We investigated twelve patients who were died of PTE being hospitalized for non-cardiovascular disease. Their primary diseases were: orthopedics in 5 cases, neurosurgery in 3 cases, psychiatry in 3 cases, and obstetrics in 1 case. Two cases showed preexisting symptoms before death.
Their embolic source were detected at leg deep veins except one case at internal iliac vein. Ten cases had bilateral DVT and two had unilateral venous thrombi.
Histopathological feature showed that 8 cases were suggested suffered by single attack that contained only fresh thrombi. Rests were contained both fresh and organized thrombi that suggested recurrent DVT.
Soleal vein was the most frequent site of deep vein thrombosis that involved 83% of the limbs.
These results suggest that DVT of most in hospital patients were made after admission. And that most effectible factor of thrombosis is blood stagnation that tend to occlude bilateral crural leg veins.
As the most frequent site of thrombosis, soleal vein is important for primary prophylaxis of DVT. However, life-threatening emboli were thought to made as free-float thrombi made at ilio-femoral vein secondly to primary thrombosis at crural veins.
