POSTOPERATIVE ULTRASOUND ASSESSMENT OF THE HEAD VEIN FLOW AND DIAMETER OF AUTOGENOUS ARTERIOVENOUS FISTULAS MEETS THE REQUIREMENTS FOR DIALYSIS

Objective: To study the rehabilitation nursing of cephalic vein radial artery fistula angioplasty in patients with renal failure. Methods: Patients with established autologous arteriovenous fistula were the research object. This study collected the following data from 324 patients with primary disease: age, preoperative vascular colour Doppler ultrasound, surgical site (wrist, middle forearm and high position near the elbow fossa), complications within 2 months after surgery (including internal fistula occlusion) and postoperative fistula dysfunction within 2 months. SPSS-19.0 statistical software was used for analysis. The relationships between the success rate of surgery, occurrence of postoperative clinical complications and aetiology, age, vascular condition, surgical site, method and postoperative patient treatment were analysed. Results: In this study, 19 cases (6.2%) of internal fistula dysfunction were evaluated 2 months after surgery. The incidences of swollen hand syndrome and heart failure near the elbow fossa and middle forearm were higher than those of a wrist fistula (P<0.05). Patients with an internal fistula and the simultaneous resection of an aneurysm had a high infection rate of the internal fistula (P<0.05). Intraoperative secondary surgical anastomosis was related to vascular conditions (P<0.05) and surgical methods. Conclusion: The results of this study show that postoperative ultrasound assessments of the head vein flow and diameter of autogenous arteriovenous fistulas meet the requirements for dialysis, which can help to detect the early use of an arteriovenous fistula to diagnose and treat it as soon as possible while striving for reuse.
