What are the symptoms of aortic dissection?

Explanation:
The key concept is recognizing the classic presentation of an aortic dissection. A dissection starts with a sudden, severe, tearing or ripping pain that often begins in the chest and can radiate to the back or abdomen as the false lumen extends. If the dissection involves branches of the aorta, you may see signs such as a pulse deficit or different blood pressures between limbs; hypotension can occur if the dissection ruptures into the mediastinum or pericardial space. The described scenario—severe stabbing pain from the back to the middle of the abdomen, along with possible hypotension and an absent left radial pulse when the subclavian artery is involved—fits these features precisely. It points to the involvement of arterial branches and potential hemodynamic compromise, which is characteristic of aortic dissection. Other presentations don’t align as well. Fever with severe arm numbness suggests infection or inflammatory processes or stroke rather than a dissection. Shortness of breath with clear lungs points more to pulmonary causes, such as PE or pneumothorax. Gradual chest pain relieved by antacids is more typical of acid-related or esophageal conditions rather than a dissection, which tends to be abrupt and severe. As a clinical note, a dissection is a medical emergency requiring prompt imaging (often CT angiography) and aggressive blood pressure and heart rate control to reduce shear stress on the aorta, followed by specialist management.
