Subcutaneous ports in the radiology suite: an effective and safe procedure for care in cancer patients.

The purpose of the study is to present our experience and compare the results of the three types of ports used as a central venous access and performed in the radiology suite. Between March 1989 and November 1993 we performed 288 implantations (100 Implantofix Seldinger, 100 plastic Hickman port, and 88 stainless steel Port-a-cath) for chemotherapeutic treatment on the same number of patients diagnosed as having cancer. In all cases access was obtained via a subclavian vein (the left one in 185 cases and the right one in 103). All the system ports were implanted in the radiology suite. In all cases the procedure was successfully performed. Complications occurred in 26.3% of cases, most notably thrombosis in 13 cases (4.5%) and infection in 12 cases (4.1%). Duration of the port systems placement varied between 17 and 1467 days (a mean of 315 days). A total of 133 systems have been removed to date, 80 (60.%) due to termination of chemotherapy, and 53(40%) for treatment of complications. Significant differences (complications and port duration time) were not observed between the three types of reservoir used. Subcutaneous ports are safe, comfortable, and effective devices for central venous access.

[Treatment of acute colorectal obstructions by implantation of expandable metal prosthesis].

PURPOSE: To determine the efficacy of colorectal stents implanted through the anus for the treatment of acute intestinal occlusion before elective surgery. MATERIAL AND METHODS: 25 patients (3 females and 22 males) with a mean age of 62.5 years (range: 49-94), were diagnosed of lower intestinal occlusion due to neoplasm. In all cases, an expandable metallic stent was implanted through the anus during the first 24 h. X-ray studies, tumoral staging and surgical preparation were performed in all cases. RESULTS: Implantation of stent was successful in 23 patients (92%). Clinical improvement of intestinal occlusion was observed in 24 hours. Criteria of no-resectability were found in five patients (20%). The remaining patients (18 cases) were treated by tumoral resection and end-to-end anastomosis an average of 8.6 days there after. No complications were observed and the patients were discharged 8.3 days after surgery. CONCLUSION: The implantation of colorectal stents before elective surgery constitutes a good alternative to surgery in the acute lower intestinal occlusion (left colon and rectum-sigmoid emergency).

[The percutaneous retrieval of vascular foreign bodies].

Intravascular foreign bodies can cause significant complications: thrombosis, pulmonary and peripheral embolism, etc. It is therefore necessary to remove them, and this may be accomplished through surgery or by means of radiotherapy techniques. In the past year we have percutaneously extracted three foreign bodies originating in vascular access pathways.
