Clinical Trial Summary

The Distal Radial Access (DRA) to the coronaries has emerged recently. It's done via the distal radial artery in the radial fossa, which is known as the snuff-box. The rationale of conducting this research is to assess this new access advantages and disadvantages, in comparison with the standard conventional forearm radial access and examine if it's worthy to be a future alternative method for coronary angiography. It aims to randomly compare between the new distal radial access via the snuffbox and the conventional forearm radial access for percutaneous coronary angiography and angioplasty procedures. The objectives of comparing both procedures are to analyze the frequency of complications in terms of occlusion, arterial spasm, hematoma, and to weigh accesses effectiveness in terms of time and attempts to puncture, crossover rate, procedure duration, hemostasis time, and convenience of the patients and operators. Candidates for coronary angiography are being randomized into the interventional group to undergo the angiography through the distal radial artery as the access site, or the control group accessing through the radial artery in the forearm. Procedural and post procedural outcomes and complications are being reported while patients are in hospital. All patients undergo doppler ultrasonography within 24 hours after the procedure.

Intervention

Procedure:
• distal radial artery access in coronary angiography and angioplasty
The patient grasps his thumb towards the palm to bring the radial artery up to the surface. The left hand is set on the right side of the groin toward the operator, who stands on the right side, with the dorsal surface of hand upwards. Afterward, the access site is disinfected, lidocaine HCL is SC injected for local anesthesia. Subsequently, the distal radial artery is palpated to find the point of the strongest pulse. Later, at a 45-degree angle, the artery is punctured with a 21-gauge needle and a 0.018 soft, flexible, metallic wire is then inserted in the needle. Through the sheath, 200 micrograms of Nitroglycerin is given. A 5000 unit of unfractionated heparin is administered through the IV line. A weight-adjusted dose of heparin is further added if PCI is needed. Then, a 0.035 wire is introduced in the sheath with other required instruments such as the intracoronary device and the catheters. After pulling out the sheath, a compression device, Safe Guard, is used for hemostasis.
• Forearm radial artery access in coronary angiography and angioplasty
The right hand is set in the anatomical position, with the anterior surface of arm face upwards. Afterward, the access site is disinfected, lidocaine HCL is SC injected for local anesthesia. Subsequently, the forearm radial artery is palpated to find the point of the strongest pulse. Later, at a 45-degree angle, the artery is punctured with a 21-gauge needle and a 0.018 soft, flexible, metallic wire is then inserted in the needle. Through the sheath, 200 micrograms of Nitroglycerin is given. A 5000 unit of unfractionated heparin is administered through the IV line. A weight-adjusted dose of heparin is further added if PCI is needed. Then, a 0.035 wire is introduced in the sheath with other required instruments such as the intracoronary device and the catheters. After pulling out the sheath, a compression device, TR band, is used for hemostasis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Radial artery occlusion	Doppler Ultrasonography of the radial artery for occlusions along its course, in both groups.	Within 24 hours after the procedure.
Secondary	Puncture Time	Which is time from first attempt to puncture to the successful one in seconds	During the procedure
Secondary	Puncture Attempts	Which is the number of puncture attempts from first one until the successful one (maximum 6)	During the procedure
Secondary	Procedure Duration	In minutes from the insertion of the sheath to its exertion.	During the procedure
Secondary	Radiation Duration	Which is measured by the radiological device in minutes.	During the procedure
Secondary	Radiology Dose	Which is measured by the radiological device in mGy.	During the procedure
Secondary	Compression "hemostasis" time	The time from the placement of the compression band until its removal (when there's no blood oozing after deflation), measured by minutes.	Up to 240 minutes after band placement
Secondary	Arterial spasm	Which is assessed by the operator if present or absent in terms of the difficulty in inserting the wire at the time of the procedures.; of the procedure.	During the procedure
Secondary	Hematoma and bleeding complications	It is defined by EASY hematoma scale.	Within 24 hours after the procedure
Secondary	Ischemic changes to the hand	It is noted by clinical features of pallor, absence of pulse, pain, cold, paresthesia or paralysis.	Within 24 hours after the procedure
Secondary	Crossover (failure to puncture)	It is transforming from the selected access to another after 6 failed attempts to puncture the first selected access	During the procedure
Secondary	Procedural pain	Assessed by numerical rating scale (NRS) for pain, which is an 10 point subjective scale (0-10) where 0 refers for no pain, 1-3 for mild pain, 4-6 for moderate pain and 7-10 for severe pain.	During the procedure
