| Background Lumbar sympathectomy (LS) was traditionally performed for intermittent claudication but is now eclipsed by revascularization for that indication. However, it retains a role in the management of chronic limb-threatening ischemia and other conditions causing lower limb pain with or without ischemia. In this study, we identify its role in the management of chronic limb-threatening ischemia in cases of nonreconstructable peripheral arterial disease. Aim The main aim of this study is to determine if LS procedure has an effective role in limb salvage and pain control for patients with nonreconstructable peripheral limb ischemia. The primary endpoint was limb salvage in the target limb, while the secondary endpoint targeted assessment of pain improvement in the same limb. Patients and methods This study is a prospective single-arm cohort study conducted using 21 patients between the January 1, 2021 and the January 1, 2023 at two hospitals, Ain Shams University Hospital and Nasser Institute Hospital. Patients complained of nonreconstructable peripheral arterial disease and there was no chance for revascularization either endovascular or surgical bypass. Results This study included 60 patients; one patient was excluded due to being lost to follow-up, and presented with nonconstructable critical limb ischemia between the January 1, 2021 and the January 1, 2023. There were 42 (70%) males and 18 (30%) females. Follow-up for all patients was subjected to measurement of ankle brachial pressure index, digital pulse oximetry, toe pressure and numerical rating scale for pain scoring preoperative and postoperative. On follow-up we noticed that there was no change in either ankle brachial pressure index or toe pressure immediately postoperatively and after 12 months. However, the digital pulse oximetry showed significant improvement immediately postoperatively from 68.40±7.36 to 81.15±12.23 with a value of 0.001. The most remarkable improvement was found in pain scoring immediately, 1, 3, 6, and 12 months postoperatively with values showing statistical significance. As for limb salvage, there was a 100% limb survival for 3 months. After 6 months, only nine cases underwent above-knee amputation, one of them was due to severe limb infection, and three cases had minor amputation ‘toe amputation.’ We noticed that three out of the nine cases suffering major amputations had femoropopliteal disease. Of the patients, 80% suffered no minor or major amputation, while 15% had major amputations beyond the tarsometatarsal joint and only 5% underwent minor toe amputation or debridement. Fortunately, there was no mortality among the studied cases. Conclusion Retroperitoneoscopic LS is significantly less invasive than open surgical technique with fewer wound complications and less hospital stay period and offers a longer duration of pain relief and less incidence of recurrence of manifestations. | ||||
