The aim of the present study is to analyze the feasibility and the impact of a two-step approach in the treatment of giant hemangiomas (GH) i.e., exceeding 10 cm in maximum diameter, consisting of transarterial embolization (TAE) followed by laparoscopic liver resection (LLR). Ten patients with 11 GH were treated with TAE and subsequent LLR between 2017 and 2020 (Group A). A matched cohort of 10 patients with GH treated with upfront LLR between 2014 and 2017 was identified for comparison (Group B). Data were analyzed regarding intraoperative and postoperative outcomes, including successful completion of LLR, morbidity, and mortality. Successful microparticle embolization of the GH-feeding arteries was performed in all patients in group A. In three cases a liquid embolic agent (Squid-18) was also injected to obtain complete embolization. No complications were observed after TAE. Successful surgery was performed after a mean time interval of 2.2 days from TAE without any case of conversion to laparotomy. Statistically significant differences between group A and group B were found in intraoperative blood loss (250 ± 200 vs. 400 ± 300 mL, p = 0.039), operative time (245 ± 60 vs. 420 ± 60 min, p = 0.027), and length of stay (5 ± 1 vs. 8 ± 2 days, p = 0.046). Our data suggest that two-step TAE + LLR might be a safe and effective option for surgical treatment of GH &gt, 10 cm.

Hepatic hemangioma (HH) is a congenital vascular anomaly comprising networks of abnormal blood and/or lymphatic vessels with endothelial cell proliferation. Their pathophysiology is not fully understood, and no specific drug is available to treat them. Conservative management, which limits observation, is preferred for most patients. A HH larger than 4 cm is considered a giant HH that may be treated using surgery ranging from embolization to hepatic resection or liver transplantation. Here, we describe a case with multiple and giant HHs that regressed significantly after treatment with azithromycin (AZM). A systematic literature review of HH and the effects of AZM on angiogenesis was then conducted.

Background Hepatic hemangiomas are the most typical benign mesenchymal lesions of the liver. Most of these lesions are asymptomatic. Giant hepatic hemangiomas (GHH) (>10 cm) are often symptomatic and require surgical intervention. This study aimed to describe the clinical findings, risk factors, diagnostic approach and management of GHH. Methods We performed a retrospective analysis of patients with GHH treated at our hospital from January 2008 to December 2018. The medical records of each patient were reviewed to obtain the clinical and surgical data. Results Twelve patients with GHH were treated during the study period. 9 were female and 3 were male. The mean age of diagnosis was 48,2 years. The most common presenting symptom was abdominal pain. Eight patients presented an abdominal mass. Indications for surgical resections were rupture (n = 2), Kasabach-Merritt syndrome (n = 1) and abdominal pain (n = 9). Right hepatectomy was done in four patients, left lobectomy in four patients, and enucleation in four patients. Embolization was performed in 4 patients, but due to the persistence of symptoms or bleeding, surgery was indicated. The mean operative time was 3.5 h, and median blood loss was 870 ml. The median hospital stay was 5.3 days. For four patients, we registered postoperative complications causing death in one case. All alive patients were asymptomatic at a median follow-up of 55 months. Conclusion Despite limitations and alternative modalities, surgery remains the only effective curative treatment for GHH., Highlights • Hepatic hemangiomas are the most common benign tumors of the liver with the incidence of 0.4–20%. • Giant hepatic hemangiomas (GHH) are usually responsible for overt clinical symptoms and complications. • Management of liver hemangiomas ranges from close observation to surgery depending upon the site, size and symptoms. • Surgical resection is indicated in patients with abdominal complaints or complications, or when diagnosis remains inconclusive.

Hemangiomas are the most common benign hepatic tumors and are usually asymptomatic. Lesions measuring more than 4 cm in diameter are known as “giant hemangiomas” and may cause various symptoms or complications depending on the size, the location, and the degree of compression of adjacent structures. Pulmonary embolism is a very rare complication of giant hepatic hemangiomas. In this case report, we describe a patient with acute pulmonary emboli, which presumably originated from laminar thrombi in the inferior vena cava caused by compression by giant hepatic hemangiomas.

We report a rare case of diffuse hepatic hemangiomatosis (DHH) of the left hepatic lobe coexistent with giant hepatic hemangioma and without extra-hepatic involvement in an asymptomatic adult patient. Liver hemangiomas are the most common benign liver tumors. However, DHH without extra-hepatic involvement has rarely been reported in adults. Furthermore, giant hepatic hemangioma coexistent with DHH is even uncommon, although an association between hemangiomatosis and giant hepatic hemangiomas may be supposed. In this peculiar case, we observed an exclusive and widespread involvement of the left hepatic lobe with a sharp boundary between normal and altered liver parenchyma running along Cantlie's line.

Minimally invasive laparoscopic resection has been used recently in liver surgery for treating selected hepatic hemangiomas. However, laparoscopic liver surgery poses the significant technical challenges and high rate of conversion. Radiofrequency (RF) ablation has been proved feasible in the treatment of hepatic hemangiomas with a size range of 5.0-9.9 cm. It is controversial to treat giant hepatic hemangiomas (≥10.0 cm) by means of RF ablation, due to the low technique success rate and high incidence of ablation-related complications. We aimed to assess the safety and efficacy of combined laparoscopic resection with intratumoral RF-induced coagulation for giant hepatic hemangiomas. Methods: We treated 2 patients with giant subcapsular hepatic hemangioma (12.0 cm and 13.1 cm in diameters respectively) by laparoscopic resection following intratumoral coagulation of the tumor with RF ablation. Results: Blood loss during resection was 100 ml (case 1) and 300ml (case 2) respectively. No blood transfusion and dialysis were needed during perioperative period. The two patients were discharged 6 days (case 1) and 12 days (case 2) after surgery without any complications, respectively. Postoperative contrast-enhanced CT follow up showed there was no residual tumor. Conclusions: It is feasible to treat giant subcapsular hepatic hemangioma by laparoscopic tumor resection boosted by intratumoral coagulation using RF ablation, which may open a new avenue for treating giant hemangioma.

Hemangioma is the most common benign tumor of liver and is often asymptomatic. Spontaneous rupture is rare but has a catastrophic outcome if not promptly managed. Emergent hepatic resection has been the treatment of choice but has high operative mortality. Preoperative transcatheter arterial embolization (TAE) can significantly improve outcome in such patients. We report a case of spontaneous rupture of giant hepatic hemangioma that presented with abdominal pain and shock due to hemoperitoneum. Patient was successfully managed by TAE, followed by tumor resection. TAE is an effective procedure in symptomatic hemangiomas, and should be considered in such high risk patients prior to surgery.

INTRODUÇÃO: Ruptura por hemangioma hepático é rara e há somente 32 casos descritos na literatura. RELATO DO CASO: Homem com 39 anos foi admitido com dor abdominal em hipocôndrio direito de início súbito associado à lipotímia. A investigação inicial demonstrou hemangioma hepático gigante (7x13 cm) em lobo direito associado a sinais de sangramento recente. Com o intuito de minimizar possibilidade de sangramento no intra-operatório, foi realizado embolização da artéria hepática direita. A operação transcorreu sem intercorrências, sem necessidade de hemotransfusão no intra-operatório. A transecção foi realizada com grampeador linear cortante de 75 mm. O tempo de internação foi de 13 dias. CONCLUSÃO: Procedimento cirúrgico é mandatório para hemangioma hepático roto, e a embolização é eficiente para controlar o sangramento e preparar melhor o paciente para a operação.BACKGROUND: Hepatic hemangioma rupture is rare and there are only 32 cases in the literature. CASE REPORT: A 39-years-old man was admitted for sudden severe upper abdominal pain. Examination revealed a giant liver hemangioma (7x13 cm) in right lobe of the liver with signals of recent bleeding. Large feeding artery was embolised to reduce bleeding risk. The surgery occurred without transfusion. The liver trans-section was done with 75 mm linear stapler. The patient was discharged in the 13th post-operative day. CONCLUSION: Surgery is mandatory in hepatic hemangioma rupture and embolization is efficient in controlling pre-operative bleeding giving better opportunity to successful surgical procedure.

El hemangioma hepático es el tumor benigno más frecuente del hígado. La gran mayoría de ellos son de pequeño tamaño, asintomáticos y con un pronóstico excelente. En raras ocasiones son de mayor tamaño y pueden estar asociados a una coagulopatía de consumo denominada síndrome de Kasabach-Merrit. Presentamos el caso de un paciente varón joven con un hemangioma hepático gigante y hemangiomatosis múltiple asociado al síndrome de Kasabach-Merrit.Hepatic hemangioma is the most frequent liver's tumor. The majority are small, asymptomatic and have an excellent prognosis. Those larger than 5 cm can be associated to a consumptive coagulopathy called Kasabach-Merrit syndrome. We present a patient with a giant hepatic hemangioma with multiple hemangimatosis associated to Kasabach-Merrit syndrome.

Hemangiomas are the most common benign tumors of the liver. Most of them remain stable. However, when a hemangioma continues to grow, it may become symptomatic. We describe a 40-year-old woman who initially presented with a hemangioma approximately 3 cm in diameter in the right lobe of the liver. Eight years after the initial presentation, the hemangioma had grown to 11 × 8 cm with the symptom of abdominal pain. She was managed with conservative treatment at another hospital. However, the symptoms and tumor bothered her physically and psychologically for 1 year. Surgical resection was performed to relieve her symptoms. The huge tumor was compressing the inferior vena cava and was very close to the middle hepatic vein, which made the operation difficult. The postoperative course was uneventful. We suggest early surgical resection for symptomatic giant hepatic hemangiomas. We also review reports in the literature about the treatment of symptomatic hepatic hemangiomas, including surgery, transcatheter arterial embolization and radiofrequency ablation.

Hemangioma is the most common benign tumor of the liver and it is often asymptomatic. Spontaneous or traumatic rupture, intratumoral bleeding, consumption coagulopathy, and rapid growth are mandatory surgical indications. We report a case of giant hemangioma of hepatic segments II and III, which presented as hemoperitoneum, and were treated successfully with preoperative transcatheter arterial embolization (TAE) and hepatic bisegmentectomy. A PubMed Medline search has identified up to now 32 cases of spontaneous rupture of hepatic hemangioma in adults (age >14 years) without a history of trauma, including the present case. Twenty-seven out of these were reviewed. Sixteen (84.2%) of 19 tumors of known size were giant hemangiomas (mean diameter 14.8 cm; range 6-25). Twenty-two (95.7%) patients underwent surgery. Thirteen patients (59.1%) had a resection, 5 (22.8%) were sutured, and 4 (18.1%) underwent tamponade. Three (23%) out of the 13 resected patients died. Four patients (30.8%) underwent TAE prior to elective hepatic resection without any operative mortality. Among the 5 sutured patients, 2 (40%) died as well as 3 (75%) out of 4 patients who underwent tamponade. The mortality rate of all surgery patients was 36.4% (8/22).

Hepatic hemangioma patients with Kasabach-Merritt syndrome have reportedly been cured by liver transplantation. However, liver transplantation as a potential cure for a stable patient without Kasabach-Merritt syndrome remains debatable. We report the case of a 27-year-old female patient with a giant hepatic hemangioma. The hemangioma measured 50 × 40 × 25 cm in size and weighed 15 kg, which is the largest and heaviest hemangioma reported in the literature. The patient showed jaundice, ascites, anemia, and appetite loss; but no disseminated intravascular coagulation was observed through laboratory findings. We successfully operated using a right lobe graft without the middle hepatic vein from a 55-year-old donor. At the long-term follow-up, the patient experienced two acute rejections, which were confirmed by biopsy. However, the patient still survives with good graft function after 50 months.
