Efficacy of preoperative portal vein embolization prior to major hepatectomy for patients with impaired liver function: A retrospective study

Hepatocellular carcinoma (HCC) is often associated with chronic liver disease, such as hepatitis or cirrhosis, and this association may limit the use of surgery as a therapy, and if surgery is pursued, may give rise to postoperative hepatic failure. We evaluated the outcome in patients with HCC given preoperative portal vein embolization (PVE) before they underwent major hepatectomy. After PVE, portal pressure increased significantly. Two weeks after PVE, both the volume of the non-embolized lobe and the 15-min indocyamine green retention rate (ICG R15) were significantly increased. The prognostic score, calculated on the basis of age, ICG R15, and the resection rate, was significantly decreased. The operative mortality rate was significantly lower in patients who underwent PVE before surgery than in patients who did not receive PVE. The cumulative survival rate of the PVE patients, even those with cirrhosis of the liver, was significantly higher. Prior PVE appears to allow more extensive major hepatectomy and to lessen the risk of this invasive surgery. However, patients in whom the portal pressure immediately after PVE was more than 30cm H₂O and/or whose prognostic score exceeded 50 points developed postoperative hepatic failure. These features should be kept in mind when it is decided whether surgery is indicated. Nevertheless, preoperative PVE appears to be a beneficial procedure for patients undergoing major hepatectomy, particularly those with chronic liver disease.     

头面部复杂动静脉畸形的栓塞治疗

目的　研究经导管栓塞技术在头面部动静脉畸形治疗中的应用。方法　 3 0例头面部动静脉畸形患者共接受 40次栓塞治疗。其中使用国产TH胶栓塞者为 18例 2 0次 ,使用进口PVA微粒栓塞者为 12例 2 0次。结果　 3 0例患者均成功实行瘤灶供血动脉栓塞术。所有患者栓塞术后临床症状明显改善 ,如瘤体缩小甚至消失 ,皮温降低 ,搏动感和血管杂音减弱或消失等。术后随访3～ 6个月 ,12例复发。全部病例均无严重并发症。结论　对于头面部动静脉畸形的患者来说 ,经导管栓塞术是一种较好的非手术治疗方法 ,在栓塞剂的选择方面 ,则以PVA微粒栓塞更为理想。     

Technique for ipsilateral rescue embolization of common femoral side branch vessel injury.

We report a novel double wire technique for ipsilateral access of the external iliac/common femoral artery transition side-branches in a patient with active extravasation. The case is noteworthy in that asymptomatic extravasation was noted in both the inferior epigastric and deep circumflex iliac branches on femoral angiography prior to intraaortic balloon pump insertion following emergent diagnostic left heart cathetrization. We speculate the side branch injury was related to the J-wire and describe how this complication may be best treated by the ipsilateral technique reported herein.     

规范化介入治疗方案在肝癌经导管介入治疗中的指导意义

目的探讨规范化介入治疗方案在肝癌经导管介入治疗中的意义。方法回顾性分析实施规范化方案治疗前后患者生存率的变化。结果实施规范化方案后能明显提升患者生存率。结论规范化方案在肝癌经导管介入治疗中具有重要的指导意义。     

不明原因下消化道出血的血管造影及导管治疗

目的：明确下消化道出血原因及止血治疗。材料与方法：对21例不明原因下消化造出血病人行选择性血管造影，并经导管灌注垂体后叶素、明胶海绵条栓塞。结果：血管造影诊断阳性率为76％，16例病人治疗后均止血。结论：血管造影是诊断不明原因下消化道出血的首选方法，垂体后叶素灌注短期（1周）止血效果显著，但易复发，栓塞治疗更重要的在于确定病变部位以利手术。

脑血管母细胞瘤的外科治疗(附38例报告)

目的总结、探讨脑血管母细胞瘤的外科治疗。方法对38例脑血管母细胞瘤的临床表现、手术治疗进行回顾分析。结果30例囊性肿瘤均行瘤结节全切除术;随防3～20年,未复发29例。8例实体性肿瘤中,4例先行血管内栓塞后行全切除术,另4例因术中大出血行大部分和部分切除;随访3～12年,全切除的4例未复发,非全切除者1例无变化,1例增大,2例死亡。结论囊性血管母细胞瘤外科治疗易做到全切除,疗效好。实体性血管网状细胞瘤外科治疗因血管丰富,可先行血管内栓塞,减少术中出血量,提高切除率。
