Prophylactic antibiotics for percutaneous endovascular procedures.

Area of Science:

• Vascular Surgery
• Infectious Diseases
• Pharmacology

Background:

• Percutaneous endovascular techniques are increasingly common for vascular disease, offering advantages over open surgery.
• While endovascular procedures have lower infection rates than open surgery, infections that do occur are severe and can lead to limb loss or death.
• The evidence for prophylactic antibiotic use in endovascular procedures is less robust than for open surgery.

Purpose of the Study:

• To review the existing evidence on the use of prophylactic antibiotics in percutaneous endovascular procedures.
• To highlight the need for further research, including randomized controlled trials, to guide clinical practice.
• To discuss the balance between preventing infections and the potential downsides of antibiotic use.

Main Methods:

• Literature review of studies on prophylactic antibiotics in endovascular procedures.
• Analysis of guidelines from professional societies, such as the Society of Interventional Radiology.
• Discussion of the benefits versus risks, including cost, antimicrobial resistance, and patient side effects.

Main Results:

• Infectious complications from endovascular procedures, though less frequent, are devastating.
• The Society of Interventional Radiology issued guidelines in 2010 based on limited evidence.
• The number needed to treat to prevent one infection is high, but serious adverse outcomes can occur without prophylaxis.

Conclusions:

• There is a need for high-quality randomized controlled trials to establish definitive guidelines for antibiotic prophylaxis in endovascular procedures.
• Clinical decisions must weigh the benefits of infection prevention against the economic costs and risks of antimicrobial resistance.
• Further research is essential to optimize patient care and reduce the incidence of severe endovascular prosthesis infections.
