Purpose The purpose of the study is to evaluate the initial and midterm efficacy and safety of endovascular treatment (EVT) using Viabahn stent-graft (SG) for arterial injury and bleeding (AIB) at the visceral arteries. Materials and methods Consecutive patients with visceral AIB who underwent EVT using Viabahn between January 2017 and February 2021 were retrospectively reviewed. Technical success, clinical success, peripheral organ ischemia, peri-procedural complications, bleeding-related mortality, 30-day mortality, neck length, re-bleeding, endoleaks, and patency of the SGs at 1, 3, 6, and 12 months were evaluated. Results EVT using Viabahn was performed in 14 patients (mean age: 68.6 years; 12 males) and 15 arteries. The technical and clinical success rates were 100%. The rates of peripheral organ ischemia, peri-procedural complications, bleeding-related mortality, and 30-day mortality were all 0%. The mean neck length was 9.9 mm. No endoleaks or re-bleeding occurred during the follow-up (mean: 732 days). The SG patency was confirmed after 1, 3, 6, and 12 months in 78.6%, 78.6%, 78.6%, and 56.1% of the patients, respectively. Conclusion EVT using Viabahn for AIB at the visceral arteries was safe and effective. SG occlusions without ischemia often occurred after 12 months.
