Positive and negative effects of anticoagulant treatment during and after arterial embolectomy.
Eighty-four consecutive patients subjected to arterial embolectomy were studied. Cardiac arrythmia was found in 64% of the cases. The incidence of upper limb embolus was 15%, and lower limb 85%. Our total results are in agreement with most reports--the limb salvage rate of survivors was 84%, and the amputation rate was 16%. The primary mortality, 18%, is a rather low figure considering the high mean age (72 years) of the material. The prognosis after embolectomy was dependent on time from onset of symptoms and on the age of the patient. In the group of patients treated with anticoagulants the primary mortality was 7%, and in the untreated group 26%. The results of this investigation of patients treated with arterial embolectomy indicate: Adequate anticoagulant treatment during the per- and postoperative period decreased the primary mortality significantly, possibly as a result of fewer thromboembolic complications. The anticoagulant treatment was associated with a higher frequency of local complications as postoperative hemorrhage and reocclusions, which increased the frequency of reoperations and amputations. These drawbacks of anticoagulant treatment could possibly be counteracted by proper measures during the operation.
