Certainty of Diagnosis • Uncertain diagnosis due to atypical features of imagings • Diagnosis of haemangioma was established by USG in 57%, by CT scan 73% of patients* • Red blood cell ( RBC ) or MRI scans regarded as the most accurate imaging tools *Yoon SS, Charny CK, Fong Y, Jarnagin WR, Schwartz LH, Blumgart LH, et al: Diagnosis, management, and outcomes of 115 patients with hepatic hemangioma.

Percutaneous Biopsy • Indicated in suspected malignant tumor • Risks: tumor rupture, intratumoral bleeding; seeding along the tract, intraperitoneal spread

Does size matter? • Benign natural course/ uncomplicated • Only 33 case reports of spontaneous rupture* • No malignant transformation • Follow up in 63 patients with giant haemangioma for 33 months**: no one develop new symptom or complication, 2 haemangioma increase in size; one by 1.1cm another by 3.6cm *Ribeiro AF M., et al.

Incapacitating Symptoms • 54% of patients were ultimately found to have other causes for their symptoms* • Causes: peptic ulcer disease, ischemic heart disease, gallstones or acidic reflux *Yoon SS, Charny CK, Fong Y, Jarnagin WR, Schwartz LH, Blumgart LH, et al: Diagnosis, management, and outcomes of 115 patients with hepatic hemangioma.

Complications • Spontaneous or traumatic rupture • 33 case reports of spontaneous rupture in adult, but the mortality rate is about 75%* • Kasabach Merritt Syndrome: consumptive coagulopathy • Malignant transformation has not been reported *Ribeiro AF M., et al.

Uncertain Diagnosis • Imaging: atypical appearance • High risks patients: History of colorectal cancer, HBV / HCV carrier • Resection is indicated in case of suspicion

Treatment Modalities 1. Surgery (Resection / Enucleation) 2. Radiation therapy 3. Embolization 4. Radiofrequency Ablation
1. Surgery Resection vs Enucleation
Resection vs Enucleation • Resection: Anatomaical & non-anatomatical • In 1988, Alper et al * described a new technique : Enucleation= dissect along the fibrous cleavage plane between the capsule of haemangioma and surrounding normal liver tissue • Avoid the need to resect normal liver parenchyma and minimize damage to blood vessels and bile ducts *Aydin Alper, MD; Orhan Ariogul, MD; Ali Emre, MD; Ali Uras, MD; Attila Okten, MD. Treatment of Liver Hemangiomas by Enucleation. Arch Surg. 1988;123(5):660-661.
Resection vs Enucleation Choice depends on certainty of diagnosis and anatomical considerations
Resection vs Enucleation Indications for Resection: • potentially malignant lesions • lesions that totally replace an anatomical section of liver • Deep seated lesions • Expectant difficulty to enucleate Indications for Enucleation: • indicated in anterior and peripheral haemangioma
Resection vs Enucleation *Susan M. Lerner, MD; Jonathan R. Hiatt, MD; Johanna Salamandra, RN, BSN. Giant Cavernous Liver Hemangiomas: Effect of Operative Approach on Outcome. Arch Surg. 2004;139:818-823. **Erhan Hamaloglu, Hasan Altun, Arif Ozdemir and Ahmet Ozenc. Giant Liver Hemangioma: Therapy by Enucleation or Liver Resection.

Ann R Coll Surg Engl. 2007 July; 89(5): 490–493
Resection vs Enucleation (Conclusion) • Enucleation is preferred when feasible, as it preserves hepatic parenchyma and minimizes complications. • Resection is reserved for lesions that cannot be enucleated safely.
2. Radiation Therapy • Indication: Diffuse, multiple, massive unresectable haemangioma with symptom or progression in size • Reductions in volume from 20-40%, with 30% improvement in symptomatology • Mechanism: provoke sclerosis of tumor parenchyma with subsequent reduction in size • Complication: hepatitis, centrilobular thrombosis, tumor rupture, malignant transformation*, SCC in kidney* *Michael J. McKay, Peter J. Carr2, Allan O. Langlands. Treatment of hepatic cavernous haemangioma with radiation therapy: case report and literature review.Aust N Z J Surg. 1989 Dec;59(12):965-8.
3. Embolisation Indication: - symptomatic giant haemangioma - complicated with coagulopathy - preoperative embolization * Result: reduction in tumor size**, symptomatology** correction of coagulopathy*** *Akamatsu N, Sugawara Y, Komagome M, Ishida T, Shin N, Cho N, Ozawa F, Hashimoto D.

Complications • Post-embolisation pain, fever, leukocytosis • Serious complications like infarction , intrahepatic abscess , sepsis are uncommon
4. Radiofrequency Ablation • Case reports of single or multiple electrode RF technology. • Mechanism: thrombogenic effect by damaging the layer of endothelial lining cause thrombosis • Complications*: ~2%, include infection, bleeding, injury to blood vessels, bile ducts, diaphragm, other abdominal organ * Ronald J.

Summary • Hepatic hemangiomas : Most common benign tumors of the liver • Mostly asymptomatic and uncomplicated • High accuracy of diagnosis by present imaging modalities • Asymptomatic or minimally symptomatic patients can be safely observed • Indications for resection of hepatic hemangiomas include severe symptoms, inability to exclude malignancy, and complications • Enucleation, when feasible, is the technique of choice for resection, and resection can be performed with minimal morbidity and rare mortality • Other treatment modalities need further studies to support its validity
