Abstract:
Abstract:Objective：To explore the method of endovascular therapy for complicated aortic dissections. Methods： The clinical data of 25 patients with complicated aortic dissections were analysed retrospectively. Results： The patients′ ages ranged from 31-72 years with a mean of 50.2 years. Among the 25 cases, 6 cases had severe ischemia of mesenteric artery, 5 cases had renal artery ischemia, 4 cases had severe ischemia of both legs, 3 cases had renal arteries ischemia combined with superior mesenteric artery ischemia, 2 had complicated aortic dissection combined with AAA, and in 5 cases the true aortic lumen was totally compressed by the false aneurysmal lumen. All patients underwent endovascular therapy, and the instant technique was successfully performed in all patients. Endoleak occurred in 3 cases after the stent-graft deployment, it stopped spontaneously in 2 of them 7 days later, and 1 case with endoleak waiting for treatment. In the other 22 patients, angiography after the operation showed that all the diseased area were sealed completely, and the viscera arterial blood supply was restored mainly via the true lumen. All the patients were cured and discharged. Conclusions：In the management of complicated aortic dissections, endoluminal technique is simple, less traumatic, safe and has less complications as compared to the traditional operation. Improvement of the endoluminal technique is essential for successful treatment of these complicated cases.
