Laparoscopic surgery for the treatment of a ruptured aneurysm of the right gastric artery: a case report

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.

Coil embolization of asymptomatic left gastric artery aneurysm: Case report and literature review

Patients with visceral artery aneurysms are rare, and the reported incidence of left gastric aneurysm (LGA) is only 4%. At present, although there is little knowledge about such disease, it is generally believed that appropriate treatment should be planned to prevent some dangerous aneurysms from rupturing. We introduced a case of 83-year-old patient with LGA who underwent endovascular aneurysm repair. The 6-month follow-up computed tomography angiography showed complete thrombosis in the aneurysm lumen. In addition, to insight the management strategy on LGAs deeply, a literature review concerning this entity published in recent 35 years was performed.

Single-Incision Laparoscopic Splenectomy for an Unruptured Aneurysm of the Splenic Artery

OBJECTIVE

We describe our experience of single-incision laparoscopic splenectomy (SILS) for an unruptured aneurysm of the splenic artery.

CLINICAL PRESENTATION AND INTERVENTION

A 73-year-old woman was diagnosed as having a splenic aneurysm which grew from 14 to 22 mm in diameter within 2 years. Due to a contrast agent allergy, transcatheter arterial embolization could not be performed; therefore, SILS was performed with a 4-cm Z-shaped incision. The operative time and intraoperative blood loss were 132 min and 27 mL, respectively. The patient was discharged 4 days after surgery.

CONCLUSION

In selected cases, SILS is a suitable and safe procedure for an unruptured aneurysm of the splenic artery.

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

•

We report here a rare case of intra-abdominal bleeding from a ruptured aneurysm of the right gastric artery.

•

Transcatheter arterial embolization (TAE) could not be adopted due to thrombotic occlusion of arteries, so we performed an urgent laparotomy.

•

We should not hesitate to convert endovascular approach into a laparotomy in an emergency situation.

Background

Visceral artery aneurysms at the origin of the gastric and gastroepiploic artery are uncommon. Raptured visceral aneurysms cause high mortality and require urgent and adequate intervention and treatment.

Presentation of case

A 65-year-old woman was transferred to the emergency department with sudden abdominal and back pain. Radiographically, we diagnosed intra-abdominal bleeding due to a ruptured aneurysm of the right gastric artery. Although her vital signs were relatively stable, transcatheter arterial embolization (TAE) could not be performed due to thrombotic occlusion of her abdominal aorta, and bilateral axillary arteries. She underwent an emergency laparotomy with ligation of the root of the right gastric artery and resection of the aneurysm, following which she showed good recovery. Histologically, the right gastric artery showed atherosclerosis with an organizing mural thrombus.

Discussion

Ruptured visceral aneurysms cause high mortality; therefore, rapid and adequate treatment is necessary. Achieving adequate transcatheter access might be difficult in some cases. In our case, we performed an emergency laparotomy and had good recovery.

Conclusion

We report and discuss the literature review for a rare case of intra-abdominal bleeding from a ruptured aneurysm of the right gastric artery which was difficult to be approache by TAE. In patients with unstable vital signs or in whom it is not possible to obtain a good laparoscopic view and clear operative field, we should not hesitate to convert the procedure into an open one, and perform an emergency laparotomy.
