The anatomic structure of the vascular supply of the pelvis has long been the subject of study. Progress in angiography rendered it a valu- able diagnostic aid. Nevertheless, angiography is finding new applica- tions in combination with the technique of superselective catheteriza- tion, opening the way for interventional angiography. Remarkable as this may prove, one must not overlook the difficulties involved, most of which essentially result from insufficient knowledge of the anatomic structure concerned: the pelvic arteries are particularly pro b- lema tic owing to their complexity and multiple variations. For this reason we here attempt to chart precisely the course of each artery supplying the pelvis and to provide a synthetic study of the different vascular territories. The book is completed by some pathologic exam- ples which illustrate the sometimes very important role of embolization in therapy.
