View clinical trials related to Injury of Radial Artery.
Filter by:The radial approach for a coronary angiography has became popular in several centers because of its simplicity and fewer complications. The radial artery occlusion (RAO) is the main inconvenient and impose a limitation of future use of the radial artery as an access site for catheterization in the future. Several strategies have been used to decrease the incidence of RAO (heparin, patent hemostasis, etc). Nitrates in intra-arterial have been widely studied in prevention of this spasm. Current data show that nitroglycerin intra-arterial at the end of the procedure reduce the incidence of RAO. The hypothesis that use of nitroglycerin at the start of catheterization would have the same effect was not tested.
Primary percutaneous coronary intervention represents the gold standard for the treatment of ST-segment-elevation acute myocardial infarction. However, periprocedural bleedings are associated with an increased risk of mortality, re-infarction, and stroke. Although the prognostic value of access site related bleeding complications is still debated, transradial approach is associated with better short-term outcomes and reduced hospital stay as compared to transfemoral approach. The investigators aimed to compare transradial approach with transfemoral approach with systematic achievement of hemostasis by the implantation of a vascular closure device in a national multicentre randomized clinical trial.
The transradial route is used in 90% of the coronary angiograms performed at Oslo University Hospital (OUS), Ullevål. A compression device needs to be applied after the procedure to achieve hemostasis. Patients and staff will benefit from using a device that yields safe and painless hemostasis. Patients will be randomly assigned to receive either the standard compression device (control group, A) or a recently developed compression device (experimental group, B). The study will be designed as a non-inferiority, prospective randomized controlled trial, with outcome measures being patient comfort during compression time and complication rates. Complications that will be measured are radial artery occlusion (RAO) measured using ultrasound at a follow up visit. Hematomas or bleeds from the puncture site after application of the compression device will also be classified as complications. The aim of the study is to investigate whether the new device, RY-STOP is non-inferior compared to the standard device, when considering the outcome measures.
Trans-radial approach (TRA) has becoming popular and widely adopted over the last decade. However, radial artery occlusion (RAO) continues to be one of the limitation of trans-radial access and potentially limits the radial artery as an access site in the future. Several strategies have been used to decrease the incidence of RAO including the use of anticoagulation, maintenance of patency during hemostasis, or shortening the duration of compression. Currently, there is no data whether vasoactive pharmacological therapy such as nitroglycerin administered intra-arterially at the end of the procedure may reduce the incidence of RAO. It is hypothesized that the addition of nitroglycerin (nitric oxide donor) at the end of a TRA procedure may reduce the incidence of RAO.
The purpose of this study is to assess the feasibility of performing repetitive coronary angiograms via the radial approach
