Portal vein cannulation:An uncommon complication of endoscopic retrograde cholangiopancreatography

Portal vein cannulation is a rare complication of endo-scopic retrograde cholangiopancreatography(ERCP).It has been reported that it usually occurs after endo-scopic sphincterotomy,whereas in cases without prior sphincterotomy,the presence of portobiliary fistulas has been shown.Here,we present a case in which cannulation of the portal vein occurred despite careful wire-guided cannulation and the absence of sphinc-terotomy.Although fatal cases of cerebral and pulmo-nary air and/or bile embolism have been reported in patients with combined portal and hepatic vein trauma after ERCP and sphincterotomy,isolated portal vein cannulation,as in the current case,does not usu-ally result in mortality or serious morbidity.However,awareness of this rare complication is important so that no further intervention is performed.

ePTFE原位移植治疗吸毒者假性股动脉瘤15例

目的探讨吸毒致假性股动脉瘤的外科治疗方法。方法采用ePTFE原位移植法治疗15例吸毒致假性股动脉瘤患者。结果15例经过瘤体和毁损血管切除，彻底清创，ePTFE人造血管（膨体聚四氯乙烯人造血管）原位移植，全部保肢成功，无人造血管感染。经3～28个月随访，移植血管通畅。结论吸毒致假性股动脉瘤患者，病例选择得当，原位血管重建可行。
