1/136. Solitary hepatic hemangioma in a newborn infant complicated by cardiac failure, consumption coagulopathy, microangiopathic hemolytic anemia, and obstructive jaundice. Case report and review of the literature.A newborn infant with a large hepatic hemangioma developed congestive heart failure, consumption coagulopathy, microangiopathic hemolytic anemia, and obstructive jaundice. The patient was mildly heparinized (250 units per kg and day) and underwent successful resection of the tumor without lobectomy at the age of 3 days. blood volume increased from 93.9 ml/kg at the age of 5 h to 124.2 ml/kg prior to surgery. Red-cell mass simultaneously decreased from 53.8 to 39.4 ml/kg. The increase of blood volume is explained by congestive heart failure, the decrease of red-cell mass by intravascular coagulation within the tumor resulting in formation of thrombi and microangiopathic hemolytic anemia. A review of the literature on infants with symptoms caused by an intrahepatic hemangioma during the first month of life confirms that surgical intervention is the treatment of choice for infants with giant solitary hemangioma of the liver.- - - - - - - - - - ranking = 1keywords = consumption coagulopathy, coagulopathy, intravascular coagulation, consumption, intravascular, coagulation (Clic here for more details about this article) |
2/136. Clinical experience with presumed hemangioma of the choroid: radioactive phosphorus uptake studies as an aid in differential diagnosis.A total of 27 cases of choroidal hemangioma was evaluated with radioactive phosphorus uptake studies. In each case the diagnosis of malignant melanoma was initially entertained, but the 32P test was unequivocally negative in every instance. follow-up studies in every case have supported the clinical diagnosis. In 22 patients, the lesion was treated with photocoagulation, and in every treated case the serous macular detachment disappeared. The importance of early and correct clinical diagnosis is stressed, since these are salvageable and potentially useful seeing eyes.- - - - - - - - - - ranking = 9.2423154988171E-5keywords = coagulation (Clic here for more details about this article) |
3/136. Transpupillary thermotherapy in the management of circumscribed choroidal hemangioma.PURPOSE: To report a case of circumscribed choroidal hemangioma effectively managed with transpupillary thermotherapy. METHOD: A 53-year-old man affected by extramacular circumscribed choroidal hemangioma had sustained a decline in visual acuity caused by subretinal fluid exudation into the macular area. Multiple attempts at treatment with scatter photocoagulation over the surface of the lesion for several years had been unsuccessful in reducing tumor-related exudation. The patient was examined on referral and underwent a single session of treatment employing transpupillary thermotherapy. The course of the lesion after treatment was documented with fundus photography and ultrasonography. RESULT: Complete atrophy of the choroidal hemangioma with resorption of subretinal fluid was documented over the 6 months after transpupillary thermotherapy, with improvement in visual acuity. CONCLUSION: Transpupillary thermotherapy is an effective alternative to conventional scatter photocoagulation or radiation therapy for precise ablation of circumscribed choroidal hemangioma.- - - - - - - - - - ranking = 0.00018484630997634keywords = coagulation (Clic here for more details about this article) |
4/136. Anaemia, thrombocytopenia and coagulopathy due to occult diffuse infantile haemangiomatosis of spleen and pancreas.Diffuse infantile haemangiomatosis of the spleen is a very rare lesion. Large haemangiomas may cause trapping of platelets and coagulation disorders known as Kasabach-Merrit syndrome. We here report the case of an infant with splenic and pancreatic haemangiomatosis presenting with life-threatening thrombocytopenia, anaemia and intravascular coagulation. diagnosis was hampered by reactive erythroblastosis and non-conclusive radiological findings. While treatment with corticosteroids was ineffective, administration of antithrombin iii improved coagulation parameters. After splenectomy the child recovered promptly and has remained free of disease for 3 years to date. CONCLUSION: Occult visceral haemangiomatosis without visible cutaneous haemangiomas should be included in the differential diagnosis of thrombocytopenia, anaemia and consumption coagulopathy. antithrombin iii treatment may be considered to overcome bleeding problems in patients with Kasabach-Merrit syndrome.- - - - - - - - - - ranking = 0.20455037195209keywords = consumption coagulopathy, coagulopathy, intravascular coagulation, consumption, intravascular, coagulation (Clic here for more details about this article) |
5/136. A case report: pregnancy complicated by blue rubber-bleb nevus syndrome.Blue rubber-bleb nevus (BRBN) syndrome, first reported in 1958 by Bean, manifests with multiple hemangiomas located in the skin and gastarointestinal tract. Characteristic laboratory data include chronic anemia with iron deficiency and consumption coagulopathy.

6/136. Isolated diffuse hemangiomatosis of the spleen with Kasabach-Merritt-like syndrome.AIMS: Diffuse haemangiomatosis of the spleen is a rare benign vascular condition occurring as a manifestation of systemic angiomatosis or, less commonly, confined to the spleen. It is sometimes accompanied by severe disturbance of blood coagulation. The goal of this study was to characterize an additional case of isolated diffuse haemangiomatosis of the spleen and to determine the histogenesis of this lesion which remains obscure. methods AND RESULTS: We describe a case of isolated diffuse haemangiomatosis of the spleen in which histological and immunohistological findings suggested the possibility of a malformative tumour-like lesion. The pathological cavernous vessels were distributed randomly through the red pulp, without continuity with sinuses. The endothelial cells expressed vimentin, factor viii related antigen and CD34, but not CD8. Some cells lining the sinus lumen expressed CD68, lysozyme and myeloperoxidase. In addition, trabecular veins presented with intimal thickening. These results allow making a diagnosis between diffuse haemangiomatosis and other tumours/tumour-like lesions of the spleen, especially littoral cell angioma, splenoma and peliosis. CONCLUSION: If diffuse haemangiomatosis is usually classified as a benign proliferation of endothelial cells, we suggest that diffuse haemangiomatosis, when confined to the spleen, could be a tumour-like vascular lesion. In this hypothesis, the aetiology may be hamartomatous or malformative as is suspected in arterio-venous haemangioma of the lower extremities. The histogenesis is still questionable and no definitive proof in favour of one or the other hypothesis has been reported.- - - - - - - - - - ranking = 9.2423154988171E-5keywords = coagulation (Clic here for more details about this article) |
7/136. hemangioma of the umbilical cord: stenotic change of the umbilical vessels.We report a rare case of an umbilical cord hemangioma diagnosed by ultrasound at 16 weeks of gestation. The umbilical cord consisted of a hemangioma nodule and pseudocysts near the placental insertion, a large gelatin-like swelling adjacent to the nodule on its fetal side, and a short normal part extending to the navel. At 17 weeks of gestation, this condition resulted in the intrauterine death of the fetus. Microscopically, there were communications between the capillary of the hemangioma and the umbilical vessels, verifying the origin of the tumor. Moreover, the umbilical vein and one of the arteries changed stenotically due to the intravascular proliferation of the hemangioma. These findings indicate the possibility of a pathological association between the umbilical cord hemangioma and fetal demise due to impaired umbilical circulation.- - - - - - - - - - ranking = 0.00019894695460349keywords = intravascular (Clic here for more details about this article) |
8/136. 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.- - - - - - - - - - ranking = 0.20171934111647keywords = consumption coagulopathy, coagulopathy, consumption (Clic here for more details about this article) |

10/136. Endoscopic neodymium:yttrium aluminium garnet (Nd:YAG) laser irradiation of a bladder hemangioma associated with Klippel-Weber syndrome.A case of endoscopic neodymium:yttrium aluminium garnet (Nd:YAG) laser coagulation of a bladder hemangioma associated with Klippel-Weber syndrome is presented. The patient presented with extensive nevus and swelling of the left lower limb since birth. She was diagnosed with Klippel-Weber syndrome by angiography at the age of 1 year. Gross hematuria had been observed since she was 1 year old and, in addition, endoscopic examination revealed diffuse bladder hemangiomas. At 8 years of age, gross hematuria became worse and gait disturbance also appeared. She was referred to the Department of urology at Tohoku University School of medicine for endoscopic treatment in June 1998. Under general anesthesia, the bladder was inflated with CO2 gas and the hemangiomas were coagulated by Nd:YAG laser photonic irradiation endoscopically. Gross hematuria was markedly improved immediately following this treatment. Klippel-Weber syndrome is a rather uncommon disease which shows various types of vascular anomaly and hypertrophy of the lower extremities. Three to 6% of the patients have associated bladder hemangiomas. Although Nd:YAG laser irradiation provides results superior to alternative therapy and is the preferred treatment for most patients with bladder hemangioma, in this case, hemangiomas are multiple and present the possibility of re-bleeding, therefore long-term and close follow up is important.- - - - - - - - - - ranking = 9.2423154988171E-5keywords = coagulation (Clic here for more details about this article) |
