Symptomatic Aortic Arch Floating Thrombus In A Patient With "Bovine Arch".

Bovine arch is an aortic arch variant in which the left common carotid artery and the brachiocephalic trunk share the same origin. Several vascular pathologies, as aneurysm, dissection or strokes have an increased prevalence in patients with this anatomic variant. We describe the first reported case of a young patient with a symptomatic aortic arch floating thrombus in association with a bovine arch.

Immunological Aspects Involved in the Degeneration of Cryopreserved Arterial Allografts.

Cryopreserved arterial allografts have remained an option in patients requiring distal revascularization or associated with vascular infection, in the absence of a valid autogenous saphenous vein. The objective of this study is to describe the different clinical, anatomopathological, and immunological findings related to vascular transplant rejection. In a prospective trial, 35 patients who underwent cryopreserved allogeneic arterial bypass were studied, including demographics and conduit patency.

Endovascular Treatment of a Traumatic Axillary Artery Rupture Using the Dual Bull's-Eye Technique.

Background: Our purpose is to report a case of an axillary artery rupture treated by endovascular means using the dual bull's-eye technique. An 83-year-old woman with multiple comorbidities was diagnosed with axillary artery rupture after the reduction of a shoulder dislocation.

Methods: An endovascular repair attempt was made, but, despite the use of a double approach (antegrade and retrograde), reconnecting both ends of the severed artery was deemed not possible.
