Complications of 4181 cerebral angiographies performed from 1973 to 1978 in 2365 patients were analysed. In 13,6% of the patients temporary complications could be observed. In 3,1% temporary neurologic-psychiatric complications occurred, most of them in patients of younger age and in the presence of diffuse cerebrovasuclar disease. There was a permanent damage in 0,21%.

OBJECTIVE: Various studies have shown the benefit of extracorporal shock wave therapy (ESWT) in the treatment of soft tissue pathologies. The aim of this prospective study was to compare the results of ESWT with the operative treatment for achilleus tendopathy. Furthermore mechanical effects of the shock waves on the achilleus tendon were analysed by an in-vitro model. METHOD: The achilleus tendons of common pigs treated with 1500 impulses twice using an energy varying from 0.23 - 0.54 mJ/mm (2) were histologically examined. The clinical results of two patient groups of which the first (n = 28) was treated with 2000 impulses (0.23 mJ/mm (2)) once and the second (n = 26) underwent surgery for achilleus tendopathy were compared. RESULTS: The in-vitro model demonstrated that an EFD of 0.42 and 0.54 mJ/mm (2) can lead to tendon lesions. One year follow-up showed good and excellent results in 69 % and satisfactory results in 15 % of the operated group and good and excellent results in 29 % and satisfactory results in 43 % of the ESWT group. We could show a time-dependent effect of the shock wave treatment on the clinical outcome. CONCLUSIONS: Follow-ups show acceptable results with little side effects when an energy flow density (EFD) under 0.23 mJ/mm (2) is used. ESWT offers a non-invasive therapeutic concept that can seriously be contemplated before operative treatment, but lower success rates in comparison to the operative results can be expected.
The complications of 6,698 cerebral angiographies performed from 1979 to 1985 in 2,503 patients were analysed. In 5.24% of the patients (1.95% of the angiopathies) temporary complications could be observed. Temporary neurologic-psychiatric complications occurred in 1.96% of the patients (0.73% of the angiographies), most of them in middle-aged patients and in the presence in the presence of diffuse cerebrovascular disease. In 0.12% of the patients (0.05% of the angiographies) a permanent damage was recorded.
