the most serious complication of lower extremity phlebothrombosis is:
renal infarction
intestinal infarction
pulmonary embolism
myocardial ischemia

Explanation:

Lower extremity phlebothrombosis (venous blood clot in the lower limbs) can lead to a clot dislodging. This dislodged clot (embolus) can travel through the bloodstream. The pulmonary artery is a major pathway. If the clot reaches the lungs (pulmonary embolism), it can block blood flow to the lungs. This is life - threatening as it impairs gas exchange (oxygen intake and carbon dioxide release). Renal infarction (kidney tissue death), intestinal infarction (intestinal tissue death), and myocardial ischemia (reduced blood flow to the heart muscle) are less likely direct and most serious complications compared to the immediate and often fatal nature of a large pulmonary embolism from a lower extremity clot.

Answer:

Pulmonary embolism
