Long-term results of stent graft treatment of subclavian artery injuries: Management of choice for stable patients?

Purpose: To demonstrate our short and long-term results after transbrachial treatment of subclavian artery aneurysms and injuries with stent-grafts in elective and emergency settings. Methods: Ten of 12 consecutive patients (6 men; mean age 63.8 years, range 38–80) were treated electively with commercially prepared endografts delivered via a transbrachial access to repair a subclavian artery aneurysm (n = 3) or an injury from a misplaced central venous catheter (n = 7). Two patients required emergency treatment for a ruptured atherosclerotic aneurysm in one and an unintentional arterial puncture during placement of a central venous access in the other. Stent-graft patency during follow-up was assessed by physical examination with comparison of brachial blood pressures in all patients; computed tomography angiography (CTA) was performed in available patients. Results: Successful deployment of stent-grafts with sealing of the lesion was achieved in all cases. There were 2 (17%) procedural complications. One patient developed an access-site hematoma that required surgical revision. The second patient, who had a right subclavian injury, suffered an embolic cerebral infarction. The primary stent-graft patency during follow-up (mean 11.6 months) was 100%. CTA examinations in 7 patients at a mean 18 months showed strut dislocation at the thoracic outlet without luminal narrowing in 1 patient. A 50% intraluminal narrowing due to compression between the clavicle and the first rib occurred in another patient. Six patients with a mean follow-up of 23 months (range 0.3–4.5 years) are still alive with patent stent-grafts. Conclusions: Endovascular stent-graft treatment of subclavian artery aneurysms and injuries is a less invasive alternative to surgical repair. Long-term results must still be confirmed in further studies.

Aortic Injuries

Purpose: To evaluate the variations in aortic diameters and long-term results in patients who underwent thoracic endovascular aortic repair (TEVAR) for acute blunt traumatic thoracic aortic injuries (BTTAIs). Materials and Methods: We retrospectively evaluated 23 patients with a mean age of 39 years (range: 17-74 years) who underwent TEVAR for BTTAI between October 2000 and November 2014. All of the patients underwent computed tomography angiography (CTA) before hospital discharge as a baseline imaging for the subsequent follow-up examinations. The technical success, overall survival, and complications were evaluated. Furthermore, the aortic diameters outside of the stent-graft (1 cm proximal and 1 cm distal to the stent-graft) and the aortic diameters within the stent-graft (2 cm distal to the proximal end and 2 cm proximal to the distal end) were assessed. The diameters at baseline on CTA were compared with those of the latest available follow-up examination. Results: Technical success was 100% with a mean follow-up of 65.4 months (range: 12-171 months). No death was registered, and 2 (8.7%) of 23 endograft-related complications (1 stent-graft distal infolding and 1 endoleak 2 and 4 months after the procedure, respectively) were observed. An increase in aortic diameter either proximal or distal to the stent-graft (mean value 0.7 and 0.5 mm, respectively) or within the stent-graft (mean value of 0.5 mm for both proximal and distal diameters) was registered (mean follow-up at 65.4 months, range: 12-171 months). Conclusion: Aortic dilatation following TEVAR for BTTAI is minimal during long-term follow-up. Endovascular treatment represents a durable and safe option in acute BTTAIs.

Cystic Medial Necrosis

Purpose: To report the endovascular repair of rare true aneurysms of the subclavian artery in patients with degenerative connective tissue disorders. Case Reports: Two patients, one with Marfan syndrome and the other with idiopathic cystic medial necrosis, presented with 3 subclavian artery aneurysms. A Wallgraft and 2 Viabahn covered stents were used to successfully exclude these aneurysms. After 3 months, the Wallgraft thrombosed, but the contralateral Viabahn remained patent at the most recent examination 13 months after treatment. The other patient with the unilateral aneurysm had a patent Viabahn stent-graft at 10 months. Conclusions: Patients with degenerative connective tissue disorders may benefit from less invasive treatment with stent-grafts. The more flexible Viabahn stent-graft may be better able to adapt to arterial tortuosity. However, the long-term results of this new technique have not yet been established.
