Background The Raymond–Roy Occlusion Classification (RROC) is the standard for
evaluating coiled aneurysms (Class I: complete obliteration; Class II: residual neck; Class III …

BACKGROUND: With the increasing use of endovascular techniques in the treatment of both
ruptured and unruptured intracranial aneurysms, the issue of obliteration efficacy has …

Background: The objective of our project was to identify a late recanalization predictor in
ruptured intracranial aneurysms treated with coil embolization. This goal was achieved by …

Background and purpose The Raymond–Roy grading scale is used for aneurysm coiling
with only limited data on its validity. The scale was developed based on the extent of initial …

Background Aneurysmal recanalization is a problem with endovascular coiling and one of
its risk factors is the low volume embolization ratio (VER). The first coil VER (1st VER) is …

OBJECTIVE The importance of a framing coil (FC)—the first coil inserted into an aneurysm
during endovascular coiling, also called a lead coil or a first coil—is recognized, but its …

Purpose Endovascular therapy for the treatment of cerebral aneurysms has a higher
incidence of rebleeding and a lower occlusion rate than microsurgical clipping. This study …

Background Subtotal coil embolization followed by subsequent flow diversion is often
pursued for treatment of acutely ruptured aneurysms. Owing to the need for anti-platelet …

Background Treating recurrence after coil embolization of basilar tip aneurysm remains
challenging even with the development of endovascular procedures. The present study …

Background: Large wide-necked arterial bifurcation aneurysms present a unique challenge
for endovascular coil embolization treatment. One technique described in the literature …
