自发性栓塞导致外周动脉闭塞仍然是发病和肢体丧失的重要原因。准确定位和纠正栓塞源对于预防进一步发作、保持长期通畅和保肢至关重要。常见的栓塞源包括心内血栓或粘液瘤，动脉瘤内血栓或复杂的动脉粥样硬化斑块。不太常见的是在其他正常的主动脉中新生血栓，可能是由于先前的创伤、隐匿性动脉病和/或高凝状态。本文报告了三例外周或肠系膜栓塞，由内脏主动脉段内的大血栓引起，动脉粥样硬化或其他主动脉病变的证据很少。每例患者均采用直接手术入路行内脏主动脉血栓切除术。
Spontaneous embolization resulting in peripheral arterial occlusion remains a significant cause of morbidity and limb loss. Accurate localization and correction of the embolic source is paramount for the prevention of further episodes and for the preservation of long-term patency and limb salvage. Common well-recognized embolic sources include intracardiac thrombus or myxoma, and thrombus within arterial aneurysms or complex atherosclerotic plaques. Less common is thrombus arising de novo in an otherwise normal aorta, possibly as a result of prior trauma, occult arteriopathy, and/or hypercoagulability. Reported herein are three cases of peripheral or mesenteric embolization arising from large thrombi within the visceral aortic segment, with minimal evidence for atherosclerosis or other aortic pathology. Each patient was treated with visceral aortic thrombectomy using a direct surgical approach.
