Abstract BACKGROUND: Optimal management of bilateral vertebral artery dissecting aneurysms (bi-VDAs) causing subarachnoid hemorrhage (SAH) remains unclear. OBJECTIVE: To investigate the treatment methods and outcomes of bi-VDA causing SAH. METHODS: Seven patients were treated endovascularly for bi-VDA causing SAH. Treatment methods and outcomes were evaluated retrospectively. RESULTS: Two patients were treated with 2 overlapping stents for both ruptured and unruptured VDAs, 2 with 2 overlapping stents and coiling for ruptured VDA and with conservative treatment for unruptured VDA, 1 with internal trapping (IT) for ruptured VDA and stent-assisted coiling for unruptured VDA, 1 with IT for ruptured VDA and 2 overlapping stents for unruptured VDA, and 1 with IT for ruptured VDA and a single stent for unruptured VDA. None had rebleeding during follow-up (range, 15-48 months). All patients had favorable outcomes (modified Rankin Scale score, 0-2). On follow-up angiography at 6 to 36 months, 9 treated and 2 untreated VDAs revealed stable or improved state, whereas 3 VDAs in 2 patients showed regrowth. Of the 3 recurring VDAs, 1 was initially treated with IT but recurred owing to retrograde flow to the ipsilateral posterior inferior cerebellar artery (PICA), the second was treated with single stent but enlarged, and the last was treated with 2 overlapping stents and coiling but recurred from the remnant sac harboring the PICA origin. All 3 recurred VDAs were retreated with coiling with or without stent insertion. CONCLUSION: Bilateral VDAs presenting with SAH were safely treated with endovascular methods. However, endovascular treatment may be limited for VDAs with PICA origin involvement.

Objective Treatment of bilateral vertebral artery dissecting aneurysms presenting with subarachnoid hemorrhage remains challenging as bilateral deconstructive procedures may not be feasible. In this case series, we describe our approach to their management and review the pertinent literature. Method A retrospective review of our prospectively collected database on aneurysms was performed to identify all patients with acute subarachnoid hemorrhage in the setting of bilateral intradural vertebral artery dissections (VAD) encompassing a period from January 2000 and March 2012. Result Four patients (M/F = 2/2; mean age, 51.5 years) were identified. In two cases the site of rupture could be identified by angiographic and cross-sectional features; in these patients deconstructive treatment (proximal obliteration or trapping) of the ruptured site and reconstructive treatment of the unruptured site (using stents and coils) were performed. In the patients in whom the site of hemorrhage could not be determined, bilateral reconstructive treatment was performed. No treatment-related complications were encountered. Modified Rankin scale scores were 0–1 at discharge, and on follow-up (mean 63 months), no recurrence, in-stent thrombosis or new neurological deficits were encountered. Conclusion We believe that single-stage treatment in patients with bilateral VAD is indicated: If the site of hemorrhage can be determined, we prefer deconstructive treatment on the affected site and reconstructive treatment on the non-affected site to prevent increased hemodynamic stress on the unruptured but diseased wall. If the site of dissection cannot be determined, we prefer bilateral reconstructive treatment to avoid increasing hemodynamic stress on the potentially untreated acute hemorrhagic dissection.

Abstract BACKGROUND: The treatment of ruptured dissecting aneurysms of the intracranial vertebral artery (VA) with parent vessel preservation is a challenge for neurosurgeons and interventional neuroradiologists. OBJECTIVE: To propose an indication for flow-diverting treatment for reconstruction of a dissecting VA with acute subarachnoid hemorrhage. METHODS: Two male patients transferred after acute subarachnoid hemorrhage and dissecting aneurysm on the V4 segment of the dominant VA. An occlusion test was not performed because of their poor clinical state. A flow-diverting stent represented by the Pipeline embolization device was suggested to both patients. RESULTS: Three Pipeline embolization devices were deployed in each VA. One dissecting aneurysm was excluded immediately after 3 stents, and 1 patient had complete exclusion demonstrated at the 48-hour control. No morbidity directly related to the procedure was observed. No recanalization and no rebleeding occurred during the 3 months of follow-up. CONCLUSION: A flow-diverting stent may be considered an option to treat ruptured dissecting aneurysms of the VA, providing remodeling of the parent vessel and complete exclusion of the aneurysm.

✓ Seven cases of dissecting aneurysm of the vertebral artery, all appearing to be of fusiform type, are reported. Clinically, all seven cases initially showed symptoms of subarachnoid hemorrhage; however, three of these were associated with Wallenberg's syndrome. The characteristic angiographic findings in these cases were: 1) retention of contrast medium in the aneurysm; 2) the presence of a true (vertebral artery) and false (arterial wall) lumen in the late arterial and/or venous phase; and 3) irregular arterial narrowing proximal and/or distal to the aneurysm. Autopsy findings of one patient supported the angiographic findings. Recently, reports of fusiform aneurysms associated with subarachnoid hemorrhage have been increasing. As dissecting aneurysms are found in the fusiform group, it is very important to analyze serial angiograms in order to choose a method of surgical treatment.
