- timeFrame
- Intraoperative and postoperative 30 days
- description
- Intraoperative adverse events (device and/or procedure-related). Events were recorded as Preferred Term and classified under System Organ Class as per MedDRA Common Terminology Criteria for Adverse Events (CTCAE) coding guidelines (https://evs.nci.nih.gov/ftp1/CTCAE/About.html). Postoperative complications will refer to any medical occurrence directly attributed to the surgical procedure within the first 30 days.
