Dissecting Aneurysms

Abstract BACKGROUND Dissecting aneurysms of the intracranial vertebral arteries are rare; however, treatment of these presents multiple challenges, including high risk of rebleeding, development of thromboembolic strokes, and progressive partial thrombosis. Flow diverters, such as Pipeline Endovascular Devices (PEDs; Covidien, Medtronic Inc, Dublin, Ireland), have emerged as a potential treatment option. OBJECTIVE To present our experience with patients treated at our institution with PEDs for dissecting distal vertebral artery (V4 segment) aneurysms. METHODS A retrospective search of our prospectively maintained database was performed between January 2014 and December 2016. We queried our database for all patients treated with PED for dissecting aneurysms of the V4 segment. Information was gathered including demographics, the location and morphology of the aneurysm, the clinical presentation, specific form of treatment, complications, antiplatelet medication regimen, and follow-up time. RESULTS There were a total of 9 patients with dissecting V4 aneurysms treated with PED during the study period. All were treated initially with an average of 1.2 PEDs. All patients were followed with at least one repeat diagnostic angiogram and there was no residual aneurysm seen in 8 of 9 cases. In those that presented with neurological deficits, there was an average improvement in modified Rankin Scale of 2.85 points. CONCLUSION PED is a safe and effective tool that can be used to treat ruptured dissecting aneurysms of this specific segment of the posterior circulation, but it does require close management of antiplatelet therapy in the setting of subarachnoid hemorrhage and close angiographic follow-up.

✓ Deliberate occlusion of the basilar or vertebral arteries was performed in 201 patients with intracranial aneurysms, where the aneurysmal neck could not be clipped directly. The aneurysms arose from the basilar apex in 83 cases, the basilar trunk in 46, the vertebrobasilar junction in 35, and the vertebral artery in 37; 87% of the aneurysms were classified as giant lesions (> 2.5 cm). There were 85 upper basilar occlusions, 41 lower basilar occlusions, 29 bilateral vertebral occlusions, and 48 unilateral vertebral artery occlusions. The clinical follow-up period varied from 1 to 23 years, with a mean of 9.5 years. Overall long-term results were excellent in 68% of the patients, good in 5%, and poor in 3%; 24% died. Clinical outcome varied according to aneurysm site; excellent or good results were achieved in 64% of the patients with basilar apex, 76% with basilar trunk, 74% with vertebrobasilar junction, and 87% with vertebral artery aneurysms. Clinical outcome also varied depending on preoperative grade: 86% of the patients with an excellent presenting grade achieved excellent results. The size of the posterior communicating arteries was a good predictor of tolerance to basilar artery occlusion (p < 0.05). Successful aneurysm thrombosis was achieved in 78% of the patients. The neurological status in 26 patients (13%) deteriorated due to vertebrobasilar ischemia occurring within the 1st postoperative week, and thrombosis or embolism was implicated much more frequently than hemodynamic insufficiency. Subarachnoid hemorrhage (SAH) in 14 patients, vasospasm in five patients, and surgical trauma in seven patients accounted for additional morbidity in the 1st month following operation; however, many of these patients ultimately made an excellent recovery. Late vertebrobasilar ischemic complications or neurological deterioration from persistent mass effect occurred in 4% of patients with successful aneurysm thrombosis 6 weeks to 18 months after arterial ligation. Among the 43 patients with incompletely thrombosed aneurysms, 67% developed early or late neurological deterioration from SAH, progressive brain-stem compression, or brain-stem stroke, with 86% of the complications proving fatal.
