Filter by:The purpose of this study is to determine effect of combined medication of sufentanil and dexmedetomidine in patient controlled analgesia after neurosurgery.
This is an open-label whole-body PET/CT study for investigation of radiation dosimetry, plasma pharmacokinetics, biodistribution, safety and diagnostic performance of 68Ga-NEB in healthy volunteers and patients with suspected infection. Changes of routine blood and urine tests and any adverse events will be collected from the volunteers. Adverse events will also be observed in the patients.
Clinical 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
To searching the role of parecoxib sodium for postoperative pain management in open hepatectomy
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%.
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 study is to determine if Gadofosveset Trisodium (Gdfos, Ablavar) is a useful magnetic resonance imaging (MRI) contrast agent in accurately diagnosing liver metastases compared to the standard agent gadobutrol (EcGd, Gadovist).
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.
This register study will collect the treatment information of the intracranial arteriovenous malformation patients in China. We aim to understand the current treatment situation of the disease in China.
Cutaneous Arteriovenous malformations (AVM's) rare congenital high-flow vascular malformations in which arteries and veins are directly connected through a complex web of abnormal arteries and veins instead of a normal capillary network. Arterial feeders and enlarged draining veins directly connect through arteriovenous fistulas that create the "nidus". The natural history of AVMs is organized into a clinical staging system: during the first phase of quiescence, the arteriovenous malformation mimics a capillary malformation. After many years, the AVM may enlarge with loco-regional expansion and tissular destruction. At the ultimate stage, AVM may impact the heart function. They are considered non malignant but can expand and become a significant clinical risk when extensive. The management of these high flow AVM remains often problematic. Complete and large surgical excision of the nidus after hyperselective embolization is the only potential therapeutic solution but this, is often difficult if not impossible. There is no pathogenetic hypothesis for the development of these malformations. Histopathological examination (performed only on surgical resection specimen) is poor and does not provide sufficient evidence to assess the evolutivity or the severity of the MAV. Recent data hypothesize that these vascular malformations are associated with alterations of the vascular endothelium caused by genetic abnormalities involved in the control of angiogenesis and vascular homeostasis. The detection of these anomalies allows the search for cellular and genetic markers that might be useful to optimize the clinical classification, staging, predicting the evolution of these defects and some understanding of its pathophysiological mechanisms. To our knowledge, no studies to identify cellular markers / genetic and endothelial associated with the development of cutaneous AVMs have been published to date.
