The relationship between non-vascular access complications after cerebral vascular stent implantation and the COMPASS-31：

Background To investigate the relationship between non-vascular access complications after cerebral vascular stent implantation and the COMPASS-31. Methods A total of 545 patients who underwent cerebral vascular stent implantation in the A wards of neurology department between 30 November 2021 and 28 February 2024; 211 met the inclusion criteria. Patients were divided into the complication group and the no complication group according to whether they had complications of non-vascular access. The study compared the clinical characteristics and the COMPASS-31 score between the two groups. Results 118 patients (55.92%) experienced non-vascular access complications, including 35 cases of pain, 12 cases of dizziness, 19 cases of allergy, 47 cases of sleep disorders, 47 cases of gastrointestinal discomfort, 6 cases of cardiac discomfort, 25 cases of respiratory system lesions, and 6 cases of urinary system lesions. In contrast, 93 patients (44.08%) had not complications of non-vascular access. Among the patients with a COMPASS-31 score ≥ 18, 85 (55 cases, 64.71%) experienced non-vascular access complications. For those with a COMPASS-31 score < 18, 126 (63 cases, 50%) experienced non-vascular access complications. Sub-item analysis revealed that postoperative pain, dizziness, allergy and urinary system lesions were associated with the scores for gastrointestinal function, orthostatic intolerance, vasomotor function and bladder function in the COMPASS-31. Binary logistic regression analysis indicated that patients aged ≥ 45, with a COMPASS-31 score ≥ 18, had an Exp(B) value of 2.015 for non-vascular access complications after cerebral vascular stent implantation. Conclusion There was a significant correlation between postoperative non-vascular access complications and autonomic dysfunction.
