Abstract

We assessed the clinical status after anticoagulant therapy in acute deep vein thrombosis (DVT) involving the lower limbs. Between 1994 and 2001, 139 patients suffering from acute DVT were treated with heparin therapy followed by oral anticoagulant therapy. The coagulation factor assay was done prior to any anticoagulation therapy. The duplex scan was checked serially. The mean follow-up periods was 32 ± 19 months. There were 32 (23.0%) cases of protein C deficiency, 12 (8.6%) cases of protein S deficiency, 13 (9.4%) cases of AT-III deficiency and 11 (7.9%) cases of abnormal plasminogen level. Fourteen cases had coagulation factor abnormalities within the family. The initial lung scan showed 29 (20.9%) cases with high, 13 (9.4%) cases with intermediate and 70 (50.4%) cases with a low probability of pulmonary embolism (PE) developing. During the follow-up periods, there were 3 cases of non-fatal PE documented with chest CT scan. The patients were divided according to the extent of the thrombus; Group I (38 cases) was limited to the infrainguinal deep vein, Group II (70 cases) extended to the iliac vein and Group III (9 cases) extended to the vena cava. Partial lysis occurred in 20/35/3 (52.6/50.0/33.3%) cases and no change in 10/24/6 (26.3/ 34.3/ 66.7%) cases in Groups I/ II/ III, respectively. Deep vein valvular reflux occurred in 15/25/5 (39.5/35.7/55.6%) cases in Groups I/ II/ III, respectively. With anticoagulation therapy, most of the thrombi remained in unresolved states and there was a high rate of deep vein valvular reflux. However, there was no serious complications which affected the patients' quality of life.
