Bilateral Transankle Intervention as a Critical Determinant of Successful Revascularisation in Complex Peripheral Arterial Disease
Abstract
Introduction: Establishing optimal vascular access sites is important for the procedural success of endovascular treatment (EVT) and the patient's comfort afterwards. Among the variety of vascular access sites, the transankle intervention (TAI) has been used more recently; however, there have been no reports of complex lower extremity arterial disease lesions treated with the TAI manoeuvre. Report: An 82 year old man with chronic limb threatening ischaemia in both lower extremities underwent EVT for bilateral long segment occlusion from the iliac arteries to the superficial femoral artery (SFA). The right posterior tibial artery was punctured under extravascular ultrasound guidance and a Parent Select 5082 guide sheath was inserted. The guidewire was manipulated under intravascular ultrasound (IVUS) guidance. When the first guidewire entered the subintimal space, the second guidewire was manipulated to advance through the intraplaque route, while monitoring it using IVUS. The intraluminal space of the right common iliac artery was reached by repeating these procedures. A self expandable stent was deployed in the external iliac artery and drug coated balloons were inflated from the common femoral artery to the SFA; good vascular patency and favourable blood flow were confirmed. Subsequently, a similar TAI procedure was performed from the left dorsalis pedis artery, and successful revascularisation was achieved from the left common iliac artery to the SFA. After revascularisation, the persistent pain disappeared in the right lower limb and the wound healed favourably in the left lower limb. Conclusion: In this case of complex chronic limb threatening ischaemia, the TAI strategy worked favourably for successful revascularisation. Transankle intervention can provide various advantages for successful EVT.
