Collateral artery pathways of the femoral and popliteal artery.

Background: The role of collateral artery circulation in the lower limb is under debate but clinically relevant, particularly when using covered stents for occlusive disease. Covered stents seem to outperform nitinol stents in extensive disease, but collaterals could be essential in case of acute thrombosis. In the present study, we describe the collateral pathways of the deep and superficial femoral artery (DFA, SFA) and the popliteal artery (PA), observed in human cadavers.

Longitudinal retention of anatomical knowledge in second-year medical students.

The Radboud University Medical Center has a problem-based, learner-oriented, horizontally, and vertically integrated medical curriculum. Anatomists and clinicians have noticed students' decreasing anatomical knowledge and the disability to apply knowledge in diagnostic reasoning and problem solving. In a longitudinal cohort, the retention of anatomical knowledge gained during the first year of medical school among second-year medical students was assessed.

Five-Year Outcome of Self-Expanding Covered Stents for Superficial Femoral Artery Occlusive Disease and an Analysis of Factors Predicting Failure.

Purpose: To investigate the 5-year outcome of patients treated with self-expanding covered stents for superficial femoral artery (SFA) occlusive disease and identify parameters that could predict loss of primary patency.

Methods: In a dual-center study, 315 consecutive patients (mean age 69.0±10.

Advancements in catheter-directed ultrasound-accelerated thrombolysis.

Purpose: To review all available literature on catheter-directed ultrasound-accelerated thrombolysis for peripheral artery occlusions, stroke, deep venous thrombosis, and pulmonary embolism.

Methods: A systematic literature search was performed, using MEDLINE, EMBASE and Cochrane databases. A total of 77 reports focusing on catheter-delivered ultrasound-accelerated thrombolysis were identified.
