Key result
More extensive thoracic surgery is linked to a 4-fold higher risk of deep-vein thrombosis.
Why the study?
The incidence of deep-vein thrombosis after major non-cardiovascular thoracic surgery was not well characterized, indicating a need for thromboprophylactic measures.
Observational (n=44)
The incidence of DVT after major non-cardiovascular thoracic surgery is substantial (18%), indicating a need for routine thromboprophylactic measures in this population.

May support intensified DVT prophylaxis review after extensive thoracic surgery; hypothesis-generating and requires prospective validation.
The incidence of deep-vein thrombosis (DVT) verified by fibrinogen test was studied in 44 high-risk patients after major non-cardiovascular thoracic surgery. In eight patients (18%) a total of ten DVT appeared within the first postoperative week. Four thrombi were located at or above knee level. More extensive surgery was associated with higher DVT incidence than lesser operations (32% v. 8%). In patients belonging to blood groups B and AB, DVT was more common than in other blood groups. Five of the six unilateral DVT were detected on the same side as the thoracotomy. The findings suggest that DVT incidence after this kind of surgery may be of the same order as after major general surgery, indicating a need for thromboprophylactic measures.

Karl-Gösta Ljungström (1985) conducted an observational in Major non-cardiovascular thoracic surgery (n=44). More extensive surgery vs. Lesser operations was evaluated on Deep-vein thrombosis (DVT) verified by fibrinogen test. More extensive non-cardiovascular thoracic surgery was associated with a higher incidence of deep-vein thrombosis compared to lesser operations (32% vs 8%).
