Left renal vein compression syndrome

Left renal vein compression syndrome is also known as nutcracker syndrome. Anatomically, there is an angle between the superior mesenteric artery and the aorta, and the left renal vein passes through this angle. If the angle between the superior mesenteric artery and the aorta is too small, it will cause compression of the left renal vein, thus increasing the blood pressure returning from the left renal vein, causing hematuria under the environment. In severe cases, it will cause macroscopic hematuria. This condition is currently more slender patients, tall, thin body will cause the angle between the superior mesenteric artery and the aorta is too small, if not very serious hematuria can be treated conservatively by weight gain method, if the nutcracker syndrome caused by hematuria is very serious, causing severe anemia, sometimes may need surgery to treat.
