Nutcracker surgery is major surgery. Nutcracker is mainly the left renal vein compression syndrome, which is mainly when the left renal vein enters the vena cava and it crosses the angle between the superior mesenteric artery and the abdominal aorta, and this small angle causes the left renal vein to be compressed. There are several surgical options, one being a minimally invasive procedure in which a stent is placed in the left renal vein to dilate the left renal vein and relieve the compression. Another way is to relocate the left renal vein where it meets the inferior vena cava to reduce the pressure on the left renal vein.
