The pulse of the dorsal artery of the foot disappears

Introduction Lower extremity atherosclerosis is often accompanied by numbness of the extremities, and the pulsation of the dorsal artery of the foot disappears.

Cause

Lower extremity atherosclerotic occlusive disease is a common chronic arterial occlusive disease, which may be related to cholesterol metabolism disorder, hypertension and arterial wall dysfunction. The lesions occur mostly in the abdominal aortic bifurcation and lower limbs. artery. Due to atherosclerosis, fibrosis and calcification, the intima of the arteries cause stenosis or occlusion of the lumen, which is mostly segmental.

Cardiovascular angiography and arterial wall status

The disease is more common in middle-aged and elderly people, often accompanied by a history of hypertension. The early symptoms are mainly intermittent claudication, and the pain at rest is the manifestation of severe ischemia of the lower extremities, often accompanied by numbness of the extremities. Acromegaly ulcers and gangrene can also occur in the advanced stage. Physical examination revealed a decrease in extremity skin temperature, a stenosis, or a weakening or disappearance of the distal arterial pulsation of the occlusion artery. Doppler ultrasound and angiography can be used to determine the location, extent and extent of the disease and contribute to the choice of surgical approach.

Differential diagnosis

In patients with coronary atherosclerosis, angina pectoris, myocardial infarction, arrhythmia, and even sudden death may occur if the diameter of the vessel is narrowed by more than 75%.

Cerebral arteriosclerosis can cause cerebral ischemia (including transient ischemic attacks), brain atrophy, or cerebral vascular rupture. Early stage of cerebral arteriosclerosis: neurasthenia (often dizziness, dizziness, headache, tinnitus, lethargy, memory loss, fatigue), emotional abnormalities (emotional irritability, lack of self-control, as the condition worsens, will gradually change Indifferent expression, lack of interest in the surrounding things), low judgment ability (expressed as unable to concentrate attention, imagination reduced, to deal with problems rely on others to assist). When cerebral arteriosclerosis reaches the middle and late stages, gait stiffness or walking instability, dementia, epileptic seizures, and stroke may occur.

Renal atherosclerosis often causes nocturia, refractory hypertension, and severe renal insufficiency.

Mesenteric atherosclerosis can be manifested as symptoms such as abdominal pain and blood in the stool after a meal.
