目的:通过导管以胃十二指肠动脉为主,胃右动脉为副灌注治疗晚期胃窦癌的研究。材料与方法:采用Seldinger穿刺超选择灌注化疗药物术,对24例不能手术的晚期胃窦癌进行灌注抗癌药物67次。结果;介入膻注治疗后22例临床近期症状明显改善,进食量及体重均有不同程度的增加。钡餐及胃镜复查肿块缩小50%者13例(54.2%),缩小30%者7例(29.3%),1例肿块消失。结论:采用以胃十二指肠动脉为主,胃右动脉为副灌注化疗治疗晚期胃窦癌是一种值得探讨和尝试的有效方法。  相似文献

目的探讨胃十二指肠动脉的超声表现和探查方法及其在临床应用的意义。方法观察200例正常人的胃十二指肠动脉,注意其与肝总动脉的关系、毗邻关系、在胰腺内的走行、回声特点、内径正常值、超声所能探及的长度范围。50人进行了彩色多普勒探查。结果仰卧位、左侧卧位及饮水充盈胃窦三种方法联合应用,使胃十二指肠动脉的总显示率为97.5%(195/200),且图像清晰。胃十二指肠动脉起于肝总动脉,经门静脉的前方向下走行于胰腺包膜下或实质内,呈典型的动脉回声图像,内径值为(0.34±0.07)cm,超声所能探查的长度为(2.93±0.55)cm,血流速度(71±6)cm/s。结论多种体位和方法联合应用,以及耐心细致地扫查,胃十二指肠动脉的显示可以达到满意的效果,获得正常声像图。  相似文献

Pseudoaneurysms of the splanchnic arteries are rare causes of gastrointestinal bleeding. We report a case of a spontaneous gastroduodenal artery false aneurysm ruptured into the duodenum in a patient with hemophilia. The diagnosis was confirmed by spiral computed tomography and magnetic resonance angiography. The patient died from massive gastrointestinal bleeding.  相似文献

Eleven patients with massive duodenal hemorrhage were treated by emergent embolization. Bleeding originated from duodenal ulcer in three patients, from duodenal tumor in one, from ruptured pancreaticoduodenal artery pseudoaneurysm in three, and from ruptured gastroduodenal artery pseudoaneurysm in four. Complete hemostasis was obtained immediately after embolotherapy in all cases. Three of these patients died during the hospitalization period, one of whom from duodenal infarction and pancreas necrosis induced by embolization. In three patients with duodenal ulcer, complete hemostasis was obtained only by the gastroduodenal artery embolization with Gelfoam particles. Seven patients with pseudoaneurysms of the gastroduodenal artery or its branches required not only blockage of blood flow from the celiac artery but also the superior mesenteric artery for complete hemostasis. Therefore, in patients presenting with duodenal hemorrhage, the possibility of dual blood supply to the duodenum should be considered. Emergent embolization represents a useful alternative to surgery for massive duodenal hemorrhage, but it carries a risk of complications in patients with previous gastroduodenal surgery or significant visceral atherosclerosis.  相似文献
