Blood pressure and pulse asymmetry in extremities

Introduction Abnormal blood pressure pulse of the extremities: Sudden chest pain and painful electrocardiogram and myocardial enzymology without obvious abnormalities, limb blood pressure pulse asymmetry, aortic regurgitation murmur and aortic branch involvement caused by corresponding organs (brain , heart, kidney, etc.) ischemic and functional changes, is an important manifestation and diagnostic clue of aortic dissection.

Cause

The cause is still unknown. The blood penetrates into the middle layer of the aorta to form a dissected hematoma and extends along the aortic wall.

In case of the above performance, the aortic dissection may be highly suspected, and imaging examination should be performed in time. In recent years, various examination methods have greatly helped to establish aortic dissection. CT, B-ultrasound, and MRI can provide reliable evidence for aortic dissection diagnosis.

Differential diagnosis

To be differentiated from acral ischemia. Limb ischemia is a symptom caused by insufficient blood supply at the extremities of the extremities.

In case of the above performance, the aortic dissection may be highly suspected, and imaging examination should be performed in time.
