Abstract
Arteriovenous abnormalities of cerebral vessels are quite common. One of the main manifestations of this pathology are arteriovenous malformations. Also, a combination of malformations with aneurysmal expansion of the vascular wall of various localization is not rare.
Highlights
Arteriovenous malformations (AVMs) of the brain are much less common than arterial aneurysms and are observed in 1.3 per 100,000 of the population per year [1]
In patients with unruptured AVMs, the treatment strategy of the associated aneurysm(s) follows the criteria applied to the treatment of unruptured incidental aneurysms in general, with the caveat that some aneurysms hemodynamically connected to the AVM may decrease in size or even disappear after treatment of the AVM
In one study, which analyzed the fate of untreated aneurysms associated with AVMs after treatment of the AVM, 4 of the 5 (80%) distal flow-related aneurysms disappeared after complete excision of the AVM, and only 1 (20%) was unchanged
Summary
Arteriovenous malformations (AVMs) of the brain are much less common than arterial aneurysms and are observed in 1.3 per 100,000 of the population per year [1]. We present one of the options for endovascular treatment of AVM and aneurysm with a liquid embolic agent in a patient with a previous hemorrhage. Arteriovenous malformation (AVM) in the right fronto-parietal region (Spetzler-Martin 4) with proximal flow-related aneurysm of the right anterior cerebral artery (ACA). An arteriovenous malformation of the fronto-parietal region (Spetzler-Martin 4) was detected with proximal flow-related aneurysm of the right anterior cerebral artery measuring 11.5 × 7.0 × 6.0 mm with the neck size 5.0 mm. We performed control CT - angiography (Figure 6) and perfusion (Figure 7) after an hour to evaluate the volume of the embolized AVM site and identify the potentially dangerous rupture zones during blood flow distribution.
