Transcatheter Embolization (transcatheter + embolization)
Selected AbstractsTechniques and Applications of Transcatheter Embolization Procedures in Pediatric CardiologyJOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 5 2003JAMES Y. SIM M.D. Transcatheter embolization of congenital or acquired superfluous vascular structure has become routine procedures performed by interventional pediatric cardiologists. Embolization procedure is often part of a collaborative effort with cardiac surgeons to palliate complex congenital heart defect, such as in embolizing aortopulmonary collateral arteries in patient with single ventricle physiology. In other cases, the procedure is the definitive treatment as in embolizing coronary artery fistula. Pediatric cardiologists performing embolization procedures should be familiar with available technologies as well as understand the underlying cardiac anatomy and pathophysiology. This article provides a comprehensive review of presently available embolization agents and technologies. Some of the technologies are used only by interventional radiologists but may be useful to pediatric cardiologists. Specific clinical applications in pediatric cardiology are also discussed with summary of current literature. With continue advancement in transcatheter technology and operator expertise, all unwanted vascular communication should be amenable to transcatheter embolization.

In the extremities they are usually associated with dermatological manifestations, such as angiodermatitis with a potential risk of torrential haemorrhage. Surgical resection is a morbid procedure. Transcatheter embolization and sclerotherapy is an attractive alternative to surgical resection. However, proper case selection is a prerequisite and may not be possible in all the cases. The case reported here is a paradigm of a complex and extensive vascular malformation with torrential haemorrhage where a unique therapeutic approach of radiation therapy was used as an alternative to morbid surgery after embolization and sclerotherapy failure.

Traditional embolization technique is to embolize the proper hepatic artery or the segmental hepatic artery by femoral approach using gelfoam pledgets. From 1997 to 2004, in 19 out of 96 embolizations, the embolization technique had to be modified because of tortuous conventional or aberrant hepatic vascular anatomy or parasitic supply to achieve successful embolization.
