肝癌化疗栓塞术对肝脏血流动力学和储备功能的影响

1目的　探讨化疗栓塞术对肝癌病人肝脏血流动力学和肝储备功能 (HFR)的影响。2方法　对 17例肝癌病人行肝动脉插管化疗栓塞治疗 ,采用彩色多谱勒血流显像仪 (CDFI)显像、CT扫描测量的方法对栓塞前后的血流动力学和肝实质丢失率 (PHER)的改变进行临床观察。3结果　门静脉和脾静脉血流量、血流速度均于栓塞7d后明显上升 ,并达到高峰 (F=14.86～ 332 .5 5 ,q=6 .48～ 36 .43,P<0 .0 1) ,以后逐渐回落至栓塞前水平 ,而血管内径于栓塞前后无明显改变 ;门静脉充血指数 (CI)于栓塞前后无明显改变 (t=1.45 ,P>0 .0 5 ) ;栓塞后 PHER为10 .6 3%～ 43.83% ,平均 2 6 .13% ,多数病人 PHER<40 %时 ,栓塞后 HFR能满足术后代偿需要。4结论　对门静脉血流动力学的定量分析为肝动脉化疗栓塞术的预后估计提供了重要资料。综合 PHER可以正确评估栓塞对肝脏HFR的影响。     

脑膜瘤术前颈外供血动脉超选择栓塞治疗

目的 回顾40例脑膜瘤施行术前血管内栓塞治疗,阐明栓塞的效果。方法 40例幕上脑膜瘤均行术前超选择颈外供血动脉明胶微粒栓塞,栓塞后1－7d行开颅脑膜瘤切除。结果 肿瘤单纯颈外供血19例,颈内、颈外均参与供血21例（其中颈内为主6例）。肿瘤全切除38例,大部分切除2例,无栓塞相关并发症。结论 单纯颈外供血或主要颈外供血者,栓塞后3－7d施肿瘤切除术,术中出血明显减少,手术时间显著缩短,并发症少。超选择栓塞治疗能减少栓塞治疗本身的并发症,是一种安全而有效的辅助治疗。

Prognostic value of the Spetzler's grading system in a series of cerebral AVMs treated by a combined management

Summary The prognostic value of the Spetzler's grading system is studied in a series of 52 AVMs treated by a combined management, using one or several of the 3 available techniques: surgical resection, endovascular embolization, radiosurgery.The symptoms at the time of treatment were haemorrhage 50%, seizures 31%, headache and deficit 19%. Three grade groups were considered: I and II (31%), III (33%), IV and V (36%). Overall, AVMs were managed as follows: resection alone 25%, embolization plus resection 23%, embolization alone 23%, radiosurgery with various combinations 29%. According to the grade groups, the most frequently used technique was resection alone for grade I–II AVMs (44%), radiosurgery for grade III AVMs (41%) and embolization alone for grade IV–V AVMs (42%).The clinical outcome was evaluated in terms of deterioration due to treatment. The best results were obtained in grade I–II AVMs (81% with no deterioration) then in grade III AVMs (65%) and in grade IV–V (58%). However, when we consider the outcome in terms of favourable results (no or only minor deterioration) we obtained a similar outcome for grade I–II and grade III AVMs (94% each), and only 79% for grade IV–V malformations. The angiographic outcome showed a better eradication rate in grade III AVMs (88% complete eradication), than in grade I–II AVMs (75%) and in grade IV–V (47%).Our conclusion is that the Spetzler's grading system in this series was well correlated with both the clinical and the angiographic outcome. However, we found no real difference between grade I–II and grade III AVMs. So, in terms of prognostic value, the grade I, II, and III AVMs could be considered together as low-grade malformations, with a better prognosis than the high-grade malformations (grade IV and V).
