Objective To explore the methods and the efficacy of endovascular repair of closed articular artery injuries.Methods The Endovascular repair was performed in 21 cases of closed articular artery injuries including injuries of brachial artery, femoral artery of the hip joint, iliac artery, popliteal artery, subclavian artery of shoulder joint, axillary artery, carotid artery from September 2009 to December 2014.The mechanisms of injuries included traffic accident, crush injury, firearm injury, blast injury, stab wound.The specific location, extent and range of the arterial lesions were determined by angiography intraoperatively, and the diameter and the length of the involved arteries were measured.Types of artery injuries included 3 patients of vascular contusion, 12 patients of partial rupture of artery, 5 patients with partial rupture of artery complicated with traumatic aneurysm and arteriovenous fistula, 6 patients of complete rupture of artery.The guide wire was delivered to the distal end of the lesion with the help of catheter and the "working wire"pathway was established.When arteries were damaged severely or complete rupture, the wire was difficult to pass through the injury section of vessel.The superficial arteries of distal side of damage location were punctured after local anesthesia or dissection such as dorsalis pedis artery, posterior tibial artery and radial artery.The injured arteries were linked with the technology of guide wire "realignment" or "capture".Crossarticular mesh bare stents were implanted through contralateral femoral artery or ipsilateral radial artery.The double-deck stent of the cross-articular mesh bare stentst or stent grafts could be used during the acute phase of haemorrhage.Single-deck stent was successfully applied in 9 patients, one of whom was combined with coil embolization.And double-deck stents in 11 patients and stent graft in 1 patients.Results All the 21 cases were treated successfully with endovascular repair without peiropeartive death and serious complications.All were followed up from 6 to 36 months and for an average of 12.7 months.There was no obviously abnormality in CTA.Angiography showed that the stent lumen was stenosis but not more than 50%, and balloon angioplasty was performed.No stent was found in fracture, displacement, deformation and there was no recurrence.Conclusion The endovascular repair for treatment of severe articular arterial injuries with cross-articular mesh bare stent is of less invasion, short performation duration and quick postoperative recovery.It is a simple, safe and effective therapy.
