Analysis of 1084 consecutive lower extremities involved with acute venous thrombosis diagnosed by duplex scanning.
A retrospective analysis of 8658 consecutive lower extremity venous duplex scans performed between the years 1982 to 1988 revealed 953 patients with involvement of 1084 extremities with acute deep or superficial thrombi. Records of patients with acute thrombi were then evaluated for the incidence, location, and patterns of distribution. There were 485 women (50.9%) and 468 men (49.1%), with a mean age of 62.9 +/- 16.7 years and 58.8 +/- 15.2 years, respectively. There were 371 right-sided thrombi (180 women and 191 men), 451 left-sided thrombi (235 women and 216 men), and 131 (70 women and 61 men) patients with thrombi in both lower extremities. Women were found to be uniformly older, and the left leg was found to be involved more frequently (p less than 0.05). The overall distribution of the 3169 veins involved with acute thrombi in decreasing order were: popliteal, 16.1%; superficial femoral, 15.0%; posterior tibial, 13.4%; common femoral, 13.2%; greater saphenous, 9.9%; soleal, 9.1%; peroneal, 7.2%; deep femoral, 6.6%; lesser saphenous, 5.7%; anterior tibial, 2.0%; varicosities, 1.6%; and perforating, 0.3%. A different rank order was found in analysis of single thrombus patterns as follows: greater saphenous, 27.5%; soleal, 20.1%; lesser saphenous, 13.4%; varicosities, 8.8%; popliteal, 8.1%; posterior tibial, 9.1%; common femoral, 3.5%; superficial femoral, 4.9%; peroneal, 2.8%; deep femoral, 1.0%; anterior tibial, 0.3%; and perforating, 0.3%. In patients with multiple and bilateral thrombi there was a large number of unique patterns of thrombosis. Locations, patterns, and frequency of acute venous thrombi vary with age, sex, and leg involved. Patterns and statistical analyses of pertinent observations were performed.
