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).     

肝癌介入治疗药动学及其临床意义探讨

本研究通过测定血清阿霉素浓度,分析了原发性肝癌阿霉素肝动脉灌注(A 组)、阿霉素碘油乳化后栓塞(B 组)及阿霉素微囊栓塞化疗(C 组)后药动学变化及其临床意义。A 组药动学变化与静脉给药相似,但峰值浓度高。B 组峰浓度低,半衰期延长,显示缓释和降低血浓度的作用。C 组峰浓度不明显,表现为长时、稳定的释放,血浓度低,具有保持局部长时间高浓度作用。结果揭示了肝癌介入治疗不同给药方法疗效差异的药动学依据。

肝动脉栓塞化疗对原发性肝癌患者肝纤维化指标的影响

为探讨重复肝动脉化疗（TAE）对原发性肝癌（PHC）患者肝脏损伤的影响,对40例经3次TAE治疗的PHC患者和25例肝血管瘤患者（经1次TAE治疗）测定治疗前后透明质酸（HA）,层粘连蛋白（LN）,人Ⅲ型前胶原（HpcⅢ）和Ⅳ型胶原（Ⅳ·C）的含量。结果发现第2次TAE治疗后,上述4项指标TAE前后均有显著性差异（P＜0．05）,以第3次TAE后升高最为明显（P＜0．01）。提示重复TAE治疗常可加重PHC患者的肝损害,应引起足够的重视。
