Objectives To investigate the clinical application value of coronary angiography (CAG) through radial artery way.
Methods Puncture point chose about 2–3cm near to the wrist transverse striation, and chose at the strongest arterial pulse. Seldinger’s method was used to puncture arterial pulse. After sucessful, 0.025-inche soft head straight steel wire was post in brachial artery, then 5F or 6F arterial sheath was inserted. Nitroglycerin 200 ug, Verapamil 2 mg and Heparin 2000 U were given through arterial sheath. Radial artery catheter, JR3.5–4.0, or JL3.5- 4.0 catheter were post in coronary openings to do left and right coronary angiography. After angiography, arterial sheath was removed immediatly and puncture point was done pressure dressing. Patients could get out of bed without strict bed rest.
Results 154 cases successfully did CAG through radial artery way in 162 patients, and the successful rate was 95.06%. The results show: 33 patients were normal (20.37%) and 129 patients had lesions (79.3%). Single vessel lesions was 68 cases, double vessels lesions was 36 cases, and three vessels lesions was 25 cases.
Conclusions Through radial artery way to do CAG is the basic technology of coronary intervention. It has minimal trauma, fewer bleeding, fewer complications, and patients easily accepted, etc. It is worthy of generalisation in clinical application.
