Day case angioplasty in a secondary care setting - initial experience

Abstract

Background: Peripheral artery disease presents an increasing healthcare burden worldwide. Day-case angioplasty in a secondary care setting can be a safe and effective means of meeting the growing demand for lower limb revascularisation. We evaluated the safety and efficacy of a day-case-based angioplasty service in a UK district general hospital. Patients and methods: Consecutive patients undergoing endovascular revascularisation between August 2018-February 2020 were analysed retrospectively. All patients were discussed at a multi-disciplinary (diabetic foot) team meeting following a day case algorithm. Patient and procedural characteristics, technical success, peri-procedural complications, and 30-day outcome of day-case angioplasties were compared with those requiring overnight stay or were hospitalized. Results: Fifty-seven percent of 138 patients were diabetic, mean age 75 ± 12 years, 95% had critical limb ischaemia (Fontaine III 12%, IV 83%), and baseline ankle brachial pressure index [ABPI] 0.40 ± 0.30. Sixty-three patients (45%) were treated as planned day cases, 21 (15%) required overnight admission for social indications. Fifteen (11%) were planned admissions with the need for sequential debridement procedures, and 39 (28%) were already hospitalised at the time of referral to the vascular service. The overall technical success was 92% and not successful procedures mainly occurred in patients > 80 years. The ABPI increased at the initial follow-up to 0.84 ± 0.18. Fifty-three percent required treatment of > 1 level, 80% included recanalisations of chronic total occlusions, and average total lesion length was 133 ± 90 mm. Closure devices were employed in all cases. There were no major peri-procedural complications. A single minor access-site related bleeding episode (0.8%) occurred, requiring 24 h observation in hospital. While significantly more wounds had closed in out-patients, the mortality, major amputation and target lesion revascularization did not differ between groups. Conclusions: Safe and effective day-case-based angioplasty can be provided in a secondary care setting for patients with critical limb ischaemia needing complex multi-level procedures.
