  • Purpose: To provide follow-up data on endovascular intervention for venous stenoses in the pelvis.Methods: Between 1985 and 1995, 35 patients presented with 42 stenoses of the pelvic veins after operative thrombectomy and creation of an arteriovenous fistula, combined with intraoperative venous angioscopy. All patients underwent angioplasty and, if unsuccessful, percutaneous insertion of an endovascular stent (n = 7).Results: Angioplasty with and without endovascular stenting was technically successful in 34 of 35 patients (97%). Average length of the stenoses was 20.6 mm (range 10-90 mm), average diameter before dilation 4.1 mm (range 2-6 mm), and average diameter after dilation 10.1 mmmore » (range 5-18 mm). Intraoperative angioscopy showed pathologic findings (intimal laceration or residual thrombotic material) in 14 patients. After an average follow-up period of 4.13 years, 24 (69%) patients had patent veins. The difference in the primary patency rate between patients with angioscopically abnormal veins (6 of 14 patients, corresponding to a patency rate of 43%) and patients with angioscopically normal veins after thrombectomy (18 of 21 patients, corresponding to a patency rate of 86%) was statistically significant (p < 0.01, log rank test).Conclusions: Percutaneous transluminal angioplasty and/or stenting are good treatment modalities for pelvic vein stenosis following surgical thrombectomy. Angioscopically abnormal veins have a poorer long-term patency, regardless of the type of intervention.« less
  • Starting originally from [NEt{sub 4}]{sub 2}[ReBr{sub 3}] (1), the three novel complexes [NEt{sub 4}][ReBr{sub 2}(PTA)(CO){sub 3}] (2), [ReBr(PTA){sub 2}(CO){sub 3}] (3a), and [Re(PTA){sub 3}(CO){sub 3}]PF{sub 6} (4) (PTA = 1,3,5-triaza-7-phosphaadamantane) were prepared and characterized by IR, {sup 1}H, {sup 13}C, and {sup 31}P NMR spectroscopy and X-ray crystallography. These complexes are the first representatives of mixed carbonyl/PTA complexes of an element of the manganese row. All substitution reactions have been performed under aerobic conditions at ambient temperature and the yields were in all the cases high. The disubstituted complex was isolated as the neutral species 3a and as the dicationicmore » species [ReBr(PTAH){sub 2}(CO){sub 3}]Br{sub 2}, 3b, which is protonated at one amine group of each of the two PTA ligands. The substitution reaction leading to the formation of 3a was performed in H{sub 2}O, methanol and DMSO/methanol (4:1) and the reaction was followed using {sup 31}PNMR techniques. These experiments revealed that the number and concentration of intermediate species during the substitution reaction are strongly dependent on the solvent system. Furthermore due to a completely different solubility behavior of 3a and 3b, a fully reversible phase transfer of the disubstituted complex from the organic (THF) to the aqueous layer (2 M NaBr) and back could be induced by simply changing the pH of the aqueous phase. In the {sup 31}P NMR experiment, the existence of the monoprotonated species [ReBr(PTA)(PTAH)(CO){sub 3}]Br (3c) could also be detected. X-ray data for the complexes are given.« less
  • We report a 73-year-old man with recurrent variceal bleeding due to portal hypertension caused by multiple intrahepatic arterio-portal venous fistulas, which were successfully occluded by embolization with n-butyl cyanoacrylate and micro-coils.
  • Aim. To evaluate the technical success and patency rates following primary cutting balloon angioplasty for venous stenoses in native dialysis fistulas. Methods. Forty-one patients (26 men, 15 women; age range 26-82 years, average age 59 years) underwent 50 (repeat procedures in 9 patients) primary cutting balloon (PCB) angioplasty procedures in three institutions by three primary operators. The indication was primary stenosis in 21 patients, recurrent lesions in 15, and immature fistulas in 5. A PCB was used alone in 17 cases, but was followed by a larger standard balloon in 33 cases. Follow-up included ultrasound, flow analysis and urea reductionmore » ratio, and ranged from 2 to 30 months (mean 14 months). Results. The technical success rate was 98%. All procedures were relatively painless. Two PCBs burst and 4 leaked, but without causing any morbidity. Nineteen fistulas were still working at last follow-up. Primary patency rates at 6, 12, and 24 months using Kaplan-Meier analysis were 88%, 73%, and 34%, respectively, and the primary assisted patencies were 90%, 75%, and 50%, respectively. Conclusion. PCB angioplasty has high technical success and low complication rates. The long-term patency rates are favorable for PCB angioplasty and compare favorably with other series.« less
  • We retrospectively evaluated the usefulness of both arterial and venous access with the pull-through technique in endovascular treatment of totally occluded Brescia-Cimino fistulas. We treated 26 patients (17 men, 9 women; age range 43-82 years, mean age 66 years) with occluded Brescia-Cimino fistulas. First, the occluded segment was traversed from the antegrade brachial arterial access using a microcatheter-guidewire system. Second, the vein was retrogradely punctured after confirmation of all diseased segments, and a 0.014- or 0.016-inch guidewire was pulled through the venous access when the occluded segment was long. All interventions including thrombolysis, thromboaspiration, angioplasty, and stent placement were performedmore » via the venous access. The occlusion was successfully crossed via the brachial arterial access in 23 patients (88%). In 2 patients it was done from the venous approach. In the remaining patient it was not possible to traverse the occluded segment. The pull-through technique was successful in all 19 attempts. Clinical success was achieved in 96%, the primary patency rates at 6, 12, and 18 months were 83%, 78%, and 69%, the primary assisted patency rates were 92%, 92%, and 72%, and the secondary patency rates were 92%, 92%, and 92%, respectively. Minor complications in 5 patients included venous perforation in 2 (8%), venous rupture in 1 (4%), and regional hematoma in 2 (8%). Our study suggests that endovascular treatments with both arterial and venous access using the pull-through technique are highly effective in restoring function in totally occluded Brescia-Cimino fistulas.« less
