“…Cases that fulfilled the following criteria were included: sudden onset of ischemic or hemorrhagic symptoms, cerebral angiography showing characteristic arterial dissection findings [6, 7], arterial dissection in the intracranial portion on cerebral angiography, and no obvious atherosclerotic changes found in other intracranial arteries on cerebral angiography. Finally, the cerebral angiography findings must have been consistent with the clinical symptoms.…”

Background. Intracranial artery dissections are rare and many controversies exist about treatment options. The aim of this study was to evaluate the efficacy and safety of the endovascular approach in patients with an intracranial dissection presenting with different symptoms. Methods. We prospectively evaluated the clinical features and treatment outcomes of 30 patients who had angiographically confirmed nontraumatic intracranial dissections over 4 years. Patients were followed up for 17 months, and their final outcomes were assessed by the modified Rankin Score (mRS) and angiography. Results. Sixteen (53.3%) patients had a dissection of the anterior circulation, whereas 14 (46.7%) had a posterior circulation dissection. Overall, 83.3% of the patients suffered a subarachnoid hemorrhage (SAH). Grade IV Hunt and Hess score was seen in 32% of the SAH presenting cases. Parent artery occlusion (PAO) with coil embolization was used in 70% of the cases. The prevalence of overall procedural complications was 23.3%, and all were completely resolved at the end of follow-up. No evidence of in-stent occlusion/stenosis or rebleeding was observed in our cases during follow-up. Angiography results improved more frequently in the PAO with coil embolization group (100%) than in the stent-only-treated group (88.9%) (P = 0.310) and the unruptured dissection group (5/5, 100%) in comparison with the group that presented with SAH (95.8%) (P = 0.833). Conclusion. Favorable outcomes were achieved following an endovascular approach for symptomatic ruptured or unruptured dissecting aneurysms. However, the long-term efficacy and durability of these procedures remain to be determined in a larger series.

“…Intense pain of sudden onset in the craniocervical region is a prominent symptom in both presentations of IVAD. When it comes to SAH, even though there may be spontaneous healing, recurrent hemorrhage is common and may lead to death (1–7, 13).…”

“…Intracranial vertebral artery dissection (IVAD) is considered a rare condition. Two main clinical presentations have been described in the literature: subarachnoid hemorrhage (SAH) and ischemia due to thrombosis or embolism in the vertebrobasilar territory (1–8).…”

Extracranial vertebral artery (VA) dissections usually present with unilateral occipital-nuchal pain or headache, often followed by lateral medullary or cerebellum ischemia. Posterior cerebral artery (PCA) ischemia may also occur. Women predominate, and the dissections are most often bilateral. The distal extracranial and proximal VA segments are most often affected. Recovery is common, and the lesions usually regress. Intracranial VA dissections are found more often in men. The dissections are usually unilateral and often extend into the basilar artery (BA). Subarachnoid hemorrhage (SAH) and brainstem ischemia are the commonest presentations. Ischemia is often severe, and fatal infarctions are common. Occasionally, patients present with mass effect. Some patients have chronic bilateral VA dissections that cause repeated ischemia or recurrent SAH. BA dissections are rarer but also show a male preponderance. Severe, often fatal, ischemia is the commonest presentation. SAH is rarer. The dissections often extend into the distal BA and cause rostral BA, superior cerebellar artery and PCA territory infarction.
