Endovascular treatment of visceral artery aneurysms − case reports

Abstract

Introduction. Visceral artery aneurysms, including those affecting the splenic and hepatic arteries, rank among the most common types of abnormalities within the visceral arterial system. Treatment options for visceral artery aneurysms include open surgery and endovascular repair, with the latter being preferred for anatomically suitable and asymptomatic patients. Case Report. We present two cases, where the first concerns a 72-year-old male patient with an asymptomatic large common hepatic artery aneurism measuring 4.5 cm in maximum diameter. Computed tomography angiography revealed a 1.1 cm enlargement of the aneurism maximum diameter over a two-year period. The second case involves a 65-year-old female patient with asymptomatic splenic artery aneurism measuring 3.2 cm in maximum diameter. Both patients underwent endovascular stent deployment as part of their treatment regimen. No complications were observed during the early and late post-procedural phases. Follow-up imaging via control computed tomography angiography one month after the procedure revealed transparent stents in both cases without evidence of endoleaks. Conclusion. Endovascular stent deployment emerges as a safe and most efficient treatment modality for asymptomatic visceral artery aneurysms
