Background Massive presacral venous plexus hemorrhage during radical resection of rectal carcinoma is rare, but when it occurs, bleeding can be uncontrollable, leading to death in some cases. Medical adhesive gauze sticking and packing and thumbtack compressive fixation are often used for hemostasis, but these methods are not effective in cases of uncontrollable massive hemorrhage. Therefore, identifying a practical, accurate, and reliable method of hemostasis in these cases is *** Between January 2004 and December 2009, we treated 3 patients with massive presacral venous plexus hemorrhage during resection of rectal carcinoma by placing small, trimmed thin steel plates at the bleeding sites. The plates were fixed with a saddle-type application of *** Bleeding was successfully controlled in all 3 patients, and intestinal anastomosis was carried out after hemostasis. No complications were *** Application of a small, thin steel plate to the bleeding site with thumbtack fixation is a simple and effective method of hemostasis in patients with massive presacral venous plexus hemorrhage during resection of rectal carcinoma.

目的:观察玻璃体腔内注射康柏西普治疗近视性脉络膜新生血管(myopic choroid neovascularization,mCNV)的疗效。方法:回顾性分析2013-01/2016-12于湖南省人民医院眼科诊断为mCNV的患者15例16眼的临床资料,根据病情行玻璃体腔注射康柏西普1次或1次以上,治疗后随访1.5~28mo,观察患者治疗前后最佳矫正视力(BCVA)和黄斑区视网膜厚度的变化。结果:本研究纳入患者15例16眼,均行玻璃体腔注射康柏西普治疗,其中6眼治疗1次,7眼治疗2次,3眼治疗3次,重复注射者每次治疗时间间隔均为1mo。治疗前平均眼压(16.44±1.39mmHg)和治疗后末次随访时(16.75±1.41mmHg)比较,差异无统计学意义(P>0.05)。治疗后末次随访时BCVA(0.71±0.21)较治疗前(1.14±0.35)显著改善,差异有统计学意义(P<0.05)。治疗后末次随访时黄斑区视网膜厚度(287.25±30.31μm)较治疗前(361.63±33.59μm)降低,差异有统计学意义(P<0.05)。治疗及随访期间,未出现眼内炎、脑卒中、视网膜脱离等严重并发症或不良反应。结论:玻璃体腔内注射康柏西普能在短期内改善mCNV患者的视力,有利于减少黄斑中心凹视网膜厚度,且并发症较少,临床应用相对安全。
