“…7,19 In the Wessels et al series, 7 complete recanalization was found in 64% of patients, whereas De Bray et al 17 reported complete recanalization in 9 (50%) of 18 patients with intracranial VAD and in 4 (36%) of 11 with extracranial VAD. Using digital subtraction angiography as the follow-up technique, Lee et al 18 found complete recanalization in 63% of the 19 patients with VAD with a mean time to achieve complete recanalization of 8.6 months (range, 3 weeks to 56 months) by combining data from 37 VAD cases.…”

“…обнаружили, что реканализа-ция происходит в основном в течение первых 6 меся-цев после появления симптомов заболевания [6]. Тем не менее изучение ДПА с помощью дуплексно-го ультразвукового сканирования остается сложной задачей из-за небольшого размера позвоночных арте-рий, их глубокого залегания, частых анатомических вариаций и особенностей близлежащих структур [7,8]. Магнитно-резонансная ангиография (МРА) и компьютерная ангиография (КТА) имеют потенци-альные преимущества в отношении неинвазивного исследования заболеваний экстракраниальных сосу-дов и ранее доказали свою полезность для выявления ДПА [9][10][11].…”

“…However, the evaluation of VAD by using duplex ultrasonography remains difficult because of the small size of the vertebral arteries, their deep location, frequent anatomic variations, and surrounding structures. 7,8 MR angiography (MRA) and CT angiography (CTA) offer potential advantages for the noninvasive assessment of extracranial vascular disease and have previously been proven useful for the detection of VAD. 9 -11 Sequential neuroimaging examinations can indicate recanalization or normalization of the blood flow and may be helpful for the decision to discontinue antithrombotic therapy.…”

Background and Purpose-We investigated the predictors and time course for recanalization after vertebral artery dissection. Methods-We prospectively studied 61 consecutive patients with confirmed diagnoses of vertebral artery dissection without intracerebral hemorrhage. Neuroimaging and clinical follow-up were performed at presentation and at 3, 6, and 12 months. Results-We included 61 patients with confirmed vertebral artery dissection; 19 were evaluated and followed up with conventional angiography, 24 with MR angiography, and 18 with CT angiography. Fifty-one patients had a stenotic dissection, 7 had an occlusive dissection, one had a double-lumen image, and 2 had a pseudoaneurysm. The estimated rate of complete recanalization after vertebral artery dissection was 45.9% at 3 months, 62.3% at 6 months, and 63.9% at 12 months. We found no association between outcome and complete or partial recanalization nor did we find any factors associated with recanalization. Conclusions-These results suggest that recanalization of vertebral artery dissection occurs mainly within the first 6 months after the onset of symptoms regardless of the location or pattern of the dissection.

Pathomechanisms and treatment of pediatric aneurysms

Pediatric aneurysms are rare diseases distinct from classical adult aneurysms and therefore require different treatment strategies. Apart from saccular aneurysms that are more commonly found in older children, three major pathomechanisms may be encountered: trauma, infection, and dissection. The posterior circulation and more distal locations are more commonly encountered in children compared to adults, and there is an overall male predominance. Clinical findings are not only confined to subarachnoid hemorrhage but may also comprise mass effects, headaches or neurological deficits. In traumatic aneurysms, the skull base and distal anterior communicating artery are commonly affected, and the hemorrhage occurs often delayed (2-4 weeks following the initial trauma). Infectious aneurysms are mostly bacterial in origin, and hemorrhage occurs early after a septic embolic shower. Dissecting aneurysms are the most often encountered aneurysm type in children and can lead to mass effect, hemorrhage, or ischemia depending on the fate of the intramural hematoma. Treatment strategies in pediatric aneurysms include endosaccular coil treatment only for the "classical berry-type" aneurysms; in the other instances, parent vessel occlusion, flow reversal, surgical options, or a combined treatment with bypass and parent vessel occlusion have to be contemplated.
