UNLABELLED Carotid endarterectomy (CEA) is a surgical intervention that aims to reduce neurological symptoms in carotid atherosclerosis and prevent brain damage and subsequent permanent neurological deficit. AIM To study the major risk factors, surgical techniques, applied diagnostic methods and perioperative complications occurred in patients undergoing(More)
Extracranial carotid artery aneurysms are unusually rare. Their aetiology and clinical picture have significant meaning for their recognition, with the majority involving the common carotid artery--ACC. Approximately one third of these lesions are confined to the ICA, with an equal distribution between the proximal, middle, and distal segments. Nonoperated(More)
The question addressed was whether the use of sympathectomy was of benefit in non-revascularisable critical leg ischaemia. Altogether 387 papers were found, of which 13 represented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results, and study(More)
Despite the increased volume of patients undergoing selective reconstruction on the occasion of abdominal aortic aneurysms (AAA) in the last decades, the number of patients with rupture of abdominal aortic aneurysms (RAAA) is not significantly decreased. RAAA is catastrophic and life-threatening condition. It remains a challenge to every practitioner. To(More)

The standart anatomy textbooks indicate, as a rule that the lumbar sympathetic trunk contains four or five ganglia. The overall anatomic denervation is important for achievement of an adequate sympathectomy(More)
Aneurysms of the splenic artery account for about 60% of all aneurysms of visceral arteries. Most of them are asymptomatic until rupture and are discovered accidentally, usually after an imaging study. The treatment is surgical or endovascular depending on the type, location and size. We present a case of a patient with an asymptomatic, accidentally found(More)
