Six patients developed postprocedural malignant edema and hemorrhage (group M); the other 66 patients had no malignant edema and hemorrhage (group NM). In each patient, flow was assessed indirectly by summing the diameters of all feeding arteries to obtain an overall diameter (ODA), and similarly for draining veins (ODV). High-flow was defined as a delay between feeding artery injection and draining vein injection (DAV) < 1 second on dynamic digital subtraction angiography. Univariate analysis was performed.ResultsMean ODA and ODV were respectively 11 mm (± 8.2) and 11 mm (± 5.3) in group M and 2.9 mm (± 1.4) and 3.7 mm (± 1.3) in group NM (P = 0.001). High-flow AVM was demonstrated in 4 out of 5 patients (85%) in group M and in 14 out of 55 (25%) in group NM (P = 0.02). Associated aneurysm was seen in 5 patients in group M (83%) and in 11 in group NM (17%) (P = 0.001).ConclusionHigh-flow AVM may be associated with higher risk of postoperative edema and hemorrhage. Multidisciplinary discussion is mandatory in these cases, to define a pre-therapeutic plan for progressive staged vascular malformation occlusion.Show less >
