Summary
Laparoscopic extravascular stent placement effectively managed nutcracker syndrome in three patients, relieving severe hematuria and varices. This minimally invasive approach shows promise for treating this venous compression disorder.
Area of Science:
- Urology
- Vascular Surgery
- Minimally Invasive Surgery
Background:
- Nutcracker syndrome, characterized by left renal vein compression, can cause severe hematuria and gonadal vein varices.
- Diagnosis is confirmed via imaging and endoscopic evaluation, revealing venous entrapment between the aorta and superior mesenteric artery.
Purpose of the Study:
- To evaluate the efficacy and safety of laparoscopic extravascular stent placement for managing nutcracker syndrome.
- To report on the surgical experience with this novel minimally invasive technique.
Main Methods:
- Three patients with symptomatic nutcracker syndrome underwent laparoscopic extravascular stent placement in the left renal vein.
- Procedures were monitored for complications, and patients were followed for 16–37 months post-surgery.
Main Results:
- The laparoscopic procedure was performed without complications in all patients.
- Two male patients achieved complete symptom relief, with no recurrence of hematuria or varices.
- One female patient experienced partial relief from microhematuria.
Conclusions:
- Laparoscopic extravascular stent placement is a feasible and effective treatment for nutcracker syndrome, particularly in severe cases.
- This minimally invasive approach can successfully reestablish renal venous outflow and alleviate symptoms.
- Further long-term studies are needed to solidify its role in clinical practice.

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...
