Severe hypertension in a patient treated with retroperitoneal radiotherapy was linked to renal artery stenosis. Angioplasty successfully normalized blood pressure, highlighting the need to screen patients for renovascular hypertension after radiation therapy.

Area of Science:

  • Cardiovascular Medicine
  • Oncology
  • Radiology

Background:

  • Retroperitoneal radiotherapy for testicular cancer can lead to long-term vascular complications.
  • Severe refractory hypertension is a potential adverse effect of radiation-induced arterial injury.
  • Renovascular hypertension, caused by renal artery stenosis, is a treatable cause of hypertension.

Observation:

  • A 41-year-old musician presented with severe, treatment-resistant hypertension 13 years post-radiotherapy for retroperitoneal teratocarcinoma.
  • Angiography identified significant stenosis in both renal arteries.
  • Percutaneous transluminal angioplasty of the stenotic renal arteries was performed.

Findings:

  • Following angioplasty, the patient's blood pressure normalized, indicating successful treatment of renovascular hypertension.

  • Radiation-induced arterial injury can mimic common atherosclerosis but may lead to critical stenoses.
  • This case underscores the link between past retroperitoneal radiation and subsequent renovascular complications.

    • Implications:

    • Patients with a history of retroperitoneal radiotherapy require vigilant screening for renovascular hypertension.
    • Early detection and intervention, such as angioplasty, can effectively manage radiation-induced renovascular disease.
    • Understanding the long-term sequelae of radiotherapy is crucial for comprehensive patient care and management.
