Cardiopulmonary Exercise Testing to Evaluate Pulmonary AVMs
Pulmonary Arteriovenous MalformationsHereditary Hemorrhagic TelangiectasiaPulmonary arteriovenous malformations (PAVMs) are a rare vascular condition affecting the lungs. PAVMs lead to low blood oxygen levels, yet are very well tolerated by patients. This study will examine the exercise capacity of PAVM patients using formal cardiopulmonary exercise tests performed on a stationary bicycle.
Comparative Study to Evaluate the Effectiveness of Atenolol and Propranolol in the Treatment of...
Infantile HemangiomaThrough this study, the investigators shall compare the effectiveness of atenolol with propranolol in the treatment of IH. In addition, the investigators shall try to elucidate the mechanism of action of beta blockers by assessing their action on triggers such as hypoxia. The study design will be a parallel group comparative study wherein patients of IH will be randomized into two groups. One group will receive propranolol and the other atenolol for a maximum period of 9 months. The patients will then be followed up regularly for regression of the IH based on Physician global assessment, hemangioma activity score(HAS), serial photography and lesional ultrasonography. Any side effects encountered during the treatment period will also be noted. Also serial measurements of hypoxia inducible factor 1 alpha(HIF-1α) will be made to ascertain the mechanism of action of the drugs.
Functional Magnetic Resonance Imagine(fMRI)Navigation in Intracranial Arteriovenous Malformation...
Intracranial Arteriovenous MalformationsLittle is known about the effect of fMRI navigation in the intracranial arteriovenous malformation surgery. The investigators aim to perform a multicenter prospective randomized single -blind clinical trial to assess the effect and safety of fMRI navigation in the brain arteriovenous malformation surgery.
Classical Procedure Versus Intrahepatic Glisson's Approach
Liver DiseasesLiver Neoplasms1 moreThe purpose of this research is to compare the classical procedure with intrahepatic Glisson's approach for laparoscopic anatomical hepatectomy. The validity, feasibility and limitations were assessed objectively through our clinical prospective study. The investigators expect laparoscopic anatomical hepatectomy with intrahepatic Glisson's approach is safe, effective and feasible.

Circumscribed Choroidal HaemangiomaThe aim of this study was to investigate the safety and effectiveness of application of intravitreal conbercept injection as the primary treatment for exudative circumscribed choroidal haemangioma.
CyberKnife Based Hypofractionated Radiotherapy for Vertebral Hemangiomas
Hemangioma of Vertebral ColumnClinical objective of the study is to compare the analgesic effect, toxicity and pathologic effect in the tumors of two radiotherapy schedules used for patients suffering from painful vertebral haemangiomas
Evaluation of the Efficacy of Captopril Versus Propranolol and Timolol as a Treatment of Infantile...
Infantile HemangiomaIs to compare and evaluate the efficacy of oral captopril with oral propranolol, intralesional propranolol injection, and topical Timolol in the treatment of infantile hemangioma and their effect on vascular endothelial growth factor and CD 133.
Research on Hybrid Operation Technique in the Treatment of Complex Brain Arteriovenous Malformations...
Cerebrovascular DiseaseArteriovenous Malformations1 moreComplex brain arteriovenous malformations (bAVMs) in ≥3 Spetzler-Martin grades have long been challenges among cerebrovascular diseases. None of the traditional methods, such as microsurgical operation, endovascular intervention, or stereotactic radiotherapy, can completely eliminate complex bAVMs without a risk of neural function deterioration. The multistaged hybrid operation solved part of the challenge but remained risky in the installment procedures and intervals. The one-staged hybrid operation was applied in the surgical treatment of cerebrovascular diseases and proved to be a potentially safe and effective method for curing complex bAVMs. However, lacking the support of high-level evidence, its advantages remain unclear. This study was proposed to validate the benefits and risks of one-staged hybrid operation in the treatment of complex bAVMs, as well as its indications, key technologies, and workflows.
Safety and Effectiveness of Intravitreal Conbercept for Exudative Circumscribed Choroidal Haemangioma...
Circumscribed Choroidal HaemangiomaThis prospective clinical trial aims to evaluate the safety and effectiveness study of intravitreal conbercept injection for exudative circumscribed choroidal haemangioma.
Evaluation of Lipiodol® Ultra Fluid in Association With Surgical Glues During Vascular Embolization....
Congenital HemangiomaHemangioendothelioma2 moreThis study is multicenter (up to 10 sites in India) 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.
