I77.79
Dissection of other specified artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Dissection of other specified arteries, classified under ICD-10 code I77.79, is a condition where a tear develops in the wall of an artery, causing blood to flow between the layers of the artery wall. This leads to a separation, or dissection, which can impede blood flow and cause potential complications. While common arteries such as the carotid and aorta are frequently involved in dissections, this code applies to less typically affected arteries, making it a crucial diagnosis for specific vascular injuries or conditions.
Causes & Symptoms
Clinical Causes: Trauma or injury to the artery, such as from accidents or violent impacts Connective tissue disorders like Ehlers-Danlos syndrome or Marfan syndrome High blood pressure (hypertension) that exerts excessive stress on arterial walls Atherosclerosis, which damages artery walls over time Previous arterial surgeries or invasive procedures Certain infections affecting blood vessels Degeneration of blood vessel walls due to aging
Key Symptoms: Sudden and severe pain related to the affected area, which might be described as tearing or ripping Localized swelling or a visible lump over the affected artery Weakness, numbness, or tingling in the limbs or areas supplied by the artery Dizziness or fainting if blood flow to vital organs is compromised Changes in skin color, such as pallor or redness Signs of stroke or transient ischemic attack (TIA), including difficulty speaking, facial drooping, or weakness
Diagnostic & Treatment
Diagnosis Path: Diagnosing an arterial dissection involves a combination of clinical evaluation and imaging tests. Healthcare providers may use:
Treatment Protocols: Treatment approaches aim to prevent the progression of the dissection, restore normal blood flow, and minimize the risk of complications. Management can involve:
