Nephrotic syndrome is a high-risk factor for cerebral infarction, making patients prone to strokes. This is because patients with nephrotic syndrome excrete large amounts of protein in their urine, which reduces protein concentration in the plasma and disrupts the anticoagulant fibrinolysis system, leading to an increased tendency to form blood clots. These clots are prone to develop in the veins of the lower extremities and the renal veins, and cerebral arteries in the skull are also susceptible to occlusion. Therefore, in such patients, if the plasma albumin level is very low, such as below 20 grams per liter, there is a need for routine use of anticoagulant medications.
