cardiac hydatid cyst (chc) is a rare disease that was endemic in some regions especially in sheep-raising areas. the most commonly accepted theory for the routes of heart involvement in hydatid cyst was infestation by the hexacanthus embryo through coronary arteries. here, we describe a case with the primitive cardiac hydatid cyst located around the pulmonary valve (pv) and main pulmonary arter...

CONGENITAL ABSENCE of a main pulmonary artery branch is now a wellrecognized clinical entity, more than 60 cases having been reported in the literature. Diagnosis has heretofore been based primarily oln radiologic findings' in both routine x-rays and angiocardiography. Physiologic studies of pulmonary function, including differential bronchospirometry, however, provide valuable diagnostic infor...

Pulmonary artery aneurysm is a rare lesion of the thoracic cavity. Different etiologies have been reviewed, but idiopathic lesions without other symptoms are seldom reported. Usually, surgical interventions are suggested, but the long-term outcomes are not well established. Here, we report a 24-year-old man with main pulmonary artery aneurysm who successfully underwent aneurysmectomy and polyte...

conclusions our case highlights the fact that the tip of the pulmonary artery catheter can easily advance into a peripheral branch of the pulmonary artery and cause pulmonary venous blood to be sampled instead of pulmonary arterial blood. a variety of monitoring techniques are needed to confirm accurate catheter placement. background pressure and waveform at the catheter tip are continuously mo...

pulmonary arteriovenous malformations are rare clinical entities thai are associated with right to left shunts, and are often clinically presented by the triad of dyspnea, cyanosis, and digital clubbing. currently, transcatheter embolization of fistula is gaining increasing popularity as the superior therapeutic option. in certain situations, however, surgery is preferred. two cases of direct p...

hydatid cyst (hc) is a parasitic disease that may involve many organs, especially the lung and the liver. pulmonary artery location of the hydatid cyst is extremely rare, but it may cause life-threatening complications. we report a case of a hydatid cyst that completely filled the left main pulmonary artery and its distal part without cardiac involvement. thoracic computed tomography showed fil...
