The value of 3D visualization operative planning system in ultrasound-guided percutaneous microwave ablation for large hepatic hemangiomas: a clinical comparative study

Background

To evaluate the value of a three dimension (3D)visualization operative planning system in ultrasound-guided percutaneous microwave ablation (US-PMWA) for large hepatic hemangiomas (LHHs).

Methods

Fifty-eight patients with LHHs were divided into 3D and 2D groups. The therapeutic efficacy was assessed by contrast-enhanced imaging during follow-up. Hepatic and renal function were examined. The complete ablation, tumor volume shrinkage, and complication rates were analyzed.

Results

The ablation time and energy of the 3D group were lower than those of the 2D group (1152.0 ± 403.9 s vs. 1379.7 ± 375.8 s and 87,407.2.9 ± 50,387.0 J vs. 117,775.8 ± 46,245.6 J, P = 0.031 and 0.021, respectively). The 3D group had a higher complete ablation rate than the 2D group (97.7 ± 2.4% vs. 94.5 ± 3.7%, P < 0.001). The incidence of hemoglobinuria after ablation in the 3D group was lower than that in the 2D group (32.0% vs. 57.6%, P = 0.047). The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and creatinine (Cre) after ablation in the 3D group were lower than those in the 2D group (126.7 ± 56.4 U/L vs. 210.9 ± 96.2 U/L, P < 0.001; 141.0 ± 60.8 U/L vs. 211.4 ± 90.0 U/L, P = 0.001; 57.3 ± 17.6 U/L vs. 80.8 ± 41.9 U/L, P = 0.010; and 66.6 ± 16.6 mmol/L vs. 84.5 ± 39.6 mmol/L, P = 0.037, respectively). There were no significant differences in antenna insertion and the volume reduction rate between the groups. One patient developed acute kidney injury shortly after ablation in the 2D group and recovered after hemodialysis. No other severe complications occurred during the follow-up period.

Conclusions

The 3D visualization operative planning system has a relatively high clinical application value in providing scientific, reasonable, quantifiable, and individualized therapy for LHHs by US-PMWA.

Obstructive jaundice caused by a giant liver hemangioma with Kasabach-Merritt syndrome: a case report

Hemangioma is the most common benign tumor of the liver. Liver hemangioma (LH) usually remains asymptomatic, but the most common symptoms associated with LH are abdominal pain and discomfort. LH is an uncommon cause of bile duct dilatation and obstructive jaundice. An 83-year-old Japanese woman who received hemodialysis at another hospital was referred to our hospital because of abnormal liver function and obstructive jaundice. Abdominal computed tomography and magnetic resonance imaging revealed a 13-cm tumor in liver segments IV–V and intrahepatic bile duct dilatation. Endoscopic retrograde cholangiopancreatography revealed extrinsic compression of the bile duct at the hepatic hilar region. Laboratory tests showed that the patient had low platelet counts and low fibrinogen levels. Because the patient had hyperbilirubinemia and Kasabach-Merritt syndrome, we performed a segmentectomy of liver segments IV and V. Histological examination showed hemangioma of the liver. The patient’s thrombocytopenia and coagulopathy improved immediately after surgery. In conclusion, LH is a very rare cause of obstructive jaundice. LH has the potential to compress the bile duct and cause obstructive jaundice.
