Active clinical trials for "Hemangioma"

AVMs are abnormal collections of blood vessels which can occur in any part of the body including the lungs. These blood vessels are weakened and can rupture anytime causing bleeding which can be massive, leading to life-threatening conditions. Pulmonary AVMs occur in about 40% of patients with HHT. Each patient may have an average of 5 AVMs .Rupture of the AVM can lead to massive bleeding in the lung, stroke and infection of the brain. In order to prevent these complications, patients with HHT are routinely examined for pulmonary AVMs and treatment with embolization is recommended. AVMs have a main blood vessel or artery supplying blood to the collection of blood vessels. The way to treat AVMs is cut off their blood supply through a process called embolization. Embolization is a standard medical procedure which is done to stop or prevent hemorrhage (bleeding) from an AVM. It involves blocking the artery that supplies blood to the AVM by inserting a foreign body, into the blood vessel supplying blood to the AVM. Standard devices used for embolization include coils (made of stainless steel or platinum). These devices usually have a good success rate for blocking the artery that supplies blood to the AVM. However, a few AVMs that are embolized by standard devices may reopen over time. This is called reperfusion and will require repeat embolization procedures. For embolization of pulmonary AVMs at St. Michael's Hospital, the Nester coil is used. In this study, we would like to compare the Nester coil with a new coil device called the Interlock Fibered IDC Occlusion System. Both coils are approved for use in Canada, however the cost of the IDC coil limits its use at this hospital. Compared to the Nester coil, the IDC coils are made so that they can be removed or repositioned if they are not placed correctly. The coil also allows tighter packing which helps prevent reperfusion. This study will compare the success rate of embolization between the Interlock™ Fibered IDC™ Occlusion System (IDC coil) and the Nester coil.

OBJECTIVES: I. Evaluate the clinical efficacy of leuprolide, a gonadotropin-releasing hormone agonist (GnRHa), in treating infants with vision-endangering or large, disfiguring hemangiomas. II. Assess the impact of GnRHa on growth and development during infancy. III. Assess the safety of GnHRa in these patients.

Infantile hemangiomas are widespread vascular tumours having incidence of 10% and most of them involute spontaneously. However, they are known to be located in proximity of vital organs and can have poor cosmetic and functional sequel if left untreated. A wide range of treatment options are available from expectant therapy to radical surgical excision. Propanolol has also been shown to be effective in treating infantile cutaneous hemangiomas. Similarly, anti-metabolite drugs as bleomycin has also shown promising results. Efficacy in terms of reduction in size of both treatments has been scarcely studied especially in Pakistan. OBJECTIVE: To assess the efficacy of oral propranolol and intraleisonal bleomycin in the treatment of infantile cutaneous hemangioma in terms of size regression

We plan to conduct a study, to see how safe and effective timolol maleate 0.5% gel-forming solution is for infantile hemangiomas (IH) and the response of hemangiomas to timolol maleate 0.5% . Our hypothesis is that timolol will inhibit and possibly reverse growth of appropriate infantile hemangiomas.

The purpose of this study is to assess the efficacy and safety of oral propranolol versus nadolol in patients with Infantile Hemangiomas (IH) in a randomized, controlled, double-blinded study.

To evaluate the efficacy and safety of transcatheter arterial embolization with E7040 in Japanese subjects with hypervascular tumor or arteriovenous malformation

The purpose of this study is to assess the safety and efficacy of Timolol 0.25% and 0.5% doses.

Test whether AVMs treated with Onyx is equivalent to treatment with n-BCA. Success is defined as an AVM size reduction greater than 50%

Percutaneous sclerotherapy is currently a widely used treatment for subcutaneous low-flow vascular malformations. Considered as a low-flow vascular malformation, symptomatic liver hemangiomas could also theoretically be safely and effectively treated by percutaneous sclerotherapy with a mixture of Bleomycin and Lipiodol. The safety and efficacy of percutaneous sclerotherapy was firstly introduced by the investigator's investigators in 5 patients in a pilot study. The aim of this study is to design and conduct a study to evaluate the safety and efficacy of percutaneous sclerotherapy in a larger sample size with a long term follow-up.

The purpose of this study is to determine the safety and efficiency of Propranolol as an initial treatment for pediatric hemangioma.
