Kasabach-Merritt syndrome is characterized by thrombocytopenia and bleeding tendency leading to disseminated intravascular coagulation with giant hemangiomas. We present a very low birth weight infant with this syndrome who underwent four operations. A male baby (1179 g, 37 cm) was born at a gestational age of 28 weeks and 6 days by caesarean section. A large hemangioma, 7 x 8 cm in size, was recognized on the left thigh. As associated consumption coagulopathy (Kasabach-Merritt syndrome) was diagnosed with platelet count 5.1 +/- 10(4) mm-3 and fibrinogen 49 mg.dl-1. Despite treatment with liniac X-ray radiation, systemic steroid and component transfusion, coagulopathy became worse with extremely low platelet count of 1.1 x 10(4) mm-3. Infusion of dopamine and dobutamine was necessary for high output cardiac failure. On day 9, PDA ligation was performed. Cerebro-ventricular drainage, ventricuro-peritoneal shunt and shunt revision were required on day 15, 49 and 88, respectively, for hydrocephalus due to intraventricular hemorrhage. Main anesthetics used were fentanyl and sevoflurane. Major problems encountered by anesthetists were: bleeding tendency, water and electrolyte management, body temperature control, and immaturity and fragility of premature infant. Coagulopathy in Kasabach-Merritt syndrome must be a risk factor for intraventricular hemorrhage, which is a characteristic complication of a very low birth weight infant.

Extensive haemangioma with platelet consumption (Kasabach-Merritt syndrome) is rare. The lesion is usually a single cutaneous cavernous haemangioma similar to that found in our patient. Multiple superficial strawberry naevi were also seen all over the rest of the body. This condition was diagnosed antenatally in this patient with the use of colour Doppler. There is one recent report where the thrombocytopaenia was diagnosed by cordocentesis. Unfortunately the baby developed heart failure with intractable coagulopathy and died 2 days later.

Hemangioma is a common hepatic lesion. The incidence is reported to be around 2%. The etiology of these lesions is unclear. Hemangioma should be regarded as benign with distinct clinicopathological features. Although most patients are asymptomatic, some may present with abdominal mass, cardiac failure, coagulopathy, or rupture. Hemangioma presents a diagnostic challenge. The surgeon should be aware of this lesion to avoid the pitfalls in differential diagnosis. A misinterpretation of hypervascular metastasis may lead to marked mismanagement. We emphasize the necessity of relatively specific and sensitive investigations in the differential diagnosis of a liver nodule. Surgery alone is usually unnecessary. Therapeutic options include steroids, hepatic artery ligation, therapeutic embolizations, radiation therapy, and chemotherapy. Available data suggest a favorable prognosis.

We report 2 cases of fetal heart failure associated with large placental chorioangiomas. One fetus exhibited serious hydrops on the initial fetal echocardiogram and was ultimately stillborn. The fetus in the other case exhibited cardiomegaly. Following the premature termination of the pregnancy, the fetus received medical treatment and recovered in 7 days. Monitoring the fetal cardiac size with ultrasonography is recommended to determine the optimal time of delivery in cases of large placental angioma that are diagnosed prenatally.

This report describes a female baby having a hemangioma over the right thigh that had appeared as an irregular bruise since two days old. Severe thrombocytopenia, consumptive coagulopathy, anemia, and heart failure developed at three months old. With a diagnosis of Kasabach-Merritt syndrome, systemic corticosteroid, vincristine, subcutaneous alpha-interferon, and massive plate transfusion were given. However, the platelet count remained low and the skin lesion enlarged gradually. Trans-feeding-arterial embolotherapy with a 5 ml pure ethanol (1 ml/kg) injection was performed at four months of age. Thirty days later, her platelet count recovered and the hemangioma shrunk in size. This case illustrates that absolute ethanol embolotherapy is an effective treatment for hemangioma with Kasabach-Merritt syndrome and may be life-saving for those with lesions refractory to medical therapy.

A 75-year-old man with a recent history of pulmonary embolism, presented with collapse followed by a gran mal seizure and right-sided non-pulsatile proptosis. On recovery, he had diplopia on lateral and upward gaze and signs of congestive cardiac failure. Further pulmonary embolism was proven by lung scintigraphy. Computed tomography of his orbits confirmed a contrast-enhancing space-occupying lesion of the medial wall of the right orbit, with no intracranial abnormality. The patient was investigated for metastatic tumour as a possible cause of the space-occupying lesion and the unprovoked thromboembolic event, but no evidence of malignancy was found. The orbital lesion was not biopsied because of the risk of bleeding from anticoagulation. Three weeks later, the patient represented with recurrent cardiac failure, proptosis, and diplopia. A transorbital ultrasound confirmed an encapsulated, well-defined vascular lesion, with typical appearances and Doppler flow characteristics of a cavernous haemangioma. Diuretic therapy abolished the proptosis and diplopia in tandem with relief of the cardiac failure. This is the first description of recurrent proptosis with diplopia due to recurrent congestive expansion of an orbital cavernous haemangioma.

We describe the case of a patient with a neonatal giant cutaneous hemangioma with high-output cardiac failure and Kasabach-Merritt syndrome and successfully treated with transcutaneous arterial embolization aimed at controlling severe congestive heart failure and consumption coagulopathy. A patient was admitted to the neonatal care unit on the first day of age because of a large hemangioma on his right lateral chest wall and respiratory distress, associated with cardiac failure resulting from arteriovenous shunting. On the second day of age the platelet count decreased to 5.7 x 10(4)/microliter and fibrinogen level was 85 mg/dl. The values of prothrombin time and activated partial thromboplastin time were prolonged. Intravenous predonisone therapy was started immediately, but bleeding tendency was getting worse and the evidence of congestive heart failure persisted. On the third day the patient then underwent embolization of feeding arteries with microcoils. The cardiac failure and thrombocytopenic coagulopathy had improved significantly without complications. We conclude that transcutaneous arterial embolization is an effective and safe treatment in this neonate and should be considered for the treatment of control high-output cardiac failure and coagulopathy in infants with hemangioma and Kasabach-Merritt syndrome.

We present a neonate with a cervicofacial haemangioma complicated by the Kasabach-Merritt syndrome, respiratory distress due to airway compression and high-output heart failure. This haemangioma and intravascular disseminated coagulation, treated initially by aspirin, ticlopidine and corticosteroids, required more invasive treatment with superselective embolisation and interferon alpha-2a. The clinical outcome was good.

We report a fetus with a giant neck hemangioma which was examined by MRI in utero. The initial diagnosis was made by ultrasonography. The sonolucent aspect of the mass, together with the presence of pulsating Doppler flow signals, was highly suggestive of a fetal hemangioma. In late pregnancy, fetal MRI revealed the location, size and characteristics of the neck tumor. Following prenatal corticosteroid treatment and premature delivery of the pregnancy due to fetal cardiac failure, the newborn received angiography and coil embolization of the tumor vessels. Despite vigorous treatments, the newborn died 12 h after birth. Evaluation of a fetal neck hemangioma by MRI is recommended late in pregnancy for precise information on the tumor and adjacent organs since the image is valuable for planning optimal perinatal treatment.

The use of helical CT, infusing pump and non-ionic contrast media has enabled the evaluation of different hepatic circulatory phases during contrast injection. Starting the acquisition of scans 20 to 30 seconds after the injection at a rate of 3 to 4 ml/sec the arterial enhancing of the liver is depicted. THROMBOSIS OR COMPRESSION OF THE PORTAL VEIN: Hypervascular triangle-shaped was with peripheral base can be seen, secondary to the increased arterial flow to compensate for the diminished portal flow. ARTERIOPORTAL SHUNTS: This condition can be caused by tumors such hepatocellular adenocarcinomas and hemangiomas, trauma, interventional procedures, cirrhosis, AVMs and surgery. INFLAMMATORY LESIONS: Hypervascular areas can be seen during the arterial phase in abscesses or cholecystitis, returning to their normal condition in the arterial phase. ANATOMIC VARIANTS: Third veins coming from the periphery (capsular veins, accessory cystic vein and an aberrant gastric vein) supply enhanced blood earlier than the portal circulation. OTHER CAUSES: In liver cirrhosis diffuse hyperattenuated areas can be seen during the arterial circulation. In right-sided heart failure, pericardial disease and Budd-Chiari Syndrome, "mosaic areas" can also be noted. In other patients these perfusion disorders were considered unknown. TUMORS: The well-differentiated hepatocellular carcinoma is a lesion with a predominant arterial blood supply, thus appearing in general hyperdense in this phase. Hemangiomas may appear as highly hyperdense lesions in the arterial phase and can be misinterpreted as HCC if smaller than 2 cm. (30% of cases). Focal nodular hyperplasia is a benign lesion (vascular malformation associated with focal nodules of hepatocellular hyperplasia) with increased arterial blood supply. Hepatic adenomas show an important hypervascularity during the arterial phase and, if large, they may present a small central scar and or capsule. Low or high-grade dysplastic nodules can sometimes be seen as hypervascular areas during the arterial phase. Although most metastasis are depicted as hypodense lesions sometimes they can show arterial hypervascularity such as carcinoid and pancreatic islet cell metastasis.
