Results, complications, and technical nuances are reviewed.<\/jats:p><\/jats:sec>\n\nResults<\/jats:title>\nFourteen endovascular procedures were performed in 5 patients after EC-IC bypass for ruptured aneurysms in 4 patients and posterior circulation ischemia in 1 patient. In 2 patients, a saphenous vein graft (SVG) was used to bypass the common carotid artery (CCA) to the middle cerebral artery (MCA). One patient underwent a superficial temporal artery (STA)\u2013MCA bypass, and in 2 other patients the STA stump was connected to the intracranial circulation via an interposition SVG. The interval from surgery to endovascular intervention spanned 2\u201318 days; the indication was intracranial vasospasm in all patients. One case involved angioplasty of the proximal anastomosis on postoperative Day 14. All other interventions entailed proximal access through the bypass conduit for intraarterial infusion of vasodilators. Significant vasospasm of the STA itself was encountered in 2 patients during endovascular manipulation, and it was treated with intraarterial nitroglycerin. There were no cases of anastomotic disruption.<\/jats:p><\/jats:sec>\n\nConclusions<\/jats:title>\nEndovascular catheterization and intervention involving a recent EC-IC bypass is feasible. The main limitation in this series was catheter-induced vasospasm involving the STA. A vein graft may be the more appropriate option in patients with subarachnoid hemorrhage who may require subsequent endovascular intervention for vasospasm.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2011.8.jns11747","type":"journal-article","created":{"date-parts":[[2011,9,23]],"date-time":"2011-09-23T13:37:09Z","timestamp":1316785029000},"page":"201-207","source":"Crossref","is-referenced-by-count":9,"title":["Safety
