Balloon protection of the mesenteric-renal vessels during embolectomy of acute paravisceral aortic occlusion.

Acute thrombosis of the aorta is an uncommon, but potentially devastating, vascular emergency. The absence of pathognomonic signs or symptoms makes the diagnosis challenging and, often, time consuming. No optimal treatment has been established, with greater challenge present when the thrombus involves the mesenteric-renal vessels.

When Occipital Artery Biopsy is Preferred to Temporal Biopsy for Giant Cell Arteritis: A Step-By-Step Description of the Surgical Technique.

Giant cell arteritis is an autoimmune disease that affects large and medium blood vessels of the head and neck. Its prompt treatment is mandatory to avoid severe and permanent complications, such as blindness. Temporal artery biopsy is an important part of the diagnostic work-up, especially in those patients with cranial symptoms or in the elderly with a fever of unknown origin.

"Redo" 2D-3D Fusion Technique during Endovascular Redo Aortic Repair.

Purpose: The present study aims to describe a new 2D-3D fusion registration method in the case of endovascular redo aortic repair and compare the accuracy of the registration using the previously implanted devices vs. bones as landmarks.

Materials And Methods: This single-center study prospectively analyzed all the patients that underwent elective endovascular re-interventions using the Redo Fusion technique between January 2016 and December 2021 at the Vascular Surgery Unit of the Fondazione Policlinico Universitario A.
