Objective: To evaluate the technical success, safety and outcome of endovascular coiling procedure in intracranial aneurysms. Methods: From April 2003 to April 2009, 43 patients (23 males and 20 females), age range 11 to 70 years, mean age 46.67 ± 11.57 years were treated for intracranial aneurysms by detachable coil deployment at Radiology Department of Aga Khan University Hospital. Aneurysm rupture with subarachnoid haemorrhage was the cause of presentation in 39 patients while 4 patients were diagnosed with un-ruptured aneurysms. At time of presentation, grading of subarachnoid haemorrhage was done according to Hunt and Hess grading system. Eleven patients presented with Grade I haemorrhage, other 11 presented with grade II haemorrhage, 8 patients had grade III haemorrhage and 9 patients had grade IV haemorrhage. Preliminary diagnostic workup was performed by cross sectional imaging, CT angiography or digital substraction angiography. Coiling procedures were performed under general anaesthesia through femoral artery approach. Detachable platinum coils were densely packed in all aneurysms by endovascular technique. Patient files and radiology reports were retrospectively reviewed. Technical success and safety of the procedure were analyzed. Modified Rankin Score was used to determine clinical outcome. Score 0-2 represented good outcome, score 3-5: dependency (Can not attend own bodily needs and carry out daily activities without assistance) and score 6: death. Results: Aneurysm size ranged from 3mm - 22mm (mean size 8 mm ± 4). 74.4% aneurysms had narrow necks while 25.6% aneurysms were wide necked. Most common aneurysm site was anterior communicating artery. Technical success rate for endovascular intracranial aneurysm coiling was 95.3 % (n = 41). Major complication rate was 11.6 % (n = 5). Mortality rate was 2.3% (n = 1). 78 % patients showed good clinical outcome after coiling including 4 patients with un ruptured aneurysms (n = 32). Conclusion: Results of endovascular aneurysm coiling at our center showed high technical success rate (95.3%) and good short term clinical outcome in 78% patients (JPMA 60:638; 2010).
