目的：探讨DSA诊断小肠血管畸形的价值。方法：本文分析21例小肠血管畸形患者的临床及DSA特征，其中男性14例，女性7例，所有患者均行肠系膜上、下动脉造影。结果：临床特征：①急性消化道出血为主症状；②常规检查一般为阴性；③血红蛋白含量短期内降至4～6 g/mL。DSA特征：①动静脉瘘；②局部肠壁染色增浓；③局部血管异常增多，结构紊乱。其中12例进行了动脉导丝栓塞，2例栓塞后出血，进行外科手术切除。结论：DSA是诊断血管畸形所致小肠出血的最有效的方法，动脉导丝栓塞是安全，有效的治疗方法，同时为外科手术切除提供的正确部位。
目的:探讨鼻咽纤维血管瘤术前栓塞的应用价值。方法:17例鼻咽纤维血管瘤患者,单纯手术摘除10例,术前3天进行数字减影血管造影(DSA)检查及血管内栓塞术7例。结果:7例术前栓塞组术中出血200～700mL,平均430mL;输血0～550mL;10例单纯手术组出血550～1430mL,平均1200mL,输血350～1200mL。术前栓塞组出血量和输血量较单纯手术组显著减少。结论:术前瘤体栓塞治疗鼻咽纤维血管瘤是安全有效、理想的术前辅助治疗手段。
摘要:目的:探讨腹腔镜胆囊切除术(laparoscopic cholecystectomy, LC)后发生严重并发症的原因、治疗措施和经验教训。方法:分析 2007 年 8 月至2009 年 4月期间华西医院胆道外科收治的LC术后发生严重并发症的7例患者的临床资料。结果:2例继发性胆总管结石合并化脓性胆管炎患者,采用内镜下十二指肠乳头切开(endoscopic sphincterotomy, EST)取出结石;3例胆道损伤患者,均进行肝门胆管成形和肝总管空肠吻合术;1例绞窄性肠梗阻患者,切除坏死空肠管后,行空肠对端吻合术;以上6例患者均顺利出院,随访8～20个月,均生活良好。1例患者LC术后发生肺动脉栓塞,积极抢救后因呼吸衰竭而死亡。结论:术中仔细轻柔的操作以及辩清肝总管、胆总管与胆囊管的三者关系是预防LC术后发生严重并发症的关键。合理可行的治疗措施是提高发生并发症的患者生活质量的保障。LC术时,胆道外科医生思想上要高度重视,不可盲目追求速度,必要时及时中转开腹。Abstract: Objective: To investigate the causes and therapeutic measures and the experience and lesson of sever complications after laparoscopic cholecystectomy (LC). Methods:Clinical data of 7 patients with severe complications after LC from August 2007 to April 2009 were analyzed retrospectively. The clinical data was got from biliary department of West China Hospital. Results: Two cases of secondary common bile duct stone with acute suppurative cholangitis got cured by endoscopic sphincterotomy. Three cases of severe bile duct injury after LC had stricture of the hilar bile duct, and all of the cases were performed RouxenY hepaticojejunostomy with the diameter of stoma 2.03.0 centimeters. One case of strangulating intestinal obstruction was cured through jejunum endtoend anastomosis after cutting off the necrotic jejunum. All of the above 6 patients recovered well. Following up for 820 months, all lived well. One patient got pulmonary embolism after LC and dead of respiratory failure after active rescue. Conclusion: Carefully making operation and distinguishing the relationship of hepatic bile duct and common bile duct and the duct of gallbladder are the key points to prevent sever complications during LC. Reasonable and feasible treatment is the ensurement of increasing the living quality of the patients with sever complications after LC. And the surgeons of biliary department must have a correct attitude toward LC and should concern think highly during LC and should not pursue speed blindly. In necessary, the operation of LC should be turned into open cholecystectomy.
摘要:目的:探讨床旁超声检查在肝移植术后下腔静脉(IVC)并发症诊断中的应用价值。方法:对424例肝移植术后患者进行床旁超声检查,对下腔静脉并发症,包括狭窄及栓塞的资料进行回顾性分析和总结。结果:床旁超声检查发现下腔静脉并发症患者18例,其中狭窄6例,栓塞12例。结论:床旁超声检查在肝移植术后,尤其是对术后早期发生的下腔静脉并发症的诊断及监测具有重要的作用,为临床诊断和治疗提供及时、有价值的影像学依据。Abstract: Objective: To evaluate the value of bedside ultrasound in diagnosis and monitoring of inferior vena cava (IVC) complications after liver transplantation. Methods: 424 cases with liver transplantation were examined by bedside ultrasound after the operations. The results of IVC complications,including thrombosis and stenosis, were analyzed and summarized. Results: 18 cases with IVC complications were detected by bedside ultrasound, including 6 cases of stenosis and 12 cases of thrombosis. Conclusion: Bedside ultrasound is important for diagnosing and monitoring IVC thrombosis and stenosis after liver transplantation, especially in the earlier period. It could provide valuable imaging for clinical diagnosis and treatment promptly.
