Abstract
Manifest cardio-pulmonary bilharziasis as seen in Egypt almost always develops in conjunction with hepato-splenomegaly; hence the name of porto-pulmonary bilharziasis is suggested. The disease was first described clinically by Azmy and Effat in 1932 [2] under the name of Bilharzial Ayerza. Repeated showers of bilharzia ova are deposited in the peripheral branches of the pulmonary artery and are responsible for the subsequent occlusive angeitis in and around the arterioles along with the formation of angiomatoids [12]. Early in our studies it was noticed that the size of a main pulmonary artery bore little or no relationship to the sustained pressure, that is, the pressure in an aneurysmal pulmonary artery which may even contain large fibrin clots may be distinctly lower than in a correspondingly smaller artery in another patient [14]. In the former group, the oxygen saturation in the pulmonary artery showed a significant increase as the catheter was advanced from proximal to distal [17], the sampling site being kept carefully away from the wedged position. Evidence for the left to right shunt was demonstrated by two procedures [15].
