Endovascular embolization of varicoceles using n-butyl cyanoacrylate (NBCA) glue

Varicoceles are abnormally dilated veins within the pampiniform plexus. They are caused by reflux of blood in the internal spermatic vein. The incidence of varicoceles is approximately 10-15% of the adolescent male population. The etiology of varicoceles is probably multifactorial. The diagnosis is based on Doppler US. Treatment could be endovascular or surgical. The aim of the study was to describe and evaluate a novel method of endovascular embolization of varicoceles using n-butyl cyanoacrylate (NBCA) glue. 17 patients were subjected to endovascular treatment of varicoceles using NBCA. A 2.8 Fr microcatheter and a 1:1 mixture of NBCA and lipiodol were used for embolization of the spermatic vein. All 17 procedures were successful. There were no complications. Embolization of varicoceles using NBCA glue is efficient and safe for all patients. The method should be considered as a method of choice in all patients. Phlebography and Valsalva maneuver are crucial for technical success and avoidance of complications. Endovascular treatment of varicoceles using NBCA glue is very effective and safe.
