Pseudoaneurysm as an unusual complication in bone lengthening

Area of Science:

• Vascular Surgery
• Orthopedic Surgery
• Medical Imaging

Background:

• Distraction osteogenesis techniques carry risks of vascular complications, including pseudoaneurysms.
• Pseudoaneurysms result from arterial wall injury and persistent blood leakage into surrounding tissues.

Observation:

• A rare case of a late-presenting pseudoaneurysm in the anterior tibial artery is described.
• The patient, a 57-year-old female with diabetic peripheral neuropathy, underwent tibial lengthening for leg length discrepancy.
• The pseudoaneurysm developed following the tibial lengthening procedure.

Findings:

• The diagnostic process for identifying the pseudoaneurysm is detailed.
• Treatment options for the pseudoaneurysm are discussed.
• The study confirms that the bony callus shape can serve as a reliable indicator of pseudoaneurysm development, consistent with prior literature.

Implications:

• This case underscores the importance of vigilance for vascular complications after distraction osteogenesis.
• Recognizing the significance of bony callus morphology can aid in early diagnosis of pseudoaneurysms.
• Improved diagnostic and treatment strategies for vascular complications in limb lengthening procedures are suggested.
