Digital subtraction angiography and pulmonary vascular anomaly. Two case reports.
Two cases are described in which a tortuous pulmonary density, suspicious of vascular anomaly, was studied using venous digital subtraction angiography. One proved to be a pulmonary varix, the other an A-V fistula. The establishment of the diagnosis of such lesions is discussed and the value of D.S.A. is emphasized in comparison with conventional pulmonary angiography by right heart catheterization.
