Chronic limb-threatening ischemia is a significant source of morbidity, amputation, and mortality. Although many patients are candidates for endovascular or surgical bypass therapies, an increasing number of patients are not amenable to these procedures. Percutaneous lumbar sympathectomy is a minimally invasive procedure that has been associated with improvements in patients’ pain and ulcer healing. This report describes a case of computed tomography-guided lumbar sympathectomy for palliative treatment of severe rest pain in a patient who was not a candidate for either open or endovascular treatments, which resulted in successful palliation of the patient’s symptoms.

Phantom limb pain (PLP) is a common complication after major lower extremity amputations (MLEA), occurring in approximately 85% of patients. PLP significantly affects amputees’ mobility, ability to perform tasks of daily living, and overall quality of life (QoL). Previous studies have discussed surgical treatments for PLP that can improve ambulation and mobility after MLEA. The authors describe 3 patients who underwent peripheral nerve repair PNR to alleviate PLP and reported decreased pain and improved QoL.

Despite a recent increase in research efforts regarding disparities in peripheral arterial disease/critical limb-threatening ischemia (PAD/CLTI), few studies have focused on minority and women participation in late-breaking clinical investigations exploring various treatments for PAD/CLTI. The authors seek to explore the representation of minority groups and women in clinical studies evaluating the usage of drug-coated balloons for treatment in PAD/CLTI.

Presence of calcification is a significant risk factor for treatment resistance during endovascular therapy, limiting vessel expansion and increasing rates of complication. The goal of this study is to assess the safety and efficacy of intravascular lithotripsy in the treatment of calcified peripheral arterial lesions in patients with claudication. 

The pattern of surgical bypass has affected practice in the context of a multidisciplinary limb preservation program. As bypass may be required for limb preservation, such a practice would involve more frequent bypass and increased complexity of bypass performed due to the lack of an autogenous conduit and suitable target artery (“desert foot”), and patients with prior failed endovascular interventions. We investigated this change in the pattern of bypass performed in the context of our limb preservation program.
