The study was a retrospective review of giant intracranial aneurysms treated by superficial temporal artery to middle cerebral artery bypass combined with endovascular occlusion of the parent artery. From 1990 to 2003, 29 consecutive cases of giant cerebral aneurysms, not suitable to selective treatment were managed in that way. Twenty-one medical records had enough data to allow objective evaluation. Sixteen female and five male patients bearing 21 giant aneurysms were involved. Their mean age was 46 years. The aneurysm was revealed by mass effect in 13 cases and subarachnoid hemorrhage in one case. On admission 19 patients presented with unruptured aneurysms and two have sustained a subarachnoid hemorrhage. The balloon occlusion test before the bypass operation was not tolerated in 18 patients. The treatment was completed in 19 patients and 17 of them had parent artery occlusion with latex detachable balloons. The only death of the series occurred before the endovascular treatment. The mean follow-up period was 30 months. After completion of the treatment, 16 (84%) patients had no symptom. Aneurysm recanalization or rupture was not observed after the parent artery occlusion. With the combination of superficial temporal artery to middle cerebral artery bypass + endovascular parent artery occlusion, 90% of giant intracranial aneurysms untreatable selectively were permanently excluded with a good outcome in 95%.展开更多

This study was designed to evaluate the resolution of symptoms after parent artery occlusion (PAO) treatment for giant CCAAs. Methods: We retrospectively reviewed a series of 17 consecutive giant CCAAs treated with PAO treatment. All patients were evaluated by balloon occlusion test (BOT) before treatment. Patients who could tolerate BOT were treated by PAO. The following outcomes were analyzed: angiographic assessment, evolution of symptoms and outcome at clinical follow-up using modified Rankin Scale (mRS). Results: A total number of 17 giant CCAAs were treated by PAO. The initial post-procedure and follow-up angiogram revealed complete occlusion in all patients, no new lesion was detected. Periprocedural infarcts occurred in 1 patient (5.9%). Procedure-related mortality and morbidity were 0% and 5.9%, respectively. At mean 31.8 months clinical follow-up, symptoms had disappeared in 7 (41.2%) of the patients, partially improved in 5 (29.4%), remained unchanged in 4 (23.5%) and worsened in 1 (5.9%) of cases. Sixteen (94.1%) patients presented a good clinical outcome (mRS 0 - 1). Conclusion: Most patients in our series improved or remained stable after PAO. The results of this study indicate that PAO can improve the outcome of those symptomatic giant CCAAs if BOT can be tolerated.展开更多

Both patients experienced a rapid development of de novo aneurysm formation, 6 and 9 months, respectively. The development of de novo aneurysm on the contralateral artery after parent artery occlusion showed that female and medium age may be contributory factors. In addition, the hemodynamic changes may be associated with the development of de novo aneurysm after contralateral parent artery occlusion.展开更多
