A rare case of spontaneous rupture of an aneurysm of the right gastric artery

Spontaneous rupture of Gastroepiploic artery aneurysm in a young female: A case report

Gastroepiploic artery aneurysms (GEAAs) are rare subtype of Splanchnic artery aneurysms (SAAs) with estimated prevalence of 0.4% out of total SAAs. Most common causes include atherosclerosis, trauma, vasculitis, infections, pancreatitis, biliary diseases etc. GEAAs are more common in male and the rupture occurs usually after 50 years. Spontaneous rupture of GEAAs in females are rare and very less cases have been reported till now. A 35 years old female with no significant past medical history and no history of trauma presented to ED with features suggestive of shock. CECT (axial and coronal plane) revealed a focal outpouching in right gastroepiploic artery with evidence of active contrast extravasation suggestive of spontaneous rupture of Right Gastroepiploic artery aneurysm. Patient was resuscitated and Exploratory Laparotomy along with ligation and aneurysmectomy. Spontaneous rupture of GEAAs in young female is very rare. Urgent treatment is needed in case of unstable patients because of high risk of rupture and higher mortality rates of GEAAs.

Presentation of unruptured right gastric aneurysm due to segmental arterial mediolysis resected laparoscopically: A case report

INTRODUCTION

Timely diagnosis and treatment of intra-abdominal arterial aneurysms before rupture are highly recommended. We successfully prevented rupture through arterial aneurysm excision, highlighting the importance of the lack of reports on resection before rupture.

CASE PRESENTATION

A 60-year-old male with previous history of ureteral stones presented complaining primarily of left-sided abdominal pain. Computed tomography (CT) revealed a left ureteral stone and incidentally identified a submucosal gastric tumor and right gastric artery aneurysm, leading to referral to our department. Blood tests showed no abnormalities. CT revealed a 23-mm submucosal tumor protruding outward from the middle gastric body wall. A 13-mm aneurysm was observed in the right gastric artery, and no other aneurysms were detected, including intracranially. Upper gastrointestinal endoscopy revealed a smooth elevation covered by normal mucosa in the middle gastric body. Endoscopic ultrasound-fine needle aspiration resulted in a diagnosis of gastrointestinal stromal tumor (GIST) and surgery. We performed simultaneous surgery involving laparoscopic local resection of the gastric GIST and identification and excision of the right gastric artery aneurysm due to its enlargement (7 mm on CT conducted six years ago). The patient's postoperative course was uneventful, and he was discharged on postoperative day 6. Pathological examination confirmed a diagnosis of segmental arterial mediolysis.

DISCUSSION

Intra-abdominal arterial aneurysms affect approximately 1 % of the population. Splenic artery aneurysms are the most common at 58.7 %, whereas the gastric artery and gastroepiploic artery account for only 4.7 %.

CONCLUSION

Right gastric artery aneurysms are exceedingly rare, with no reported cases of successful resection before rupture.

Intraperitoneal bleeding from the right gastroepiploic artery by endoscopic ultrasonography: a case report

Objective: To describe the case of a patient with intraperitoneal bleeding from the gastroepiploic artery by endoscopic ultrasound who was successfully treated with transcatheter arterial coil embolization.

Patient and Methods: An 87-year-old man was referred to our hospital for examination of a gallbladder tumor. Endoscopic ultrasonography was performed using an oblique-view echoendoscope. After the endoscopic ultrasound, the patient went into shock. Computed tomography revealed a huge intraperitoneal hematoma and an aneurysm in the right gastroepiploic artery that were not seen on previous computed tomography images. Thus, urgent catheter angiography was performed, which showed a pseudoaneurysm of the right gastroepiploic artery and extravasation of the contrast medium from the pseudoaneurysm.

Results: Transcatheter arterial coil embolization was subsequently performed, and the bleeding stopped. Thereafter, his hemodynamics stabilized and his general condition improved. The patient was discharged 22 days post-treatment with an uneventful course.

Conclusion: Observation-only endoscopic ultrasound without invasive procedures can cause intraperitoneal bleeding due to a ruptured splanchnic artery. Thus, endoscopic ultrasonography should be performed more carefully in elderly patients.

Spontaneous Rupture of the Right Gastroepiploic Artery Immediately after Gastroscopy

Idiopathic spontaneous intraperitoneal hemorrhage is both rare and potentially fatal. The incidence of gastroepiploic artery rupture, especially a non-aneurysmal rupture, is extremely low. We report the case of an elderly woman who was mistakenly diagnosed with procedure-related bleeding after gastroscopy. A 0.3 cm polyp was identified and removed during the procedure. The patient later developed shock due to which gastroscopy was repeated; however, no unusual findings were observed. Therefore, abdominopelvic computerized tomography was performed and gastroepiploic artery rupture was detected. Transcatheter arterial embolization was immediately performed without laparotomy, without any complications. The bleeding was controlled, and the patient was discharged after embolization. It is important to acknowledge the possibility of spontaneous rupture of the visceral arteries in elderly individuals with hypertension or atherosclerosis, especially in the event of sudden abdominal pain or shock immediately after an endoscopic procedure. This is the first case report of idiopathic spontaneous rupture of the right gastroepiploic artery successfully managed by transcatheter arterial embolization in South Korea.

Successful transcatheter arterial embolization of a ruptured right gastroepiploic artery aneurysm: A case report

•

GEAAs are extremely rare.

•

We describe a case of a ruptured right GEAA treated by TAE.

•

An elderly woman with abdominal pain was diagnosed as having a ruptured right GEAA.

•

The patient was at high risk for surgery so we performed TAE for the ruptured GEAA.

•

The patient had an uneventful recovery and was discharged 10 days after TAE.

Background

Gastroepiploic artery aneurysms (GEAAs) are extremely rare. Ruptured GEAAs are related to high mortality and often treated by open surgery. We describe a case of a ruptured right GEAA that was successfully treated by transcatheter arterial embolization (TAE).

Presentation of case

An 80-year-old woman presented to the emergency department with sudden abdominal pain. We diagnosed her as having a ruptured right GEAA based on the contrast-enhanced computed tomography finding. We performed TAE for the GEAA after resuscitation. The patient had an uneventful recovery and was discharged 10 days after TAE.

Discussion

A ruptured GEAA causes high mortality; thus, immediate and adequate treatment is mandatory. Previously, many cases of successful surgical resections of ruptured GEAAs have been reported. In our case, we decided that the patient was not suitable for surgery because of her advanced age and bronchiectasis; therefore, we performed TAE and had a good outcome.

Conclusion

In patients at high risk for surgery, TAE can be an effective treatment for a ruptured GEAA.

A rare case of haemorrhagic shock secondary to spontaneous rupture of a branch of the left colic artery and the right gastric artery

Spontaneous splanchnic artery rupture is associated with up to 70% mortality. Affected vessels are often aneurysmal, secondary to atherosclerosis. We report, to our knowledge, the only case of spontaneous rupture of a branch of the left colic artery and the right gastric artery, possibly secondary to vasculitis.
