Abstract:
Objective To investigate the method of handmade microwire lasso device for the management of coil migration during intracranial aneurysm embolization. Methods Two migration coils were removed from intracranial arteries using handmade microwire lasso rings. The first coil prolapsed completely from an aneurysm sac and flowed to the middle cerebral artery M2 segment. The second coil partially prolapsed out into a parent artery. The microwire lasso device was made of 4-0 silk thread and fixed using 0. 36 mm (0. 014 inch)microwire and 0. 43 mm (0. 017 inch)microcatheter. Results After removing 2 migration coils from intracranial arteries,angiography did not reveal vascular injury and thrombosis. There was no aneurysm rupture. After awaking from anesthesia,the patient did not have neurological deficit. The patient was followed up for 3 months after procedure. MR angiography confirmed the patency of related arteries. Conclusion The handmade microwire lasso device for the management of coil migration in the process of aneurysm embolization is a simple,effective,and economical method.
