Flow Diversion in Middle Cerebral Artery Aneurysms: Is It Really an All-Purpose Treatment?

Middle Cerebral Artery Bifurcation Aneurysms Treated by Extrasaccular Flow Diverters: Midterm Angiographic Evolution and Clinical Outcome

“…Contrary to the recent published results from a clinical study on fusiform/dissecting MCA aneurysms, which positively associated total occlusion rates with side branch occlusion, 19 our results did not show a correlation between side branch and saccular occlusion. On the contrary, an important percentage of the jailed branches remained patent.…”

“…Six-month angiographic controls in our study already showed important results in terms of aneurysm patency, but longer fol- low-ups revealed even further significant increases in total occlusion rates, as opposed to the study by Topcuoglu et al 19 In this study, 93% of immediate postprocedure circulating aneurysms progressed to 68% occlusion at 6 months and to 95% occlusion at 1 year. In this series, the rupture rate was 0% within the first year and beyond, similar to other recently published data.…”

Tapered flow diverters in the treatment of intracranial aneurysms

“…An approximately 9.63 times risk for aneurysmal remnants was found for aneurysms greater than 13 mm in largest size as compared to smaller aneurysms (11), and a higher rate for residual aneurysms was found on followup for aneurysms from which large side-branches originated (17).…”

The p48MW Flow Diverter—Initial Human Experience

“…The early use of flow diversion was centered on the treatment of aneurysms arising from the internal carotid artery (ICA) with 79/108 (73.1%) aneurysms treated in the PUFS study arising from either the cavernous or ophthalmic segments of the ICA and the majority of the aneurysms being between 10 and 25 mm in size (78.7%). Since the publication of this K p48MW pivotal trial, numerous reports on the use of flow diversion distal to the circle of Willis have been published [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Ravindran et al [26] recently reported their multicohort study of FDS use distal to the circle of Willis defined as at or beyond the A1, M1 and P1 segments of the ACA, MCA and PCA, respectively.…”
