Revision Rate and Risk Factors After Lower Extremity Amputation in Diabetic or Dysvascular Patients
Lower extremity amputations in patients with diabetes or peripheral arterial disease (PAD) show a 25.2% revision rate. Diabetic nephropathy and polyneuropathy are key risk factors for revision, necessitating a multidisciplinary approach.
Area of Science:
- Vascular Surgery
- Diabetology
- Orthopedics
Background:
- Lower extremity amputations are common in patients with diabetes mellitus and peripheral arterial disease (PAD).
- Revision amputations are often necessary to address complications or optimize function.
- Understanding risk factors for revision is crucial for improving patient outcomes.
Purpose of the Study:
- To determine the revision rate of lower extremity amputations in patients with diabetes mellitus or PAD.
- To identify risk factors associated with amputation revision.
- To inform clinical practice regarding amputation level determination.
Main Methods:
- Retrospective analysis of 421 patients undergoing lower extremity amputation between 2002 and 2012.
- Data collection included patient demographics, comorbidities, amputation level, and revision status.
- Statistical analysis to identify risk factors for revision, including logistic regression.
Main Results:
- The overall revision rate was 25.2%, with a mean time to revision of 244 days.
- Patients with diabetes mellitus had a higher likelihood of revision to a more proximal level.
- Diabetic nephropathy and polyneuropathy were significant risk factors for revision (OR=2.26 and OR=1.68, respectively).
- Patients undergoing revision were significantly younger than those who did not.
Conclusions:
- A significant proportion of lower extremity amputations in patients with diabetes or PAD require revision.
- Identifying risk factors like diabetic nephropathy and polyneuropathy can guide preventative strategies.
- A multidisciplinary approach and individualized assessment of amputation level are essential for optimizing patient outcomes and mobilization potential.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
