[Reno-coeliac steal phenomenon: the inferior phrenic and supra-renal arteries as collaterals for the coeliac trunk (author's transl)].

If the known collateral pathways for a stenosed or occluded coeliac trunk are not avialable whether for anatomical of haemodynamic reasons, a collateral circulation can be established through the suprarenal and inferior phrenic arteries to provide a significant flow. This is particularly so if the inferior phrenic artery arises from the coeliac trunk distal to the point of occlusion. The development of a reno-coeliac steal phenomenon or steal syndrome may then be expected, particularly if the main donor artery is a suprarenal branch arising from the renal artery.

[The collateral circulation for occlusion of the three unpaired abdominal arteries (author's transl)].

A fifty-two year old patient had only a short period of abdominal angina, despite occlusion of all three unpaired abdominal aortic branches. An extensive collateral system provided the circulation to the abdominal organs: intercostal arteries and adrenal vessels through the inferior phrenic artery for the coeliac trunk; arteries from the left iliac for the inferior mesenteric artery and through Riolan's arc (type II) for the superior mesenteric artery. Lumbar vessels provided a supply to the proximal territory of the superior mesenteric artery. In addition, it was possible to demonstrate connections between several lumbar arteries; several of these were also occluded proximally.

[Double and multiple carcinomas of the colon (author's transl)].

Double or multiple carcinomas of the colon represent approximately 4% of all colon carcinomas. They may arise spontaneously or occur as a result of some predisposing disease. It is necessary to distinguish between double or multiple carcinomas arising synchronously or in sequence. Diseases such as ulcerative colitis, colonic polyposis and adenomatous polyps are pre-disposing conditions whereas familial polyposis is pre-cancerous.

Ultrasonography versus clinical examination in evaluation of testicular tumors.

The diagnostic results of clinical examination and gray-scale ultrasonography for scrotal pathology were compared in 411 patients. Sensitivity and specificity of the clinical diagnosis of a testis tumor improved significantly with the use of ultrasonography. Criteria for the ultrasonographic diagnosis of a testicular tumor were evaluated. We had no false-negative ultrasonographic diagnoses, and they have rarely been reported in the literature. With ultrasonography, the number of false-positive clinical diagnoses was reduced from 11 to 5.

Staging of rectal carcinoma using MR double surface coil, MR endorectal coil, and intrarectal ultrasound: correlation with histopathologic findings.

OBJECTIVE: Our goal was assessment of the preoperative staging of rectal carcinoma with MR with double surface coil, MR with endorectal coil, and intrarectal ultrasound (IUS) as correlated with histopathologic findings. MATERIALS AND METHODS: Fifteen patients with rectal carcinoma had preoperative evaluation using intrarectal ultrasound (all 15 patients), MR with double surface coil alone (6 patients), and MR with double surface coil combined with endorectal surface coil (9 patients). The results of the preoperative staging were correlated with the histopathologic findings. RESULTS: IUS correctly staged the depth of bowel wall invasion in 10 of 15 patients, understaged 4, and overstaged 1. MRI correctly staged 10 of 15 patients. Without the endorectal surface coil, three of six were correct, and with endorectal surface coil seven of nine. MR with the endorectal surface coil is able to show the rectal wall in more detail than the double surface coil. CONCLUSION: Endorectal surface coil MRI provides increased detail of the rectal wall, leading to better delineation of its different layers. This may lead to better staging results than with other MR techniques. The results with endorectal MRI probably equal those of IUS for staging small tumors in the rectal wall. MR with the double surface coil gives additional information about tumor spread in more advanced cases.
