Abstract
We report our experience with endovascular embolization using liquid coils. Twenty-two transarterial embolization procedures were performed with these coils in 20 patients with cerebrospinal vascular or neoplastic lesions. The coils were delivered into the target vessels under fluoroscopic monitoring through a microcatheter by manual injection and flushing with saline.
Subsequent surgical resections of embolized lesions were performed in 14 cases, and radiosurgery for two. Complete obliteration of the target vessels were accomplished in all cases without complications. Passage through the microcatheter and delivery of the coil was smooth. Proximal protrusion of the coil occurred during the procedure, and a combination of other embolic materials was necessary to completely occlude large vessels in 9 cases.
The embolized lesions were easily resected in the following neurosurgery. Liquid coils were safe and effective as an embolic material in use prior to surgery or radiosurgery.
