目的探讨胰周动脉瘤破裂出血的诊治。方法回顾3例胰周动脉瘤破裂出血患者的诊治过程，并结合相关文献进行分析。 结果3例患者胰周动脉瘤破裂出血并失血性休克，其中1例术前经CT检查获得诊断，2例术前未能诊断。2例经手术止血治愈，分别随访1年和1年2个月，未见复发及相关并发症; 1例经抢救无效死亡。结论胰周动脉瘤破裂出血病情发展迅速，术前诊断困难，尽快液体复苏及积极手术探查止血是挽救生命的关键。
ObjectiveTo investigate the improvement of visceral arterial blood supply after thoracic endovascular aortic repair (TEVAR) for patients with Stanford type B aortic dissection (AD). MethodsWe retrospectively analyzed clinical data of 35 patients with Stanford type B AD undergoing TEVAR in Mianyang Central Hospital from January 2013 to March 2014. There were 30 male and 5 female patients with their age of 45-82(62.5±10.0) years. Among the 140 main visceral arteries (celiac artery, superior mesenteric artery, left and right renal arteries) of the 35 patients, blood supply of 79 arteries were compromised, including 36 arteries with stenosis and blood supply via the true lumen, 18 arteries with blood supply via both true and false lumen, 18 arteries with blood supply via the false lumen, and 7 arteries without blood supply. Improvement of blood supply of main visceral arteries was analyzed. ResultsAll the operations were successfully performed without in-hospital death. Operation time was 97.8 (68-147) minutes, length of ICU stay was 12-34 h, and length of hospital stay was 10-21 days. None of the patients had cerebral infarction, acute renal failure, AD rupture or stent migration after TEVAR. Blood supply of the compromised visceral arteries showed improvement in various degrees. ConclusionFor the treatment of Stanford type B AD, TEVAR can not only successfully block the rupture of AD, but also improve blood supply of main visceral arteries, avoid or reduce the complications resulting from compromised visceral arterial blood supply and visceral ischemia.
ObjectiveTo investigate treatment methods and effect of endovascular interventional therapy for visceral artery aneurysms.MethodsThe clinical data of 32 patients with visceral artery aneurysms, who were treated in the No. 960 Hospital of PLA from February 2011 to April 2018, were retrospectively analyzed. It was proveded by the CT or digital subtraction angiography before the interventional therapy. The implantation of covered stent, coil embolization together with stent implantation, double stents placement or pure coil embolization were performed. The postoperative antithrombotic therapy was adopted in the patients accepted the stent implantation. The CT angiography was performed on the month of 1, 6, 12, 24 or the patient was uncomfortable after the treatment to evaluate the obstruction condition of the aneurysms, stent blood flow, and branches arteries, etc..ResultsThe success rate of the endovascular interventional therapy was 100%. In the 11 patients underwent the implantation of covered stent, the postoperative angiography showed that the stent lumen was patent and the aneurysm was not visualized. In the 9 patients underwent the coil embolization together with stent implantation and 3 patients underwent the double stents placement, the postoperative angiography results of the aneurysm showed that it was faintly visualized and the branch arteries were not involved. In the 9 patients underwent the pure coil embolization, the postoperative angiography showed that the aneurysm was not visualized. No perioperative mortality or procedure related complications occurred. No case was lost during the follow-up of a median period of 25.5 (6–48) months. During the follow-up, one patient developed the mild abdominal pain in one month, which disappeared after the symptomatic medication management. Except for 1 patient developed the mild stent stenosis (<30%) on the 12th month after the procedure, the stent and the branch arteries of the other patients were completely patent, and no aneurysms recurred.ConclusionFor treatment of visceral artery aneurysms, endovascular interventional therapy is safe and effective and shows an excellent short-term and mid-term effects.
