Prophylactic Ligature of AV Fistula Prevents High Output Heart Failure after Kidney Transplantation.

Background: Arteriovenous (AV) fistulas are considered the gold standard for ensuring safe and long-term vascular access in patients with haemodialysis-dependent end-stage renal disease. However, previous studies demonstrated that high-flow AV fistulas might add additional cardiovascular burden in the post-transplant setting, leading to frequent fistula closure in this population. Currently, there is no consensus regarding management of high-flow fistulas in post-transplant patients with stable kidney function.

Iatrogenic Cardiac Tamponade During Endovascular Aortic and Mesenteric Stent Grafting: A Case Report.

The authors report a case of left ventricular perforation and cardiac tamponade in a patient undergoing endovascular aortic and mesenteric stent grafting. During the procedure, the anesthetist noticed a sudden increase in central venous pressure and a decrease in blood pressure. Cardiac tamponade was suspected and confirmed by transesophageal echocardiography.

Segmental disruption of the internal elastic lamina as a potential pathogenetic mechanism of a true posttraumatic femoral artery aneurysm, years after single blunt trauma.

We present an unusual case of a true posttraumatic aneurysm of the superficial femoral artery (SFAA) 7 years after a motorcycle accident including blunt trauma to the thigh. Surgical reconstruction was accomplished without any complications by aneurysm resection and interposition of an autologous reversed saphenous vein. Histopathological examination revealed a true aneurysm with segmental disruption and fragmentation of the internal elastic lamina (IEL) in van Gieson's stain.

Phosphocreatine kinetics in the calf muscle of patients with bilateral symptomatic peripheral arterial disease during exhaustive incremental exercise.

Purpose: To investigate the relationship between the atherosclerotic lesion load determined on magnetic resonance angiography (MRA) and phosphocreatine (PCr) kinetics during incremental, exhaustive calf exercise in patients with bilateral, symptomatic peripheral arterial disease (PAD).

Procedures: Using a 1.5 Tesla MR scanner, 26 patients with bilateral symptomatic PAD and 24 healthy male controls underwent serial phosphorus-31 MR spectroscopy (31P MRS) during incremental exercise at 2, 3, 4, and 5 Watts.

Peripheral ischemia caused by paradoxical embolization: an underestimated problem?

Although a patent foramen ovale (PFO) is often found in younger patients with transient ischemic attacks or stroke, paradoxical embolization through PFO is rarely considered as a cause of acute limb ischemia. We report a single-center experience of 5 consecutive patients with limb-threatening ischemia due to paradoxical embolization within a one-year period. All patients were treated by catheter thrombectomy and long-term oral anticoagulation after surgery.

Subtotal tongue necrosis in delayed diagnosed giant-cell arteritis: a case report.

Giant-cell arteritis (GCA) is a chronic systemic vasculitis of large- and medium-sized vessels, mainly affecting elderly patients. Headache, vision impairment, jaw claudication, and scalp tenderness are common symptoms. However, diagnosis can be difficult because GCA can affect almost every vascular pathway and lead to a variety of possible manifestations.
