Active clinical trials for "Hematoma"

The goal of this study is to determine the sensitivity, specificity, and positive and negative predictive values of the a portable near-infrared-based device (portable NIR-based device), the InfraScanner 2000™, to detect intracranial hematomas (epidural hematomas (EDH) and/or subdural hematomas (SDH)) in patients hospitalized at Mbarara Regional Referral Hospital (MRRH) who have sustained or who are suspected to have sustained head trauma.

Angiography or angioplasty are commonly now done through inserting the device through radial artery in hand i.e. trans-radial procedures. It is reported that between 2-30% of these procedures get complicated by radial artery occlusion (RAO) which limit future use of this site for similar procedures if needed. It is important to control the arterial bleeding after the procedure completion while maintaining radial arterial flow appears to be an important factor in reducing RAO (patent hemostasis). Currently the most frequently employed method for hemostasis following trans-radial procedures is a compression device (RCD) such as TransRadial Bands (TRB). But TRB takes hours to achieve hemostasis and causes discomfort to the patients and longer time to discharge. Hemostatic pads offer an alternative to RCD where overall compression time is inherently low and patent hemostasis can possibly be achieved. The combined use of TR band with a hemostatic device may allow ease of use with reduced hemostasis time. The trial aims to test the hypothesis that compared to TR band (TRB) alone, catecholamine chitosan-based pad (InnoSEAL hemostatic pad, InnoTherapy, Inc.) used in conjunction with TRB (InnoSEAL+TRB)is nearly as good as TRB alone in terms of the outcomes like RAO and hematoma.

This study compare general anesthesia versus locoregional anesthesia for evacuation of chronic subdural hematoma. Half of participant will be operated under general anesthesia, while the other half will be operated under locoregional anesthesia.

This research is about the use of subgaleal drains to prevent accumulation of blood under the skin in patients undergoing surgery to remove part of the skull(craniectomy) and its associated complications. There have been early research that shows usage of subgaleal drains maybe related to increase in complication rates after craniectomy. These complications include hydrocephalus (accumulation of fluid in the brain), new hemorrhages, infection and low blood pressure. The investigators are performing this research to determine which type of subgaleal drains would produce the least complications. With this knowledge, the investigators would be able to reduce the amount of complications for future patients that undergo surgery to remove part of the skull. The purpose of this study is to determine the rate of complications in the 3 different groups of patients using the different types of drains under the skin in surgeries that involve removal of part of the skull. All participants will undergo the required surgery to remove part of the skull (craniectomy). Participants will then be randomly assigned to either one of 3 groups which are the vacuum drain group, passive drain group or no drain group.Participants in the vacuum drain group will have vacuum drains inserted during the closing stage of the surgery. Participants in the passive drain group will have passive drains inserted during the closing stage of the surgery. Participants in the no drain group will have a drain inserted during the closing stage of the procedure but the drain will remained closed. Data will then be collected and analysed to determine if the type of drains influence the rate of complications in craniectomy

In this prospective, randomized, multicenter trial shall patients with chronic subdural hematoma (cSDH) recruited, who were surgically treated. Initially, we would divide the patients randomized into two groups: Patients with supervised blow-maneuver and without. After surgical treatment of cSDH with insertion of a subdural drain, one group would perform a supervised blow maneuver ("Valsalva maneuver") every hour for five minutes from 10:00 to 20:00. In the other group, the standard care would be performed. The subdural drain would be explanted 2days after operation and a postoperative CT scan would routinely be performed. After hospital discharge, the patient would be rechecked in an ambulant setting and would receive CT scan as clinical standard. Recurrence of hematoma is defined as recurrent hematoma which should be reoperated. After 3 and 6 months we would evaluate the outcome of patients.

Aim of the present study is to investigate the efficiency of adrenaline (epinephrine) used locally in reducing and avoiding post-operative formation of subcutaneous ecchymoses and hematomas, in comparison with traditional practice of hemostasis, and to assess improvement in the quality of life of subjects undergoing classic great saphenous vein stripping, who received or did not receive adrenaline as a local hemostatic.

Traumatic acute subdural haematomas (ASDHs) are common pathological entity in neurosurgical practice . The frequency of (ASDHs) has been proposed as approximately 10-20% of patients admitted with traumatic brain injury(TBI) .Approximately two -thirds of patient with TBI undergoing emergency cranial surgery have an acute subdural haematoma evacuated . Two common causes of traumatic ASDH: accumulation of blood around parenchymal laceration , usually frontal and temporal lobes and there is usually severe underlying brain injury .The second cause is surface or bridging vessel torn from cerebral acceleration - deceleration during violent head motion .

Spontaneous Coronary Artery Dissection (SCAD) is a rare and often misdiagnosed cause of Acute Coronary Syndrome (ACS) affecting predominantly young women without cardiovascular risk factors. The origin of SCAD remains uncertain but a strong and frequent association with Fibromuscular Dysplasia (FMD) has been recently reported based on imaging evidence only. The aim of our study is to assess the presence of FMD and its genetic determinants i in a sample for haematoma or spontaneous coronary artery dissection. From May 2016 to 2018 we plan to include prospectively and retrospectively 200 patients admitted for ACS with confirmed diagnosis of SCAD. This study will be conducted in more than 30 French interventional cardiology centers. Coronary angiograms or intracoronary imaging data will be reviewed by two experienced interventional cardiologist experts in SCAD diagnosis. For each patient a genetic analysis will be performed. A systematic screening for FMD will be realized by computed tomographic or MRI angiography of renal, cerebrovascular and iliac arteries and reviewed by two experienced radiologists. A one year follow-up is expected. This study aims to confirm the presumed association of FMD and SCAD through the exploration of several artery beds and the study of confirmed genetic determinants, which has never been described previously to our knowledge.
