Prolonged Procedural Time and Its Association With Periprocedural Complications in Endovascular Therapy

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Public Health

Background:

• Prolonged operative times in surgery correlate with higher complication risks.
• This association has not been systematically studied for endovascular therapy (EVT).
• Understanding this link is crucial for patient safety in EVT procedures.

Purpose of the Study:

• To determine the association between prolonged procedural time and periprocedural complications.
• Focus on patients undergoing EVT for symptomatic lower extremity arterial disease (LEAD).
• Quantify the risk increase associated with longer EVT durations.

Main Methods:

• Analysis of data from the Japan EVT registry (J-EVT) (2021-2022).
• Procedural time categorized into four groups: ≤59, 60-119, 120-179, and ≥180 minutes.
• Logistic regression used to assess periprocedural complication risk relative to the shortest time group.

Main Results:

• Analyzed 47,301 patients undergoing EVT for symptomatic LEAD.
• Periprocedural complications occurred in 0.9% of patients.
• Adjusted odds ratios for complications increased significantly with longer procedural times (≥120 min).

Conclusions:

• Prolonged procedural time in EVT for symptomatic LEAD is a significant risk factor.
• Longer procedures are independently associated with a higher likelihood of periprocedural complications.
• Emphasizes the importance of procedural efficiency in EVT for LEAD.
