[Clinical experiences with ultrasound-reflection computerized tomography of the breast].

Ultrasound-reflection computed tomography (URCT) of the breast can produce astonishingly detailed high resolution images of the breast, particularly in the coronal plane. In some cases it improves the demonstration of the structure of scirrhous carcinomas in this plane. On the other hand, some valuable diagnostic features known from conventional breast sonography, such as acoustic shadows and hyper-reflective area (cysts) are suppressed on URCT images and are not readily recognized. Despite individual outstanding images, a comparison carried out on 100 patients showed no advantages of URCT compared with high-resolution real-time sonography.

Percutaneous transluminal treatment of varicoceles: where to occlude the internal spermatic vein.

Percutaneous transluminal sclerotherapy is an accepted treatment for varicoceles. It is administered by applying a liquid sclerosing agent to the internal spermatic vein. However, the optimal site for the placement of the occlusive material has not been evaluated previously. Therefore, the success rate of sclerotherapy was determined in two groups of patients. In the first group (34 patients), the liquid agent was applied in the cranial part of the internal spermatic vein; in the second group (113 patients), the agent was applied in the caudal part of the vessel at the level of the inguinal ring. The success rate determined 3 months after therapy by telethermography was significantly higher after treatment in the caudal part (82%) than in the cranial part (68%) of the vessel. Sclerotherapy at the level of the inguinal ring appears to be superior to therapy in the cranial part of the internal spermatic vein.

[Noninvasive imaging procedures in the diagnosis and therapy control of varicoceles. I: Sonography and thermography in the diagnosis of varicoceles].

69 patients with clinically suspected varicoceles were examined thermographically and sonographically prior to testicular phlebography. The combination of sonography and thermography permitted precise differentiation into normal findings (7%), left-sided varicoceles (86%) and bilateral varicoceles (7%). Thermography was advantageous with an accuracy of 97.3%. Sonography had an accuracy of 90.5%. No clear correlation was found between varicocele size and degree of hyperthermia. The combination of sonography and thermography affords a high degree of accuracy in the diagnosis of varicoceles, including subclinical and infantile varicoceles.

Varicoceles: combined sonography and thermography in diagnosis and posttherapeutic evaluation.

One hundred eighteen patients with clinically suspected varicocele were examined with thermography and sonography before phlebography of the internal spermatic vein (ISV). The combination of sonography and thermography led to an exact differentiation among eight patients with normal findings (6.8%), 103 with left-sided varicoceles (87.3%), six with bilateral varicoceles (5.1%), and one with a right-sided varicocele (0.85%). The accuracy of thermography was 98.4% and of sonography, 92.7%. With sonography, venous dilatation was detected when the patients were upright and the Valsalva maneuver was being performed. Thermography was more sensitive than sonography in detecting persistent varicocele in 63 patients reexamined after sclerotherapy. Sclerotherapy within the inguinal segment of the ISV gave better results (82.9%) than that within the proximal segment (77.3%).

Minimally invasive catheter implantation for regional chemotherapy of the liver: a new percutaneous transsubclavian approach.

PURPOSE: Development of a percutaneously implantable catheter system for regional chemotherapy of liver metastases and its application in patients with surgically implanted but dislocated catheters. METHODS: Thirty-three patients with liver metastases of colorectal tumors were submitted to percutaneous puncture of the subclavian artery and insertion of a catheter whose tip was placed in the proper hepatic artery and whose end was subcutaneously connected with an infusion pump. RESULTS: The mean duration of therapy via the percutaneously inserted catheter was 27 weeks (+/-14 weeks). The most frequent complication was disconnection of the therapy catheter from the tube of the infusion pump. Eighty percent of all complications were corrected by reintervention. The therapy drop-out rate due to catheter-associated complications was 9%. CONCLUSION: Percutaneous insertion of a catheter for regional chemotherapy of the liver is a relatively uncomplicated method with high patient acceptance and simple access for reintervention.
