Retrograde superficial femoral artery recanalization through a deep femoral collateral: A transradial approach.

A novel endovascular approach using retrograde access to an occluded superficial femoral artery via collaterals of the deep femoral artery is described. Owing to a prior aortobifemoral bypass, transradial access was used.

Autophagy: An Emerging Target for Developing Effective Analgesics.

Inadequate treatment of acute and chronic pain causes depression, anxiety, sleep disturbances, and increased mortality. Abuse and overdose of opioids and the side effects associated with chronic use of NSAID illustrate the need for development of safer and effective pain medication. Working toward this end, an tool based on an emergent intelligence analytical platform that examines interactions between protein networks was used to identify molecular mechanisms involved in regulating the body's response to painful stimuli and drug treatments.

Acute upper extremity ischemia and symptomatic popliteal artery aneurysm secondary to coronavirus disease 2019.

We report the cases of two patients with coronavirus disease 2019 (COVID-19). One patient had presented with acute right upper extremity ischemia (axillary artery thrombosis) and one patient with a symptomatic popliteal artery aneurysm (7.5 × 7.

Angiotensin-converting enzyme 2, coronavirus disease 2019, and abdominal aortic aneurysms.

Objective: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the etiologic agent of the current, world-wide coronavirus disease 2019 (COVID-19) pandemic. Angiotensin-converting enzyme 2 (ACE2) is the SARS-CoV-2 host entry receptor for cellular inoculation and target organ injury. We reviewed ACE2 expression and the role of ACE2-angiotensin 1-7-Mas receptor axis activity in abdominal aortic aneurysm (AAA) pathogenesis to identify potential COVID-19 influences on AAA disease pathogenesis.

Coil Embolization of Tributaries of Brachiocephalic Fistula is Effective in the Management of Vascular Steal.

Background: To determine if an aggressive approach to occlude all or majority of the tributaries of the cephalic vein is effective in eliminating signs and symptoms of vascular steal in patients with brachiocephalic fistula.

Methods: Retrospective chart review over a 15-month period of all patients managed with coil embolization of tributaries of brachiocephalic fistulae.

Results: A total of 19 patients (11 females, age 65 ± 9.
