The effectiveness of prophylaxis of thromboembolism either by acetyl-salicylic-acid (ASA) 0.5 g + dihydroergotamin (DHE) 2.5 mg three times a day or by Heparin 5000 IU + 0.5 mg DHE (HDHE) three times a day was compared in 404 patients, elder than 55 years, with fractures close by the hip joint. Effectiveness was proved daily clinical controls, perfusion scintigraphy on the day after admission, the fourth postoperative day and the day before discharge and by autopsy of the died patients. Clinical manifest thrombosis were seen on the operated legs in the HDHE-group in 7.6% of the patients, in ASA-DHE-group in 15.6%, on the not operated leg under prophylaxis by HDHE in 3.8%, by ASA-DHE in 4.1% of the patients. Increased postoperative bleeding could be found under HDHE in 16.1% of the patients, under ASA-DHE in 9.3% of the patients, wound haematoma in 9.5% under HDHE and in 5.7% of the patients of the ASA-DHE-group. Superficial wound infections occurred under HDHE in 8.1%, under ASA-DHE in 5.7% of the patients, deep infections under HDHE in 0.5% and under ASA-DHE in 1.6% of the patients. Gastrointestinal bleeding under HDHE in 0.5% of the cases and under ASA-DHE in 3.1% of the cases. Prophylaxis had to be discharged in 7.6% of the patients of the HDHE-group and of 19.7% of the ASA-DHE-group. Pathologic perfusion scars should be found in 54.0% of the patients of the HDHE-group and in 54.9% of the ASA-DHE-group. Pulmonal perfusion became worse despite of prophylaxis by HDHE in 15.6% of the cases and despite prophylaxis with ASA-DHE in 17.6%. Pulmonal perfusion became better under HDHE in 11.9% and under ASA-DHE in 12.4% of the cases. The mortality was 9.7%. Fatal thromboembolism occurred under HDHE in three patients (1.4%) and under ASA-DHE in three patients too (1.6%), after subcapital fractures in 0.5%, after pertrochanteric fractures in 2.1% and after subtrochanteric fractures in 6.25% of the patients without any significant difference between the two groups of prophylaxis. Fatal gastrointestinal bleeding had to be remarked in 1.0% of the patients of the HDHE-group and in 2.1% of the ASA-DHE-group, fatal infections in 0.5% of the patients of the HDHE-group and in 1.6% of the ASA-DHE-group. Fatal cardinal infarction could be seen under HDHE in 1.9% of the patients, under ASA-DHE no fatal cardial infarction occurred.(ABSTRACT TRUNCATED AT 400 WORDS)
