Duodenal Necrosis Associated with a Threatened Ruptured Gastroduodenal Artery Pseudoaneurysm Complicated by Chronic Pancreatitis: Case Report

Staged intervention in a patient with concomitant giant abdominal aortic aneurysm and hepatic artery

Abdominal aortic aneurysms are the most common types of aneurysms worldwide, whereas aneurysms in the blood vessels of the abdominal organs (splanchnic aneurysms) are rare. Few studies have reported cases of two giant aneurysms occurring simultaneously. Presented here is a case of a 67-year-old man who began to experience periumbilical pain with a diagnosis of a giant abdominal aortic aneurysm and a hepatic artery aneurysm. He was successfully treated using a staged endovascular stent grafting procedure. Postoperatively, the patient's abdominal pain was resolved, and he was prescribed medication for hypertension control, lipid control, heart rate control, antiplatelet therapy, and smoking cessation, which he took regularly. Follow-up evaluations were performed at 3, 6, and 9 months after surgery, and no late complications were observed. This case report suggests that when two giant aneurysms are diagnosed simultaneously, risk of rupture, surgical interventions, and postoperative complications are significantly increased. The choice of a treatment strategy is complex and has a high degree of individual specificity.

Gastroduodenal Artery (GDA) Pseudoaneurysm as a Cause of Massive Upper Gastrointestinal (GI) Bleeding Years After Partial Gastrectomy

Gastroduodenal artery (GDA) pseudoaneurysm is a rare complication of gastric and pancreatic surgery. The presentation is often severe gastrointestinal (GI) bleeding with up to a 90% mortality rate. Proper identification of past gastrectomy based on history or endoscopic appearance is essential for timely embolization or surgery, given that endoscopic management often fails. Here, we present a 65-year-old man who has a history of gastric ulcer-related surgery without clear documentation and hypertension presented with hematemesis, black stools, and syncope. Upper endoscopy showed signs of gastroenterostomy with stenosis and duodenal ulcer with spurting hemorrhage. Two days after endoscopic therapy, a recurrence of massive GI bleeding was noted. A celiac arteriogram was done by interventional radiology, demonstrating a pseudoaneurysm off the GDA. Successful embolization was performed with helical coils. The GI bleeding stopped, and the patient became stable after that. The GDA pseudoaneurysm-related bleeding should always be suspected in patients who underwent gastrectomy, bypass surgery, or pancreatectomy. Endoscopic interventions are usually temporary and sometimes can only give anatomical correlation before angiogram and embolization offer a definite treatment. Patients with GDA pseudoaneurysm can be entirely asymptomatic for a long time. The most common site of bleeding is the duodenum. Surgical interventions can also be offered if an angiogram is not successful in stopping the bleeding.

Case report: Duodenal obstruction caused by gastroduodenal artery pseudoaneurysm with hematoma: an unusual case and literature review

Visceral artery pseudoaneurysm is a rare disease that most commonly occurs in male patients in their 50s, with gastroduodenal artery (GDA) pseudoaneurysm accounting for only 1.5% of these. The treatment options generally include open surgery and endovascular treatment. In 40 cases of GDA pseudoaneurysm from 2001 to 2022, endovascular therapy was the mainstay of treatment in 30 cases, and most of them (77%) were treated by coil embolization. Our case report describes a 76-year-old female patient with a GDA pseudoaneurysm, which was treated by endovascular embolization using liquid embolic agent N-butyl-2-cyanoacrylate (NBCA) alone. This is the first time this treatment strategy has been used for GDA pseudoaneurysm. We demonstrate a successful outcome with this unique treatment. The successful experience of our case may provide a new treatment strategy for this rare disease.

Surgical repair of an emergent giant hepatic aneurysm with an abdominal aortic dissection: A case report

BACKGROUND

Hepatic artery aneurysm (HAA) is the second most common visceral aneurysm. A significant number of hepatic aneurysms are found accidentally on examination. However, their natural history is characterized by their propensity to rupture, which is very serious and requires urgent treatment. An emergent giant hepatic aneurysm with an abdominal aortic dissection is less commonly reported.

CASE SUMMARY

We report the complicated case of a giant hepatic aneurysm with an abdominal aortic dissection. A 66-year-old female presented with the complaint of sudden upper abdominal pain accompanied by vomiting. Physical examination showed that her blood pressure was 214/113 mmHg. Her other vital signs were stable. Computed tomography found a giant hepatic proper aneurysm and dissection of the lower segment of the abdominal aorta. Furthermore, angiography showed a HAA with the maximum diameter of approximately 56 mm originating from the proper hepatic artery and located approximately 15 mm from the involved bifurcation of the left and right hepatic arteries with no collateral circulation. Therefore, we decided to use a stent to isolate the abdominal aortic dissection first, and then performed open repair. After the operation, the patient recovered well without complications, and her 3-month follow-up checkup did not reveal any late complications.

CONCLUSION

Open surgery is a proven method for treating giant hepatic aneurysms. If the patient's condition is complex, staged surgery is an option.

Open Repair of Large Hepatic Artery Pseudoaneurysm Without Collateral Circulation: A Case Report

Hepatic artery pseudoaneurysm is a rare arterial disease. This case report describes a patient with hepatic artery pseudoaneurysm who presented with recurrent epigastric pain over a 4-month period. Computed tomography angiography (CTA) showed aneurysmal enlargement of the hepatic artery measuring 55 mm × 46 mm. The angiographic information is as follows: (1) the common hepatic artery originated from the superior mesenteric artery; (2) the proper hepatic artery originated from the common hepatic artery; (3) the proper hepatic aneurysmal disease had no collateral circulation. After careful consideration, the patient underwent an open surgical repair (OSR). The patient recovered well without any associated complications. The 1-year follow-up of patients did not reveal any relevant complications. The treatment choice, puzzles, and reflections of this case are all discussed in this article.
