Mid-Term Results of Treating Kommerell's Diverticulum and Aberrant Subclavian Artery Anomalies Using a Patient-Centered Team Approach.

Introduction: The management of Kommerell's Diverticulum (KD) has evolved from open surgical resection and graft replacement of the aorta, to endovascular repair in asymptomatic patients due to its recognized possible sequelae - aortic rupture and dissection. Despite these technical advances, standard indications for intervention and treatment algorithms remain unclear. We will present our single-center experience in the treatment of KD, supporting a multidisciplinary endovascular-first approach.

Carotid-Axillary Bypass as an Alternative to Carotid-Subclavian Bypass Following Coverage of Left Subclavian Artery During TEVAR.

Introduction: Thoracic Endovascular Aortic Repair (TEVAR) has become the procedure of choice for pathology involving the descending thoracic aorta since its approval by the FDA in 2005. Left subclavian artery (LSA) coverage is commonly required to facilitate an adequate proximal landing zone for the endograft. The traditional revascularization procedure of choice is carotid-subclavian bypass, however recent studies report complication rates as high as 29%-specifically phrenic nerve palsy in 25% of patients undergoing this procedure.

A novel technique using long segment patch angioplasty maturation to increase the maturation rate of arteriovenous fistulas.

Objective: Given the superior patency of arteriovenous fistulas (AVFs) and the decreased risk of infection compared with arteriovenous grafts, the Kidney Disease Outcomes Quality Initiative guidelines have recommended the fistula-first approach. However, ∼20% to 60% of all fistulas will fail to mature. We have described our experience with a novel technique using bovine pericardial patch angioplasty to increase the rate of AVF maturation.
