Compared with traditional trans-radial artery access (TRA), there are limited data that can confirm the efficacy and safety of a 7F thin-walled sheath placed
This study aims to analyze the safety and efficacy of the placement of a 7F thin-walled sheath
This was a single-center retrospective observational study in which 102 patients who received complex PCIs with a 7F thin-walled sheath placed
The puncture success rate was 90.2% in the 102 patients, and the success rate of the operation was 97.8% among 92 patients with a successful puncture. The PCIs for patients included emergency PCIs and all types of complex PCIs. Color Doppler ultrasound performed at 1 and 30 d after the procedure showed that the RAO rate was 2.2%, the distal RAO rate was 3.3%, the postoperative average pain score was 2.2 points, and there were five patients (5.4%) with local hematoma, all of which were grade 1–2. Radial artery spasm and nervous injury occurred in two patients (2.2%), and arteriovenous fistula occurred in one patient (1.1%). Radial artery perforation, radial artery dissection, pseudoaneurysm, and sheath kinking did not occur.
