PURPOSE
The Nutcracker Syndrome (NCS) refers to symptomatic compression of the left renal vein (LRV). This can occur when
the LRV traverses in the normal anatomic position- in the angle between the aorta and the superior mesenteric artery,
or when the LRV is retroaortic - in an anomalous location as can be found in 1.8% of autopsies.
When symptoms such as hematuria, abdominal/pelvic pain or varicocele are sufficiently severe to warrant surgery,
various types of surgical shunts have been utilized. Li et al (1) reported a microsurgical spermatic – inferior epigastric
vein anastomosis in infertile men and Dong et al (2) performed this for adolescents with varicocele and NCS. Both of
these authors utilized more difficult, hand sewn anastomoses. The venous coupler device is used extensively for
microvascular surgery, but has not been reported for correction of NCS.
MATERIAL AND METHODS
A 13 year old boy with a symptomatic varicocele and solitary left testicle had chronic scrotal/abdominal pain. Doppler
LRV sonography and CT scan confirmed a retroaortic LRV as the cause of his NCS, with gonadal and renal venous
dilatation
RESULTS
Through a left inguinal incision, the internal spermatic vein was divided. The distal stump was ligated and the proximal
end of the internal spermatic vein was anastomosed to the inferior epigastric vein in a simplified fashion using the
venous coupler device and this is depicted. On postoperative imaging, the size of the pampiniform plexus and the LRV
normalized and the symptoms completely resolved.
CONCLUSIONS
Adolescents with symptomatic primary or recurrent varicocele should be evaluated for the presence of NCS. When NCS
is present, a venous shunt should be performed and the venous coupler greatly facilitates this procedure.
