AIM: To understand the late anatomical results of surgically treated @entity438 ( @entity438 ) and to investigate the incidence of recurrent, de novo @entity439 , the natural history of @entity439 , and the morphological changes in temporarily clipped vascular segments. MATERIAL AND METHODS: A total of 117 @entity1 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 @entity439 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 @entity439 were observed to be enlarged while four remnants showed no morphological change. In one @entity1 , spontaneous obliteration was seen. No recurrent @entity439 was detected. One de novo @entity439 was observed. We did not find any morphological change in 71 temporarily clipped vascular segments. CONCLUSION: Our data demonstrates that @entity439 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 @entity439 might be expected to be lower.
