[PMID: 37898457 DOI: 10.1016/j.avsg.2023.08.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 08/28/2023] [Accepted: 08/29/2023] [Indexed: 10/30/2023]
Abstract
BACKGROUND To perform a systematic review on contemporary outcomes of endovascular repair and open surgical repair (OSR) for the treatment of mycotic aortic aneurysm (MAA). METHODS A comprehensive literature search on the management of MAAs with endovascular repair or OSR was performed between January 1998 and January 2023. Patient demographics, early and late outcomes were analyzed with respect to treatment modality and MAA location. RESULTS Forty-eight articles were included, encompassing a total of 1,358 patients (75.8% male; mean age 66.9 years; 1,372 aneurysms) treated by open (49.8%) or endovascular (50.2%) repair. Salmonella spp., and Staphylococcus spp. were the most prevalent pathogens in Asian and European countries respectively. An increasing number of descending thoracic MAAs were managed by endovascular repair (27.9% vs. 12.8%). Early mortality rates for supra- and infra-renal MAAs managed by endovascular repair were lower than OSR (suprarenal 5.4% vs. 43.2%; infrarenal 1.8% vs. 16.7%). Overall, endovascular repair demonstrated lower intraoperative (1.0% vs. 1.8%) and early mortality (6.5% vs. 15.9) rates than OSR. However, endovascular repair was associated with higher late sepsis rate (5.7% vs. 0.9%) and reintervention rate (17.6% vs. 7.3%). Pooled survival rates at 1- and 5-year were similar between the 2 groups. CONCLUSIONS Current literature suggest that endovascular repair is an effective and safe alternative to OSR for descending thoracic, suprarenal, and infrarenal MAAs. However, endovascular repair is associated with higher risk of infection-related complications and reintervention during follow-up.

Treatment of infected thoracic aortic aneurysm with combined abscess debridement and stent-graft wrapping using pedicled latissimus dorsi muscle flaps after thoracic endovascular aortic repair. J Cardiothorac Surg 2023; 18:57. [PMID: 36732803 PMCID: PMC9896790 DOI: 10.1186/s13019-023-02155-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Accepted: 01/24/2023] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Open thoracic surgery (with infected lesion removal, prosthetic graft replacement, and pedicled tissue flap) has remained the main treatment for infected thoracic aortic aneurysms to date. Recent reports have highlighted good prognostic outcomes with thoracic endovascular aortic repair. However, thoracic endovascular aortic repair for infected thoracic aortic aneurysms is associated with an exacerbation of infection due to residual infected tissues. We discuss the control of refractory infections following endovascular treatment of infected thoracic aortic aneurysms. CASE PRESENTATION An 81-year-old man, with a history of insulin-dependent diabetes mellitus and pancreaticoduodenectomy, presented to our emergency department with a fever. Blood tests revealed a markedly elevated leukocyte count, and contrast-enhanced computed tomography suggested a descending thoracic aortic pseudoaneurysm. We diagnosed the patient with an infected descending thoracic aortic aneurysm, and performed urgent thoracic endovascular aortic repair; he was started on an intravenous antibiotic treatment. Postoperatively, blood tests revealed a decreased leukocyte count and the patient remained afebrile. However, computed tomography revealed temporal enlargement of the abscess cavity; therefore, an abscess debridement and stent graft wrapping with pedicled latissimus dorsi muscle flaps were performed, which successfully controlled the infection. Six weeks after abscess debridement, the patient was switched to an oral antibiotic therapy. There was no evidence of recurrence of infection 8 months after the surgery. CONCLUSIONS A combined abscess debridement and pedicled tissue flap approach is useful for patients with poor surgical tolerance in whom infection control is difficult after thoracic endovascular aortic repair for infected thoracic aortic aneurysms. Pedicled latissimus dorsi muscle flaps are useful when using the omentum for pedicled tissue flap is difficult.

Abstract
A man in his 80s undergoing chronic hemodialysis presented with a high fever. A 10-cm soft mass was palpable in his right buttock. Abdominal computed tomography and angiography showed an incomplete-type unilateral persistent sciatic artery aneurysm (PSAA) with gas patterns and a blood flow through the aneurysm. Incision drainage was performed after arterial embolization. Gram staining of the hematoma showed gram-positive cocci that had formed chains, thus leading to a diagnosis of an infected PSAA. Drainage by incision after arterial embolization was used as the therapeutic method of choice for a massive infected PSAA with a sustained blood flow in order to prevent sciatic nerve injury and bleeding associated with PSAA resection.

Abstract
Background Isolated mycotic internal iliac artery aneurysms are rare and management of these patients can be complex. Case summary We present a rare case of isolated mycotic right internal iliac artery aneurysm caused by Salmonella enteritides. This was managed in stages – with intravenous antibiotics, followed by endovascular stenting and embolization, and subsequent percutaneous drainage of the remnant collection. The patient had no perioperative complications, and has remained well at more than 18 months post-operatively with no evidence of stent infection. Conclusion A minimally-invasive approach combining endovascular aneurysm repair and percutaneous drainage is a viable option in the management of a mycotic internal iliac artery aneurysm.

Abstract
Background: Mycotic aneurysms (MAs) are relatively rare but life-threatening. Some recent reports have described the use of endovascular therapy for their treatment; however, this still is a controversial treatment, and a definite target population has not been determined. Methods: We performed surgery on 34 patients with MAs from March 2005 to March 2019. Twenty patients who underwent open surgery (OS) first comprised the OS group, and 14 patients who underwent endovascular therapy first comprised the stent-graft (SG) group. We analyzed between-group differences, long-term outcomes, and risk factors for death retrospectively. Patients in the OS group had a higher initial white blood cell count than those in the SG group (p = 0.047). The SG group had more patients with a low albumin concentration (≤2.0 mg/dL) than did the OS group (p = 0.026). Results: There were no significant differences in the operative mortality rates between the groups (p = 0.773). Additional procedures were required more often in the SG than the OS group (p = 0.0013). The overall survival rate as estimated by the Kaplan-Meier method was 88% at 1 month, 67% at 1 year, 57% at 3 years, and 45% at 10 years. In the univariable analysis, chronic obstructive pulmonary disease (COPD) was a risk factor for death (p = 0.003). Conclusions: Endovascular therapy for MAs produced reasonable outcomes when patient selection was based on the activity level, nutritional condition, and degree of inflammation. Endovascular therapy may become an option for patients with a low albumin concentration or COPD despite the fact that additional procedures may be needed.

EJVES Vasc Forum 2020; 49:45-47.

Abstract
Introduction Persistent sciatic artery is a rare vascular anomaly. The occurrence of infected persistent sciatic artery aneurysm (PSAA) is extremely rare. Report An 84 year old woman who was under observation for a massive thrombosed right PSAA since the age of 74 presented with severe pain in her right lower limb. The patient was diagnosed with the infected PSAA by computed tomography and laboratory test. The condition was treated with antibiotics as well as drainage and removal of the infected thrombus with a small incision. Subsequently, the patient's symptoms improved, and she was discharged ambulatory. Sixteen months after the surgery, her condition remained good, with no evidence of recurrent infection. Conclusion Extensive debridement requires a large muscle incision and carries with it a risk of sciatic nerve injury. However, a thrombosed aneurysm has little risk of haemorrhage. Therefore, drainage and removal of the thrombus via a small incision, which is less invasive, was considered effective for this infected thrombosed PSAA. Infected persistent sciatic artery aneurysm (PSAA) is extremely rare. Primary treatment is extensive resection of the PSAA and surrounding tissues. Extensive debridement requiring a large incision poses a risk of sciatic nerve injury. PSAA was treated by drainage and removal of the thrombus via a small incision.

Abstract
PURPOSE To demonstrate post-treatment computed tomography (CT) findings and outcomes of endovascular aortic repair (EVAR) for mycotic aortic aneurysm (MAA). MATERIALS AND METHODS Clinical data of patients with MAA who underwent EVAR from June 2010 to December 2017 were retrospectively reviewed. A total of 22 patients were included (19 men and 3 women). The periaortic features of the MAA regression after EVAR were graded and evaluated by follow-up CT. RESULTS The median follow-up was 36.5 months (range, 0.5-97 months.). The cumulative survival rate at 1 month, 6 months, 1 year, and 5 years was 95.5%, 86.4%, 81.6%, and 73.4%, respectively. The early and late infection-related complication (IRC) rate was 18.2% and 13.6%, respectively. One patient died within 1 month from severe acidosis and shock. Of the other patients, the median time to stable response of the MAA was 6 months (range, 3-36 months). Fourteen patients (66.7%) showed early response of the MAA, while 7 patients (33.3%) showed delayed response. A significant association was observed between delayed response and late IRCs (P = .026). CONCLUSIONS The post-EVAR periaortic features on follow-up CT aid in monitoring the treatment response of the MAA. Early response of the MAA was associated with a low rate of late IRCs and might aid in adjusting the antibiotic duration after the patient has achieved complete or nearly complete regression of the MAA.

Abstract
INTRODUCTION: Although endovascular therapy is becoming an alternative to open surgical repair of splenic artery aneurysms (SAAs), reports on the use of stent grafts for SAA repair are limited. We present our experience of endovascular therapy using a stent graft for the treatment of an SAA that had ruptured into the gastric lumen. We also reviewed 18 cases of stent graft repair for SAAs, including the present case. CASE REPORT: A 43-year-old man was admitted due to hematemesis. Endoscopic examination and contrast-enhanced computed tomography (CT) revealed a dissecting SAA that had ruptured into the stomach. Two 10 × 100 mm Viabahn (W.L. Gore, Flagstaff, Arizona) stent grafts were used to exclude the aneurysm. No complications occurred during the procedure. Although postoperative CT showed complete exclusion of the aneurysm, endoscopic examination showed a discharge of purulent matter from the aneurysm. Therefore, surgical debridement and omental implantation were added to avoid stent graft infection. Follow-up CT obtained 1 year later showed the residual aneurysm almost disappeared without any evidence of infection. LITERATURE REVIEW: A literature search in the PubMed database returned 17 cases with sufficient data. Review of these cases, together with the present case, revealed a 100% technical success rate, 11% splenic infarction rate, 94% graft patency rate, and 0% reintervention rate. CONCLUSION: Endovascular repair of SAAs using stent grafts appears to be safe and effective. In terms of preserving the blood flow and avoiding splenic infarction, it may be superior to coil embolization. Even in a case with aneurysm infection, stent graft repair may be an acceptable method to minimize invasion of concomitant surgical intervention.
