[Angiographic and morphological findings in testis tumors (author's transl)]

The arterial supply of testicular tumors is compared to that of normal testes. Data were collected from comparative angiographic and morphologic studies of 21 surgical and autopsy specimens. The arterial vascularization of seminomas is rather poorly developed, newly formed vessels show only minor differences of caliber. Non-seminomatous testicular tumors show a strongly irregular pattern of arterial branching with bends, variations of caliber, irregular contours, completely avascular areas, and extravasation of contrast medium. Depending on the size of tumors, the original testicular arteries are displaced and compressed more or less strongly. Angiographic findings are correlated with morphologic finding. The relevance of different patterns of vascularization for therapeutic considerations is discussed.
