“Beyond saving lives”: Current perspectives of interventional radiology in trauma

Figure 17 Peripheral vascular injury. A 56-year-old male with multiple rib fractures and neck swelling following road traffic accident. A: CT angiography showed two distinct pseudoaneurysms arising from the proximal right subclavian artery, one cervical and other intrathoracic (arrow). However, there was good opacification of distal subclavian artery with no disruption in continuity, ruling out transection (curved arrow); B, C: DSA corroborated CT findings and revealed two large pseudoaneurysms arising from the proximal right subclavian artery, lateral to the origin of thyrocervical branch (arrow); D: Subsequently, guidewire was manipulated across the PsA and covered stent graft (arrow) was deployed, excluding the origin of right common carotid artery. Post stenting angiography showed no opacification of pseudoaneurysm with good flow in distal subclavian artery; E, F: Follow up CT angiography done 2 wk later revealed both the pseudoaneurysm to be thrombosed. The stent (arrow) was optimally placed stent (arrow) with preservation of distal flow across it. PsA: Pseudoaneurysm; DSA: Digital subtraction angiography.
