| Popis: | Objective To evaluate the feasibility and safety of a new laparoscopic technique for resection of a fibrous ring and extravascular stent implantation in patients with nutcracker syndrome (NCS). Material and Methods We retrospectively reviewed data of 5 patients diagnosed with NCS between March 2010 and February 2016. The mean age of the patients (4 male and 1 female) was 34 years (range, 28-40 years). All 5 patients underwent laparoscopic resection of the narrow fibrous ring around the left renal venous (LRV) and for extravascular stent implantation in the LRV for management of NCS. Results The average operating time was104 minutes and the average blood loss during surgery was 59 mL. The average length of the postoperative hospital stay was 6 days (range, 4-8 days). In all 5 patients, the symptoms of macroscopic hematuria started decreasing gradually and resolved after surgery. Postoperative computed tomography showed that the blood outflow from the LRV was smooth. The ratio of the dilated segment's inner diameter to the diameter of the strictured segment decreased from 3.4 to 9.5, preoperatively to 1.1-2.0, postoperatively. The mean follow-up period was 17.6 months (range, 8-24 months).One patient's varicocele was cured and symptoms in all 5 patients resolved after surgery. None of the patients showed symptom recurrence. Conclusion Laparoscopic surgery, for the placement of an extravascular stent and resection of the fibrous ring around the end of the LRV outflow to the inferior vena cava appears feasible and safe and offers an alternative minimally invasive for the management of NCS. |
