疏血通对肢体动静脉内瘘的保护应用

目的：探讨疏血通注射液促进肢体动静脉内瘘（AVF）术后成熟的疗效及治疗AVF血栓性阻塞的效果。方法：用疏血通注射液和香丹注射液于AVF手术后预防性治疗各50例,用疏血通注射液和尿激酶治疗AVF阻塞各20例,每日1次,7d为1疗程;对比AVF成熟情况、复通效果、透析时能达到的最大血流量及用药前后血液流变学改变。结果：疏血通促进AVF成熟良好率显著高于香丹（χ^2=4.336,P〈0.05）。疏血通与尿激酶对内瘘部分阻塞的复通效果相当,但对完全阻塞无效。疏血通和尿激酶治疗后血浆黏度值和纤维蛋白原均显著下降（P〈0.01）;而香丹注射液虽能改善血浆黏度值和红细胞聚集指数,但对纤维蛋白原无影响（P〉0.05）。结论：疏血通注射液能更好地促进肢体动静脉内瘘术后血管通路成熟,并能替代出血风险较大的尿激酶治疗AVF血栓形成致血管部分阻塞,可作为维护HD血管通路的常规治疗用药。     

直肠癌术后直肠阴道瘘的危险因素分析

目的 探讨直肠癌术后直肠阴道瘘的危险因素与临床对策.方法 回顾分析1997～2008年1123例女性直肠癌手术患者的临床资料,应用SPSS软件对数据进行统计处理,采用X2检验.结果 34例(3.03%,34/1123)术后出现直肠阴道瘘.直肠阴道瘘发生与患者有无绝经、肿瘤距肛缘的距离、肿瘤位于直肠壁的部位、吻合方式密切相关(P<0.05),而与患者年龄、肿瘤T分期、术前放疗、预防性造口等无明显相关.34例患者中12例经保守治疗后自愈,余22例患者均在瘘后3月局部炎症消退后行修补术,在修补直肠阴道瘘的同时行近端肠造口使粪便转流.结论 直肠癌术后直肠阴道瘘与患者有无绝经、肿瘤距肛缘的距离、肿瘤位于直肠壁的部位、吻合方式密切相关.熟悉其病因,加强围手术前准备,选择正确的手术时机和手术方式可降低直肠阴道瘘的发生率.     

流产手术后妊娠物残留疑似子宫动静脉瘘鉴别诊治分析

子宫动静脉瘘(uterine arteriovenous fistula,UAVF)属于子宫血管病变,是指子宫动脉分支与静脉分支之间绕过毛细血管网出现异常的直接交通.获得性UAVF常继发于子宫的创伤;由于流产手术后妊娠物残留与UAVF的B超表现存在一定的相似性,可能会干扰UAVF诊断的准确性.报道1例流产手术后B超提示...     

Fistulectomy as a surgical option for pulmonary arteriovenous malformation

Background Surgical resection remains the treatment of choice for pulmonary arteriovenous malformation but removes some normal lung parenchyma. This study aimed to evaluate the effect and safety of the lung-saving procedure of fistulectomy as an alternative to lung resection. Methods From July 2003 to July 2008, 6 selected patients with pulmonary arteriovenous malformations underwent fistulectomies. Among them, 1 patient underwent emergency operation and 2 underwent bilateral operations. One patient received postoperative embolotherapy. Results No hospital deaths or postoperative morbidity occurred. PaO2 increased significantly after operation. All patients were free of symptoms and hypoxia during a follow-up for 9 months to 5 years. Conclusions Fistulectomy is a safe and effective procedure for patients with pulmonary arteriovenous malformation and may be an alternative to lung resection.     

Case Report—Complex Management of a Postoperative Bronchogastric Fistula After Laparoscopic Sleeve Gastrectomy

Laparoscopic sleeve gastrectomy (LSG) is a new restrictive bariatric procedure increasingly indicated in the treatment of morbid obesity. Postoperative complications are mainly represented by gastric fistula with an occurrence rate of 0% to 5.1% in the literature. This complication is difficult to manage and requires multiple radiological, endoscopic, and surgical procedures. We report herein the case of a 23-year-old woman who underwent LSG for morbid obesity. This patient was reoperated for peritonitis due to a gastric fistula located on the top of the staple line. Five months later, she complained of a cough with fever and expectoration. A methylene blue test and a computed tomography scan diagnosed a postoperative bronchogastric fistula. After failure of aggressive conservative management, radical surgery was performed with total gastrectomy, reconstruction of the diaphragm using the extended latissimus dorsi flap, and a pulmonary lobectomy. This case report highlights the possible issue of the complex management of gastric fistula after LSG.     

可脱性球囊栓塞治疗外伤性颈内动脉海绵窦瘘

目的：探讨可脱性球囊栓塞治疗外伤性颈内动脉海绵窦瘘的临床意义。方法：应用可脱性球囊经动脉途径栓塞治疗21例颈内动脉海绵窦瘘。结果：21例患者中,瘘口栓塞17例,闭塞颈内动脉4例,均治愈。其中瘘口栓塞后1例并发球囊早泄瘘口复发,经再次球囊栓塞成功。颈内动脉通畅率为80.9%。随访3-6个月未见复发。结论：可脱性球囊栓塞术是治疗外伤性颈内动脉海绵窦瘘的首选术式。     

High resolution spiral CT scan in the diagnosis of pseudoaneurysm of ascending aorta

Pseudoaneurysms of the ascending aorta are rare (<1%), and extremely rare from aortic vent site, but can be a lifethreatening complication. The basic methods of diagnosis are computed tomography scan and aortography. We report high resolution spiral CT may provide the best less invasive means in the diagnosis of the pseudoaneurysm of the ascending aorta originated from the aortic vent site.
