22 de septiembre de 2026 actualizado por: Liu Sheng, The First Affiliated Hospital with Nanjing Medical University

Acceso braquial versus femoral para colocación de stent en la arteria carótida: un ensayo clínico aleatorizado multicéntrico (BEFIT)

Study purpose:

A multicenter, prospective and randomized study is planned to compare the clinical outcomes of carotid artery stenting via brachial artery access and femoral artery access.

Eligible participants will be randomly assigned 1:1 to the brachial artery group or the femoral artery group.

Primary endpoint: surgical success rate.

Secondary endpoints:

  1. Operation time (time from first arterial puncture to last angiography)
  2. Serious adverse events (SAE) within 90 days;
  3. Access puncture complications;

Descripción general del estudio

Descripción detallada

With the improvement of treatment concepts and the continuous innovation of interventional devices/interventional technologies, neurointervention has become the preferred treatment method for many cerebrovascular diseases. Among them, the femoral artery is the most commonly used access, because the femoral artery is superficial, easy to touch, and the relatively large vessel diameter allows most neurointerventional surgeries to proceed smoothly. However, the femoral artery access also has the disadvantages of long bed rest time, exposure to private parts, and prolonged hospitalization.

Thanks to the great success of radial artery access in cardiac intervention, radial artery access is increasingly being used in neurointervention. However, due to the thin radial artery, there is a significantly increased risk of complications (radial artery spasm, radial artery occlusion) during large-cavity nerve intervention, and the operation time is significantly prolonged. Therefore, the overall proportion of neurointerventional treatment via radial artery access in clinical practice is less than 12%.

As the superior vascular trunk of the radial artery, the brachial artery has a larger diameter and is theoretically more suitable to replace the radial artery for large-bore intervention. Anatomically, the brachial artery is superficial and easy to touch in the antecubital fossa, and there are no important vessels and nerves in front of the blood vessel, and the posterior is the distal humeral platform, which is easy for brachial artery puncture and postoperative compression hemostasis. Studies have shown that thrombectomy for cerebral artery occlusion and carotid artery stent placement can be safely performed through the brachial artery. However, current studies are based on single-center small sample studies, and there is still a lack of large-sample randomized controlled trials to verify the safety and effectiveness of neurointervention via the brachial artery.

This study intends to conduct a multicenter, prospective, and randomized study to compare the clinical results of carotid artery stent placement via the brachial and femoral artery access.

Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Experimental: the brachial group

Patients with carotid artery stenosis will be randomly selected for carotid artery stenting via the brachial artery access.

CAS involves inserting a catheter or tube into an artery in the brachial or the femoral, and then threading the catheter through the arteries of the body to the location of the stenosis within the carotid artery in the neck. A stent is then placed in the stenosis and holds the artery open.

Comparador activo: the femoral group

Patients with carotid artery stenosis will be randomly selected for carotid artery stenting via the femoral artery access.

CAS involves inserting a catheter or tube into an artery in the brachial or the femoral, and then threading the catheter through the arteries of the body to the location of the stenosis within the carotid artery in the neck. A stent is then placed in the stenosis and holds the artery open.

X-ray exposure
Periodo de tiempo: 24 hours

X-ray exposure is defined as the duration and equivalent of X-ray exposure recorded by the DSA machine during operation.

Access conversion
Periodo de tiempo: 24 hours

If the randomized access was not successfully completed, switched to other access

24 hours
Degree of patient-reported comfort
Periodo de tiempo: 24 hours

The comfort scale adopts the simplified General Comfort Questionnaire (GCQ)developed by nursing expert Kolcaba. The scale is scored by level 1 to 4 Likert scale, with a score range of 28-112 points. The lowest score is 28 points and the highest score is 112 points. The higher the score, the higher the comfort. A total score of < 60 is low comfort, a total score of 60-90 is moderate comfort, and a total score of > 90 is high comfort.
