[Evaluation of the relationship between deep venous thrombosis and pulmonary embolism with radionuclide techniques].
OBJECTIVE
The purpose of this study was to evaluate the relation between deep venous thrombosis (DVT) and pulmonary thromboembolism (PTE) by radionuclide imaging.


METHODS
One hundred forty patients with PTE from September 1997 to March 2001 at this institution was confirmed by clinical manifestation, pulmonary perfusion (PPI)/ventilation scan (PPV) and deep venous radionuclide venography (RNV), which were performed in all patients. There were 79 males and 61 females, with an average age of 39 +/- 18 years. Twenty-six cases underwent pulmonary angiography; 11 underwent X Ray venography of lower extremities (XRV); 18 underwent impedence plethymography (IPG); and 36 underwent lower limb echocardiography (UCG).


RESULTS
Of the 140 patients with PTE, 120 (85.7%) had lower limb venous pathological changes. Among them, 94 patients had risk factors for DVT. The agreement rates of RNV with XRV, UCG and IPG were 90.9%, 72.2% and 80.0%, respectively.


CONCLUSIONS
The results indicated that DVT was highly prevalent in patients with acute pulmonary embolism. Thrombosis was a primary pathogenic factor for PTE, and thrombi were mostly from proximal veins. (99m)TC-MAA radionuclide imaging was a useful method for noninvasive detection of DVT and PTE.
