A Rare Case of Bilateral Posterior Tibial Artery Aneurysm Presenting as Unilateral Acute Limb Ischemia.

True aneurysms of the tibial arteries are extremely rare. Of the few previously described tibial artery aneurysms, there are scant reports of isolated true aneurysms of the posterior tibial artery (PTA). In this report, we describe the second documented case of bilateral true PTA aneurysms.

Predilation technique with balloon angioplasty to facilitate percutaneous groin access of large size sheath through scar tissue.

Purpose Percutaneous remote access for endovascular aortic repair is an advantageous alternative to open access. Previous surgery in the femoral region and the presence of synthetic vascular grafts in the femoral/iliac arteries represent major limitations to percutaneous remote access. The aim of this study was to evaluate an original technique used for enabling percutaneous remote access for thoracic or abdominal endovascular aortic repair in patients with scar tissue and/or a vascular graft in the groin.

Age of transfused red cells and early outcomes after cardiac surgery.

Background: Red blood cells (RBC) undergo many changes during storage. Such changes are associated with reduced oxygen-carrying capacity and transfusion-related inflammatory reactions. The clinical significance of these changes in the cardiac surgical setting is unclear.
