Abstract :

Carotid blow out syndrome (CBOS) is a catastrophic neurovascular emergency associated with a high morbidity and mortality (M&M). The main etiology of CBOS is: head and neck malignancies with tumor invasion, post radiation therapy of malignancies, and less common etiologies are: postoperative complications, inflammation, trauma, vasculitis, collagen diseases among others. The conventional surgical management is carotid artery and/or branch ligation or bypass, and is rather difficult and associated with significant M&M and could be ineffective in controlling the situation. At this time, the ideal management of this serious problem is the IR and INR endovascular: insertion of stents of different kinds (covered or uncovered, self-expanding or balloon-expandable) and/or embolization of the carotid or vertebral arteries or branches, with temporary or permanent agents and/or devices. A permanent or temporary success is expected with stent insertion and/or embolization, or both procedures combined. We have managed many patients, not considered ideal candidates for surgery, at least during the acute phase, with stents from different manufacturers, mostly covered. In addition, we have embolized some patients as well, and some other patients have had both methods. The procedures have been done in the IR suite by the IR, INR and surgeons as well, working in team, in a collaborative rather than in an adversarial manner. No major complications related to the procedures have been found. The patients have had a long-term or a temporary improvement in their condition. The emergent management of CBOS by stenting and/or embolization or both is a safe, effective and relatively easy procedure to temporarily manage these seriously ill patients. A longer follow up and many more patients studied are necessary to establish the definitive role of stenting and/or embolization in CBOS. In conclusion, the conventional surgical management of CBOS may be difficult and/or ineffective; therefore, the endovascular management is considered the first choice of therapy, at least for now, especially in clinically desperate situations.

He received his MD degree summa cum laude from the same San Marcos National University Medical School. He was a Resident in Radiology for 4 years at Thomas Jefferson University Medical Center in Philadelphia, 1967-71. He then became an Assistant Professor of Radiology and Director of Interventional Radiology at Albany Medical College, Albany, NY, 1974-77. Thereafter he moved to Virginia Commonwealth University, in Richmond, VA, where he became Associate Professor of Radiology and Director of Interventional Radiology and eventually became Professor of Radiology and Professor of Surgery, at the same university from 1985 till 2010. Thereafter, he was named one of the few Professor Emeritus of Radiology and Surgery, all at the same Virginia Commonwealth University in 2010 till now. He has published more than 100 articles in peer reviewed journals, about 400 scientific posters and electronic exhibits all over the country and the world, and about 200 abstracts, 4 books, many chapters in books, and about 200 papers presented at meetings, at the local, national, and worldwide level.
