Congenital Pelvic Arteriovenous Malformation Presenting with Urinary Retention: A Case Report

Abstract

Objective: To report a case of congenital pelvic arteriovenous malformation (pAVM) with urinary retention. Clinical Presentation and Intervention: A 39-year-old male patient presented with inability to void urine for 8 h. He did not have a history of dysuria or fever, but had increasing urinary frequency and difficulty in voiding over 2 years. Examination revealed a suprapubic mass without external signs of vascular anomaly. A huge, soft, irregular, non-pulsating mass was felt rectally. This mass did not disappear on urinary bladder decompression. Subsequent ultrasound and CT scan revealed pAVMs filling most of the pelvic cavity. Conclusion: To our knowledge, this is the first report of a male patient with congenital pAVM presenting with urinary retention, emphasizing the need for a high index of suspicion for pAVM to avoid potential severe bleeding during suprapubic catheterization for urinary drainage.

Localized prostate cancer with pelvic arteriovenous malformation treated with low‐dose‐rate brachytherapy after transcatheter embolization: Two case reports

“…pAVMs are uncommon vascular entities, which are classified as congenital or acquired which are secondary to trauma, operation, or pregnancy. 1,2 Both patients in this study reported no history of trauma or operation of pelvic organs; however, MRI performed before the prostate biopsy demonstrated AVMs. Thus, these lesions were classified as congenital pAVMs.…”

“…Thus, these lesions were classified as congenital pAVMs. pAVMs may present with pelvic pain, hematuria, dysuria, erectile dysfunction, heart failure, and massive bleeding during transurethral resection of the prostate . Both patients had been asymptomatic.…”

“…AVMs are abnormal connections between arteries and veins. AVMs are uncommon, and congenital pAVM particularly, are rare in men . To our knowledge, only one report has described definitive treatment (RP) for localized prostate cancer with pAVMs …”

“…AVMs are uncommon, and congenital pAVM particularly, are rare in men. 1,2 To our knowledge, only one report has described definitive treatment (RP) for localized prostate cancer with pAVMs. 3 LDR brachytherapy serves as definitive treatment for localized prostate cancer alongside RP and IMRT.…”

“…There are also cases described in literature in which AVMs are known to damage part of the sacrum and, by pressing on the nerve, cause sciatic neuralgia [5]. Hammad [6] describes a case of pAVM manifested by ischuria resulting from pressure on the bladder.…”
