S35.403

Clinical Causes: Blunt trauma to the abdomen or flank, often from motor vehicle accidents, falls, or sports injuries. Penetrating injuries such as stab wounds or gunshot wounds. Surgical complications involving the kidney or nearby structures. Aortic aneurysm or dissection that compromises the renal artery. Sudden, severe physical impact that causes tearing or stretching of the artery.

Key Symptoms: Flank pain or abdominal pain, often sudden and severe. Hematoma or bruising near the injury site. Blood in the urine (hematuria). Signs of decreased kidney function, such as swelling or fluid retention. Possible hypotension or signs of shock if bleeding is significant. Symptoms of general trauma, depending on other injuries sustained.

Diagnosis Path: To confirm an injury to the renal artery, healthcare providers may perform a variety of diagnostic tests, including: - Physical examination focusing on pain and tenderness. - Imaging studies such as CT scan with contrast to visualize blood vessels. - Doppler ultrasound to assess blood flow to the kidneys. - Angiography if detailed vascular imaging is needed. These tests help determine the location, severity, and implications of the injury, guiding further treatment decisions.

Treatment Protocols: Management of an unspecified renal artery injury depends on the severity of the damage and the patient's overall condition. Common approaches include: - Monitoring and supportive care for minor injuries. - Blood pressure control to minimize additional damage. - Endovascular procedures such as stent placement or embolization to repair the artery. - Surgical repair in cases of significant bleeding, artery transection, or other complex injuries. - Blood transfusions if due to bleeding. - Treatment of associated injuries or complications. Follow-up care involves monitoring renal function and ensuring proper healing to prevent long-term complications.
