However, these options are not suitable for all patients. We adopted patch angioplasty to reconstruct the hemodialysis access and observed this group of cases to evaluate the feasibility, effectiveness, and safety of this surgical method.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Between 2021 and 2024, we performed 14 cases of patch angioplasty using PTFE patch material.

During follow-up, 3 patients died respectively 2, 8, 9\u00a0months post-operation. The longest follow-up time was 38\u00a0months. The primary patency rates for target lesions were as follows: 92.3% at 3\u00a0months (12\/13), 81.8% at 6\u00a0months (9\/11), 77.8% at 12\u00a0months (7\/9), and 57.1% at 24\u00a0months (4\/7). The cumulative patency rates were: 3\u00a0months 100% (13\/13), 6\u00a0months 90.9% (10\/11), 12\u00a0months 88.9% (8\/9), and 24\u00a0months 71.4% (5\/7).
