门静脉动脉化在肝门部血管重建中的运用（附6例报道）

Applications of portal vein arterialization to hilar vascular reconstruction (a report of 6 cases)

摘要:

目的  探讨门静脉动脉化在肝门部血管重建中的作用。方法  对6例侵犯肝动脉的围肝门区恶性肿瘤，均行联合肝叶切除的根治性手术，并联合对受侵的肝动脉切除，并行门静脉与肝动脉近端合适部位的吻合，完成门静脉动脉化处理。结果  本组病例围手术期无死亡及肝功能衰竭的发生。术后病理根治性切除率为100%。术后观察6个月以上，未见门脉高压和肝损害的出现。结论  在肝动脉受肿瘤侵犯被迫切除时，根据剩余肝体积的多少，选择合适的肝动脉口径行门静脉动脉化，不失是一种保留肝动脉血供的方法。不仅可以提高手术的切除率，而且可降低术后并发症的发生率。

Abstract:

Objective To explore the function of portal vein arterialization in hilar vascular reconstruction. Methods Six cases with hepatic artery invasion of peri-hilar malignant tumors were treated with resection of involved hepatic artery, portal vein and hepatic artery anastomosis, and hepatectomy for radical resection. Results There was no mortality or liver failure in peri-operation stage. The pathological radical resection rate was 100% in the 6 cases． Neither portal hypertension nor liver function damage was detected during the postoperative six months. Conclusions In the hepatic artery invasion cases, portal vein arterialization through vascular anastomosis with hepatic artery of appropriate calibre is a worth recommended operational method to enrich liver arterial blood supply and reduce the rate of postoperative complications.
