Assessment of detachable platinum coils and balloons for treatment of cerebral aneurysms in patients with subarachnoid haemorrhage

Background: Aneurysmal Subarachnoid Hemorrhage (SAH) has a 30-day mortality rate of 45%, with approximately half of the survivors sustaining irreversible brain damage. Objective: To assess the efficacy of Endovascular Treatment (EVT) using detachable coils to prevent rebleeding and its complications. Methods: Our study included 24 patients with H&H scale (I-IV), those patients had 25 saccular aneurysms for whom endovascular coiling was done. Fourteen males and 10 females were involved. 33.3% had (H & H scale I-II), 54.2% had (H & H scale III) while 12.5% were (H & H scale IV). Simple coiling was done in 68% of the aneurysms, stent-assisted coiling for wide neck aneurysms was used in 6 aneurysms while balloon remodeling was done in 8% of the treated aneurysms. Results: Total occlusion of the aneurysms was achieved in 92%, a neck remnant was left in 4% and only 4% showed incomplete occlusion and needed a second EVT session. We faced only one clinical complication during the procedure due to branch occlusion (4%). None of the aneurysms perforated. The outcome as assessed by mRS was good 6 months after occlusion. No recanalization appeared in 91.4 % of those aneurysms while stable neck remnant appeared in 4.3% of the treated aneurysms and 4.3% showed partial recanalization with follow up after 6 months. After 6 months no rebleeding. Conclusion endovascular coil treatment of ruptured aneurysms is an effective and safe technique in the occlusion of cerebral aneurysms from either anterior or posterior circulation.
