Thromboembolic Disorders in Pregnancy
Diagnosis
Doppler ultrasonography or sometimes CT with contrast for DVT Helical CT for PE Diagnosis of DVTis usually by Doppler ultrasonography. In the postpartum period, if Doppler ultrasonography and plethysmography are normal but iliac, ovarian, or other pelvic venous thrombosis is suspected, CT with contrast is used. Diagnosis of PEis increasingly being made by helical CT rather than ventilation-perfusion scanning because CT involves less radiation and is equally sensitive. If the diagnosis of PE is uncertain, pulmonary angiography is required.
