PURPOSE: To report the outcomes of fenestrated endovascular aneurysm repair (FEVAR) and compare early and midterm results in relation to stent-graft complexity. METHODS: Between August 2006 and December 2014, 141 consecutive patients (mean age 72±7.6 years, range 50-89; 120 men) were treated electively with FEVAR for short-neck, juxtarenal, or suprarenal aortic aneurysms. Forty-five patients treated with stent-grafts featuring renal-only fenestrations were assigned to group A, while 96 patients receiving additional fenestrations for the superior mesenteric and/or celiac arteries were assigned to group B...

We report a successful treatment of thoracic arch aneurysm using a combination of hybrid approach and a customized stent graft in a frail patient with challenging anatomy and concomitant large retrosternal goiter. The patient is an 82-year-old lady with multiple comorbidities who presented to her general practitioner for anorexia and significant weight loss. She was incidentally found to have a 6.6 cm saccular distal aortic arch aneurysm, a 5.5 cm infrarenal abdominal aortic aneurysm, and a large goiter adjacent to the left common carotid artery with retrosternal extension...

Five cases of ductal lesions with various anatomies have been successfully treated by thoracic endovascular aortic replacement in recent years; 4 using mainly fenestrated stent-grafts, and one using a non-fenestrated stent-graft. Considering the invasive nature of open surgery and the anatomical limitations of the catheter technique for occluding a patent ductus in many adult cases, thoracic endovascular aortic replacement should be the first option because of its broad applicability for ductal lesions.

Hostile infrarenal aortic neck anatomy presents a challenge for the endovascular treatment of abdominal aortic aneurysm. Open surgical repair has been seen as the gold standard treatment for juxtarenal abdominal aortic aneurysm; however, endovascular techniques are now becoming more prevalent, particularly in patients deemed high risk for morbidity and mortality with open repair. The morphology of an aneurysm is a determinant of long-term outcomes, and short aneurysm necks are associated with poorer outcomes and a higher rate of secondary reinterventions...

Juxtarenal aortic aneurysms (JAAs) have been conventionally treated using open repair with excellent results. Recent approval of fenestrated stent grafts by the United States Food and Drug Administration has given patients with JAAs an alternative for repair. However, most of these procedures are still performed under general anesthesia, making some surgeons reluctant to offer repair to a subset of patients deemed too high risk for general anesthesia. We present three patients with JAAs at high surgical risk, including one patient with a ruptured aneurysm, who were successfully treated using a fenestrated stent graft under regional anesthesia...

PURPOSE: The study purpose was to review the outcomes of patients treated for thoracoabdominal aortic aneurysms using endovascular repair with fenestrated and branched stent-grafts in a single center. METHODS: We reviewed the clinical data of the first 185 consecutive patients (134 male; mean age, 75 ± 7 years) treated for thoracoabdominal aortic aneurysms using fenestrated and branched stent-grafts. Graft design evolved from physician-modified endografts (2007-2013) to off-the-shelf or patient-specific manufactured devices in patients enrolled in a prospective physician-sponsored investigational device exemption protocol (NCT 1937949 and 2089607)...

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. METHOD: A review of the English language literature was performed in Medline databases, Cochrane Database, Web of Science, and Scopus using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines...

Endovascular repair of pararenal and thoracoabdominal aortic aneurysms with fenestrated and branched stent grafts has been increasingly utilized with high technical success and low morbidity and mortality. Freedom from branch-related events has been reported at 89% in 5 years, including any branch-related endoleak, stenosis, kink, disconnection, or occlusion. Patient-specific stent grafts have the advantage of fitting patients' anatomy, but require a 6- to 8-week period for customization. Off-the-shelf stent grafts have been developed based on a relative predictability of renal-mesenteric vessels...

The endovascular treatment of juxtarenal abdominal aortic aneurysm (AAA) can be performed by either a standard endovascular stent graft with additional snorkle grafts to aorta branches (snorkel endovascular aneurysm repair) or implantation of a fenestrated stent graft (fenestrated endovascular aneurysm repair). While many vascular surgeons consider snorkel endovascular aneurysm repair and fenestrated endovascular aneurysm repair to be competing techniques or alternate strategies, published procedural outcomes suggest more complementary roles...

New developments in infrarenal abdominal aortic aneurysm stent-graft devices have made more patients eligible for endovascular aneurysm repair (EVAR). Recent US Food and Drug Administration approval for fenestrated endograft repair and impending approval for iliac branch devices extend the proximal and distal landing zones. Better deployment systems allow for partial deployment of endografts to facilitate repositioning, and more flexible designs allow for treatment of angulated infrarenal aneurysm necks and tortuous iliac arteries...

BACKGROUND: No reliable comparative data exist between open repair (OR) and endovascular aneurysm repair (EVAR) for mycotic abdominal aortic aneurysms (MAAAs). This nationwide study assessed outcomes after OR and EVAR for MAAA in a population-based cohort. METHODS: All patients treated for MAAAs in Sweden between 1994 and 2014 were identified in the Swedish vascular registry. The primary aim was to assess survival after MAAA with OR and EVAR. Secondary aims were analyses of the rate of recurrent infections and reoperations, and time trends in surgical treatment...

BACKGROUND: Off-label parallel endografting (PE) has been increasingly criticized in favor of on-label custom fenestrated endografts. There remain limited direct comparisons, however, between concurrent patient populations treated by similarly experienced operators. Hence, we seek to evaluate the relative efficacy of the two techniques in treating complex aortic pathology. METHODS: All patients treated by PE or with Cook Zenith Fenestrated (Zfen) devices from January 2010 to June 2015 were reviewed, excluding those treated for rupture...
