Case 5; a 54-year-old man with subarachnoid hemorrhage (SAH). A : The left internal carotid artery (ICA) angiogram shows the aneurysm before treatment. B : 3D reconstruction image shows a wide-necked posterior communicating artery (PCoA) aneurysm (neck×height×width×length : 4.6×4.3×5.3×6.8 mm). C : Two microcatheters are positioned within the aneurysm. One has a 90° angled distal tip and the other has a J-shaped distal tip. D : First coil (360° Guglielmi detachable coil 4×8 mm) being deployed. E : Second coil (360° Guglielmi detachable coil 3×6 mm) being deployed via another microcatheter. F : Immediately after treatment, a right ICA angiography shows no contrast dye filling of the aneurysm neck or dome, but the patient died of severe vasospasm on the 10th day after coil embolization.
