Active clinical trials for "Hemangioma"

A new endovascular route for the treatment of brain AVMs may be possible in some cases: Trans-Venous Embolization (TVE). The technique uses microcatheters to navigate to the draining veins of AVM, to reach and then fill the AVM nidus retrogradely with liquid embolic agents until the lesion is occluded. This technique has the potential to improve on some of the problems with the arterial approach to AVM embolization, such as a low overall occlusion rate. However, by occluding the vein first, and filling the lesion with the embolic agent in a retrograde fashion, the method transgresses a widely held dogma in the surgical or endovascular treatment of AVMs: to preserve the draining vein until all afferent vessels have been occluded. Nevertheless, the initial case series have shown promising results, with high occlusion rates, and few technical complications. The method is increasingly used in an increasing number of centers, but there is currently no research protocol to guide the use of this promising but still experimental treatment in a prudent fashion. Care trials can be designed to offer such an experimental treatment, taking into account the best medical interests of patients, in the presence of rapidly evolving indications and techniques.

The aim of the study is to evaluate the efficacy and safety of sirolimus (oral form), to decrease the volume and symptoms due to superficial arteriovenous malformations (AVM). Sirolimus has properties that reduce the activity of the immune system (immunosuppressant), to fight against the proliferation of cancer cells (anti- tumor) and also reduce the proliferation of blood vessels (anti -vascular). Sirolimus is primarily used in transplant patients to prevent organ transplant rejection. Many animal and laboratory studies were carried out and demonstrate in particular the activity of sirolimus on vessels. It is this anti- vascular effect that could help treat arteriovenous malformations.

The purpose of this open-label study is to evaluate the safety and efficacy of cobimetinib in extracranial AVM.

The aim of this study was to evaluate the efficacy and safety of topical application of tacrolimus for superficial Kaposiform hemangioendothelioma (KHE) and tufted angioma (TA).

The objectives of this study and registry are to offer the best management possible for patients with brain arteriovenous malformations (AVMs) (ruptured or unruptured) in terms of long-term outcomes, despite the presence of uncertainty. Management may include interventional therapy (with endovascular procedures, neurosurgery, or radiotherapy, alone or in combination) or conservative management. The trial has been designed to test a) whether medical management or interventional therapy will reduce the risk of death or debilitating stroke (due to hemorrhage or infarction) by an absolute magnitude of about 15% (over 10 years) for unruptured AVMs (from 30% to 15%); and, b) to test if endovascular treatment can improve the safety and efficacy of surgery or radiation therapy by at least 10% (80% to 90%). As for the nested trial on the role of embolization in the treatment of Brain AVMs by other means: the pre-surgical or pre-radiosurgery embolization of cerebral AVMs can decrease the number of treatment failures from 20% to 10%. In addition,embolization of cerebral AVMs can be accomplished with an acceptable risk, defined as permanent disabling neurological complications of 8%.

Hepatic hemangioma is one of the most common benign tumor of the liver. Although the overall prognosis is good, active interventions are still needed in high-risk patients. Without specific drugs, the main treatment methods include surgical treatments, interventional therapies and radiotherapies. Effective medical treatments are needed urgently. Propranolol has achieved good results in infantile Facial/hepatic hemangioma, and shows some effectiveness in adult hemangioma. Here, investigators intend to evaluate the therapeutic effect of propranolol in adult hepatic hemangioma.

This clinical trial is to verify the safety and effectiveness of the Non-adhesive Liquid Embolic System(NALES) produced by Suzhou Hengrui Hongyuan Medical Technology Co., Ltd. in the process of clinical use to support the application of the National Medical Products Administration ( NMPA) product registration approval.

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.

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.

The purpose of this study is to assess the baseline sleep pattern disruption for patients starting oral propranolol at the standard BID dosing regimen compared to the control (timolol) group and to determine if there is a significant improvement in the sleep patterns in infants taking oral propranolol on the TID dosing regimen versus the control (timolol) group
