  • Title: Bacterial-Infection-Associated Polyarteritis Nodosa Presenting as Acute, Rapidly Progressive Multiple Hepatic Artery Aneurysms.
    Author: Li L, Lao YH.
    Journal: Vasc Endovascular Surg; 2021 Apr; 55(3):295-299. PubMed ID: 33084540.
    Abstract:
    A 26-year-old male soldier was clinically characterized by transient fever, persistent right upper quadrant pain, hypertension, and elevated inflammatory biomarkers associated with bacterial infection. On the fifteenth day after the onset of symptoms, he had typical CT findings in polyarteritis nodosa involving only the hepatic arteries. Transcatheter arterial coil embolization of the right hepatic artery was performed due to ruptured hepatic aneurysms. Combination therapy with antibiotics and antihypertensives was administrated after embolization. The intrahepatic aneurysms completely vanished and inflammatory biomarkers returned to normal on the tenth day after embolization. The current case highlights the diagnosis and treatment of bacterial-infection-associated polyarteritis nodosa involving only the hepatic arteries, coexisting with hypertension.
