Critical carotid artery stenosis involving a persistent primitive hypoglossal artery.

Persistent primitive hypoglossal artery (PPHA) is a rare internal carotid-vertebrobasilar anatomic variant. Awareness of this anomaly and its propensity for atherosclerotic disease is important to avoid misinterpretation of diagnostic studies and to allow appropriate interventional planning. As the predominant vascular supply to the anterior and posterior cerebral circulation, its luminal compromise can lead to devastating ischemic complications.

Outcomes and Durability of Endovascular Aneurysm Repair in Octogenarians.

Background: Endovascular aneurysm repair (EVAR) accounts for the majority of all abdominal aortic aneurysm (AAA) repairs in the United States. EVAR utilization in the aging population is increasing due to the minimally invasive nature of the procedure, the low associated perioperative morbidity, and early survival benefit over open repair. The objective of this study is to compare the outcomes of octogenarians after elective EVAR to their younger counterparts, a question that can be answered by a long-term, institutional data set.

Superior Lower Extremity Vein Graft Bypass Patency among Married Patients with Peripheral Artery Disease.

Background: Outcome disparities associated with lower extremity bypass (LEB) for peripheral artery disease (PAD) have been identified but are poorly understood. Marital status may affect outcomes through factors related to health risk behaviors, adherence, and access to care but has not been characterized as a predictor of surgical outcomes and is often omitted from administrative data sets. We evaluated associations between marital status and vein graft patency following LEB using multivariable models adjusting for established risk factors.

Gender-specific Differences in Great Saphenous Vein Conduit. A Link to Lower Extremity Bypass Outcomes Disparities?

Background: Inferior lower extremity bypass (LEB) outcomes have been reported among women with peripheral arterial disease (PAD), but the mechanisms responsible for this disparity are unknown. Great saphenous vein (GSV) is considered the conduit of choice for LEB; GSV diameter is associated with graft patency and therefore is often used as a criterion for suitability for use as bypass conduit. We hypothesized that gender-based differences in GSV may contribute to LEB outcomes disparities.

Results of surgical management of acute thromboembolic lower extremity ischemia.

Objective: Acute lower extremity ischemia secondary to arterial thromboembolism is a common problem. Contemporary data regarding this problem are sparse. This report examines a 10-year single-center experience and describes the surgical management and outcomes observed.
