Abstract
Visceral artery aneurysms (VAAs) are rare, usually asymptomatic and incidentally discovered during a routine radiological examination. Shared guidelines suggest their treatment in the following conditions: VAAs with diameter larger than 2 cm, or 3 times exceeding the target artery; VAAs with a progressive growth of at least 0.5 cm per year; symptomatic or ruptured VAAs. Endovascular treatment, less burdened by morbidity and mortality than surgery, is generally the preferred option. Selection of the best strategy depends on the visceral artery involved, aneurysm characteristics, the clinical scenario and the operator's experience. Tortuosity of VAAs almost always makes embolization the only technically feasible option. The present narrative review reports state of the art and new perspectives on the main endovascular and other interventional options in the treatment of VAAs. Embolization techniques and materials, use of covered and flow-diverting stents and percutaneous approaches are accurately analyzed based on the current literature. Visceral artery-related considerations and targeted approaches are also provided and discussed.

Abstract
PURPOSE To evaluate the efficacy and safety of covered stent placement for the treatment of hepatic artery pseudoaneurysm (HAP). METHODS Between March 2006 and March 2019, 17 consecutive patients underwent emergency covered stent placement for treatment of HAP. There were 12 men and 5 women aged 24-71 years, with an average age of 49.4 years. Eleven patients had undergone Whipple procedure, 3 had hepatic abscess following hepatectomy, 2 had undergone hepatectomy under extracorporeal circulation, and 1 had received surgical exploration after a car accident. The average interval from surgical intervention to massive bleeding was 15.3 days (range: 6-35 days). After HAP was confirmed by angiography, 1-3 covered stent grafts (3-8 mm in diameter and 13 mm-5 cm in length) were implanted. Adequate drainage, anti-infection treatment, and symptomatic treatment were offered after stent placement, and no anticoagulation or antiplatelet drug was used. RESULTS The interventions were successful in all 17 patients. Angiography revealed pseudoaneurysms in common hepatic artery in 16 patients (in gastroduodenal artery stumps in 4 patients) and hemorrhage from a ruptured right hepatic artery in 1 patient. All patients were successfully implanted with 1-3 covered stent grafts. Bleeding was completely controlled in 12 patients (stent diameter: 4.5-8 mm). Four patients (stent diameter: 3-4.5 mm) experienced bleeding recurrence 1 h to 3 days after stent implantation, and type 1 endoleaks were identified during second angiography. Finally, these 4 patients died of multiple organ failure 2-10 days after embolization/blockage. The remaining patient suffered from abdominal hemorrhage again 2 weeks after stent implantation, and second angiography showed hemorrhage from a branch of the superior mesenteric artery; no bleeding occurred after embolization. Thirteen patients survived at discharge, and the average length of hospital stay was 26.53 days (range: 11-58 days). The average follow-up time was 23 months (range: 16-37 months), during which 6 patients died of tumor progression. No bleeding recurred during the follow-up period, and routine color Doppler ultrasound revealed that the common hepatic artery was patent and the blood flow was smooth at the stent implantation site. CONCLUSION Covered stent placement is a safe and effective alternative for treating HAP patients with high risk of severe complications after hepatic artery embolization. Larger stent grafts (> 4 mm in diameter) may achieve better prognosis.
