Management of infected vascular prostheses

Area of Science:

• Vascular Surgery
• Infectious Diseases
• Wound Management

Background:

• Infected vascular prostheses pose significant risks, including suture line disruption and hemorrhage.
• Prompt and aggressive intervention is necessary for favorable patient outcomes.

Purpose of the Study:

• To outline an aggressive management strategy for infected vascular prostheses.
• To emphasize the importance of prevention in managing vascular graft infections.

Main Methods:

• Immediate aerobic and anaerobic cultures.
• Initiation of broad-spectrum antibiotics, adjusted based on sensitivities.
• Intensive local wound care for several days prior to prosthesis removal.
• Consideration of revascularization only if limb viability is compromised.

Main Results:

• Prolonged local therapy without graft removal is generally ill-advised.
• Hemorrhage necessitates immediate removal of the infected prosthesis segment.
• Revascularization, if needed, typically requires extra-anatomic bypass in uninfected tissue.

Conclusions:

• Early diagnosis and aggressive treatment, including potential graft excision, are vital.
• Prevention strategies, such as meticulous surgical technique and prophylactic antibiotics, are paramount.
• Delayed revascularization after infection clearance offers better long-term outcomes.
