To the Editor
The excellent series of successful pulmonary endarterectomies reported by Dr Thistlethwaite and colleagues from the University of California at San Diego is truly inspiring [1]. Of special note is their success rate for concomitant coronary and valvular abnormalities.
Doctor Chitwoods discussion of this report [1] may be in error stating "Dr Sabiston and our colleagues at Duke performed the first pulmonary embolectomy for chronic emboli in 1970. There, the surgical pathophysiology of this complex disease was first studied and defined."
In 1963, in the American Journal of Medicine [2], we reported a successful pulmonary thromboendarterectomy for chronic thrombotic obstruction performed in 1961 at the Naval Medical Center, Bethesda, MD. The pathophysiology and diagnostic studies were carefully defined, including ventilation-perfusion ratios, right heart and pulmonary artery pressures, A-a gradients, blood gas analyses, and cineangiographic data, a review of the literature was included. Six-week and 6-month follow-up studies were included in this report. Parenthetically, I received personal communication from the patient (K.E.) in 1988, a 27-year follow-up reporting continued good health.
Although Jamieson and associates [3] credited Allison and associates [4] with the first successful operation for "chronic embolization," only 27 days elapsed from initial symptoms to surgical intervention in their case. Symptoms in the case we reported progressed over a 10-month period.
