Abstract: Objective： To summarize the experience of endovascular treatment for isolated celiac trunk dilatation (ICTD). Methods： The clinical data of patients with ICTD, who was admitted during Jan.2012 and Jun.2015, were retrospectively analyzed. Detailed information of all the recruited patients was collected, including gender, age, comorbidities, initial symptoms, imaging examinations, endovascular treatment and its outcome, follow-up and survival status. Results： The study totally recruited 11 patients with ICTD and they were all diagnosed by computed tomographic angiography(CTA). Nine of them were diagnosed with celiac trunk aneurysm with a mean maximum diameter of (3.2±1.7) cm. The remaining two were diagnosed with celiac trunk dissection. The dissection was constrained in one case, while the dissection was anterogradely propagated to proximal common hepatic artery. Among the 11 cases, 9 were men and 4 were women. And the mean age was (54.5±12.4) year. The initial digital subtracted angiography (DSA) for celiac trunk and branch arteries was performed on all the patients so as to detect and confirm the blood supply of lesion and its lateral circulation. Finally, 4 patients were treated with coil embolization. And 2 patients received celiac artery stent implantation. Rupture of the abdominal aorta happened in 1 patient during the angiography. Although surgical operation was immediately carried out, the patient failed to survive eventually. And the remaining 4 patients were only treated with angiography. Ten patients were followed up. The mean follow-up time was 8.5 months. There was no abdominal symptom in all patients, and the blood supply of each branch was conducted well through main or lateral circulation during this period. Conclusions： ICTD remains uncommon. Endovascular treatment is effective and applicable for ICTD patients. The short term outcome is acceptable. Further follow-up is needed for long term outcome.
