The use of micro-coils in obstructing anterior communicating artery aneurysms：evaluation of its effect / 介入放射学杂志

ABSTRACT

Objective To evaluate the safety and effect of the use of micro coils in endovascular embolization of anterior communicating artery aneurysms. Methods The clinical data of 27 consecutive patients with anterior communicating artery aneurysm, who were admitted to Yancheng Municipal Third People’s Hospital to receive endovascular embolization treatment with micro coils, were retrospectively analyzed. One patient had multiple anterior communicating artery aneurysms. The efficacy and safety of endovascular micro-coil embolization of anterior communicating artery aneurysm were evaluated by the occlusion rate of aneurysm, the prognosis of the patients, the complications, the neurological function, etc. Results Successful embolization treatment of anterior communicating artery aneurysm was achieved in all 27 patients. Dual catheter technique was employed in 3 patients, stent-assisted technique was used in 3 patients, and the technical success rate was 100%. Dense embolization was obtained in 21 patients, and residual aneurysm neck was observed in 6 patients. The unobstructed parent artery was reserved in all patients, no hemorrhage due to ruptured aneurysm or dropping of steel coil was found. One patient developed recurrent hemorrhage and died two days later. Mild recurrence was seen in one patient six months after the treatment. The modified Rankin scal (mRS) score showed that 0-1 point was seen in 24 patients, 2 points in one patient, and 4 point in one patient. Conclusion The anterior communicating artery aneurysm can be safely and effectively cured when appropriate endovascular embolization technique is used.
