Stroke from Delayed Embolization of Polymerized Glue Following Percutaneous Direct Injection of a Carotid Body Tumor
نویسندگان
چکیده
A 52-year-old male with right carotid body tumor underwent direct percutaneous glue (n-butylcyanoacrylate [NBCA]) embolization. Several hours later, he developed left hemiparesis from embolization of the polymerized glue cast. Migration of glue during percutaneous tumor embolization is presumed to occur only in the liquid state, which may lead to stroke or cranial nerve deficits. To the best of our knowledge, this is the first report of delayed glue embolization from a treated hypervascular tumor of the head and neck.

Comment on: Current concepts in the management of carotid body tumours.
Preoperative embolization has played a major role in the devascularization of carotid body tumours prior to surgery. There are two currently approved methods to achieve this, which is a superselective transarterial endovascular embolization and a direct percutaneous injection of embolic materials . Superselective transarterial endovascular embolization has potential limitations especially in le...

Substantial intraoperative bleeding during surgical removal of carotid body tumor may be a major problem in the management of these highly vascularized tumors. Traditional preoperative embolization via a transarterial access has proved effective but is often limited by complex vascular anatomy and small feeding vessels that is difficult to catheterize. We report two cases of carotid body tumor ...

In this report of 20 patients with 24 carotid body tumors which is the largest series reported so far from Iran, we have evaluated the various characteristics of this relatively rare tumor in our population and compared our results with that of the literature. Although the prevalence of the tumor is cited to be equal among both sexes, we found a female to male ratio of 2.3 to I, as 14 of o...
