POST OPERATIVE PULMONARY THROMBOEMBOLISM IS SEEN IN ALL EXCEPT

• A. Tall and thin man ✓
• B. Obese male
• C. Pregnant female
• D. Oestrogen therapy

Postoperative pulmonary thromboembolism is a serious complication that can occur after surgery. It refers to the formation of blood clots in the deep veins of the legs or pelvis, which can break loose and travel to the lungs, causing a blockage in the pulmonary arteries. Several risk factors have been identified for postoperative pulmonary thromboembolism, including immobility, surgery involving the lower extremities, and certain patient characteristics.

Among the options provided, postoperative pulmonary thromboembolism is least likely to be seen in a tall and thin man. This is because being tall and thin is generally not considered a significant risk factor for developing blood clots compared to other factors such as obesity, pregnancy, and estrogen therapy.

Obese males are at an increased risk of developing postoperative pulmonary thromboembolism due to their higher likelihood of having underlying conditions such as hypertension, diabetes, and cardiovascular disease, which can contribute to the formation of blood clots. Pregnant females are also at an elevated risk due to hormonal changes during pregnancy that can promote blood clot formation. Additionally, estrogen therapy can increase the risk of blood clots by altering the body’s clotting mechanisms.

In summary, while all individuals may be at some risk for postoperative pulmonary thromboembolism following surgery, tall and thin men are less likely to develop this complication compared to obese males, pregnant females, and individuals on estrogen therapy.
