“…A variety of angiographic techniques for the examination of the retroperitoneum have been proposed. Abdominal (flush) aortography is, however, the basic examination recommended by most authors (Lowman et al, 1971). Selective angiography of various arteries should be considered thereafter.…”

“…If the tumour is supplied by lumbar or intercostal arteries, the mass is usually situated in the retroperitoneum. If, on the other hand, the tumour is supplied either by the coeliac or inferior or superior mesenteric arteries the mass may be intraperitoneal (Lowman et al, 1971). A tumour situated in the anterior part of the retroperitoneum, however, will tend to receive its supply from the coeliac or mesenteric arteries (Kahn, 1971).…”

“…Only a part of the retroperitoneal tumours can be reliably diagnosed preoperatively by conventional radiological methods such as plain films, urography, and barium studies. In the last decade, a number of reports have stressed the importance of abdominal aortography and selective angiography of the branches supplying the retroperitoneum (Lowman et al, 1971;Kahn, 1971). Much progress has been made since crosssectional abdominal imaging with ultrasonography (Leopold and Asher, 1972) and CT (computerized axial tomography) (Stephens et al, 1977) were introduced.…”
Fifteen patients with retroperitoneal sarcoma were examined by angiography. Preoperative abdominal ultrasonography was performed in nine of them. Ultrasonography demonstrated in all nine cases a solid mass with characteristic echo-pattern with an echo-rich central area and an echo-poor periphery. Angiography demonstrated an avascular mass in one case, a hypovascular in four, and a hypervascular in ten cases. The techniques of both methods are discussed. The value of ultrasonography as a diagnostic procedure at the time of initial evaluation and angiography as an important diagnostic tool for localization of the mass and for achievement of anatomical details important for surgery is stressed.

“…Angiography carried out in a series of 30 retroperitoneal masses showed that the majority derived their blood supply from the lumbar vessels, and their visualization has proved to be highly useful in the localization and differentiation of intraabdominal and retroperitoneal masses. Stretching and hypertrophy of the supply arteries may be seen, and a parasitic supply arising from the lumbar arteries indicates retroperitoneal involvement (Lowman et al, 1972).…”

Two cases of primary retroperitoneal leiomyosarcoma presenting with obstructive uropathy which were successfully treated by surgical excision are reported. The classification of primary retroperitoneal tumours and their symptomatology, treatment and prognosis are discussed in detail based on a review of the literature and the current experience of treating these tumours by combination therapy. It is felt that with advances in the diagnosis and therapy the prognosis is likely to improve.
“…Mit Hilfe der selektiven Arteriographie werden Erweiterungen der tumorversorgenden Gef£1~e, Gef£Barrosionen, unregelm~l~ige, lakunen~hnliche Kontrastmitteldepots und arterioven6se Gisteln nachgewiesen [3,4,7,9,13,17].…”
Summary. Even when a tumor is detected with the aid of the methods of examination described, the differential diagnosis remains very difficult [10].It is easier for the radiologist to evaluate diagnostic criteria if he is familiar with the case history and the results of clinical examinations, and knowledge of the possible diagnoses allows the surgeon to institute examinations whose results will have an important bearing on his choice of surgical technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
