Some patients with chronic pulmonary embolism causing severely symptomatic pulmonary hypertension have been managed by heart-lung transplantation with an associated hospital mortality of 24%. To allow comparison with pulmonary thromboendarterectomy (PTE), we have reviewed the hospital morbidity and mortality in 149 consecutive patients. From 1 October 1984 to 18 September 1989, these patients underwent PTE utilizing a standardized procedure consisting of median sternotomy, cardiopulmonary bypass, deep hypothermia and circulatory arrest for bilateral PTE in 91% (136/149) of the procedures with 7.4% (11/149) and 1.3% (2/149) undergoing right or left PTE, respectively. Ventilator dependency (greater than or equal to 5 days on respirator) occurred in 28.3% (41/146). Hospital mortality (death within 30 days or in hospital) was 11.4% (17/149). The most common causes of death were respiratory and multiorgan failure, 10 (59% of deaths) and acute pulmonary hemorrhage, 3 (17% of deaths). We conclude that PTE with an operative mortality of half that of heart-lung transplantation (11.4% vs. 24%) should be the procedure of choice for significantly symptomatic chronic pulmonary embolism. Furthermore, the hazards of immunosuppression and chronic graft rejection are avoided.

UI	MeSH Term	Description	Entries
D006976	Hypertension, Pulmonary	Increased VASCULAR RESISTANCE in the PULMONARY CIRCULATION, usually secondary to HEART DISEASES or LUNG DISEASES.	Pulmonary Hypertension
D007036	Hypothermia, Induced	Abnormally low BODY TEMPERATURE that is intentionally induced in warm-blooded animals by artificial means. In humans, mild or moderate hypothermia has been used to reduce tissue damages, particularly after cardiac or spinal cord injuries and during subsequent surgeries.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).
