Evaluate the imaging characteristics of ruptured hepatocellular carcinoma and the effectiveness of embolization for controlling hemorrhage

SUMMARY

Objects: Evaluate the effectivenes of transcatheter arterial embolization for controlling arterial hemorrhage due to spontaneous ruptured hepatocellular carcinoma (HCC).

Methods: analyze retrospectively the outcomes of 22 patients who underwent abdominal CTscanner and urgent transarterial embolization for spontaneous ruptured HCC during the period from 01/2014 to 06/2016 in Viet Duc hospital.

Results: Mean tumor size: 83.95mm (longest diameter). 7/22 patients (31.8%) exhibited contrast extravasation on angiography, 2/22 patients (9.1%) exhibited pseudoaneurysm, one patient (4.6%) showed arterioportal shunt, 12/22 (54.5%) showed no vascular injury. The embolization materials we used mostly was Spongel in 19/22 patients (86.4%), histoacryl 3/22 (14.6%). The success rate of embolization on angiography is 22/22. The average volume of blood tranfusion was 969ml. 1 patient die in one months after the procedure due to liver failure. 6/9 (66.7%) patients with thrombosis of portal vein die in less than 6 months after procedure.

Conclusion: Transarterial embolization is a safe and effective method for controlling spontaneous rupture of HCC.

Key words: angiography, embolization, hepatocellular carcinoma, spontaneous rupture.
