    Abstract:
    OBJECTIVES: Axillary artery cannulation is commonly used in thoracic aortic surgery, often utilizing a sidearm graft. Although our institutional preference is femoral cannulation, we use axillary cannulation in select cases with a 'dirty' aorta on computed tomography scan or intraoperative transoesophageal echocardiography. Since 2011, we have routinely used an open Seldinger-guided approach for axillary cannulation. Here, we report our experience with open Seldinger-guided technique, evaluating its safety and efficacy. METHODS: A retrospective analysis of our institutional database from 2011 to 2016 was performed to find cases of peripheral arterial cannulation for thoracic aortic surgery. We identified 404 consecutive patients who underwent peripheral arterial cannulation. Of these, 352 were femoral and 52 were axillary cannulations. All axillary cannulations were performed for ascending and/or arch surgery. The technique involves a surgical exposure of the artery which is then cannulated by guidewire inside a purse string without arterial incision. RESULTS: Indications for surgery included aneurysm in 63.5% (33/52), dissection in 30.7% (16/52) and pseudoaneurysm in the remaining 5.8% (3/52). Hospital survival was 98.1% (51/52). There were no instances of axillary arterial injury or intraoperative malperfusion phenomena. No postoperative limb ischaemia or stroke was evident. No wound infections or late pseudoaneurysms were observed. CONCLUSIONS: The open Seldinger-guided technique for axillary artery cannulation is safe and effective. We strongly recommend this technique, given its speed and simplicity. The vessel is not snared, thereby preserving distal arterial flow and minimizing the risk of acute limb ischaemia. Furthermore, the limited manipulation of the artery lowers the risk of local complications.
