Three cases of pulmonary hypertension caused by hydatid emboli from the right side of the heart are described; cardiac catheterisation was performed in 2. One case was confirmed at operation and 2 at necropsy. The pulmonary emboli were caused by hydatid vesicles in all 3 cases and in none was there pulmonary thrombosis; free scolices were found in the pulmonary alveoli in 2. In 1 patient with r...

I report the case of a woman with systemic lupus erythematosus who had pulmonary hypertension unassociated with chronic interstitial lung disease or pulmonary emboli. She had started taking the contraceptive pill seven months previously.

After inhalation, C15O2 (T1/2 = 2 minutes) rapidly diffuses into pulmonary blood and is cleared from the lungs within 10 seconds. The purpose of this study was to determine whether impaired clearance of inhaled C15O2 from oligemic zones, distal to areas of obstructed pulmonary blood flow, could be detected by serial pulmonary imaging with a positron camera. Experimental obstruction of branches ...

TODAY THROMBOSIS and embolism are the commonest causes of death after a major abdominal operation (Muir, 1968). Since 1960 thrombosis and embolism have been the leading cause of maternal death in England and Wales (Jeffcoate and Tindall, 1965). Morrell, Truelove and Barr (1963) confirmed a marked increase in the decade 1952 to 1961. These findings contrast with the reported incidence in African...

Tumour emboli from an endocardial metastasis of an endometrial stromal sarcoma caused recurrent and ultimately fatal strokes in a woman of 40. Endocardial metastases are rare. They are known to embolise to the pulmonary and systemic arteries but not to cause recurrent cerebral emboli.
