Abstract
A 78-year-old man was admitted to our hospital with a chief complaint of gross hematuria. The patient was diagnosed with pelvic arteriovenous malformations and repeated arterial embolization. A cystoscopy demonstrated that bladder trigone was covered by many clots. At the same time, bleeding mucosa at the right side of the bladder dome was confirmed. We administered hyperbaric oxygen therapy 7 days after admission. Macrohematuria recovered gradually and we then performed transurethral coagulation at the dome with failed mucosa 14 days after admission. Macrohematuria recovered completely and there was no recurrence during hospitalization. Thirty days after admission, we performed cystoscopy and found clear mucosa in the trigone. The patient was discharged 32 days after admission.
Highlights
Pelvic arteriovenous malformations (P-AVM) are rare, especially in males
When P-AVM are suspected, an angiogram and pelvic computed tomography (CT) or magnetic resonance imaging (MRI) are essential to delineate the extent of the disease
hyperbaric oxygen therapy (HBO) therapy is indicated for patients with hemorrhagic cystitis caused by radiation, intractable interstitial cystitis, or cyclophosphamide-induced hemorrhagic cystitis
Summary
Pelvic arteriovenous malformations (P-AVM) are rare, especially in males. Angiography is effective for the diagnosis, and for embolization therapy of AVM in the pelvis; we sometimes have to repeat embolization many times because of continuous symptoms or insufficient efficacies. We attempted hyperbaric oxygen therapy (HBO) and transurethral coagulation (TUC) for abnormal vessels and persistent macrohematuria from P-AVM and showed good efficacies
