<meta name="DC.Description" content="BACKGROUND AND PURPOSE: The purpose of this study was to report the midterm clinical and angiographic results of coiling of very large (&gt;15 mm) and giant basilar tip aneurysms.

MATERIALS AND METHODS: Between January 1995 and October 2005, 44 very large and giant basilar tip aneurysms in 44 patients were coiled. There were 13 men (30%) and 31 women (70%) with a mean age of 51.4 years (median, 51 years; range, 34–72 years). Mean aneurysm size was 19.6 mm (range, 15–30 mm). Of 44 aneurysms, 33 (75%) had ruptured. Of 11 unruptured basilar tip aneurysms, 7 were incidentally discovered, 1 was additional to another ruptured aneurysm, and 3 were symptomatic by mass effect.

RESULTS: Procedural mortality was 2/44 (4.6%, 95% confidence interval (CI), 0.4%–16%) and morbidity 1/44 (2.3%, 95% CI, 0.01%–13%). Of 33 patients with ruptured aneurysms, mean clinical follow-up was 5.2 years (range, 0.5–11.5 years). Two patients had a rebleeding from the coiled basilar tip aneurysm leading to death in 1 patient and to dependency in the other patient (annual rebleeding rate, 1.1%) One other patient died 2 years later of progressive brain stem compression. Mean angiographic follow-up in 41 of 42 surviving patients was 3.1 years. Nineteen aneurysms reopened and were coiled for a second time. Of these, 9 repeatedly reopened with time and were repeatedly coiled up to 6 times. Additional treatments were without complications.

CONCLUSION: Coiling of very large and giant basilar tip aneurysms is associated with reasonably low morbidity. Although additional treatment during follow-up is frequently necessary, rebleeding is uncommon." />

There were 13 men (30%) and 31 women (70%) with a mean age of 51.4 years (median, 51 years; range, 34–72 years). Mean aneurysm size was 19.6 mm (range, 15–30 mm). Of 44 aneurysms, 33 (75%) had ruptured. Of 11 unruptured basilar tip aneurysms, 7 were incidentally discovered, 1 was additional to another ruptured aneurysm, and 3 were symptomatic by mass effect.</p><p id="p-3"><strong>RESULTS:</strong> Procedural mortality was 2/44 (4.6%, 95% confidence interval (CI), 0.4%–16%) and morbidity 1/44 (2.3%, 95% CI, 0.01%–13%). Of 33 patients with ruptured aneurysms, mean clinical follow-up was 5.2 years (range, 0.5–11.5 years). Two patients had a rebleeding from the coiled basilar tip aneurysm leading to death in 1 patient and to dependency in the other patient (annual rebleeding rate, 1.1%) One other patient died 2 years later of progressive brain stem compression. Mean angiographic follow-up in 41 of 42 surviving patients was 3.1 years. Nineteen aneurysms reopened and were coiled for a second time. Of these, 9 repeatedly reopened with time and were repeatedly coiled up to 6 times. Additional treatments were without complications.</p><p id="p-4"><strong>CONCLUSION:</strong> Coiling of very large and giant basilar tip aneurysms is associated with reasonably low morbidity. Although additional treatment during follow-up is frequently necessary, rebleeding is uncommon.</p></div><ul class="copyright-statement"><li class="fn" id="copyright-statement-1">Copyright © American Society of Neuroradiology</li></ul><span class="highwire-journal-article-marker-end"></span></div><span class="related-urls"></span></div><a href="http://ajnr-stage2.stage.highwire.org/content/28/7/1405.full" class="hw-link hw-link-article-full-text" data-icon-position="" data-hide-link-title="0">View Full Text</a></div>  </div>
