Abstract

Background: N-butyl-2-cyanoacrylate (NBCA) has been used for vascular malformations since the 1980s; however, few studies have looked at applications, procedural techniques, and outcome throughout many institutions. Herein, we review applications, procedural techniques, previous literature, and outcomes for the use of NBCA specifically through percutaneous technique in treating head and neck vascular pathology.

Methods: An extensive literature review using PubMed database with published literature containing "N-butyl-2-cyanoacrylate embolization," was performed. No date restrictions were used. Cross-checking of articles was conducted to exclude duplicate articles. The articles were screened for their full text and English language availability. We finalized those articles pertaining to the topic.

Results: The search yielded 1124 related articles. When comparing surgical resection to embolization with NBCA for cerebral AVMs, complications were similar in both groups and included hemorrhage (15%), residual AVM (6%), and cerebrospinal fluid leak (3%). Their mortality rate was 3% in both groups. Preoperative percutaneous embolization does show improved surgical outcomes.

Conclusion: NBCA is a fast-acting liquid embolic material used in the treatment of a variety of vascular malformations and lesions of the head and neck. Investigations surrounding the use of NBCA injections as a new alternative embolic agent began in the 1980's. Administration of NBCA has been shown to be useful in minimizing intraoperative blood loss and controlling acute hemorrhage. Performing percutaneous embolization with NBCA provides a successful alternative for surgeons when transcatheter embolization techniques may prove to be too difficult to perform. Embolization using NBCA will continue to play in integral role in the treatment of malignant lesions and vascular malformations. Continued research is warranted to improve safety, outcomes, and further develop clinical applications of NBCA.

Keywords: Arteriovenous malformation; Embolization; N-butyl-2-cyanoacrylate; Obliteration.
