I77.73
Dissection of renal artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Dissection of the renal artery is a serious condition involving a tear in the wall of one of the arteries supplying blood to the kidneys. This tear causes blood to flow between the layers of the artery wall, which can lead to narrowing or blockage of the artery, affecting kidney function and blood pressure regulation.
Causes & Symptoms
Clinical Causes: Trauma or injury to the abdomen or back Underlying vascular conditions such as connective tissue disorders (e.g., Marfan syndrome, Ehlers-Danlos syndrome) Atherosclerosis or hardening of the arteries High blood pressure (hypertension) Degenerative changes in blood vessel walls Spontaneous dissection, sometimes without a clear cause Invasive medical procedures involving blood vessels
Key Symptoms: Sudden onset of severe flank or abdominal pain Pain radiating to the back or groin Blood in the urine (hematuria) Drop in blood pressure (hypotension), which may indicate bleeding Nausea and vomiting Signs of kidney dysfunction such as decreased urine output Possible swelling or tenderness in the abdomen
Diagnostic & Treatment
Diagnosis Path: Doppler ultrasound of the renal arteries to evaluate blood flow Computed tomography (CT) angiography for detailed images of blood vessels Magnetic resonance angiography (MRA) to assess vascular structures without radiation exposure Digital subtraction angiography, which allows direct visualization and potential treatment of the affected artery
Treatment Protocols: Blood pressure control to reduce stress on damaged arteries Medications such as pain relievers and anticoagulants to prevent clot formation Endovascular procedures like stent placement to support the artery wall and restore blood flow Surgical intervention in cases of extensive damage or ongoing bleeding Close monitoring and follow-up imaging to assess healing or progression
