Incidence of ipsilateral postoperative deep venous thrombosis in the amputated lower extremity of patients with peripheral obstructive arterial disease

Cumulative incidence of venous thrombosis of the amputation stump by the Kaplan-Meier method. The arrowhead indicates the average day of discharge after amputation.

Cumulative incidence by long-rank analysis of venous thrombosis of amputation stump divided by amputation level above knee (top line) and below knee (bottom line). The arrowhead indicates the average day of discharge after amputation.

Cumulative incidence by log-rank analysis of venous thrombosis of the amputation stump divided by age ≥70 years (top line) and age <70 (bottom line). The arrowhead indicates the average day of discharge after amputation.
