[CT-guided sympathicolysis in peripheral artery disease - Indications, patient selection and long-term results].

PURPOSE: Assessment of long-term results of CT-guided lumbar sympathicolysis (LSL) in advanced peripheral arterial vascular disease (pavd). Establishment of a suitable patient selection. PATIENTS AND METHODS: LSL was performed in 138 cases with Fontaine stages III (13 %) and IV (87 %). 250 consecutive patients were examined with a radionuclide perfusion study of the feet prior to and during peridural anaesthesia (PDA) in order to select suitable patients for LSL. LSL was not performed in patients with impaired perfusion under PDA (n = 112). Early and long-term results after one to five years were evaluated. RESULTS: In 79 % an initial improvement was found after LSL. After more than one year success was established in 38 %. 49 % of the cases had a progression of the disease. This is significantly better compared to a control group with conservative treatment and an initial improvement of 36 %. After more than one year only12 % revealed an improvement. In 82 % the disease was progressive. Diabetics showed also a positive response to LSL. CONCLUSION: LSL has a positive influence on the course of pvad in patients selected by radionuclide perfusion studies. Diabetes and angiographic findings do not play any first role in patient selection for LSL.

Current practice of temporary vena cava filter insertion: a multicenter registry.

PURPOSE: To evaluate the current practice of temporary vena cava filter placement and its complications. MATERIALS AND METHODS: A multicenter registry was conducted from May 1995 until May 1997 using a standardized questionnaire. One hundred eighty-eight patients were evaluated. Patient characteristics, filter indications, filter characteristics, and complications were registered. RESULTS: Deep vein thrombosis was proven in 95.2% of the patients. Main filter indication was thrombolysis therapy (53.1%). Average filter time was 5.4 days. An Antheor filter was inserted in 56.4%, a Guenther filter in 26.6%, and a Prolyser filter in 17.%. Transfemoral filter implantation was slightly preferred (54.8%). Four patients died of pulmonary embolism (PE) during filter protection. Major filter problems were filter thrombosis (16%) and filter dislocation (4.8%). When thrombus was found in or at the filter before explantation, additional thrombolysis was performed in 16.7%, additional filter implantation in 10%, and thrombus aspiration in 6.7%; 4.8% of filters were replaced with permanent filters. DISCUSSION: Temporary vena cava filters are placed to prevent PE in a defined patient population. Despite their presence, PEs still occur in a small percentage. Problems of filter thrombosis and dislocation have to be solved. CONCLUSION: The results of this multicenter registry support the need for innovative filter design, as well as a randomized, prospective study.
