Capillary congestion is defined as the blocking of the capillaries, that is, the blood vessels that carry blood which is rich in oxygen and essential nutrients to the tissues of the human body at a cellular level. The congestion of the capillaries makes people prone to a rare but acute renal dysfunction. This renal dysfunction is histological and clinically unusual, but more prevalent in those people who have been the recipients of a kidney transplant operation.
Histological lesions are basically the result of this congestion of the capillaries. It is usually associated with such conditions as capillary thrombosis, arteriolar thrombosis and parenchymal necrosis. Acute cellular rejection is typically characterised by such features as tubulitis, glomerulitis, edema and infiltrate. Capillary congestion is in contrast with the absence of these conditions.
The corresponding clinical history of patients is characterised by the early timing of the occurrence of the histological lesion in the course of the transplantation, which is usually less than three months. The lesion occurs all of a sudden, even in the cases of those patients who usually have a good transplant function. This leads to the most advanced stage of renal failure in a few days. Subsequently, under rejection treatment, the resolution also fails.
