Clinical Evaluation of the Treatment of Spider Angioma
Spider AngiomaTo evaluate the safety and effectiveness of the laser treatment for the treatment of spider angiomas.
A Prospective Controlled Study on Treatment of Giant Cavernous Hemangiomas of the Liver
Laparoscopic HepatectomyRadio-frequency Ablation2 moreIn the past, the investigators often treated giant cavernous hemangiomas of the liver by hepatectomy.Recently RFA and laparoscopic hepatectomy are also available and could be applied to cure this disease.But we can't get a clear answer about their effectiveness and safety. Hence the investigators conduct this study to explore the effectiveness and efficiency of the these two methods and compare their short to mid-term outcomes.
Tetracycline-Derivatives for Treatment of Cerebral Arteriovenous Malformations and Aneurysms
AneurysmsArteriovenous MalformationsThe purpose of this pilot study is to investigate the use of minocycline and doxycycline as medical therapy for inoperable or partially treated arteriovenous malformations (AVMs) and giant aneurysms.
CASH (Cavernous Angiomas With Symptomatic Hemorrhage) Trial Readiness
CCMCavernoma5 moreBrain Cavernous Angiomas with Symptomatic Hemorrhage (CASH) are rare, but they exact a heavy burden of neurologic disability from recurrent bleeding, for which there is no proven therapy. This trial readiness project aims to address current critical obstacles in identifying cases at multiple sites, characterizing their relevant features, and measuring their outcome. The timing cannot be more opportune, with therapeutic targets already identified, exceptional collaboration among researchers and with the patient community, and several drugs ready to benefit from a track to clinical testing in the next five years.
Surgical Management of Cerebral Arteriovenous Malformations Within Hybrid Operation Room
Intracranial Arteriovenous MalformationsTo evaluate the clinical benefits and risks of hybrid operating techniques in management of cerebral arteriovenous malformations.
A Randomized Trial of Unruptured Brain AVMs
Arteriovenous MalformationsCerebralThe purpose of this study is to determine if medical management is better than invasive therapy for improving the long-term outcome of patients with unruptured brain arteriovenous malformations.
Image Quality and Radiation Dose in Angiography
Arteriovenous MalformationsAneurysm2 moreClarityIQ is a novel X-ray imaging technology, that combines advanced real-time image noise reduction algorithms, with state-of-the-art hardware to reduce patient entrance dose significantly. This is realized by anatomy-specific optimization of the full acquisition chain (grid switch, beam filtering, pulse width, spot size, detector and image processing engine) for every clinical task individually. Furthermore, smaller focal spot sizes and shorter pulses are used, which are known to positively influence image quality . The final effect on the clinical image quality is investigated in this study.
Influence of MMP on Brain AVM Hemorrhage
Arteriovenous MalformationsCavernous Angiomas1 moreBrain vascular malformations, including arteriovenous malformations (AVM), cavernous malformations (CVM) and aneurysms, are a source of life-threatening risk of intracranial hemorrhage. The etiology and pathogenesis are unknown. There is no medical therapy presently available. Prevention of spontaneous intracerebral hemorrhage (ICH) is the primary reason to treat brain vascular malformations. The goal of this study is to: begin pilot studies to lay the groundwork for future clinical trials to develop medical therapy to decrease ICH risk. Matrix metalloproteinases (MMPs) regulate the extracellular matrix in association with various hemorrhagic brain disorders. MMP-9 has been most consistently associated with vascular wall instability and hemorrhagic brain disorders. Doxycycline, a non-specific MMP inhibitor, may enhance vascular stability, thus reducing the risk of spontaneous hemorrhage in brain vascular malformations by decreasing MMP-9 activity.
Timolol Option for Ulcerated Hemangiomas (TOUCH Trial)
Infantile HemangiomasThe 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.
Vascular Anomaly Pathology and Genomics Biopsy Study
Vascular MalformationsVascular Anomaly5 moreThe purpose of this research is to gather information on the safety and effectiveness of core biopsy of vascular anomalies for clinical pathology and clinical genomics studies.
