Purpose: Chronic limb-threatening ischemia (CLTI) represents the clinical end stage of lower extremity peripheral arterial disease (PAD). Although conventional open and endovascular revascularization options are available, some CLTI patients do not respond to these treatments, generally due to small vessel occlusive disease, with only limited or no clinical improvement achieved. This article aims to provide insights related to pertinent venous anatomy of the leg and below the ankle and a technical review of percutaneous deep venous arterialization (pDVA) creation using commonly-available devices. Technique: For patients with "no-option" CLTI, the risk of major amputation and mortality remains high. Although arterial revascularization remains the optimal treatment of CLTI, some patients with severely-diseased or gracile distal arteries have poor outcome. Deep venous arterialization (DVA), in a subset of patients with tibial anatomy amenable to DVA creation, represents the last-ditch attempt before these patients are deemed to have "no-hope" at limb salvage, and major amputation becomes necessary. Refinement in technique and advancement in device development have been shown to allow pDVA to be created with respectable outcomes for the "no-option" CLTI patient population. Conclusion: The pDVA has garnered increasing interest among endovascular specialists to further understand the anatomical and technical key points of this procedure, and it may yet prove to be a useful addition in the armamentarium in our battle against CLTI. Clinical Impact: Percutaneous deep venous arterialisation provides another option in the treatment of challenging "no-option" CLTI patients, and off-the-shelf devices will allow this procedure to be performed in centers where dedicated devices are not available.
