Longterm patency of infrainguinal bypass procedures may be established on the basis of clinical evaluation and ankle pressure measurements. With the aim of assessing whether these parameters could predict grafts at risk for occlusion, we identified 24 patients in whom the bypass had occluded between 3 and 12 months postoperatively, but following at least one follow-up. These patients were compared with a control group consisting of further 24 patients operated on during the same period, but in whom the bypass was patent. Prior to graft occlusion only nine (39%) patients had complained of claudication, and a significant drop in ankle pressure was demonstrated in seven (29%) patients. These figures were significantly higher than the one (4%) patient in the control group who complained of claudication and the other (4%) patient who developed a drop in ankle pressure (p < 0.02 and 0.05, respectively). Graft surveillance based on patients' history and ankle pressure measurements are insufficient parameters for identification of grafts at risk for occlusion. However, the occurrence of claudication and/or a significant drop in ankle pressures are associated with a high incidence of graft thrombosis.
A 55 year old patient 3 years after gastric resection (Billroth II) has got gastric outlet stenosis. Half year ago was established a tumour recidive, that the time of reoperation was inoperable. Under endoscopic and radiological control we have introduced and placed a 19 mm diameter, 4 cm long balloon expandable tantalum stent (Strecker stent). The gastric passage has normalised and after 6 month the patient is symptom free.
D-Glucose 3- and 6-[sodium 2-(perfluoro-hexyl or -octyl)ethyl phosphates) have been synthesized by condensation of 1,2,3,4,-tetra-O-acetyl-beta-D-glucopyranose and 1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose with 2-(perfluoroalkyl)ethylphosphoroditriazolides followed by O-deacetylation or deacetalation. The structures of the compounds were established on the basis of 1H-, 19F-, 31P-, and 13C-NMR data. These salts display strong surface activities and appear to have good biocompatibility.
