A 15-Year Single-Center Experience of Endovascular Repair for Elective and

Details
Journal Article 2016
  • Resource Description: PURPOSE: To evaluate the differences in technical outcomes and secondary interventions between elective endovascular aneurysm repair (el-EVAR) procedures and those for ruptured aneurysms (r-EVAR). RESULTS: At baseline, r-EVAR patients had larger aneurysms on average (p<0.001) compared to el-EVAR patients. Technical success was comparable (p=0.052), but there were more type Ia endoleaks at completion angiography in the r-EVAR group (p=0.038). As anticipated, more patients died in the first month in the r-EVAR group (18.9% vs 2.2% el-EVAR, p<0.001). At 5 years, there was an overall survival of 65.1% for the el-EVAR patients vs 48.1% in the r-EVAR group (p<0.001). The freedom from AAA-related mortality was 95.7% for el-EVAR and 71.0% for r-EVAR (p<0.001). Five-year freedom from type I/III endoleaks was significantly lower in the r-EVAR group (78.7% vs 90.0%, p=0.003). Five-year freedom from secondary intervention estimates were not significantly different (el-EVAR 84.2% vs r-EVAR 78.2%, p=0.064). CONCLUSION: Within our cohort of primary EVAR patients, r-EVAR cases showed comparable stent-graft-related technical outcome. Although there was a higher incidence of type Ia endoleaks on completion angiography in the r-EVAR group, the overall secondary intervention rate was comparable to el-EVAR.

A Comprehensive Review of In Situ Fenestration of Aortic Endografts

Details
Journal Article 2016
  • Resource Description: OBJECTIVE: Despite technical advances of fenestrated and branched endografts, endovascular exclusion of aneurysms involving renal, visceral, and/or supra-aortic branches remains a challenge. In situ fenestration (ISF) of standard endografts represents another endovascular means to maintain perfusion to such branches. This study aimed to review current indications, technical descriptions, and results of ISF. RESULTS: Most experimental papers evaluated ISF feasibility and assessed the consequences of ISF on graft fabric. Regarding clinical papers, 73 ISF procedures have been attempted in 58 patients, including 26 (45%) emergent and three (5%) bailout cases. Sixty-five (89%) ISF were located at the level of the arch, and eight (11%) in the abdominal aorta. Graft perforation was performed by physical, mechanical, or unspecified means in 33 (45%), 38 (52%), and two vessels (3%), respectively. ISF was technically successful in 68/73 (93%) arteries. At 30 days, two (3.4%) patients died in the setting of an aorto-bronchial fistula and an aorto-oesophageal fistula, respectively. No post-operative death, major complication, or endoleak was described as secondary to the ISF procedure. With follow-up between 0 and 72 months, four (6.9%) late deaths were noted, unrelated to the aorta. One (1.7%) LSA stent was stenosed without symptoms. CONCLUSIONS: Although there may be publication bias, multiple techniques were described to perform ISF with satisfactory short-term results. Long-term data remain scarce. Aortic endograft ISF is an off-label procedure that should not be used outside emergent bailout techniques

A multicenter 12-month experience with a new iliac side-branched device for revascularization of hypogastric arteries

Details
Journal Article 2016
  • Resource Description: OBJECTIVE: The aim of this study was to investigate the 1-year safety and efficacy of a new iliac side-branched device (IBD) for revascularization of the hypogastric arteries. RESULTS: Between January 2012 and January 2015, a total of 70 patients (69 men [98.6%]) with a median age of 74 years (range, 51-87 years) were consecutively treated; 66 patients had aneurysmatic disease of the iliac arteries, 2 patients had a para-anastomotic aneurysm after aortobi-iliac reconstruction, and another 2 patients had a type Ib endoleak after endovascular aneurysm repair. A total of 82 IIAs were revascularized, 12 bilaterally. Technical success was achieved in 100% (82/82) of the revascularized IIAs. All IBDs were patent at the end of the procedure. No instances of myocardial infarction, stroke, conversion to open repair, mesenteric or spinal cord infarction, or buttock necrosis were observed. There was one perioperative death (1.4%) in a 70-year-old patient with intraoperative gastrointestinal bleeding leading to multiple organ failure, which resulted in the patient's death on the fifth postoperative day. Within 30 days, one symptomatic occlusion of a treated common iliac artery (CIA) was observed. In two other patients, an asymptomatic kinking of the CIA segment of the IBD was revealed in the predischarge follow-up duplex ultrasound examination and corrected with relining. Median follow-up was 12 months (range, 6-16 months). One patient was lost during the follow-up period. Survival at 1 year was 98.5% with all IIAs rema

A multicenter experience with infected abdominal aortic endograft explantation

Details
Journal Article 2017
  • Resource Description: OBJECTIVE: Endovascular aneurysm repair (EVAR) is widely used with excellent results, but its infectious complications can be devastating. In this paper, we report a multicenter experience with infected EVAR, symptoms, and options for explantation and their outcome. RESULTS: Thirty-three patients with an infected aortic endograft were identified. In this group, at index EVAR, six patients (18%) presented with a groin or psoas infection and six patients (18%) presented with a general infection, including catheter-related infection (n = 3), prostatitis (n = 1), cholecystitis (n = 1), and pneumonia (n = 1). After index EVAR, eight patients underwent successful inferior mesenteric artery embolization for a type II endoleak within 6 months of index EVAR and one patient received an additional stent for a type Ib endoleak 1 week after index EVAR. Median time between the first clinical signs of infection and endograft explantation was 30 days (range, 1 day to 2.2 years). The most common presenting characteristics were pain and fever in 21 patients (64%) and fever alone in 8 patients (24%). Suprarenal fixation was present in 20 of 33 endografts (60%). All patients underwent endograft explantation, with bowel resection in 12 patients (36%) presenting with an endograft-enteric fistula. Methods of reconstruction were graft placement in situ in 30 patients and extra-anatomic bypass in 3 patients. In situ conduits were aortic cryopreserved allografts in 23, polyester silver graft in 5, and autogenous femoral vein in 2. Microbiology specimens obtained from the endograft and the aneurysm were positive in 24 patients (74%). Gram-positive organisms were the most commonly found
