Acute Nonruptured Expansion of Extracranial Carotid Artery Aneurysm. An Infrequent Clinical Presentation.

The extracranial carotid artery aneurysms are a rare disease, representing a low percentage of peripheral aneurysms (0.4-4%). Their main symptoms are derived from cerebral events and local compression, with rupture being rare.

Neutrophil-lymphocyte ratio as a link between complex pedal ulcers and poor clinical results after infrainguinal surgical revascularization.

Background: Our aim was to evaluate the influence of preoperative neutrophil-lymphocyte ratio (NLR) on patency and clinical results after infrainguinal surgical revascularization for chronic limb ischemia.

Methods: Retrospective analysis of 150 infrainguinal autologous bypasses performed to infragenicular popliteal artery or tibial vessels in 140 (93%) patients with chronic limb-threatening ischemia (CLTI) and in 10 (7%) with disabling claudication. NLR was calculated using blood samples obtained 24 hours preoperatively.
