Reoperations for aortic surgery complications are reviewed. Metachronous aneurysms are the most common reason for reoperation, often asymptomatic and requiring routine screening after initial aortic surgery.

Area of Science:

  • Vascular Surgery
  • Cardiovascular Surgery
  • Surgical Outcomes

Background:

  • Long-term complications following conventional aortic surgery necessitate reoperative procedures.
  • Patients undergoing reoperative aortic surgery present unique challenges and outcomes.
  • Understanding trends in reoperative indications is crucial for patient management.

Purpose of the Study:

  • To review the presentation and management of long-term complications after aortic surgery.
  • To analyze outcomes of reoperative aortic procedures.
  • To identify the most common indications for reoperation and associated risk factors.

Main Methods:

  • A retrospective review of 97 consecutive patients undergoing 102 reoperative aortic procedures at a tertiary referral center.

  • Data collected included presenting symptoms, demographics, risk factors, indications for initial and reoperations, operative techniques, and outcomes.
  • Analysis of indications for reoperation, including subsequent aneurysms, graft occlusions, and infections.

    • Main Results:

    • Metachronous aneurysms were the most frequent indication for reoperation (65 cases), followed by graft occlusions (25) and infections (24).
    • One-third of subsequent aneurysms were asymptomatic and often undetected without routine screening.
    • Elective repair of aneurysms had a 5.1% mortality rate, while emergent repair of ruptured aneurysms had an 88% mortality rate. Graft infections requiring total removal had a 17% mortality rate.

    Conclusions:

    • Metachronous aneurysm formation is the leading indication for aortic reoperation, often presenting asymptomatically.
    • Routine computed tomographic (CT) examination every 5 years post-aortic surgery is advisable for early detection of aneurysms.
    • While elective reoperations can be performed safely, emergent procedures for ruptured aneurysms or complicated graft infections carry high mortality risks.
