) were treated with stent-graft placement and intravenous antibiotic treatment for at least 6 weeks followed by case-specific administration of oral suppressive antibiotics. All patients were considered to be in the high-surgical-risk group. RESULTS Exclusion of the infected aneurysm was successful in all patients. However, 2 patients died within 30 days of uncontrolled sepsis, and 1 patient died at 6 months after rupture of a persistently infected aneurysm (37% mortality rate). Over a follow-up that ranged to 8 years, the 5 survivors showed complete resolution of the infected aneurysms; no stent-graft infection was observed during follow-up. CONCLUSION The acceptable technical and clinical success of endovascular aneurysm repair makes this a promising treatment for infected aortic and arterial aneurysms. However, it is crucial that the infection is treated adequately prior to stent-graft placement.

Abstract
Nine cases of mycotic thoracic aortic aneurysm were treated surgically between July 1995 and March 2003. The aneurysms were located in the ascending aorta in 1 patient, the descending thoracic aorta in 5, and the thoracoabdominal aorta in 3. Preoperatively, 3 patients were in shock due to rupture of the aneurysm. All patients underwent aneurysmectomy and in-situ graft placement. In 5 patients, the graft was covered with a pedicled omental flap to prevent postoperative graft infection. There were 2 hospital deaths: one patient died of multi-organ failure, and the other died from intrathoracic bleeding. After discharge, one patient died from intrathoracic bleeding 3 months after surgery. These 3 patients had not received omental wrapping. Postoperative graft infection did not occur in the 6 surviving patients during a mean follow-up period of 4.0 +/- 3.1 years. It was concluded that covering the prosthetic graft with a pedicled omental flap may help prevent postoperative graft infection and improve the surgical results.

Abstract
BACKGROUND Mycotic aneurysm remains a lethal pathologic entity, especially when rupture occurs. It may result from primary aortitis, be induced by septic emboli, or be secondary to an adjacent infection, such as pancreatitis or a psoas muscle abscess. Surgical intervention is the only way to treat such disease. Even when successful repair is achieved by insertion of an interposition in situ graft or by performance of an extra-anatomic bypass, the prognosis is poor. The aim of this study was to present our experience of managing mycotic aortic aneurysms during the past 10 years. METHODS From January 1994 to June 2004, a total of 734 patients with aortic aneurysms underwent surgical repair at our institution. Among these cases, 17 (2.3%) were shown to be mycotic aneurysms of the ascending aorta (n = 1), aortic arch (2), thoracic and thoracoabdominal aorta (3), or abdominal aorta (11); 14 patients (mean age, 58.8 years) were male. Preoperative imaging studies were performed in all patients. Mycotic aortic aneurysms were suspected in 12 of the 17 patients (70.6%) preoperatively, and 4 of these 12 patients were found to have ruptures on imaging. At the time of surgery, 9 of the 17 aneurysms (52.9%) were ruptured. Fifteen patients had an interposition graft inserted after meticulous debridement, 1 underwent an aorto-aortic bypass, and 1 underwent an extra-anatomic (axillo-femoral) bypass. An omentum patch was applied to wrap the graft in 8 of 11 mycotic aortic aneurysms of the abdominal aorta. The most common pathogens were Salmonella spp. (n = 7) and Staphylococcus spp. (4). All patients received antibiotic therapy, according to the culture report, for about 4-6 weeks postoperatively. RESULTS In-hospital mortality was 11.8% (n = 2). Another patient died from massive upper gastrointestinal bleeding 6 months after operation because of complications involving an aorto-duodenal fistula, and another died from stomach cancer 6 years after surgery. Long-term follow-up (mean, 37 months; range, 3-111 months) revealed that, at the time of writing, the remaining 13 patients were alive and well, without any recurrence of aneurysm. CONCLUSION Mycotic aneurysm of the aorta is a life-threatening disease, especially when rupture occurs. The high mortality rate is due not only to the high rupture rate, but also to sepsis. When mycotic aortic aneurysm is diagnosed, early surgical intervention is mandatory.

Abstract
PURPOSE To report the benefit of endoluminal repair of mycotic aortic aneurysms and highlight the need for a registry. METHODS Nine patients (five female) were identified over 5 years (1998-2003) as having presumed mycotic aortic aneurysms (12 in total) suitable for endoluminal grafting. A total of nine thoracic and three abdominal were grafted and followed up for a median of 36 months. RESULTS Six of the aneurysms have resolved and one was converted to an open repair. There was one early death from rupture of a second undiagnosed aneurysm and two late deaths from rupture due to persistent inflammation. Long-term antibiotics have not been mandatory to ensure survival. CONCLUSIONS Mycotic aortic aneurysms of the thoracic and abdominal aorta do benefit from endoluminal repair, particularly when arising in previously normal aortic tissue. Endoluminal grafting also has a role in the palliation of secondarily infected aortas and so to prove its efficacy in the treatment of all these rare cases a registry is required.

Abstract
PURPOSE Infected aortic aneurysms are difficult to treat, and are associated with significant mortality. Hospital survival is poor in patients with severe aortic infection, Salmonella species infection, Staphylococcus aureus infection, aneurysm rupture, and suprarenal aneurysm location. We reviewed the clinical outcome in 46 patients with primary infected aortic aneurysms and identified clinical variables associated with prognosis. METHODS Data were collected by means of retrospective chart review. Univariate and multivariate logistic regression models were used for risk factor analysis. RESULTS Between August 1995 and March 2003, 48 patients with primary infected aortic aneurysms were treated at our hospitals. Two patients with negative culture results were excluded. Of the remaining 46 patients, 35 patients had aortic aneurysms infected with Salmonella species and 11 patients had aortic aneurysms infected with microorganisms other than Salmonella species. There were 20 suprarenal infections and 26 infrarenal infections. Surgical debridement and in situ graft replacement were performed in 35 patients, with an early mortality rate of 11%. The incidence of late prosthetic graft infection was 10%. The 90-day mortality rate in patients operated on was 0% for elective operation and 36% for nonelective operation (P =.006, Fisher exact test). Independent predictors of aneurysm-related death were advanced age, non-Salmonella infection, and no operation. CONCLUSION With timely surgical intervention and prolonged antibiotic treatment, in situ graft replacement provides an excellent outcome in patients with primary infected aortic aneurysms and elective operation. Mortality is still high in patients undergoing urgent operation. Advanced age, non-Salmonella infection, and no operation are major determinants of mortality.

Abstract
OBJECTIVE To review our experience of using cryopreserved allografts for in situ reconstruction in the presence of infection involving the aorta, iliac or femoral arteries. DESIGN Retrospective clinical study. METHODS From 3/2000 to 8/2003 all patients with mycotic aneurysms or secondary infection following earlier prosthetic replacement were treated with cryopreserved human allografts. Forty-two patients, 39 (93%) with a prosthetic graft infection and 3 (7%) with a mycotic aneurysm of the abdominal aorta were treated. Six (14%) had aorto-enteric fistulas, 5 (12%) had ruptured aneurysms, and 2 also had vertebral destruction. The median follow-up time was 20 months (range 1-42 months). RESULTS Thirty-day mortality was 14%. Three patients died due to multi-organ failure, two patients died from hypovolaemic shock due to allograft rupture and one from rupture of the native aorta. The overall mortality was 24% (four additional patients). Graft patency was 100% at 30 days and 97% at follow up in the survivors. The mean actuarial survival time was 32 months (95% CI=27-37 months). CONCLUSIONS Cryopreserved allografts for the in situ reconstruction of infected arteries or grafts have acceptable intermediate results.

Abstract
BACKGROUND Mortality in patients with infected aortic aneurysms remains high. A number of patient- and infection-specific risk factors for death have been proposed, but none is consistently predictive of poor outcomes. The purpose of this study was to examine the possible contribution of infection-related risk factors and the systemic inflammatory response syndrome (SIRS) to outcomes of patients with infected aortic aneurysms. STUDY DESIGN Ten patients with infected aortic aneurysms presenting to our institution over a recent 6-year period were studied. Collected data included aneurysm location, culture results, preoperative indicators of SIRS, operative details, and outcomes. RESULTS Common presenting symptoms included abdominal or back pain and fevers. Aneurysms involved the thoracoabdominal aorta in four patients, the suprarenal aorta in one, the juxtarenal aorta in one, and the infrarenal aorta in four. Seven patients met criteria for SIRS. Repairs included in situ replacement of the infected aneurysm using rifampin-soaked, gel-impregnated Dacron in four patients with thoracoabdominal aneurysms and using autogenous superficial femoral-popliteal vein in five patients with infrarenal aneurysms. Four patients died of sepsis, and six patients survived to discharge after a mean of 23 +/- 12 days in the hospital, followed by extensive rehabilitation. The combination of SIRS and suprarenal extension was present in all four patients who died. CONCLUSIONS Although rare, infected aortic aneurysms are associated with marked morbidity and mortality. Sepsis is the leading cause of death. A combination of host- and infection-specific variables may be more predictive of outcomes than any single risk factor. Prolonged hospitalization and extended rehabilitation are frequently required in survivors, but longterm outlook is good after successful treatment.

Abstract
OBJECTIVE The purpose of this study was to better define the management of intracranial infectious aneurysms. METHODS We present a retrospective review of the management of 16 patients with intracranial infectious aneurysms. The mean follow-up period was 86 months. RESULTS None of the patients had a rehemorrhage during antibiotic treatment. The mortality and long-term outcome from ruptured intracranial infectious aneurysms may be better than previously thought. There was no significant difference in long-term outcome between patients with single or multiple infectious aneurysms or between patients who underwent surgical resection and those who were treated only with antibiotics. CONCLUSION Operative treatment should be pursued for patients with ruptured infectious aneurysms. Patients with unruptured intracranial infectious aneurysms should be observed during antibiotic therapy and followed up with cerebral angiography. Surgical resection should be considered if the aneurysm enlarges and the patient's general medical condition allows general anesthesia to be tolerated.

Abstract
OBJECTIVE Aortic reconstructions for primary graft infection (PGI), mycotic aneurysm (MA), and aortic graft-enteric erosion (AEE) bear high morbidity and mortality rates, and current treatment options are not ideal. Cryopreserved grafts have been implanted successfully in infected fields and may be suitable for abdominal aortic reconstructions. Registry data from several institutions were compiled to examine results of cryopreserved aortic allograft (CAA) placement. METHODS The experience of 31 institutions was reviewed for CAAs inserted from March 4, 1999, to August 23, 2001. Indications for CAA, organisms, mortality, and complications were identified. RESULTS Fifty-six patients, 43 men and 13 women, with a mean age of 66 years (range, 44 to 90 years) had in situ aortic replacement with CAA. Indications for CAA placement were PGI in 43 patients (77%), MA in seven (14%), AEE in four (7%), and aortic reconstruction with concomitant bowel resection in two (4%). Infectious organisms were identified in 33 patients (59%); the most frequent organism was Staphylococcus aureus in 17 (52%). Thirty-one patients (55%) needed an additional cryopreserved segment for reconstruction. The mean follow-up period was 5.3 months (range, 1 to 22 months). One patient died in the operating room, and the 30-day surgical mortality rate was 13% (7/56). Seven additional patients died during the follow-up period, yielding an overall mortality rate of 25% (14 patients). Two patients (4%) had graft-related mortality as the result of hemorrhage from the CAA and persistent infection. Graft-related complications included persistent infection with perianastomotic hemorrhage in five patients (9%), graft limb occlusion in five (9%), and pseudoaneurysm in one (2%). Three patients (5%) needed amputation. CONCLUSION In situ aortic reconstruction with CAA in infected fields carries a high mortality rate, but most deaths are not the result of allograft failure. However, CAA infection and lethal hemorrhage caused by graft rupture occurs and is concerning. Early reinfection was not reported. Late graft-related complications, such as reinfection, thrombosis, or aneurysmal changes, are unknown. Preliminary data from this registry fail to justify the preferential use of CAA for PGI, MA, or AEE. A multicenter, randomized study is needed to compare results with established techniques.

Abstract
PURPOSE In situ repair with cryopreserved vascular allografts improves the results in the surgical treatment of aortic infection. This study evaluated the technical pitfalls with the use of allografts that influence early and midterm mortality. METHODS Between 1990 and 1999, 49 patients, 21 (43%) with a mycotic aneurysm and 28 (57%) with a prosthetic graft infection of the thoracic and abdominal aorta including pelvic and groin vessels, underwent in situ repair with cryopreserved arterial allografts. Seventeen patients (35%) had aortobronchial, aortoesophageal, or aortoenteric fistulas. RESULTS Allograft-related technical problems occurred in eight patients (16%) in this series, and they included: intraoperative rupture caused by allograft friability; allograftenteric fistula from ligated allograft side branches rupturing 8, 18, and 48 months after implantation; anastomotic failure caused by inappropriate mechanical stress; anastomotic stricture after partial replacement of infected prosthetic grafts; allograft failure caused by inappropriate wound drainage; and recurrence of infection after inappropriate duration of antifungal treatment. Seven of the eight technical problems (87%) occurred in the first 10 patients (80%) in this series. There was one technical failure in the remaining 39 patients (2.6%; P =.0002) because of various technical adaptations, such as critical selection of allografts, use of allograft strips supporting large anastomoses, sealing with antibiotic-impregnated fibrin glue, and change in technique of allograft side-branch ligature. The 30-day mortality rate was 6% for the whole series; however, it was 2.6% for last 39 patients, with no recurrence of infection or allograft-related late death. CONCLUSIONS In situ repair with cryopreserved arterial allografts achieves excellent early and late results in the treatment of aortic infection. However, distinct allograft-related technical problems had to be overcome to improve the outcome of patients with major vascular infections.

Abstract
OBJECTIVE Infected aortic aneurysms are rare, difficult to treat, and associated with significant morbidity. The purpose of this study was to review the management and results of patients with infected aortic aneurysms and identify clinical variables associated with poor outcome. METHODS The clinical data and early and late outcomes of 43 patients treated for infected aortic aneurysms during a 25-year period (1976-2000) were reviewed. Variables were correlated with risk of aneurysm-related death and vascular complications, defined as organ or limb ischemia, graft infection or occlusion, and anastomotic or recurrent aneurysm. RESULTS Infected aneurysms were infrarenal in only 40% of cases. Seventy percent of patients were immunocompromised hosts. Ninety-three percent had symptoms, and 53% had ruptured aneurysms. Surgical treatment was in situ aortic grafting (35) and extra-anatomic bypass (6). Operative mortality was 21% (9/42). Early vascular complications included ischemic colitis (3), anastomotic disruption (1), peripheral embolism (1), paraplegia (1), and monoparesis (1). Late vascular complications included graft infection (2), recurrent aneurysm (2), limb ischemia (1), and limb occlusion (1). Mean follow-up was 4.3 years. Cumulative survival rates at 1 year and 5 years were 82% and 50%, respectively, significantly lower than survival rates for the general population (96% and 81%) and for the noninfected aortic aneurysm cohort (91% and 69%) at same intervals. Rate of survival free of late graft-related complications was 90% at 1 year and 5 years, similar to that reported for patients who had repair of noninfected abdominal aortic aneurysms (97% and 92%). Variables associated with increased risk of aneurysm-related death included extensive periaortic infection, female sex, Staphylococcus aureus infection, aneurysm rupture, and suprarenal aneurysm location (P <.05). For risk of vascular complications, extensive periaortic infection, female sex, leukocytosis, and hemodynamic instability were positively associated (P <.05). CONCLUSION Infected aortic aneurysms have an aggressive presentation and a complicated early outcome. However, late outcome is surprisingly favorable, with no aneurysm-related deaths and a low graft-related complication rate, similar to standard aneurysm repair. In situ aortic grafting is a safe and durable option in most patients.

Abstract
The surgical outcome of infectious abdominal aortic aneurysms was evaluated based on the preoperative presence or absence of systemic inflammatory response syndrome (SIRS). Nine patients were divided into two groups according to the criteria for SIRS such as body temperature, heart rate, respiratory rate, and white blood cell count. In the group with SIRS, rupture and impending rupture of aneurysms occurred in three of the four patients (75%). All aneurysms were resected with a small part as a remnant; two in situ and two extraanatomic reconstructions were performed. Three patients died after surgery: one after in situ (cerebral infarction) and two after extraanatomic reconstruction (sepsis and multiple organ failure). In the group without SIRS, closed en bloc resection in two patients and resection of the aneurysm with a small part as a remnant in three patients were performed. In situ reconstruction in all patients and omentum wrapping in two patients were performed. One of the five patients died of massive hematemesis 70 days after surgery. The overall mortality rate was 75% in the group with SIRS versus 20% in the group without SIRS. The surgical outcome of infectious abdominal aortic aneurysm depends upon the severity of underlying infection. A possibility exists that SIRS is a useful indicator for predicting the surgical outcome of patients.

Abstract
We report three cases of ruptured mycotic thoracoabdominal aortic aneurysms (TAAAS) and a review of the literature. Escherichia coli and Streptococcus pneumoniae (2 patients) were the responsible organisms. Surgical management consisted of wide debridement of necrotic tissue and in situ repair with a Dacron graft. Antibiotics were administered intravenously in the hospital and continued orally after discharge for at least 6 weeks, until clinical and laboratory parameters were normalized. A review of the literature showed that Gram-negative microorganisms are found in 47% of mycotic TAAAs. A trend toward increased mortality for these organisms, compared with Gram-positive microorganisms, was observed (P =.09). Lifelong antimicrobial therapy is controversial. No difference in survival or recurrence rate was found between series advocating lifelong therapy and those suggesting prolonged (6 weeks to 12 months) therapy (median follow-up period, 18 and 19 months, respectively). In situ repair with synthetic material can be successful if prompt confirmation of infection is obtained, all possibly infected tissue is resected, and antibiotic therapy based on sensitivity data is administered for a prolonged period. A short-term survival rate as high as 82% can be expected with this strategy, but data on long-term survival rates are limited. Polytetrafluoroethylene-expanded grafts, homografts, and antibiotic-bonded grafts may offer advantages over Dacron grafts, but data are insufficient to draw conclusions. Careful long-term follow-up is an important element of the treatment of these patients. We suggest antibiotic treatment until biochemical parameters of inflammation (white cell count, erythrocyte sedimentation rate, or C-reactive protein) return to normal and a computerized tomography scan every 3 months for 1 year, then annually.

Abstract
Infected aneurysms (IA) of neck and limb arteries are uncommon. This report describes the results of a retrospective study undertaken by the University Association for Surgical Research (AURC) to evaluate etiology, bacteriology, location, diagnostic features, and therapeutic methods associated with IA. A total of 58 IA in 52 patients were reviewed. The lesion was located in a lower extremity artery in 47 patients (81%), internal carotid artery in 7 (12%), and upper extremity artery in 4 (6%). Eleven patients had multilocular aneurysm (21%). Symptoms of local infection were observed in 43 patients (82.6%). Rupture or splitting was the presenting manifestation in 13 patients (25%). Primary IA following bacteremia or septicemia without endocarditis was the most common type of IA observed in 34 patients (65.3%). Twelve patients (23%) presented mycotic IA secondary to bacterial endocarditis. In the remaining six patients (11.5%), IA resulted from direct contamination or spreading from a contiguous infection site. Surgical treatment included ligation of the artery without reconstruction in 19 patients and exclusion bypass in 33 patients. The duration of antibiotic treatment ranged from 15 days to 3 months. No recurrence of aneurysm was observed but three patients developed bypass infection. Primary IA was associated with high mortality due to severe septicemia.

Abstract
OBJECTIVE A mycotic aneurysm of the aorta and adjacent arteries is a dreadful condition, threatening life, organs, and limbs. With regard to the aortic segment involved, repair by either in situ replacement or extra-anatomic reconstruction can be quite challenging. Even when surgery has been successful, the prognosis is described as very poor because of the weakened health status of the patient who has developed this type of aneurysm. The aim of our study was to find out whether any progress could be achieved in a single center over a long time period (18 years) through use of surgical techniques and antiseptic adjuncts. MATERIAL AND METHODS From January 1983 to December 1999, a total of 2520 patients with aneurysms of the thoracic and abdominal aorta and iliac arteries underwent surgery for aortic or iliac replacement at our institution. During that period, 33 (1.31%) of these patients (mean age, 64.3 years) were treated for mycotic aneurysms of the lower descending and thoracoabdominal (n = 13), suprarenal (n = 4), and infrarenal (n = 10) aorta and iliac arteries (n = 6). Twenty (61%) of these 33 patients had histories of various septic diseases; in the other 13 (39%), the etiology remained uncertain. Preoperative signs of infection, such as leukocytosis and elevated C-reactive protein, were found in 79% of the patients, and fever was apparent in 48%; 76% of the patients complained of pain. At the time of surgery, eight (24%) mycotic aneurysms were already ruptured, and 20 (61%) had penetrated into the periaortic tissues, forming a contained rupture. Five (15%) aneurysms were completely intact. The predominant microorganisms found in the aneurysm sac were Staphylococcus aureus and Salmonella species. Careful debridement of all infected tissue was essential. In the infrarenal aortic and iliac vascular bed, in situ reconstruction was performed only in cases of anticipated "low-grade" infection. Alternative revascularization with extra-anatomic procedures (axillobifemoral or femorofemoral crossover bypass graft) was carried out in eight of 16 cases. All four suprarenal and all 13 mycotic aneurysms of the thoracoabdominal aortic segment were repaired in situ. Antibiotics were administered perioperatively, and all patients were subsequently treated with long-term antibiotics. RESULTS In-hospital mortality was 36% (n = 12). Because of the smallness and heterogeneity of the sample, we could not demonstrate significant evidence for any influence of aneurysm location or type of reconstruction on patients' outcome. However, survival was clearly influenced by the status of rupture. During long-term follow-up (mean, 30 months; range, 1-139 months), 10 patients (48%) died-one (4.8%) probably as a consequence of the mycotic aneurysm, the others for unrelated reasons. Eleven patients (52%) are alive and well today, with no signs of persistent or recurrent infection. CONCLUSIONS A mycotic aneurysm of the aortic iliac region remains a life-threatening condition, especially if the aneurysm has already ruptured by the time of surgery. Although the content of the aneurysm sac is considered septic, as was proved by positive cultures in 85% of our patients, in situ reconstruction is feasible and, surprisingly, was not more closely related to higher morbidity and mortality in our series than ligation and extra-anatomic reconstruction, although most of the aneurysms repaired in situ were located at the suprarenal and thoracoabdominal aorta. We assume that our operative mortality rate of 36%, which relates to a rupture rate of 85%, could be substantially lowered if the diagnosis of mycotic aneurysm were established before rupture.

Abstract
INTRODUCTION Primary bacterial infection of an artery is difficult to diagnose, especially at the beginning of the illness. Most of the patients come for emergency treatment in the phase of rupture. METHODS The course of illness in four patients serves as background for discussion of the problems of diagnosis and therapy. RESULTS Bacterial infection of arteries shows a high rate of complications and, for the aorta, high mortality. CONCLUSION If fever of uncertain origin is combined with pain of the stomach or of the back, or with a painful reddish swelling on a limb, this rare disease should be considered in the differential diagnosis.

Abstract
To define the epidemiology, pathogenesis, pathology, presentation, and management of tuberculous mycotic aneurysm of the aorta (TBAA) in the therapeutic era, we reviewed all of the cases reported in the English language literature from 1945 to the present. To the 39 cases in the published literature, we add two cases of our own. Although it is exceedingly rare, the prevalence of this lesion has remained relatively constant. In 75% of the cases, TBAA appeared to result from erosion of the aortic wall by a contiguous focus; 25% from direct seeding of the aortic intima or of the adventitia or media (via the vasa vasorum). Most of the aneurysms were saccular (90%) and false (88%). The thoracic and abdominal aortas were affected with equal frequency. The mean (+/- SD) age of the patients was 50+/-16 years. Twenty-two were men, and 19 were women. In 63% of the cases, tuberculosis (TB) was diagnosed at presentation. Disseminated TB was present in 46% of the cases. One or more of three clinical scenarios suggested TBAA: persistent pain, major bleeding, and a palpable or radiographically visible para-aortic mass, especially if it is expanding or pulsatile. In turn, each of these findings suggested a complication of TBAA that may be an indication for surgical intervention. Among the patients who were offered both medical and surgical treatment, 20 of 23 (87%) survived. Among those who were offered only one form of treatment or were offered no treatment at all there were no survivors. Both in situ reconstruction with a prosthetic graft, and extra-anatomic bypass appeared to offer excellent results, provided that an effective regimen of antituberculous drugs was delivered postoperatively. We offer our conclusions: (1) symptomatic TBAA is a rare but uniformly fatal lesion if not diagnosed promptly, (2) in the context of active TB, and especially miliary TB, TBAA should be suspected whenever one or more of the three clinical scenarios are present, and (3) combined medical and surgical therapy appears to offer the best chance of a cure.

Abstract
OBJECTIVE Recent findings with cryopreserved heart valve allografts in the treatment of infectious endocarditis suggest that the use of cryopreserved arterial allografts may improve the outcome in patients with vascular infections. METHODS Seventy-two patients with mycotic aneurysms (n = 29) or infected vascular prostheses (n = 43) of the thoracic (n = 26) or abdominal aorta (n = 46) were treated with in situ repair and extra-anatomic reconstruction using prosthetic material (n = 38) or implantation of a cryopreserved arterial allograft (n = 34). Disease-related survival and survival free of reoperation were assessed. Morbidity, cumulative lengths of intensive care, hospitalization, antibiotic treatment, and costs were calculated per year of follow-up. RESULTS The use of cryopreserved arterial allografts was superior to conventional surgery in terms of disease-related survival (P =.008), disease-related survival free of reoperation (P =.0001), duration of intensive care per year of follow-up (median 1 vs 11 days; range 1 to 42 vs 2 to 120 days; P =.001), hospitalization (14 vs 30 days; range 7 to 150 vs 15 to 240 days; P =.002), duration of postoperative antibiotic therapy (21 vs 40 days; range 21 to 90 vs 60 to 365 days; P =.002), incidence of complications (24% vs 63%; P =.005), and elimination of infection (91% vs 53%; P =.001). In addition, costs were 40% lower in the group treated by allografts (P =.005). CONCLUSIONS The use of cryopreserved arterial allografts is a more effective treatment for mycotic aneurysms and infected vascular prostheses than conventional surgical techniques.

Abstract
Twenty-four patients who underwent surgery for pararenal aortic aneurysms between January 1992 and April 1997 are reviewed. Eighteen patients had primary atherosclerotic aneurysms, three patients had symptomatic infected aneurysms, two patients had an aneurysm proximal to a prior aortic repair, and one patient had a pseudoaneurysm of a proximal aortic graft anastomosis. Thirteen patients underwent elective operation, five had an urgent operation, and six patients underwent an emergency procedure. Five patients had the proximal aortic clamp placed between the renal arteries (Group I), three patients had it placed between the superior mesenteric and the renal arteries (Group II), and 16 patients had it placed in a supraceliac location (Group III). Aneurysm size, age, sex, preoperative blood chemistries (including hemoglobin, hematocrit, liver function studies, and coagulation studies) were similar in all groups. Two patients in Group III were on hemodialysis preoperatively. Preoperative renal function (blood urea nitrogen and creatinine) was the same in all groups. Visceral ischemic time was 43.4 +/- 9.37 min to the distal kidney in Group I, 26.6 +/- 7.63 min in Group II, and 24.5 +/- 6.22 min in Group III. Mean transfusion requirements were similar in all groups. Two patients in Group I required postoperative hemodialysis. No patient in either Group II or III developed renal insufficiency. Mortality was the same in each group but was related to the urgency of operation (elective 7.6%, urgent 40%, emergent 50%). Intrarenal clamping (Group I) was associated with more renal and gastrointestinal complications than either suprarenal or supraceliac clamping. Although suprarenal and supraceliac clamping had similar results, our preference is supraceliac clamping because it is technically easy to achieve and is associated with few end-organ complications.

Abstract
BACKGROUND We report results of infected aortic aneurysms treated by a single group over 20 years. METHODS Retrospective review. RESULTS Seventeen patients were treated, 10 with infrarenal and 7 suprarenal infections. All had abdominal/back pain, 88% were febrile, 71% had leukocytosis, and 24% were hemodynamically unstable. The most common responsible organism was Staphylococcus aureus (29%) followed by Salmonella organisms (24%). All suprarenal infections were gram-positive organisms. Infrarenal infections were treated with preliminary axillofemoral bypass followed by aortic resection. Suprarenal infections were treated with either in situ prosthetic graft or patch repairs. Operative survival was 90% for infrarenal and 57% for suprarenal infections. Operative deaths occurred in the setting of overwhelming sepsis and/or severe preoperative hemodynamic instability. There was no limb loss, renal failure, or intestinal ischemia. Late deaths occurred in 4 patients at 1.3 to 6.3 years postoperatively and were unrelated to their aortic repairs. Nine patients remain alive with a median follow-up of 2 years. There have been no late aortic or graft infections. CONCLUSIONS In the absence of hemodynamic instability and uncontrolled sepsis, infected aortic aneurysms can be successfully repaired with durable results.

Abstract
From 1976 to 1994 we performed surgical treatment of 18 infected aneurysms of the infrarenal abdominal aorta. The aneurysm had ruptured in nine patients: into the retroperitoneum in six patients, and into an adjacent structure in three patients (duodenum, inferior vena cava, left renal vein). Two patients had an associated spondylitis. Four patients were in shock at the time of surgical treatment. Six patients (including four patients with Salmonella infection and two patients with spondylitis) had positive preoperative blood cultures. Salmonella was the most common microorganism (27%). Anaerobes accounted for 16%. In situ replacement was performed in 13 patients including three procedures performed under emergency conditions with frank purulent infection. Extraanatomic bypass was performed in five patients. Early postoperative death occurred in two patients (11%) due to septic complications (rupture of aortic anastomosis in one patient and rupture of aortic stump in one patient). All surviving patients underwent prolonged antibiotic therapy for at least 6 weeks. Overall mortality secondary to infected aneurysm was 16%. Infection of the aortic graft occurred in four patients (38%) including two patients with Salmonella infection and one patient with spondylitis. One patient developed a false anastomotic aneurysm 6 months postoperatively and was treated by in situ arterial allograft replacement. Postoperative blood cultures were positive in two patients presenting spondylitis and infection of the aortic prosthesis occurred in one of these patients. In addition to rupture, poor prognostic factors included spondylitis and Salmonella infection that were found to greatly enhance the risk of postoperative graft infection following in situ reconstruction.

Abstract
Twelve patients with rupture of the perivisceral abdominal aorta were admitted to the UCLA Medical Center between 1984 and 1996. Six patients had atherosclerotic thoracoabdominal aneurysms (TAA) which ruptured in the visceral segment of the aorta. The remaining 6 patients proved to have ruptured mycotic aneurysm (MA). Clinical presentation was different in the two groups. Whereas all 6 patients with TAA and < 24 hr history of abdominal, chest, or back pain, patients with MA had these symptoms for 2-5 weeks (mean 3.4 weeks). History of sepsis was present in 4/6 MA and in 0/6 TAA patients. No difference in risk factors for atherosclerosis were seen between these two groups. Clinical outcomes were also different. Operation consisted of in situ vascular grafting in all patients. Operative mortality for TAA was 33% (2/6), whereas all patients with MA survived repair with no operative mortality. Two patients had cardiac arrest prior to surgery. One of these had a TAA and died 5 days after surgery, whereas the other survived repair of an MA. Follow-up ranges from 1-84 months (mean 48 months). Four survivors in the TAA group are alive at 6, 8, 14, and 84 months, with the latter having a pseudoaneurysm of the visceral patch-graft anastomosis. All 6 patients with MA are alive at 1-73 months (mean 39 months) without evidence of graft sepsis or recurrent aneurysm. We conclude that rupture of the visceral portion of the aorta is often associated with a mycotic process, with important differences noted in clinical presentation when compared to atherosclerotic TAA. Surgical intervention is effective in both MA and TAA. Operative mortality, however, is significantly higher in patients with ruptured TAA. In situ prosthetic replacement for ruptured MA is associated with low mortality and excellent long-term results.

Abstract
BACKGROUND Despite the improvements achieved in antibiotic therapy, severe aortic infection resulting in mycotic aneurysms is still a highly lethal disease and surgical management remains a challenging task. PATIENTS AND METHODS A total of 43 patients with severe aortic infections were analyzed and separated in four groups: (1) Infections of the aortic root Ventriculo-aortic disconnection due to deep aortic infection (6 patients). Two patients were operated using homo-composit grafts. Of the 6 patients total, one died early and two died late during a mean follow-up of 6 years. The two patients with homografts are still alive. (2) Infections of the ascending aorta and the aortic arch. In situ repair for mycotic aneurysmal lesions of the ascending aorta was performed in 6 patients using synthetic graft material in 4/6, biological material in 1/6 and direct suture in 1/6. Two patients had to be reoperated; one of them died early. There was no recurrent infection during a mean follow-up of 6 years. (3) Infections of the descending thoracic and thoraco-abdominal aorta in-situ repair for mycotic aneurysmal lesions of the descending and thoraco-abdominal aorta was performed in 12 patients using homografts in five. Two patients died early and two other patients died late during a mean follow-up of 6 years. (4) Infections of the infrarenal abdominal aorta. In this series of 19 patients with mycotic infrarenal aortic aneurysms, in situ reconstruction was performed in 12 (5/12 with homografts) and extra-anatomic reconstruction (axillo-femoral bypass) was performed in 7. Hospital mortality was 5/19 patients and another 5/19 patients died during a mean follow-up of 6 years. One of the early deaths was due to aortic stump rupture. Two patients with axillo-femoral reconstructions were later converted to descending-thoracic-aortic-bifemoral bypasses. Five thromboses of axillo-femoral bypasses were observed in three of the seven patients with extra-anatomic repairs. RESULTS Infections of the aortic root, the ascending aorta and the aortic arch are approached with total cardio-pulmonary bypass, using cardioplegic myocardial protection and deep hypothermia with circulatory arrest if necessary. Proximal unloading and distal support using partial cardiopulmonary bypass is preferred for repair of infected descending and thoracoabdominal aortic lesions, whereas no such adjuncts are required for repair of infected infrarenal aortic lesions. CONCLUSIONS The anatomical location of the aortic infection and the availability of homologous graft material are the main factors determining the surgical strategy.

Abstract
Twelve patients with infected aneurysms of the thoracic and abdominal aorta were evaluated. Aneurysmal location, aetiology, bacteriology and treatment modality were analysed to determine the relationship between these factors and outcome. Patients were divided into two groups based on the preoperative states of their infections. Group 1 patients (n = 7) underwent resection after resolution of their active infection. The causative organisms included Staphylococcus epidermidis (two cases). Salmonella spp. (one). Acinetobacter (one), Mycobacterium tuberculosis (one) and unknown organisms (two). Group 2 patients (n = 5) required urgent surgery because of uncontrolled sepsis despite intensive treatment with antibiotics. The causative organisms included Staphylococcus aureus (two cases). Pseudomonas aeruginosa (two) and Salmonella spp. (one). In group 1, three patients underwent closed en bloc excision of the aneurysm with in-situ graft replacement, and four underwent partial resection with in-situ graft replacement. In group 2, three patients underwent resection of the aneurysm with ligation of aorta and extra-anatomic bypass, and two underwent in-situ graft replacement after débridement of infected tissue. Overall, patients in group 1 had a mortality rate of 14% compared with 80% in group 2. These results suggest that the operative approach and method chosen to restore arterial continuity have less of an impact on outcome. The primary determinants of outcome are virulence of the infecting organism and the preoperative state of the infection.

Abstract
We report a 5 year experience of 10 cases of mycotic aneurysms of the aorta caused by salmonella infection. Of the 10 patients, nine were males and one was female in an age range from 60 to 80 years with a mean of 71 years. The major clinical manifestations were fever, abdominal or back pain, pulsatile abdominal mass and leucocytosis. The diagnosis was based on clinical symptoms and signs and positive blood or tissue cultures. The main confirmatory procedure was computed tomography (CT). Two year survival rate was 20%. Five patients died during hospitalisation, without surgery. Three patients died within 2 months of surgery. The other two patients, treated surgically and by intensive antibiotic therapy, survived. Death resulted usually from recurrent infection and graft leakage. Contrary to previous reports, salmonella mycotic aneurysm is still common in this geographical area and the prognosis is poor.

Abstract
Six infective endocarditis patients who developed cerebral bacterial aneurysm were reviewed to clarify the indications and timing for cerebral angiography to achieve early detection of unruptured aneurysms. All cerebral bacterial aneurysms were confirmed either angiographically or at autopsy. All patients were treated conservatively. Four patients died due to ruptured aneurysm. Four of the six patients showed the signs and symptoms of cerebral and/or systemic embolism, followed by rupture or detection of cerebral bacterial aneurysm. Prodromal signs and symptoms of embolism in patients with infective endocarditis should be considered as indicators for cerebral angiography to detect cerebral bacterial aneurysms before rupture.

Abstract
Direct graft replacement with local debridement and prolonged administration of antibiotics was used in the treatment of six patients with mycotic thoracoabdominal aneurysms. The only early death occurred in a patient with systemic sepsis related to Staphylococcus aureus mycotic suprarenal aneurysm. Long-term survival of the remaining patients has been excellent: two patients died of unrelated causes at 5 and 6 years, respectively; one patient remains alive with known persistent infection at 5 years; and the remaining patients are alive with no evidence of infection at 1 1/2 and 10 years, respectively. Percutaneous aspiration of infected perigraft fluid with local instillation of antibiotics along with administration of intravenous antibiotics may provide palliation in selected patients with recurrent infections. In view of the magnitude of the problems associated with recurrent infection, life-time administration of antibiotics is recommended after in situ graft replacement of mycotic thoracoabdominal aneurysms.

Abstract
The authors present the results of treatment of six inflammatory aneurysms in the material of 53 aneurysms treated surgically in the years 1987-1992. Direct results of surgical treatment, hospitalization period, and peri-operational complications are the subject of analysis. Peri-operational mortality of the patients with inflammatory aneurysm was higher than that of patients with non-inflammatory aneurysm, undergoing elective surgery. Higher incidence of peri-operational complications indicates higher operational risk of inflammatory aneurysm.

Abstract
Twenty-five infected infrarenal aortic aneurysms operated on between 1968 and 1989 were reviewed. They were classified into post-embolic (mycotic) aneurysms (group I), infective aortitis (group II), and infected atherosclerotic aneurysms (group III). Aortoduodenal fistulas were found in eight patients and aortocaval in two. Five patients were operated on in a state of shock, and 12 had preoperative positive blood cultures. Surgical procedures included in situ reconstruction of the aorta (n = 21) and extra-anatomic bypass associated with aneurysmal resection (n = 4). In 19 patients, prostheses were covered with omental flaps, and antibiotics were continued for more than 6 weeks in all patients. In patients who underwent in situ reconstruction, three deaths were related to the initial surgery. All surviving patients were regularly followed up, and none showed any sign of late septic recurrence. In patients who underwent extra-anatomic bypass, two died in the postoperative period, one underwent reoperation 2 years after the initial surgery, and the last patient is doing well. Positive postoperative blood cultures (n = 4) revealed persistent sepsis: two cholecystitis, one spondylitis, and one aortic infection. An exhaustive review of the literature was performed; clinical, bacteriologic, and operative features and results were analyzed; prognostic factors were evaluated; and a practical therapeutic approach was suggested. The importance of preoperative diagnosis, complete resection, debridement of infected tissues, omental flap coverage, and long-term antibiotic therapy with regular computerized tomographic scanning follow-up is stressed.

Abstract
More than 200 intraventricular haematomas (IVH) have been treated in the Homburg Neurosurgical University Clinic since computed tomography was available and facilitated the diagnosis. Among 200 consecutive cases, which are analysed and presented in this publication, there were 71 patients with subarachnoid haemorrhage (SAH)--58 of whom with angiographically and/or pathologically verified aneurysms--, and 21 cases with intraventricular angiomas. IVH without concomitant intracerebral haematoma (ICH) and without evidence of SAH is highly suggestive of intraventricular angioma. In our experience panangiography [if available digital subtraction angiography (DAS)] should be done as soon as possible in all cases of IVH. It is a precondition for early diagnosis and operative elimination of the source of bleeding, because the retrospective analysis of our material shows that rebleeding is by far the highest single risk factor in cases with IVH caused by aneurysms or angiomas. We therefore recommend early microsurgical occlusion of the aneurysms and exstirpation or intravascular embolisation of the angioma. The best survival rate (76%) was achieved in IVH cases caused by angiomas. In aneurysms with IVH the survival rate was 35%, in IVH caused by other diseases 37%. The worst prognosis occurs in SAH with IVH without proven aneurysm or angioma. The survival rate of this group was only 8%.

Abstract
Between 1973 and 1991, 12 patients with mycotic aneurysm of the abdominal aorta underwent operation. There were four elective and eight emergency procedures. In situ reconstruction was performed in six patients and extra-anatomic reconstruction with axillobifemoral bypass grafting in six. The hospital mortality rate was 25% (three patients) and another three died during the follow-up period of mean 5.5 years. Descending aorta-bifemoral bypass was performed in two patients without signs of chronic local infection 1 and 2 years after previous axillobifemoral bypass. Late complications were peripheral embolization in one patient after in situ reconstruction and a total of five thromboses of the axillofemoral bypass in three patients. Extra-anatomic bypass grafting remains the method of choice for the majority of patients with mycotic aneurysm of the abdominal aorta. In situ reconstruction seems to be an appropriate procedure for a highly selected group of patients.

Abstract
Between 1969 and 1990 six patients (aged 14 to 64 years, mean 43 years) underwent in situ reconstruction for mycotic aneurysm of the ascending aorta. The primary source of infection was endocarditis in three patients (subacute bacterial endocarditis [n = one patient], sepsis with acute endocarditis [n = one patient]), sepsis with sternal osteomyelitis in one, sepsis with purulent pericarditis in one, and generalized febrile illness in one. In five of six patients the treatment consisted of the excision of changed tissue combined with a composite graft (n = one patient), a xenopericardial patch repair (n = one patient), a Dacron graft repair and aortic valve replacement (n = one patient), a Dacron graft repair alone (n = one patient), and a lateral suture combined with double valve replacement (n = one patient). In one patient with perforation of the mycotic aneurysm into the pulmonary artery, the place of rupture was oversewn without excision of the aortic or pulmonary artery tissue. Two patients with local pericardial inflammation were reoperated on during the hospital stay; one of them because of recurrent mycotic aneurysm of the ascending aorta at the other location and the other because of infection of the suture line after the Dacron patch repair. Antibiotic therapy was intravenously administered for 2 to 12 weeks postoperatively and continued orally for 4 to 8 weeks. The mean observation time was 6 years (range 4 months to 16 years). There was no late graft infection, except the chronic infection of the suture line in one patient who died suddenly 4 months after the operation. There was no early death, and there were three late deaths (chronic myocardial failure, one patient, chronic renal failure, one patient, sudden death, one patient). We concluded that in situ reconstruction for mycotic aneurysm of the ascending aorta combined with prolonged antibiotic therapy is an appropriate procedure with satisfactory early and good long-term results.

Abstract
Twenty-seven patients with mycotic aneurysms of the aorta and its major branches were operated on between 1969 and 1991. There were 24 males and three females ranging in age from 6 to 84 years (mean age for adults 63 years). Sixteen of the 27 (59%) aneurysms were ruptured and in situ repair was undertaken in 20 (74%) patients. The mean follow-up was 5.8 years (range: 8 months to 16 years). Four patients (15%) died during the hospital stay and 23 survived. There were eight late deaths, two of which were a direct result of the aneurysm. The estimated 1- and 5-year survival rates were 62 and 36%, respectively. Extra-anatomic reconstruction is the method of choice for the majority of patients with mycotic aneurysm of the infrarenal abdominal aorta and iliac arteries. In situ repair after an extensive debridement of the aneurysmal wall and all infected tissue combined with antibiotic therapy is a satisfactory method of treating mycotic aneurysms of other locations, and for a highly selected group of patients with infrarenal mycotic aortic aneurysms.

Abstract
In a retrospective analysis 12 patients treated for aorto-femoral vascular infections between 1984 and 1990 were evaluated. They were all male with a mean age of 63 years. Indications for treatment were: mycotic aneurysms-3, primary aorto-enteric fistula-2 and graft infection-7. Surgical treatment consisted of implantation of an extra-anatomic bypass, carefully avoiding the infected area, followed by removal of the infected graft and tissue at the same session. There was no early mortality (less than 30 days) but the first year mortality was 42% (n = 5). Causes of death were: aortic stump disruption (n = 1), recurrence of aorto-enteric fistula (n = 2), axillary anastomosis disruption (n = 1), cardiac failure (n = 1). Orthotopic reconstruction of the aorta after 12 months, as we advocate, was accomplished in two patients and is scheduled in another one. In two patients their poor condition precluded this second step, and in two further patients above-knee amputation with subsequent extra-anatomic graft removal was needed. Only one of the 12 extra-anatomic bypasses became infected. Reconstruction by axillo-femoral bypass combined with removal of the aorto-femoral graft at the same session is a practicable procedure with good early results. However, the rate of successful orthotopic reconstruction of the aorta after 12 months is low because of a high mortality rate, especially in the presence of aorto-enteric fistulas, and because some patients with well functioning axillo-femoral grafts are in too poor condition for another large operation.
