[pulmonary thromboembolism in hospitalized patients during the period 1994-2000: an autopsy study]

Pulmonary thromboembolism (PTE) has been for a long time a significant cause of morbidity and mortality in hospitalized patients. The utility of Low-Molecular Weight Heparins (LMWH) in these patients in the last decade of the XX century has decreased the incidence of this disease. We try to know if the massive useful of LMWH as thromboprophylasis is diminishing its incidence in autopsies.

Retrospective study of all the autopsies in adults in the Hospital Clínico San Carlos (Madrid) in a period of 6 years (from January 1994 to December 1999). There were reviewed those necropsies which had pathological data of pulmonary thromboembolism and several items were studied: anatomopathological, epidemiological, clinical and therapeutical.

483 necropsies were performed in this period; 40 (8.3%) had PE. Most of them were older than 50 years (85%) and the most important risk factors associated were bedridden, chronic cardiovascular diseases and malignant neoplasias. Only Pre-mortem diagnosis was only suspected in 5 patients (12.5%) and 15 of them (37.5%) had a fatal pulmonary embolism despite receipt of thromboprophylasis with LMWH.

PTE is still an important cause of mortality in hospitalized patients. The increased of life expect, survival of chronic cardiovascular and malignant disease made PTE a frequent possibility situation in hospitalized patients. Receipt of LMWH as thromboprophylaxis is not always effective to avoid PTE.
