Chemoembolization Via Branches from the Splenic Artery in Patients with Hepatocellular Carcinoma
- Seoul National University College of Medicine, Department of Radiology (Korea, Republic of)
Purpose: This study was designed to evaluate the radiologic findings and imaging response of chemoembolization via branches of the splenic artery in patients with hepatocellular carcinoma (HCC). Methods: From January 2001 to July 2010, we observed tumor staining supplied by branches of the splenic artery in 34 (0.6%) of 5,413 patients with HCC. Computed tomography (CT) scans and digital subtraction angiograms of these patients were retrospectively reviewed in consensus by two investigators. Results: A total of 39 tumor feeding-vessels in 34 patients were identified: omental branches from the left gastroepiploic artery (n = 5), branches from the short gastric artery (n = 9), and omental branches directly from the splenic artery (n = 25). Branches of the splenic artery that supplied tumors were revealed on the celiac angiogram in 29 (85%) of 34 patients and were detected on pre-procedure CT images in 27 (79%) of 34 patients. Selective chemoembolization was achieved in 38 of 39 tumor-feeding vessels. Complete or partial response of the tumor fed by branches of the splenic artery, as depicted on follow-up CT scans, was achieved in 21 (62%) patients. No patient developed severe complications directly related to chemoembolization via branches of the splenic artery. Conclusions: Omental branches directly from the splenic artery are common tumor-feeding vessels of the splenic artery in cases of advanced HCC with multiple previous chemoembolizations. Tumor-feeding vessels of the splenic artery are usually visualized on the celiac angiogram or CT scan, and chemoembolization through them can be safely performed in most patients.
