is renal vein thrombosis a type of venous thromboembolism?

Answer 1

Renal vein thrombosis (RVT) is the formation of a clot or thrombus obstructing the renal vein, leading to a reduction in drainage of the kidney.

This thrombosis can lead to imbalances in blood clotting factor. Its symptoms may include blood in urine or being diminished in volume. Surgery to remove the clot is possible, but rarely performed.

A venous thrombosis is a blood clot that forms within a vein.

Since the veins return blood to the heart, if a piece of a blood clot formed in a vein breaks off it can be transported to the right side of the heart, and from there into the lungs. A piece of thrombus that is transported in this way is an embolism: the process of forming a thrombus that becomes embolic is called a thromboembolism. An embolism that lodges in the lungs is a pulmonary embolism (PE).

Systemic embolisms of venous origin can occur in patients with an atrial or ventricular septal defect, through which an embolus may pass into the arterial system. This is termed a paradoxical emboli.
