Among our 33 patients, 15 (45%, 14 M/1 F) patients relapsed with LEDVT, 7 patients had isolated STM and 11 patients had no further vascular events during the 40.7 ± 13.4 months of follow-up. If DVT is not treated there is a risk of Pulmonary Embolism (PE). Prophylaxis and risk assessment are important aspects of DVT management. The clinical importance of DVT is influenced by unique factors such as cardiopulmonary reserve among mechanically ventilated patients. Clinical and applied thrombosis/hemostasis.

Deep vein thrombosis (DVT) is the formation of a thrombus (blood clot) in a deep vein, usually in the legs, which partially or completely obstructs blood flow. The prevalence appears to be increasing, particularly because of an increased use of indwelling central venous catheters.
