[Clinical analysis of 45 cases with pulmonary thromboembolism after surgical procedures]

To analyze the occurrence of pulmonary thromboembolism (PTE) after surgical procedures to attract more attention to the prevention, diagnosis and treatment of this disease.

Retrospectively analyze the clinical data of the hospitalized patients with post-surgical PTE from June 2004 to February 2009. The average age of the 45 cases was (60 +/- 16) years old, 35 cases received anticoagulant therapy and 6 cases received thrombolytic therapy, the other 4 cases only received emergency medical treatment. Analyze the data about the surgery category, duration, anaesthetic way, risk factors, clinical symptoms, auxiliary examinations, diagnosis, treatment and turnover of these patients.

Among the total 45 cases of post-surgical PTE, 37 cases (82.2%) occurred within 2 weeks, it accounted for 13.2% (45/341) of the hospitalized PTE patients during that period. PTE was often seen in patients after major surgical operation such as general (35.6%), gynecological (13.3%), orthopedic (13.3%) and chest surgery, especially the surgery related to malignant tumor (57.8%). The average surgical duration was (220 +/- 124) min, 37 cases (82.2%) was given general anaesthesia. The clinical manifestations and auxiliary examinations results of post-surgical PTE were not typical. Thirty-six cases improved after treatment, 9 cases died and the case fatality ratio was 20.0% (9/45).

Surgical procedure is an important risk factor of PTE. The prevention diagnosis and treatment of post-surgical PTE should be paid more attention to.
