Filter by:The primary purpose of this study is to identify the clinical characteristics of infantile hemangioma (IH) in our single center in China. The second objective of the study is to identify the clinical features of infantile hepatic hemangioma (IHH) and ulceration in patients with IHs.
In the stage of randomized controlled study, our purpose is to obtain the Intraoperative anticoagulation program supported by evidence-based medicine.
In the stage of registration study, our purpose is to find out the safety range of activated coagulation time level in cerebral aneurysm and arteriovenous malformations with hybrid operation.
Rapid ventricular pacing (RVP) is a technique to obtain flow arrest for short periods of time during dissection or rupture of the aneurysm. RVP results in an adequate fall of blood pressure which presents as an on-off phenomenon. It is not clear whether repetitive periods of pacing are harmless for the patient. Silent cardiac and cerebral infarcts may be undetected. The investigator will study the safety of RVP, particularly for the heart and the brain, retrograde by studying troponin levels and magnetic resonance imaging or computed tomography.
This study compares the accuracy of fusion imaging (Fusion Roadmap) versus real-time X-ray imaging (Roadmap) during catheterization of supra-aortic trunks of in patients with aneurysms or arteriovenous malformations.
Through 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.
To evaluate the clinical benefits and risks of hybrid operating techniques in management of cerebral arteriovenous malformations.
Infant hemangioma(IH) is the most common benign vascular tumor of infancy with the estimated incidence varies 1% to 12%.However, in China, the incidence of infant hemangioma and related epidemiological data remains unclear. So, the investigators designed the study for the following purposes: 1, to aware the incidence of infantile hemangioma and understand the related risk factorsin China; 2, to understand the clinical characteristics of infantile hemangioma and the risk factors for complications; 3, to investigate the level of knowledge, treatment options in infant hemangioma in Chinese doctors; 3, to improve the awareness of infantile hemangioma in parents and provide more advice for pregnancy counseling and eugenics.
The controversy surrounding epithelioid hemangioma diagnosis stems from its somewhat aggressive clinical characteristics, including multifocal presentation and occasional lymph node involvement. The investigators reviewed the clinicopathologic and radiologic characteristics of bone and soft tissue epithelioid hemangioma in patients treated at our institution with available tissue for molecular testing. The hypothesis is that epithelioid hemangioma may present with multifocal involvement and rare loco-regional lymph node metastasis, but it remains a benign tumor with excellent prognosis.
Aim of this trial is to study the effect of Dexmedetomidine on post-operative blood pressure in patients undergoing brain arteriovenous malformation embolization. The patients were randomized allocated to either Dexmedetomidine group or Control group. Patients in Dexmedetomidine group will receive intravenous Dexmedetomidine while the control group will receive normal saline. Post-operative anti-hypertensive drug, Visual analogue score,post-operative analgesics consumption, Quality of Recovery score, Ramsay score, and adverse events were recorded.
