Stent-assisted coiling of paraclinoid aneurysms: risks and effectiveness.
Stent assistance for treatment of wide-based aneurysms is becoming rapidly accepted. ⋯ Stent-assisted coiling of paraclinoid aneurysms did not add significantly to morbidity; overall effectiveness was comparable to that of bare coiling of paraclinoid aneurysms. These results require confirmation by a prospective controlled trial.

Spinal dural arteriovenous fistulas (SDAVFs) represent the most frequent spinal arteriovenous malformation and have an ominous natural history if left untreated. In the present review, we describe the spinal vascular anatomy, pathophysiology and clinical manifestations of SDAVFs, and the current role of endovascular embolization in this type of lesion.

Cerebral arteriovenous malformations (AVMs) are vascular lesions that are amenable to various treatment modalities including stereotactic radiosurgery, fractionated radiotherapy, endovascular embolization, microsurgical obliteration or combined modality treatment. A potential complication of endovascular therapy with embolization material is microcatheter entrapment. We report on a patient for whom surgery was combined with endovascular embolization to obliterate an AVM and retrieve an entrapped endovascular microcatheter. ⋯ This demonstrates the first incidence of microcatheter removal after procedural entrapment in Onyx embolization material.
