Implementation of Endovenous Laser Ablation for Varicose Veins in a Large Community Hospital: The First 400 Procedures

Endovenous Laser ablation (ELA) has become a standard treatment of the incompetent great saphenous vein (GSV). Our prospective audit examines the implementation of this new method in a large community hospital with special attention to obstacles, technical results, pain scores, failures and our learning curve. Methods: Three hundred and twenty-three patients (403 limbs) with incompetence of the GSV underwent ELA. Patients were assessed by clinical examination and venous duplex ultrasound was performed 6 weeks after operation. Visual analog scale (VAS) pain scores of the first postoperative week were recorded. Operative time and success rate were analysed. Results: After 6 weeks, 301 (74.7%) treated legs were examined by duplex ultrasound imaging. Successful complete occlusion was present in 282 (93.7%) GSVs. Partial occlusion was present in 12 (4.0%) GSVs. In seven (2.3%) limbs the GSV was not occluded. The maximum mean VAS pain score was noted on the 5th postoperative day. From the start of this series, the operation time decreased rapidly for each surgeon, stabilising after 15 Limbs. Conclusion: ELA of the incompetent GSV is effective and safe. ELA is simple to perform, well accepted by patients and relatively atraumatic. In our opinion, ELA can be easily implemented in surgical practice. (C) 2008 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved

Association of Hospital Volume with Perioperative Mortality of Endovascular Repair of Complex Aortic Aneurysms: A Nationwide Cohort Study

Objective: We evaluate nationwide perioperative outcomes of complex EVAR and assess the volume-outcome association of complex EVAR. Summary of Background Data: Endovascular treatment with fenestrated (FEVAR) or branched (BEVAR) endografts is progressively used for excluding complex aortic aneurysms (complex AAs). It is unclear if a volumeoutcome association exists in endovascular treatment of complex AAs (complex EVAR). Methods: All patients prospectively registered in the Dutch Surgical Aneurysm Audit who underwent complex EVAR (FEVAR or BEVAR) between January 2016 and January 2020 were included. The effect of annual hospital volume on perioperative mortality was examined using multivariable logistic regression analyses. Patients were stratified into quartiles based on annual hospital volume to determine hospital volume categories. Results: We included 694 patients (539 FEVAR patients, 155 BEVAR patients). Perioperative mortality following FEVAR was 4.5% and 5.2% following BEVAR. Postoperative complication rates were 30.1% and 48.7%, respectively. The first quartile hospitals performed <9 procedures/ yr; second, third, and fourth quartile hospitals performed 9-12, 13-22, and 23 procedures/yr. The highest volume hospitals treated significantly more complex patients. Perioperative mortality of complex EVAR was 9.1% in hospitals with a volume of <9, and 2.5% in hospitals with a volume of 13 (P = 0.008). After adjustment for confounders, an annual volume of 13 was associated with less perioperative mortality compared to hospitals with a volume of <9. Conclusions: Data from this nationwide mandatory quality registry shows a significant effect of hospital volume on perioperative mortality following complex EVAR, with high volume complex EVAR centers demonstrating lower mortality rates
