Selective embolization of unruptured intracranial aneurysms is associated with low retreatment rate

Abstract

Selective embolization of UIA is associated with stable long-term anatomical results and low retreatment rate.

Vascular Geometry Change Because of Endovascular Stent Placement for Anterior Communicating Artery Aneurysms

“…12 Coil embolization alone had a higher proportion of residual aneurysm neck, especially in wide-neck aneurysms. 13 In patients with residual aneurysmal neck, rates of rebleeding and recurrence were higher than those with complete occlusion.…”

Factors influencing cerebral aneurysm obliteration and reliability of indocyanine green video-angiography

“…However, direct wall puncture is not considered safe in all patients. In patients with risk factors and in whom direct puncture is deemed unsafe, IA should be considered, a plan should be made for a second clipping procedure, and clinicians should be prepared to take an appropriate course of action in the event of new bleeding.The occurrence of false-negative findings suggests that a proportion of clipped aneurysms are likely to thrombose, as observed in cases of coiled aneurysms[2]. The fact that, in the two representative cases, aneurysm puncture resulted in a prominent blood flow, leads us to hypothesize that these aneurysms could have not thrombosed if left untreated.…”

Correlation Between Activated Clotting Time and Activated Partial Thromboplastin Time During Endovascular Treatment of Cerebral Aneurysms

“…The endovascular approach requires a precise and continuous anticoagulation in order to avoid thromboembolic complications [2]. Until now, no definitive guidelines have been formulated concerning the optimal anticoagulation regimen during these procedures [3]. Unfractionated Heparin (UFH) is generally used because of the possible titration and because it can be reversed with the administration of protamine sulphate.…”
