Abstract
Background Dysphagia aortica is an umbrella term to describe swallowing obstruction from external aortic compression secondary to a dilated, tortuous, or aneurysmal aorta. We performed a systematic literature review to clarify clinical features and outcomes of patients with dysphagia aortica. Materials and methods We searched PubMed, EMBASE, Web of Science, and the Cochrane Library. The terms “aortic dysphagia,” “dysphagia aortica,” “dysphagia AND aortic aneurysm” were matched. We also queried the prospectively updated database of our esophageal center to identify patients with aortic dysphagia referred for diagnosis and treatment over the past two decades. Results A total of 57 studies including 69 patients diagnosed with dysphagia aortica were identified, and one patient from our center was added to the database. The mean age was 72 years (range 22–98), and the male to female ratio 1.1:1. Of these 70 patients, the majority (n = 63, 90%) had an aortic aneurysm, pseudoaneurysm, or dissection. Overall, 37 (53%) patients received an operative treatment (81.1% a vascular procedure, 13.5% a digestive tract procedure, 5.4% both procedures). Thoracic endovascular aortic repair (TEVAR) accounted for 60% of all vascular procedures. The postoperative mortality rate was 21.2% (n = 7/33). The mortality rate among patients treated conservatively was 55% (n = 11/20). Twenty-six (45.6%) studies were deemed at a high risk of bias. Conclusion Dysphagia aortica is a rare clinical entity with high morbidity and mortality rates and no standardized management. Early recognition of dysphagia and a high suspicion of aortoesophageal fistula may be lifesaving in this patient population.

Abstract
Spinal cord complications including paraplegia and partial neurologic deficits remain a frequent problem during repair of descending thoracic or thoracoabdominal aortic aneurysms. Effective prevention of this dreaded complication is of paramount importance. Among the many adjuncts that have been proposed to prevent spinal cord complications, spinal fluid drainage is one that has been used by numerous teams. The aim of this review is to answer the following question: does spinal fluid drainage afford spinal cord protection during both open and endovascular repair of thoracic or thoracoabdominal aortic aneurysms?

Abstract
Purpose: To compare the results of thoracic endovascular grafting of different aortic segments performed with commercially available stent-grafts. Methods: Between January 1999 and October 2006, 178 patients (150 men; mean age 69.4±10.2 years) underwent endovascular grafting of the thoracic aorta (68 hybrid procedures) with commercially produced stent-grafts from 4 manufacturers. Patients were divided into 3 groups according to the aortic segment involved: 64 aortic arch cases (37 hybrids for supra-aortic trunks revascularization), 100 descending thoracic aorta (DTA) cases (17 hybrid: 12 for access and 5 for associated abdominal aortic aneurysm), and 14 thoracoabdominal aorta (TaA) patients excluded from conventional repair (14 hybrids for renal and splanchnic revascularization). Results: The technical success was 93.8% (167/178). Overall 30-day mortality was 5.6% (10/178). There were 10 (5.6%) type I endoleaks. Initial clinical success was 88.2% (157/178). At a mean follow-up of 29.3±21.2 months, the midterm clinical success was 89.9% (160/178). In the arch group, the technical success was 85.9% (55/64). Thirty-day mortality was 6.3% (4/64). There were 8 (12.5%) type I endoleaks. Initial and midterm clinical success rates were 79.7% (51/64) and 85.9% (55/64), respectively. In the 100-patient DTA group, the technical success was 98.0%. Thirty-day mortality was 2.0%. The type I endoleak rate was 2.0%. Clinical success was 96.0% initially and 95.0% at midterm. All 14 of the TaA cases were completed successfully, but 30-day mortality was 28.6% (4/14). There were no type I endoleaks. Clinical success rates initially and at midterm were both 71.4% (10/14). Conclusion: Over the last 6 years, synergy between endovascular and surgical procedures allowed treatment of all segments of the thoracic aorta. Overall perioperative and medium-term results were reasonably favorable; however, they were more satisfactory when the descending thoracic aorta alone was involved. Hybrid procedures allowed treatment of all aortic segments, but they decreased the success rates significantly. Endovascular grafting is currently our preferred method of treating pathologies involving the DTA and aortic arch, while our data suggest limiting the use of stent-grafts to high-risk patients or compassionate indications when the thoracoabdominal aorta is involved.

Abstract
We present a case of a patient with Crawford type IV aortic thoracoabdominal aneurysm. The patient underwent hybrid repair in two stages. Initially a Dacron(r) graft was implanted surgically with revascularization of all visceral branches from the left external iliac artery (debranching). On a later date, the second stage of treatment was with an endovascular technique with bi aorto-iliac endoprosthesis. After 2 years the patient remains asymptomatic and in full working activity.

Abstract
BACKGROUND Thoracoabdominal aortic aneurysm (TAAA) hybrid repair consists of aortic visceral branch rerouting followed by TAAA endograft exclusion. This technique has been shown to represent a technically feasible strategy in selected patients. METHODS We analyzed 52 high-risk patients who underwent hybrid TAAA repair between 2001 and 2012 in our centre with a variety of visceral rerouting configurations and of commercially available thoracic endografts. Thirty-seven simultaneous (71.2%) and 15 staged procedures (21.8%) were performed with a four-vessel revascularization in 18 cases (34.6%), a three-vessel revascularization in 11 cases (21.2%) and a two-vessel revascularization in 23 cases (44.2%). RESULTS No intraoperative deaths were observed. We recorded a perioperative mortality rate of 13.5% (n=7), including deaths from multiorgan failure (n=2), myocardial infarction (n=2), coagulopathy (n=1), pancreatitis (n=1) and bowel infarction (n=1). Perioperative morbidity rate was 28.8% (n=15), including 2 cases of transient paraparesis and 1 case of permanent paraplegia. Renal failure (n=5), pancreatitis (n=3), respiratory failure (n=3) and dysphagia (n=1) were also observed. At median follow-up of 23.9 months procedure-related mortality rate was 9.6%: two patients died from visceral graft occlusion and three from aortic rupture. There were three endoleaks and one endograft migration, none of which resulted in death. Five patients (9.6%) died as a consequence of unrelated events. CONCLUSIONS Typical complications of conventional TAAA open surgery have not been eliminated by hybrid repair, and significant mortality and morbidity rates have been recorded. Fate of visceral bypasses and incidence of endoleak and other endograft-related complications needs to be carefully assessed. Hybrid TAAA repair should currently be limited to high-risk surgical patients with unfit anatomy for endovascular repair.

Abstract
Thoraco-abdominal aortic aneurysm repair remains a formidable challenge to vascular surgeons. The traditional repair of thoraco-laparotomy with aortic cross-clamping is associated with a high morbidity and mortality despite significant advances in perioperative critical care, anaesthetic and surgical techniques. The advent of the endovascular revolution has shown a marked paradigm in the approach to all aneurysm repairs. As a logical progression from the open repair, the St Mary's visceral hybrid repair combines traditional open techniques (retrograde visceral and renal revascularisation via mid-line laparotomy) with endovascular stent grafting, thereby avoiding the need for thoracotomy and aortic cross-clamping. In specialist centres, the results have been encouraging and easily comparable to the open repair. The technique has been used in several centres around the world and represents a robust, transferrable method of repairing thoraco-abdominal aortic aneurysms. Stent-grafting technologies have reached a point of sophistication that wholly endovascular methods of repairing thoraco-abdominal aortic aneurysms are being performed in several centres around the world. Although these stent grafts have to be customised to the individual patient and are only suitable for certain types of aneurysmal anatomies, they represent the future of thoraco-abdominal aortic aneurysm repair. We review the history of thoraco-abdominal aortic aneurysm repair, the exciting advances in their treatment and discuss our approach to the management of thoraco-abdominal aortic aneurysms in the 21st century.

Abstract
Hybrid surgical and endovascular approaches such as open visceral vessel debranching and subsequent endovascular exclusion of thoracic abdominal aortic aneurysms (TAAA) represents a significant development in treatment of TAAAs. As compared to traditional endovascular aneurysm repair, hybrid repairs commonly have a higher rate of endoleak and other endograft-related complications. In this report, we present a 71 year-old man with significant comorbidities including chronic obstructive pulmonary disease, hypertension and prostate cancer. The patient after undergoing debranching of the thoracic arch followed by endograft repair of an arch aneurysm developed a proximal type I and type II endoleak fed by the previously ligated left subclavian artery. Despite coiling of the left subclavian artery and proximal extension of the endograft, a type I endoleak persisted. Several months after the left subclavian artery was coiled, a catheter was advanced through the coils and beyond the site of ligation directly into the aneurysmal sac. Once in the aneurysmal sac, multiple coils were deployed resulting in successful treatment of the type I endoleak. This report highlights the unique challenges in treating proximal descending thoracic aneurysms and represents the first report of the treatment of a type I endoleak with reaccess through a previously coiled vessel for deployment of embolics directly into the aneurysmal sac.

Abstract
The risks of purposeful celiac artery coverage during endovascular thoracic aortic aneurysm repair (TEVAR) to obtain an adequate distal landing zone have received scant scientific attention. Patients undergoing TEVAR at 6 tertiary centers from January 2000 to June 2007 were identified (n = 434); cases requiring celiac artery exclusion (n = 19; 4.4% of the total) were analyzed. The mean follow-up was 8.7 months (range, 0.2-21.2). The mean patients' age was 73.6 years (range, 56-86); 57.9% were men. The mean aneurysm diameter was 6.7 cm (range, 5-8.6). In 2 patients, the celiac artery balloon occlusion test was performed prior to TEVAR. In both, intact collateral foregut circulation was seen. Both underwent TEVAR without celiac artery revascularization; 1 did well, whereas the other developed foregut ischemia. In 16 cases (84.2%), the celiac artery was not revascularized prior to TEVAR. In those patients, 19 complications were reported (3 deaths; 2 paraplegia). No similar events occurred in those who underwent celiac artery revascularization (n = 3). Celiac artery coverage during TEVAR is required in 4.4% of cases. TEVAR correlated with a nonnegligible number of major complications. Complications were more frequent and severe in patients who did not have celiac artery revascularization prior to TEVAR. Specific celiac artery coverage complications are rare and not readily predictable based on preprocedure arteriography.

Abstract
Introduction of endografting has significantly changed the treatment options of aortic aneurysms; they can be successfully applied for aortic arch or thoracoabdominal aorta aneurysm repairs, as well. In order to create safe landing zones for the endografts on these segments, a modification of the original anatomy is needed using transpositions and/or bypasses, which is called "debranching". These hybrid procedures that combine traditional and endovascular techniques may reduce surgical trauma and offer solution for patients being unfit for major surgery. We carried out a hybrid intervention in a lady who had a 60 mm Crawford Type IV aortic aneurysm including the orifice of the celiac trunk. First, an aorto-splenic artery PTFE bypass was performed and the celiac trunk was oversewn proximally to its trifurcation. The spleen remained viable through the gastroepiploic artery. Four days thereafter we covered the aneurysm using a 34 mm Thoracic Excluder. The patient tolerated both procedures well, and was discharged in stable condition. One year after this intervention, a follow-up CT scan confirmed the good position of the endograft, no endoleak and involution of the aneurysm was detected. Good patency of the aorto-splenic artery bypass was seen. This was the first thoracoabdominal hybrid surgery case performed in Hungary.

Abstract
PURPOSE To report the results of a systematic review of the literature and to provide evidence for the hybrid open-endovascular repair (HOER) in patients with thoracoabdominal aortic aneurysms (TAAAs). METHODS A comprehensive literature review was performed and all studies identified that reported the results of HOER in patients with TAAA and information about primary technical and clinical success in evaluating the immediate and long-term complications such as neurological, renal and respiratory morbidity. All studies were reviewed by two independent observers for the above mentioned parameters. RESULTS After careful selection according to the given criteria, 13 studies were included in our statistical analysis. The number of reported patients totalled 58. Of those, 37 were men (64.4%) and the mean age of the patients was 68.1 years (range 35-80, 95%CI [72.8, 64.9]). All patients were unfit for open repair with severe comorbidities. The mean follow-up period was 14.5+/-8.7 months (range 4-36, 95%CI [18.7, 9.9]) and the mean aneurysm diameter was 7.15cm (range 5 to 12, 95%CI [7.87, 6.69]). 229 (97.8%) of the 234 visceral vessel grafts remained patent during the follow-up period. Reintervention was necessary in one (1.6%) of the five patients with an occluded graft. The overall long-term endoleak rate was 20.6% (12/58 patients) and the reintervention rate was 13.7% (8/58 patients). No patients developed procedure-related neurological deficits. The overall early and long-term mortality rate for completed procedures was 15.5% (9/58). CONCLUSIONS HOER shows promising mid-term results for high-risk patients who have TAAA, however, present evidence does not allow robust conclusions.

Abstract
OBJECTIVE The hybrid approach to the repair of thoracoabdominal aortic aneurysm (TAAA), consisting of visceral aortic debranching with retrograde revascularization of the splanchnic and renal arteries and aneurysm exclusion using stent grafts, has been previously described and may be considered particularly appealing in high-risk patients, especially those who have undergone prior aortic surgery. This study analyzed prospectively recorded data of a series of high-risk patients with prior aortic surgery who underwent hybrid TAAA repair at our institute and contrasted the outcomes with those of a similar group of patients who underwent conventional open TAAA repair. METHODS Between 2001 and 2006, 13 patients (12 men) with a median age of 69.6 years (range, 35 to 82 years) underwent one-stage hybrid repair of TAAA (7 type I, 2 type II, 2 type IV, and 2 aneurysms of the visceral aortic patch). These patients, the hybrid group, had a history of aortic surgery (30.7% ascending, 30.7% descending, 46.1% abdominal aortic repair, and 15.4% redo TAAA) and were at high risk for open repair. The criteria used to define these patients as high risk and to indicate the need for hybrid treatment were American Society of Anesthesiologists (ASA) class 3 or 4 associated with a preoperative forced expiratory volume in 1 second (FEV1)<50%. In all cases, we accomplished partial or total visceral aortic debranching through (1) a previous visceral artery retrograde revascularization with synthetic grafts (single bypass, customized Y or bifurcated grafts), and (2) aortic endovascular repair with one of three different commercially produced stent grafts (Cook, W.L. Gore & Assoc, and Medtronic). We analyzed the results and compared the outcomes of the hybrid group with those of a similar group of 29 patients (25 men) with a median age 65.3 years (range, 58 to 79) selected from our overall series of 246 TAAA repairs between 1988 and 2005. These 29 patients, the conventionally treated group, were selected for having had aortic surgery (22% ascending, 38% descending, 42% abdominal aortic repair, and 10.3% redo TAAA), an ASA 3 or 4, a preoperative FEV1<50%, and a conventional open repair of TAAA (10 type I, 5 type II, 4 type III, 7 type IV, and 3 aneurysms of the visceral aortic patch). RESULTS In the hybrid group, 32 visceral bypasses were completed and endovascular TAAA repair was successful in all cases. No intraoperative deaths occurred. Perioperative mortality was 23%, and morbidity was 30.8% (renal failure in 2, respiratory failure in 1, and delayed transient paraplegia in 1). At a median follow-up of 14.9 months (range, 11 days to 59.4 months), all grafts were patent at postoperative computed tomography angiography and no aneurysm-related deaths, endoleak, stent graft migration, or morbidity related to visceral revascularization had occurred. No conventionally treated patients died intraoperatively. Perioperative mortality was 17.2% and morbidity was 44.8% (respiratory failure in 7, coagulopathy in 1, renal failure in 2, and paraplegia in 3). At a median follow-up of 5.4 years (range, 1.7 to 7.9 years), no significant complications related to aortic repair occurred, except for three patients (10.3%) with asymptomatic dilatation of the visceral aortic patch<5 cm undergoing radiologic surveillance. CONCLUSION Hybrid TAAA repair is technically feasible in selected cases. Perioperative morbidity and mortality were considerable in our subset of high-risk patients with prior aortic surgery, but no aneurysm-related or procedure-related complications were reported at mid-term follow-up. Hybrid TAAA repair did not lead to a significant improvement in outcomes compared with open TAAA repair in a similar group of patients. Larger series are required for valid statistical comparisons and longer follow-ups are necessary to evaluate the durability of hybrid repairs.

Abstract
The availability of thoracic and abdominal endografts has decreased the morbidity and mortality associated with the repair of aneurysms of the aorta. The current limitations of endografts for aneurysms involve adequate proximal and distal landing zones. Branches that are not critical, such as the internal iliac or left subclavian artery, may often be covered and included in the landing zone for most patients, with a few exceptions. However, aneurysms involving critical branch vessels to the brain and intra-abdominal viscera cannot be covered and open repair of aneurysms in these locations carry the highest morbidity and mortality. This review describes the various techniques to relocate these critical branch vessels to expand the use of stent grafts for the treatment of these complex aneurysms.

Abstract
AIM The conventional open repair of thoracoabdominal aneurysms and dissections remains complex and demanding and is associated with significant morbidity and mortality. We present our experience of hybrid open and endovascular treatment of thoracoabdominal aneurysms and dissections. METHODS Within an experience of 226 aortic stent-grafts between 1998 and April 2006, 6 of the patients (median age 60 years, range 35 to 68 years) with thoracoabdominal aneurysms (Crawford type I, II, III, and V) were treated with a combined endovascular and open surgical approach. Five men and one woman, with median aneurysm diameter of 75 mm (range 70-100 mm), received revascularization of the renal arteries, the superior mesenteric artery, and the coeliac trunk accomplished via transperitoneal bypass grafting. Aneurysmal exclusion was then performed by stent-graft deployment. RESULTS The entire procedure was technically successful in all patients. The patients were discharged a median of 9 days after the operation, while the postoperative studies revealed the patency of the vessels and no evidence of type I endoleak or secondary rupture of the aneurysm. During follow up (1 to 22 months) spiral-CT scanning revealed distinct shrinkage of the aneurysm, no graft migration or endoleak and patency of all revascularised vessels, except one renal artery in two patients. No patient experienced any temporary or permanent neurological deficit, and no dialysis was necessary. CONCLUSION The combined endovascular and open surgical approach is feasible, without cross clamping of the aorta and with minimized ischemia time for renal and visceral arteries, and seems to be an appropriate strategy for patients with a thoraco-abdominal aortic aneurysm or dissection.

Abstract
INTRODUCTION We report a case of staged endovascular and hybrid treatment of recurrent thoracoabdominal aneurysms (TAAA) in a 55-year-old HIV-positive man. REPORT A patient, who had previously been surgically treated for a type III TAAA, presented with recurrent aneurysms. The patient was treated by a combination of endovascular and open surgery. Neither visceral nor spinal ischemia were observed. CONCLUSION The hybrid treatment of recurrent TAAA could offer lower mortality and morbidity. Patients with HIV/AIDS treated for aortic aneurysms require close follow-up.

Abstract
BACKGROUND Endovascular therapy is a less invasive alternative treatment for high-risk patients with thoracic aortic aneurysms. However, this technology alone is often not applicable to complex aneurysmal morphology. The purpose of this study was to evaluate the utility of hybrid strategies in high-risk patients who are otherwise unsuitable for endovascular therapy alone. METHODS During an 18-month period, 31 high-risk patients (mean age, 69 years; range, 52-89 years) underwent combined open and endovascular approaches for complex aneurysms, including 16 patients with ascending and arch aneurysms and 15 patients with aneurysms involving visceral vessels. Among them, 11 patients had histories of aneurysm repairs. To overcome the anatomic limitations of endovascular repairs, various adjunctive surgical maneuvers were used, including aortic arch reconstruction in 3 patients, supra-aortic trunk debranching in 13 patients (including 8 patients who required aortas as inflow sources), and visceral vessel bypasses in 15 patients (including 10 patients who required bypasses to all 3 visceral branches). Additionally, carotid artery access was obtained in 1 patient, and iliac artery conduits were created in 12 patients. RESULTS Technical success was achieved in all patients. There was one perioperative death (3.2%) due to postoperative bleeding. Two patients (6.4%) had immediate type II endoleaks, which were resolved by the 1-month follow-up. Other procedure-related complications occurred in three patients (9.6%), including renal bypass thromboses in two patients and retroperitoneal hematoma, which was successfully managed conservatively, in one patient. During a mean follow-up of 16 months, two patients died of unrelated causes, whereas the remainder of patients were asymptomatic, without aneurysm enlargement. CONCLUSIONS Our study highlights how hybrid strategies incorporating surgical and endovascular approaches can be used successfully in treating patients with complex thoracic aortic aneurysms. This combined approach potentially expands the field of endovascular stent grafting and is an attractive solution for patients with poor cardiopulmonary reserves.

Abstract
OBJECTIVE We review our ongoing experience with a transabdominal stent repair of complex thoracoabdominal aneurysms (Crawford type I, II, and III) with surgical revascularization of visceral and renal arteries. METHODS A retrospective review was conducted of prospectively collected data from 29 consecutive patients who underwent an attempted visceral hybrid procedure between January 2002 and April 2005. Twenty-two patients were elective, four were urgent (symptomatic), and three were emergent (true rupture). The median patient age was 74 years (range, 37 to 81 years). The aneurysms were Crawford type I in 3, type II in 18, type III in 7, and type IV in 1. Previous aortic surgery had been performed in 13 (45%) of 29 and included aortic valve and root replacement in 3, TAA repair in 1, type I repair in 1), type IV repair in 3, type B dissection in 2, infrarenal aneurysm in 5, and right common iliac aneurysm in 1. Severe preoperative comorbidity was present in 23 (80%) of 29: chronic renal impairment in 5, severe chronic obstructive pulmonary disease in 6, myocardial disease in 11 at New York Heart Association grade II (6) and grade III (5), and Marfan's syndrome in 6. Twenty-six patients (90%) had a completed procedure. In two patients, myocardial instability prevented completion of the procedure despite extensive preoperative cardiac assessment, and in one, poor flow in the true lumen of a chronic type B dissection prevented anastomosis of the revascularization grafts. Exclusion of the full thoracoabdominal aorta was achieved in all 26 completed procedures and extended to include the iliac arteries in four, with revascularization of coeliac in 26, superior mesenteric artery in 26, left renal artery in 21, and right renal artery in 21). RESULTS There was no paraplegia < or =30 days or during inpatient admission, and elective and urgent mortality was 13% (3/23). All of the patients with ruptured thoracoabdominal aneurysms died < or =30 days. Major complications included prolonged respiratory support (>5 days) in 9, inotropic support in 4, renal impairment requiring temporary support in 2 and not requiring support in 2, prolonged ileus in 2, resolved left hemispheric stroke in 1, and resection of an ischemic left colon in 1. Median blood loss was 3.9 liters (range, 1.2 to 13 liters). The median ischemia time was 15 minutes (range, 13 to 27 minutes) for the superior mesenteric and coeliac arteries and 15 minutes for the renal arteries (range, 13 to 21 minutes). The median hospital stay was 27 days (range, 16 to 84 days). Follow-up was a median of 8 months (range, 2 to 31 months), with 92 of 94 grafts patent. Six patients were found to have a type I endoleak. In four, this was a proximal leak, and stent extension in three reduced, but did not cure, the endoleak. One patient with a distal type I endoleak was successfully treated by embolization. Four type II endoleaks resolved without intervention, and one was treated by occlusion coiling of the origin of the left subclavian artery. A single late type III endoleak was found. CONCLUSION Early results of visceral hybrid stent-grafts for types I, II, and III thoracoabdominal aneurysms are encouraging, with no paraplegia in this particularly high-risk group of patients. These results have encouraged us to perform the new procedure, in preference to open surgery, in Crawford type I, II, and III thoracoabdominal aortic aneurysms.

Abstract
INTRODUCTION Dysphagia aortica is a swallowing condition caused by external compression of the esophagus due to aortic aneurysm or atherosclerotic changes affecting the aorta. The case report on this rare cause of dysphagia should contribute to better diagnosis of dysphagia aortica and swallowing difficulties in general. CASE REPORT A 63-year-old male patient was hospitalized duo to a four month history of intermittent swallowing difficulties. Chest radiography showed a widened mediastinum and an enlarged aortic arch. Rigid esophagus endoscopy was done in general endotracheal anesthesia. At 28 cm from the upper incisors, a difficulty in passing the endoscope appeared, revealing an external compression as a probable cause, since the whole esophagus had no intraluminal pathological changes. Contrast esophagography revealed an aortic aneurysm. The esophagus had a normal lumen width, wall tension and elasticity, and smooth contours. After cardiovascular examination and magnetic resonance imaging, a giant aneurysm of the aortic arch was diagnosed. DISCUSSION Patients with dysphagia aortica as well as patients with any other swallowing difficulties should be managed by multidisciplinary "dysphagia team". The team should include an otorhinolaryngologist, neurologist, radiologist, gastroenterologist, surgeon, dietitian, speech and language therapist and specially trained nurses. CONCLUSION Aneurysm of the thoracic aorta is a very rare cause of dysphagia. Mild to moderate symptoms can be in great disproportion with the severe condition which causes them.

Abstract
OBJECTIVE To analyse the fate of a visceral aortic patch (VAP) in patients that underwent thoracoabdominal aortic aneurysm (TAAA) repair. METHODS We reviewed 204 consecutive patients (158 M, 46 F) treated for TAAA between 1988 and 2004. We performed VAP in 182 cases. Among the 149 survivors at 6 months, we followed 138 cases, mean follow-up 7 years (range 0.6-16 years). The mean graft diameter we used was 29mm (range 24-34mm) from 1988 to 1999 (83 patients), and 21.7mm (range 16-24mm) from 2000 to 2003 (55 patients). In 23% of cases we performed a separate bypass to the left renal artery. RESULTS We observed 16 (12%) VAP dilatations (<5cm), 6 (4%) VAP aneurysms (>5cm) and one VAP pseudoaneurysm, at a mean time of 6 years after atherosclerotic TAAA was atherosclerotic repair. There were no VAP dilatations/aneurysms in the group of patients with separate left renal revascularization. Five VAP aneurysms were treated electively. In four cases the operation was performed with thoracophrenolaparotomy, in one case with a bilateral subcostal laparotomy. In all cases the visceral aorta was re-grafted. Reimplantation of a single undersized VAP was performed in one case, separate revascularization of visceral arteries was performed in the other four cases. Selective intraoperative hypothermic perfusion of visceral and renal arteries was used in all the patients. There was 1 perioperative death; 2 patients with preoperative renal failure required dialysis. The last VAP aneurysm has remained asymptomatic and stable at annual CT surveillance. The VAP pseudoaneurysm was successfully treated with an emergency thoracophrenolaparotomy and refashioning the left side suture line. CONCLUSIONS Aneurysm of VAP is not uncommon in the patients operated on using larger grafts with a single VAP that includes the LRA (7.4%, 5/67 cases). Its treatment carries significant morbidity and mortality.
