Use of intraoperative microvascular Doppler during subinguinal microsurgical varicocelectomy in children reduces complications.

Background/Aim: This study assessed the impact of intraoperative microvascular Doppler ultrasonography (MDU) during microsurgical subinguinal varicocele correction in children. Materials and methods: Nineteen patients who underwent intraoperative MDU during subinguinal microsurgical varicocelectomy between 2021 and 2023 were included in this study. Each patient's age, varicocele side, clinical examination findings, preoperative ultrasonography results, intraoperative findings, spermatic artery counts and findings in terms of MDU use, postoperative complications, and results were evaluated. Results: All varicoceles were on the left side and the average age of the patients was 15.2 years. The indications for varicocelectomy were testicular hypotrophy (n = 10) and scrotal pain or fullness (n = 9). When a surgical microscope was used, testicular artery pulsation was detected in only five patients, whereas it was detected in all cases when MDU was used. In 16 cases, a single testicular artery was identified, and two arteries were identified in three cases. Additionally, in a case where a spermatic vein was suspected, it was not ligated due to the detection of pulsation with an arterial pattern using MDU. Two to three lymphatic channels were isolated and preserved, an average of 7.5 vessels were ligated, and five external spermatic veins were identified and ligated. There were no complications, and six of the patients with testicular hypotrophy showed signs of the catch-up growth phenomenon. Conclusion: The use of MDU during subinguinal microsurgical varicocelectomy in children not only increases the success rate but also minimizes complications such as hydrocele and recurrence.
