Patients suffered unnecessary harm, a loss of dignity, and substandard care as a result of failings in vascular services in one part of Wales.
A report by the Royal College of Surgeons (RCS) of England reviewed the case records of 44 patients who were under the care of vascular services at Betsi Cadwaladr University Health Board.
It found serious deficiencies in some patients' care as well as issues with record keeping, consent-taking, communication between clinicians, and documentation.
