ABSTRACT
A case of polyarteritis nodosa was reviewed. The patient was a 58-year-old middle-aged man. He developed fever, headache, fatigue and other symptoms. Three weeks after, massive hematuria was seen. CT plain scan and MRI indicated blood clots in renal pelvis, and pericardium and pleural effusion. Renal arteriography indicated multiple venous fistula in both kidneys. Enhanced CT scan showed multiple small aneurysms in abdominal aortic branches, bilateral renal arteries and pancreatic arteries. The diagnosis of nodular polyarteritis was confirmed. Glucocorticoid and immunosuppressive agents were given. Meanwhile, highly selective renal arteriovenous fistula embolization was performed, Postoperative hematuria was effectively controlled, and the general condition was gradually improved. The patient was followed up for 2 months, and the condition was stable.
