Transcatheter embolization of pelvic vessels for control of intractable hemorrhage.

Transcatheter embolization for intractable hemorrhage from pelvic organs was performed in 46 patients. Advantages are discussed regarding different embolic materials, particle size, and embolization directed at branch vessels versus divisional arteries. An optimal approach for managing hemorrhage of different etiologies is developed, taking advantage of (a) selective embolization techniques, (b) pharmacologic manipulation of blood flow, and (c) the ability of embolic material to allow restitution of flow and/or continued collateral perfusion via the precapillary plexus.
