BACKGROUND: Fenestrated (F-) endovascular aneurysm repair (EVAR)'s lack of widespread availability encouraged alternative strategies. Chimney graft (CG)-EVAR has spread when costs, manufacturing delays or anatomy preclude F-EVAR. Our objective was to evaluate CG-EVAR and F-EVAR's outcomes depending on the angulation of target renal arteries and hostility of iliac accesses to determine the potential impact of a choice made between the two techniques based upon preoperative anatomic criteria...

An 87-year-old woman with severe aortic stenosis underwent a transfemoral transcatheter aortic valve replacement (TAVR). Intraoperative transesophageal echocardiography demonstrated a well-seated valve with no paravalvular leak; however, a new acute type B aortic dissection was identified. Endografts were delivered through the TAVR sheath and deployed, effectively treating the dissection. The patient did well postoperatively, with imaging at 2 years demonstrating a well-functioning aortic valve and no migration or endoleak of the thoracic endografts...

BACKGROUND: Aortic arch disease is a challenging clinical problem, especially in high-risk patients, in whom open repair can have morbidity and mortality rates of 30% to 40% and 2% to 20%, respectively. Aortic arch chimney (AAC) stents used during thoracic endovascular aortic repair (TEVAR) are a less invasive treatment strategy than open repair, but the current literature is inconclusive about the role of this technology. The focus of this analysis is on our experience with TEVAR and AAC stents...

BACKGROUND: Interventions for aortic aneurysm sac growth have been reported across multiple time points after endovascular aortic aneurysm repair (EVAR). We report the long-term outcomes of patients after EVAR monitored with duplex ultrasound (DUS) imaging with respect to the need for and type of intervention after 5 years. METHODS: We report a series of patients who were monitored with DUS imaging for a minimum of 5 years after EVAR. DUS imaging was performed in an accredited noninvasive vascular laboratory, and computed tomography angiography was only performed for abnormal DUS findings...

BACKGROUND: With approval of on-label fenestrated (F-) endovascular aortic repair (EVAR), concerns regarding long-term patency and endoleaks (ELs) after chimney graft (CG)-EVAR were raised. To add supportive data on the value of this technique, we chose to report the midterm results of CG-EVAR in a single center with standardized methods and to compare them to F-EVAR. METHODS: A retrospective analysis of prospectively gathered data from January 2010 to January 2015 was conducted, and patients with excessive comorbidities for open repair treated by CG-EVAR or F-EVAR were included...

Patients undergoing endovascular repair (EVAR) of aortoiliac or iliac artery aneurysm may require sacrifice of one or both internal iliac arteries (IIAs). Until Food and Drug Administration-approved commercial grafts became available, endovascular IIA preservation was accomplished using the "sandwich" technique, but limited information is available regarding the results of this method. After obtaining institutional review board approval, we identified patients undergoing IIA preservation with the sandwich technique during EVAR at our institution...
