Endovascular treatment in varicocoele

Clinical History

A 33-year-old male patient presented to the OPD with complaints of heaviness and boggy swelling in the scrotum which was more during his work and while walking, these complaints have aggravated more since the last 3 months.

Imaging Findings

On clinical examination a swelling was noted on the left side in an erect posture at rest and a swelling was seen bilaterally on performing Valsalva's manoeuvre. A Doppler was performed which revealed prominent dilated veins on the left side with reflux and mildly prominent veins without reflux on the right. Patients semen analysis showed deranged values suggestive of varicocoele leading to infertility. Patient was referred to the Intervention Radiology team for endovascular management as patient did not want a surgical treatment. Endovascular embolisation was planned, a right femoral vein access was achieved and a 5F sheath placed. The left renal vein was cannulated with a 5F Cobra catheter, the left internal spermatic vein was visualised and selectively cannulated, Valsalva's manoeuvre was performed to demonstrate reflux and two 3mm Nester coils were used for embolising the vein.

Discussion

Varicocoele is a condition characterised by abnormal dilated pampiniform plexus veins in spermatic cord. The condition affects up to 15% of the male population. Primary infertility is seen in 35% and secondary infertility is seen in up to 80% of cases [1]. Varicocoele cases are of two types: a) primary and b) secondary. Varicocoele leads to progressive impaired semen parameters. These patients are usually asymptomatic however sometimes with complaints of scrotal discomfort. Diagnosis of the condition is made by clinically by eliciting a detail reproductive and sexual history along with physical examination performed in standing position both at rest and while performing Valsalva's manoeuvre. Scrotal ultrasound is very sensitive and specific (97% and 94% respectively) [2]. Criteria to diagnose varicocoele includes dilated spermatic vein with demonstration of reversal of flow on colour doppler. Dilated vein diameter more than 2-3 mm is taken as cut off. Varicocoele correction is performed in patients with deranged semen parameters and failure of conservative treatment in scrotal pain.
Percutaneous treatment is least invasive and is performed under local anaesthesia. Venography helps in planning the procedure by visualisation of internal spermatic vein. The first percutaneous intervention was attempted by Lima et al. using glucose and sclerosant as the embolic material [3]. The procedure can be performed by both transfemoral and transjugular routes. Transjugular route is mostly used to treat the right sided varicocoele. Both solid and liquid embolic agents can be used and is mainly dependant on the operator choice. The disadvantage of solid ecbolics include venous perforation or coil migration and that of liquids include non target embolisation, Cather entrapment and infection [4]. Post procedure the patient is advised to avoid strenuous activity for couple of days and is followed up with doppler at 3 months and semen evaluation at 6 months. Cayan et al. reported a technical failure rate of 13.05% for percutaneous treatment [5].
