A varicocele is a congenital varicosity of the pampiniform plexus due to an absence of valves in the left internal spermatic vein. Approximately 10% to 15% of men have a left varicocele, which may cause pain, testicular atrophy, and be a cause of male infertility later in life. The condition is detected in as many as 40% of men undergoing an infertility workup and in remaining 50%, of Male Infertility the cause is not found. Spermiography may reveal decreased motility and, in some men, a slight decrease in sperm count.
Traditionally, the diagnosis was made through clinical examination; however, as with other venous reflux disorders, ultrasound has become the mainstay of diagnosis. For diagnosis, we look for abnormal reflux on color Doppler with the Valsalva maneuver, rather than the diameter and number of dilated veins with the patient in the standing position.
The Indications for treatment include infertility in patients with appropriate semen abnormalities, chronic groin pain, testicular atrophy in adolescent varicoceles, and recurrent varicocele after previous repair. Other indications more recently described with variable strength of evidence include low serum testosterone (with or without erectile dysfunction), and enhancement of assisted fertility techniques.
The presence of a varicocele alone is not an indication for treatment, infertility treatment should only be performed for men with appropriate semen abnormalities. The proof that varicocele repair improves fertility remains elusive; however, there is general acceptance that treatment does improve abnormalities of semen production. However, sperm counts greatly vary from day to day in any individual patient, and these measures correlate poorly with infertility outcomes. It has long been known that spermatozoa of infertile men possess substantially more chromatin defects and DNA damage than sperm of fertile men.
First, scrotal ultrasound is performed on all patients.
Next, semen analysis is performed.
Alternative therapies are discussed, including no therapy or surgical therapy.
Informed consent is then obtained with the female partner in attendance.
The catheter is manipulated into the left spermatic vein after Vascular Access . A varicocele is present if the contrast refluxes into the pampiniform plexus. If varicocele is confirmed, the spermatic vein is occluded, by injecting liquid embolics with or without metallic coils.
The patient is kept in bed for 1 hour postprocedure. The patient is advised to take anti-inflammatory agents as needed and to avoid any activity involving the Valsalva maneuver, such as lifting, vigorous, or “hitting type” sports for 3 full days beginning the day after the procedure. Most patients report a minor dull ache in the back or groin lasting < 2 to 5 days. Fewer than 5% of patients will develop more severe pain lasting up to 14 days, requiring oral analgesics and anti-inflammatory agents and avoidance of vigorous exercise.
Varicocele embolization is safe and technically effective and achieves comparable results to surgery while offering the advantages of shorter recovery time, avoidance of general anesthetic, and patient preference.
