Disease Case Studies
Peripheral Vascular Disease Case Studies
A 52-year-old man complained of pain and cramping in his right calf caused by walking two blocks. The pain was relieved with cessation of activity. The pain had been increasing in frequency and intensity. Physical examination findings were essentially normal except fordecreased hair on the right leg. The patient’s popliteal, dorsalis pedis, and posterior tibialpulses were markedly decreased compared with those of his left leg.
Studies
Results
Routine laboratory work
Within normal limits (WNL)
Doppler ultrasound systolic pressures
Femoral: 130 mm Hg; popliteal: 90 mm Hg; posterior tibial: 88 mm Hg; dorsalis pedis: 88 mm Hg (normal: same as brachial systolic blood pressure)
Arterial plethysmography
Decreased amplitude of distal femoral, popliteal, dorsalis pedis, and posterior tibial pulse waves
Femoral arteriography of right leg
Obstruction of the femoral artery at the midthigh level
