Objective: To evaluate the efficacy and safety of the valvulotome device used to cut venous valves and in situ bypass in the treatment of peripheral arterial disease (PAD) of the lower extremities.
Methods: In this study, the basic principles of in situ saphenous vein bypass are mentioned, specifically for a novel valvulotome device (NODR Valvulotome device, Invamed/ Ankara/Turkey). In this context, the effectiveness of the method was evaluated by interpreting the results of some studies on in situ saphenous vein bypass.
Results: In situ bypass has an effective rate for long-term outcomes with approximately 80%, 90% and 95% for primary patency (no evidence of restenosis with a maximum systolic rate >2.5 or sonography-based occlusion), secondary patency (patency maintained by repeated intervention after complete bypass occlusion), and limb salvage (absence of major amputations), respectively. The side effects, including vessel perforation and intramural bleeding, are very low. The technical success rate is very high. Valvulotomes are easy to use by the surgeons and provide comfort for the patients.
Conclusions: In situ bypass is effective and safe in PAD treatment. Valvulotome provides ease of use for surgeons and comfort for patients.
