Giant celiac artery aneurysm: Treatment by transcatheter coil embolization

Endovascular treatment of a large saccular aneurysm of the celiac artery: a case report and review of literature

Celiac artery is a visceral abdominal vasculature whose aneurysms are very rare, accounting for less than 0.01% of all aneurysms. This condition can be treated by open aneurysmectomy or aneurysmorrhaphy and endovascular intervention. Due to the high mortality and morbidity associated with open surgery, endovascular intervention may be a better treatment option. Here, we present a case related to a 40-year-old man who had been experiencing vague epigastric pain for 4 months prior to admission and was managed endovascularly.

Successful endovascular treatment of a recurrent giant celiac artery aneurysm

Visceral artery aneurysms are very rare and aneurysms of the celiac trunk are the rarest ones: they are in most cases asymptomatic and their detection is frequently incidental. In this article we report the case of a man affected by severe abdominal pain with a huge aneurysm of the celiac trunk, first successfully treated with coil embolization, but, after 10 months, another endovascular embolization was required for deployment of the metallic coils previously released, ahead into the fund of the sac with recanalization of the aneurysm. A second endovascular treatment was performed with other coils and Amplatzer-Plug. The high risk of rupture makes treatment of such aneurysms mandatory and surgery is still considered the gold standard therapy of VAA, but, due to its high morbidity and mortality risks, in the last years, it has been widely replaced by endovascular embolization. An effective endovascular embolization requires not only the complete filling of the aneurysmal sac, but also the complete vascular exclusion of its in-flow and out-flow tracts, to reduce the risk of its anterograde or retrograde reperfusion.

Endovascular Treatment of a Dissected Celiac Trunk Aneurysm Complicated with Consequent Pseudoaneurysm: Primary Treatment and Treatment Relapse after 5 Years

We report on an asymptomatic 56-year-old male with incidental diagnosis of celiac trunk aneurysm, diagnosed during an ultrasound scan performed to control polycystic kidney disease. The CT scan revealed a 3.8 cm saccular aneurysm of the celiac artery dissected in the superior wall with a consequent 4.3 cm pseudoaneurysm; we adopted an endovascular approach to exclude the lesion by catheterizing the celiac trunk and positioning a vascular plug in the common hepatic artery and a covered stent in the splenic artery; finally we fulfilled the aneurysm sac with Onyx. 30-day control CT scan revealed procedural success. Five years later he came back to our department for an aneurysm relapse in the common hepatic artery. We performed a second endovascular approach with a superselective catheterization of the pancreaticoduodenal arcade in order to exclude the lesion with Onyx and microcoils. Nowadays the patient is in good clinical conditions. Endovascular approach is a valuable method to treat visceral aneurysms; however, long-term imaging follow-up is essential to monitor the risk of relapse.

CT imaging findings and endovascular management of isolated spontaneous dissecting aneurysm of celiac artery

Isolated spontaneous dissecting aneurysm of celiac artery without concomitant involvement of aorta is a rare entity and only a few cases are reported in the literature. More cases are being detected recently with greater advancements in CT technology. Clinicians and emergency physicians should be aware of this condition and should include it in the differential diagnosis of patients who present with refractory postprandial epigastric pain, particularly in middle-aged men. We present a case of a 45-year-old male with isolated spontaneous dissecting celiac artery aneurysm, with special emphasis on CT findings and the role of endovascular management.
