Objective. To investigate the efficacy and safety of endovascular double-layer bare stent placement for the treatment of traumatic false aneurysm (TFA). Methods. This is a retrospective review of five patients with TFA undergone double-layer bare stent placement in our center between February 2011 and August 2020. There are 2 males and 3 females aged 29-65 years, with an average age of 43 years. One case suffered from common carotid artery pseudoaneurysm, and four cases suffered superficial femoral artery pseudoaneurysm. Results. The endovascular interventional treatment was successful in all 5 patients, and the pseudoaneurysms disappeared after treatment. No TFA recurrence and no complications such as instent stenosis, stent migration, stent fracture, endoleak, and infection were observed during the 3-99-month follow-up period. Conclusion. For the treatment of TFA, endovascular interventional therapy with double-layer bare stent was minimally invasive, safe, and effective with fewer complications. It could preserve all branches of parent artery and had the advantage of lower cost. It can be used in the treatment of TFA in selected cases. However, further clinical researches with larger cohorts are needed before its long-term efficacy can be completely clarified.

“…HAAs account for 20% of all visceral aneurysms. With a poorly understood natural history, HAA is difficult to diagnose clinically [ 10 , 11 ]. The choice of treatment depends on the clinical presentation, associated risk factors, and general patient status, and vascular comorbidities should be considered, particularly in patients with arterial aneurysms.…”

Hepatic artery aneurysm (HAA) is a rare, yet clinically important, condition. While the causes of HAA are poorly understood, it is estimated that mortality following spontaneous rupture is as high as 40%. We discuss the case of a 77-year-old man who presented to our hospital due to a 10 mm pulmonary lesion in the left lower lung lobe, which was identified by a computed tomography scan of the lung at another institution. An examination with 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed in our department, but no significant uptake of 18F-fluorodeoxyglucose was found in the lung, and HAA was diagnosed only incidentally. A magnetic resonance imaging angiography supported the differential diagnosis of HAA, and the aneurysm was confirmed by targeted angiography. It was located in the common hepatic artery and was coiled during an intervention session. HAA accounts for 20% of all visceral aneurysms and, with a poorly understood natural history, is difficult to diagnose clinically, but early detection and treatment of HAA can improve prognosis.

“…In one meta-analysis evaluating 80 cases, 359 out of 2845 visceral aneurysms were hepatic (12%), with an incidence of 0.01 to 0.2% [3,6]. HAAs are approximately 20% of splanchnic aneurysms and are at risk of rupturing when diameter exceeds 2 cm [10][11] There have not been enough cases to determine the best way to repair them -i.e. open vs. endovascularly.…”

“…Definitive measures for intact or ruptured HAA, given the rarity of the disease, are not standardized [1,6,10]. However, it is reasonable to treat this pathology similar to an intact or ruptured aortic aneursym -decrease the shearing forces with beta-blockers.…”

Aneurysmal ruptures are a life-threatening pathology, and while the aorta is the principal location, any aneurysmal rupture can be fatal. Most result from chronic diseases, such as hypertension, diabetes, and vasculitis. Nevertheless, a rupture can result in acute decompensation and must be recognized and addressed quickly to limit morbidity and mortality. The authors describe a case of a 66-year-old female who presented to the emergency department (ED) for abdominal pain and syncope. Even though imaging did not explicitly show the specific site of rupture of the hepatic artery, the positive Rapid Ultrasound for Shock and Hypotension (RUSH) exam and aortic dissection on computed tomography angiography along with her clinical picture (hypotension, abdominal pain, decreased capillary refill, grey skin) raised our suspicions for critical pathology. Exploratory laparotomy revealed a ruptured hepatic artery aneurysm. Her hospital course was complicated by ischemic necrosis of the gallbladder, spleen, and liver, requiring cholecystectomy, splenectomy, and partial hepatectomy, but she was discharged to rehabilitation and expected to make a recovery. This case displays the importance of using ultrasonography early to aid in expedited diagnosis and treatment as well as maintaining a high suspicion for vascular pathology in the setting of hemorrhagic shock.
