\[Background and Rationale\] Hepatic hemangioma is the most common benign tumor of the liver, with a reported prevalence of up to 20% in the general population. On B-mode ultrasonography, a typical hemangioma appears as a well-defined hyperechoic lesion compared with the surrounding liver parenchyma. However, hyperechogenicity is observed in only approximately 70% of cases, while the remaining lesions may appear hypoechoic or mixed echogenic. Additional sonographic features such as posterior acoustic enhancement or an echogenic rim may aid diagnosis, but none are specific to hemangioma. Consequently, contrast-enhanced CT or MRI is commonly required for definitive diagnosis, even when a hemangioma is strongly suspected on conventional ultrasound. In 2020, Kobayashi et al. (Ultrasound Med Biol 2021;47:941-946)reported a novel ultrasound finding termed the "fluttering sign," defined as continuous motion of tiny hyperechoic dots within a hemangioma during real-time scanning. Although the precise mechanism has not been experimentally validated, this phenomenon is presumed to reflect motion of acoustic scatterers, mainly red blood cells, induced by the ultrasound beam. The fluttering sign was observed in approximately 39% of hyperechoic hemangiomas and in up to 85% of hypoechoic or mixed-echoic hemangiomas, suggesting potential lesion specificity. A major limitation of the fluttering sign is its subjectivity, as visual assessment during real-time ultrasound is highly operator-dependent. To address this limitation, Imamura et al. (Sci Rep 2022;12:4701) developed a computer-based algorithm named Fluctuational Imaging (FLI), which objectively quantifies fluttering motion. FLI demonstrated almost perfect agreement with visual assessment of the fluttering sign (Cohen's kappa = 0.95). \[Study Objectives\] Although FLI is theoretically expected to be specific to hemangiomas, no study has systematically evaluated its behavior across a broad spectrum of non-hemangioma hepatic lesions. The primary objective of this study is to investigate whether the proportion of FLI-positive findings is significantly higher in hepatic hemangiomas than in non-hemangioma liver lesions. \[Risk-Benefit Assessment\] FLI is based on conventional diagnostic ultrasound physics and does not impose additional risk to patients. If FLI enables confident diagnosis of hepatic hemangioma using ultrasound alone, it may reduce unnecessary contrast-enhanced CT or MRI examinations, thereby decreasing healthcare costs, radiation exposure, and contrast-related risks. Overall, the anticipated benefits outweigh potential risks.
NCT02625389
This was a multicenter phase IV Post-Marketing Study. The study is designed to investigate the safety of Lipiodol® Ultra Fluid in association with surgical glues used according to each site medical practice of vascular embolization. Subjects will be enrolled with the main condition that a procedure of vascular embolization using Lipiodol® Ultra Fluid in association with surgical glues is part of their therapeutic/palliative strategy for their disease. The vascular embolization using Lipiodol® Ultra Fluid in association with surgical glue will be administered as study procedure. According to the patient need and health status a second vascular embolization using Lipiodol® Ultra Fluid in association with surgical glue may be considered by the investigator within the next 30 days after the first one. In this case, this procedure will be considered as a second study procedure. The per-procedure safety evaluation will be enabled by appropriate records of safety events during the time frame of the procedure of vascular embolization using Lipiodol® Ultra Fluid in association with surgical glues. Safety evaluation will be completed with safety records within 30 +/-3 days after the embolization procedure. Efficacy evaluation will rely on the level of lesion(s) obliteration after embolization compared to the pre-procedural target level of obliteration. Exploratory descriptive statistical methods will be used to evaluate safety and efficacy, using both the total population and subsets of subjects with similar clinical conditions.
NCT01764529
Cerebral cavernous malformations (CCMs) are clusters of abnormal blood vessels in the brain and spine. CCMs can bleed and cause strokes, seizures, and headaches. CCMs are often caused by an inherited gene mutation (alteration) in one of three CCM genes (CCM1, CCM2, or CCM3). There is a wide range of disease severity even among family members with this disease, though the natural history has not been clearly described for this particular population. This study will continue to enroll and follow participants with familial CCM to identify factors that influence CCM disease severity and progression, focusing on barriers to clinical trial preparedness. Our long-term goal is to identify measurable outcomes and robust biomarkers that will help select high-risk patients and help monitor drug response in future clinical trials. The specific goals of this study are to: * Identify factors that influence lesion progression to symptomatic hemorrhage and other outcomes, including quality of life; * Investigate the role of the gut microbiome and lesion burden in CCM disease, and * Identify blood biomarkers predictive of CCM disease severity and progression for clinical trials.
NCT01873131
The purpose of this study is to find out if pulsed dye laser treatment or timolol maleate 0.5% gel can help infants who have a hemangioma. The investigators also want to find out if pulsed dye laser treatment and timolol maleate 0.5% gel are safe to use without causing too many side effects. Hemangioma is a common type of birthmark. These birthmarks happen when many new blood vessels grow in a specific area on the skin. Blood vessels are tiny tubes that carry blood through the body. No one knows what causes blood vessels to group together. Most birthmarks don't hurt at all and they usually aren't a sign of any kind of illness. Lots of newborns have these birthmarks on their bodies, like between the eyebrows. These birthmarks usually disappear within the first few months to years of life. These birthmarks tend to disappear spontaneously. Most hemangiomas are not treated unless the hemangioma threatens the child's health, which occurs in about 1 in 3 children with hemagiomas. Pulsed dye laser is widely used in children, and is approved by the U.S. Food and Drug Administration (FDA) for treating hemangioma. The FDA has approved timolol maleate to treat glaucoma in adults, but the FDA has not approved timolol maleate to treat hemangiomas in children. About 7 infants with hemangiomas have received timolol maleate. The results so far show that timolol maleate may be helpful and safe in treating hemangiomas in infants. An important question being tested in this study is whether pulsed-dye laser or timolol maleate can prevent hemangioma from growing when used very early after birth.

NCT05106179
Spinal hemangioma is one of the most common benign vertebral tumours. Being mostly asymptomatic, it is still associated with a pain syndrome especially if encroaches into the neural canal. This study is organised to evaluate the efficacy and safety of β-blockers drugs in adults with spinal hemangioma.
NCT01010308
The purpose of this study is to explore the efficacy and safety of Nadolol in hemangiomas of infancy. The secondary objective is to assess the feasibility of conducting a randomized controlled trial comparing nadolol with corticosteroids and propranolol.
NCT01908972
The purpose of this study is to determine the safety and efficiency of Propranolol as an initial treatment for pediatric hemangioma.
NCT02731287
Infantile hemangioma (IH) is the most common benign vascular tumor in pediatric population. Oral propranolol is the treatment of choice for complicated hemangiomas. Topical timolol, a non-selective beta-blocker, is an emerging treatment which has been reported to be effective and safe for the treatment of IH, especially for superficial hemangiomas. Investigators hypothesize that treatment with topical timolol in the first two months of life, before the proliferative phase or in early proliferative phase, may prevent from further growing and the need to treat with oral propranolol.
NCT00466375
The purpose of this study is to determine if there are genes that are common in children with infantile hemangioma. This information will allow physicians to improve care for patients who have been diagnosed with this disease and to provide their parents with more complete information regarding the cause of this disease. This research is being done because many unanswered questions remain regarding children with infantile hemangioma. There are very few medications to treat infants with hemangiomas.
NCT00967226
Hemangiomas are relatively common lesions in infants. Most go away spontaneously after one year of life and do not need treatment. Others require treatment because they cause significant symptoms such as pain, or difficulty with breathing, eating or ambulating. Steroids have classically been used to treat hemangiomas and help to shrink them in 1/3 - 2/3 of patients. Unfortunately, steroids have many side effects in babies so physicians have sought other ways to treat them. Recently, the use of propranolol, a heart medication, was serendipitously found to reduce the size of hemangiomas. It appears to have many fewer side effects than steroids but it is not yet known if it works as well as steroids. This study seeks to compare the effect and the side effects of propranolol versus steroids for treating hemangiomas that cause symptoms in infants.
NCT01408056
The purpose of this study is to determine whether Timolol 0.5% Gel Forming Solution is safe and effective in promoting wound healing of infantile ulcerated hemangiomas compared with standard conservative management with topical antibiotic.
NCT00744185
The investigators observed that Propranolol, a beta-blocker commonly used in children was efficient to control the growth of alarming hemangiomas of the face. The primary objective of this study is to determine the efficiency of 1 month-early treatment of propranolol in infants aged less than 4 months affected by an hemangioma without any consequences on vital or functional structure and not justifying corticosteroids. The secondary objectives are: * the kinetic of the hemangioma evolution in infants treated by propranolol * Observance * Safety
NCT00374335
This study will attempt to determine how common liver hemangiomas are in children with infantile hemangiomas by comparing liver ultrasound results in patients with 1-4 cutaneous hemangiomas, 5 or more cutaneous hemangiomas, or at least 1 large hemangioma versus ultrasound results in children without hemangiomas. Other objectives of the study include identifying specific risk factors in patients who have liver hemangiomas and identifying risk factors in children with symptomatic liver hemangiomas.
NCT00490607
The purpose of this study is to investigate the pathogenesis of hemangiomas of infancy as they relate to normal pregnancies and those pregnancies complicated by placenta abnormalities. Women of all gestational ages will be enrolled in the study. Maternal serum, placental, and cord blood samples will be obtained for each subject. A medical history will be obtained for each subject. Post-delivery a member of the study team will perform a cutaneous exam of the infant to establish what birthmarks are present at birth. Mother will receive four phone call follow ups to determine if the infant has had any skin changes. If yes, mother will be asked to bring the child in for evaluation. If a hemangioma is diagnosed, a blood draw will be performed.
