- OBJECTIVES: To test the hypothesis that long-term postoperative dalteparin (Fragmin), Pharmacia Corp) treatment improves primary patency of peripheral arterial bypass grafts (PABG) in lower limb ischemia patients on acetylsalicylic acid (ASA) treatment. DESIGN: Prospective randomised double blind multicenter study. MATERIALS AND METHODS: Using a computer algorithm 284 patients with lower limb ischemia, most with pre-operative ischemic ulceration or partial gangrene, from 12 hospitals were randomised, after PABG, to 5000 IU dalteparin or placebo injections once daily for 3 months. All patients received 75 mg of ASA daily for 12 months. Graft patency was assessed at 1, 3 and 12 months. RESULTS: At 1 year, 42 patients had died or were lost to follow-up. Compliance with the injection schedule was 80%. Primary patency rate, in the dalteparin versus the control group, respectively, was 83 versus 80% (n.s.) at 3 months and 59% for both groups at 12 months. Major complication rates and cardiovascular morbidity were not different between the two groups. CONCLUSIONS: In patients on ASA treatment, long-term postoperative dalteparin treatment did not improve patency after peripheral artery bypass grafting. Therefore, low molecular weight heparin treatment cannot be recommended for routine use after bypass surgery for critical lower limb ischemia.

- Morphological properties of skeletal muscle were compared between wrist flexors and extensors within the same children (n = 8, six females, two males; age range 4 to 9y, median age 7 y) with wrist muscle imbalance secondary to spastic cerebral palsy (CP). Five patients had hemiplegic CP, two diplegic CP, and one patient had tetraplegic CP. Muscle biopsies were taken during either tendon transfer or tendon lengthening procedures. Analyses included distribution of muscle fibre types, fibre sizes, and expression of developmental myosins. Extensor fibre area was significantly greater than flexor fibre area for type 2A fibres and type 2B fibres but not for type 1 fibres. Coefficient of variation (CV) of fibre size for all three fibre types was greater for flexors compared with extensors. The greatest CV was observed for the type 2A fibres in flexors (39.5 [3.6%]). A wide variation was observed for expression of developmental myosin with the magnitude of the expression being greater, but not statistically significant, in flexors compared with extensors (5.4/mm2 vs 0.53/mm2). These data demonstrate that significant secondary myopathy of wrist flexor muscles results from CP.
