چکیده
AIM To understand the late anatomical results of surgically treated intracranial aneurysms (IA's) and to investigate the incidence of recurrent, de novo aneurysms, the natural history of residual aneurysms, and the morphological changes in temporarily clipped vascular segments. MATERIAL AND METHODS A total of 117 patients underwent screening with digital subtraction angiography (DSA) or computed tomographic angiography (CTA) in a range of 3 - 13 years. Late angiographies were evaluated in terms of recurrence, change in known residua, the presence of de novo aneurysms and the morphological changes in temporarily clipped vessels. We also analysed the cumulative data including previously published results. RESULTS In the long-term DSA, three residual aneurysms were observed to be enlarged while four remnants showed no morphological change. In one patient, spontaneous obliteration was seen. No recurrent aneurysm was detected. One de novo aneurysm was observed. We did not find any morphological change in 71 temporarily clipped vascular segments. CONCLUSION Our data demonstrates that completely occluded aneurysms could remain stable even years later. Most of the small neck residues appeared to remain unchanged or even be thrombosed but they should be carefully followed. The incidence of de novo aneurysms might be expected to be lower.

Risk of subarachnoid hemorrhage after surgical treatment of unruptured cerebral aneurysms.
BACKGROUND AND PURPOSE Recent progress in noninvasive imaging techniques has resulted in increased detection of unruptured aneurysms. Although many neurosurgeons advocate surgical intervention for such unruptured aneurysms, the long-term results of surgery for unruptured aneurysms have not been carefully investigated. METHODS We analyzed 173 consecutive patients who had unruptured intracrania...

AIM We report our experience with flow diverter devices in the treatment of intracranial aneurysms arising from anterior circulation with mid and long-term follow-up. MATERIAL AND METHODS 78 aneurysms in 61 patients (range 25-81 years, 13 male, 48 female) were treated with flow diverter devices. 40 (51,3%) aneurysms were treated with pipeline embolization device (PED), 24 (30,8%) aneurysms we...
متن کاملRates of Delayed Rebleeding From Intracranial Aneurysms Are Low After Surgical and Endovascular Treatment
Background and Purpose—Although results of the randomized International Subarachnoid Aneurysm Trial suggested that coil embolization was superior to surgical clipping 1 year after treatment, a paucity of data on long-term outcomes has been a major concern. Methods—In an ambidirectional cohort study, 9 institutions with expertise in intracranial aneurysm treatment identified all ruptured saccula...
