I71.019
Dissection of thoracic aorta, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
Dissection of the thoracic aorta is a serious medical condition where there is a tear in the inner layer of the aorta, the main blood vessel that carries blood from the heart to the rest of the body. When this tear occurs in the thoracic part of the aorta — the section that runs through the chest — it can lead to severe complications and requires prompt medical attention. The specific ICD-10 code I71.019 refers to an unspecified dissection of the thoracic aorta, meaning the exact part of the thoracic aorta affected is not specified.
Causes & Symptoms
Clinical Causes: High blood pressure (hypertension) that weakens the aortic wall Atherosclerosis, which leads to plaque buildup and vessel weakening Genetic conditions like Marfan syndrome or Ehlers-Danlos syndrome affecting connective tissue Trauma or injury to the chest, such as a car accident or fall Previous aortic aneurysm or other vascular conditions Bicuspid aortic valve or other congenital heart defects
Key Symptoms: Sudden, severe chest or upper back pain, often described as tearing or ripping Pain radiating to the neck, jaw, or down the back Feeling of impending doom or severe anxiety Shortness of breath or difficulty breathing Weakness or paralysis in one or more limbs Loss of consciousness in severe cases Unequal pulse or blood pressure readings between limbs
Diagnostic & Treatment
Diagnosis Path: Computed tomography (CT) scan, especially CT angiography, which provides detailed images of the aorta Magnetic resonance imaging (MRI) or MR angiography to visualize blood flow and vessel structure Transesophageal echocardiography (TEE), an ultrasound probe inserted into the esophagus for close views of the thoracic aorta Chest X-ray, which might show a widened mediastinum or other indirect signs
Treatment Protocols: Immediate hospitalization for close monitoring Blood pressure control using intravenous medications to reduce stress on the aorta Surgical repair, which may involve replacing the damaged segment of the aorta with a synthetic graft, especially in cases of type A dissections involving the ascending aorta Endovascular procedures, such as stent graft placement, for suitable cases of descending aortic dissection Long-term management includes antihypertensive medications and lifestyle modifications to reduce the risk of recurrence
