1/31. Successful transcutaneous arterial embolization of a giant hemangioma associated with high-output cardiac failure and kasabach-merritt syndrome in a neonate: a case report.

    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.

2/31. High-output heart failure resulting from a remote traumatic aorto-caval fistula: diagnosis by echocardiography.

    Congestive heart failure (CHF) due to high output states is known to occur in a variety of systemic illnesses and in patients with arterial-venous fistulas. This paper reports the case of a 45-year-old man admitted to the emergency room with a diagnosis of new onset atrial fibrillation and CHF, whose past medical history was not significant except for a gunshot wound to his abdomen 22 years previously. The etiology of his CHF together with the cardiomegaly and hyperdynamic left ventricular systolic function was unknown. A subcostal view routinely done during transthoracic echocardiography revealed a severely dilated inferior vena cava and the presence of an aorto-caval fistula by color doppler. The patient underwent successful corrective repair with dramatic improvement in symptoms and resolution of the atrial fibrillation, and cardiac size returned to normal. This rare case emphasizes that patients with refractory CHF must be closely examined with particular attention to palpation and auscultation over all scars, irrespective of the duration since any traumatic or surgical event.

3/31. liver transplantation for hepatic arteriovenous malformation with high-output cardiac failure in hereditary hemorrhagic telangiectasia: hemodynamic study.

    We describe a case of orthotopic liver transplantation used as a therapeutic method to correct high output cardiac failure related to a liver arteriovenous fistula due to hereditary hemorrhagic telangiectasia. Detailed hemodynamic changes as they occurred during liver transplantation are described. ( info)

4/31. Prenatal evaluation of fetal neck masses in preparation for the EXIT procedure: the value of pulmonary Doppler ultrasonography (PDU).

    Sonographic demonstration of normal tracheal diameter and breathing-related lung fluid flow at 30 weeks' gestation in a fetus with a giant neck mass confirmed patent airways, thus avoiding an EXIT procedure. ( info)

5/31. Perioperative management of biventricular failure after closure of a long-standing massive arteriovenous fistula.

    PURPOSE: To report the perioperative management of arteriovenous fistula (AVF) closure in a patient with high-output heart failure and pulmonary hypertension. CLINICAL FEATURES: In a 71-yr-old man, closure of a long-standing massive AVF between the right femoral artery and vein was performed. After closure of the AVF, his pulmonary artery pressure (PAP) increased from 52/21 mmHg to 68/26 mmHg, his cardiac index decreased from 5.27 L.min(-1).m(-2) to 3.18 L.min(-1).m(-2), and his pulmonary wedge pressure increased from 15 mmHg to 32 mmHg due to an acute increase in afterload. Co-administration of prostaglandin E and a phosphodiesterase III inhibitor improved the cardiac index and the PAP. CONCLUSIONS: Surgical closure of the fistula may not always lead to resolution of the high output cardiac failure. In this case, afterload management using arterial dilators (prostaglandin E1, phosphodiesterase III inhibitor), use of inotropic drugs (phosphodiesterase III inhibitor), and close attention to volume status was crucial for a successful outcome after surgical AVF closure.

6/31. Prenatal sonographic diagnosis of klippel-trenaunay-weber syndrome with cardiac failure.

    This report describes the prenatal sonographic diagnosis of a case of klippel-trenaunay-weber syndrome. The sonographic appearance of this disorder was characterized by the presence of multiple distorted cystic areas involving the right leg and abdomen and cardiomegaly with early fetal heart failure. Despite the prenatal detection of the extensive cutaneous and visceral involvement, the infant died soon after birth of high-output cardiac failure and Kasabach-Merritt syndrome. ( info)

7/31. Crow-Fukase syndrome associated with high-output heart failure.

    A 64-year-old woman was admitted with systemic edema and exertional dyspnea. High-output heart failure was diagnosed by right heart catheterization and she was treated with diuretics. After 3 weeks, her symptoms disappeared but a high cardiac output state persisted. A diagnosis of Crow-Fukase syndrome was made based on the presence of polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes. Her serum vascular endothelial growth factor (VEGF) level was markedly elevated after recovery from heart failure. We suspect that an elevated VEGF level and a high cardiac output state may play a role in the pathogenesis of heart failure in Crow-Fukase syndrome. ( info)

8/31. Angiographic features of rapidly involuting congenital hemangioma (RICH).

    Rapidly involuting congenital hemangioma (RICH) is a recently recognized entity in which the vascular tumor is fully developed at birth and undergoes rapid involution. Angiographic findings in two infants with congenital hemangioma are reported and compared with a more common postnatal infantile hemangioma and a congenital infantile fibrosarcoma. Congenital hemangiomas differed from infantile hemangiomas angiographically by inhomogeneous parenchymal staining, large and irregular feeding arteries in disorganized patterns, arterial aneurysms, direct arteriovenous shunts, and intravascular thrombi. Both infants had clinical evidence of a high-output cardiac failure and intralesional bleeding. This congenital high-flow vascular tumor is difficult to distinguish angiographically from arteriovenous malformation and congenital infantile fibrosarcoma. ( info)

9/31. Congenital arteriovenous malformation of the finger resulting in cardiac decompensation: a case report.

    Congenital arteriovenous malformations of the hand may be hemodynamically significant in the neonate. Progressive cardiac decompensation is an indication for surgical intervention. The cause and classification of congenital vascular lesions of the hand are discussed. ( info)

10/31. High output cardiac failure caused by multiple giant cutaneous hemangiomas.

    A 59-year-old Chinese woman had multiple giant cutaneous cavernous hemangiomas on her right upper limb which resulted in high output heart failure because they presented as a large peripheral arteriovenous (A-V) fistula. Selective right subclavian arteriography showed extremely hypertrophic arteries of the patient's right arm with a tremendous blood supply to the soft tissues; neither superselective embolization nor surgery seemed applicable to this patient. The patient's heart failure was not satisfactorily controlled by conservative treatment. ( info)
