Aneurysm presence at the anterior communicating artery bifurcation is associated with caliber tapering of the A1 segment.

J Neurosurg 2021 Oct 15:1-11. Epub 2021 Oct 15.

1Department of Neurosurgery, Tufts Medical Center and Tufts University School of Medicine, Boston, Massachusetts.

Objective: Vessel tapering results in blood flow acceleration at downstream bifurcations (firehose nozzle effect), induces hemodynamics predisposing to aneurysm initiation, and has been associated with middle cerebral artery (MCA) aneurysm presence and rupture status. The authors sought to determine if vessel caliber tapering is a generalizable predisposing factor by evaluating upstream A1 segment profiles in association with aneurysm presence in the anterior communicating artery (ACoA) complex, the most prevalent cerebral aneurysm location associated with a high rupture risk.

Methods: Three-dimensional rotational angiographic studies were analyzed for 68 patients with ACoA aneurysms, 37 nonaneurysmal contralaterals, and 53 healthy bilateral controls (211 samples total). Read More

Intentional Bilateral Renal Artery Coverage During Ruptured Endovascular Paraanastomotic Pseudoaneurysm Repair.

Ann Vasc Surg 2021 Oct 12. Epub 2021 Oct 12.

University of California, Irvine Medical Center, Division of Vascular and Endovascular Surgery, Department of Surgery, Orange, CA, USA. Electronic address:

The development of a paraanastomotic pseudoaneurysm is a serious complication after open prosthetic reconstruction of the aorta for occlusive or aneurysmal disease. Open repair of these lesions has previously been associated with high rates of morbidity and mortality. Endovascular repair may provide suitable treatment for proximal paraanastomotic aortic bypass graft pseudoaneurysms in patients who are poor candidates for open surgery. Read More
