Arteriovenous malformation of the urinary bladder: Treated by transurethral resection

Abstract

A localized arteriovenous malformation of the bladder is extremely rare. To our knowledge, arteriovenous malformation of the bladder has been reported in limited number of cases in the published literature. When arteriovenous malformation is suspected, an angiogram and pelvic computed tomography or magnetic resonance imaging is essential to delineate the extent of the disease and to plan appropriate therapy. Common symptoms include pain, gross hematuria and acute urinary retention.No well-established guidelines exist concerning their management. We report a case of an arteriovenous malformation of the urinary bladder that was successfully treated by transurethral resection.

Pelvic arteriovenous malformation (AVM) with recurrent hematuria: A case report

“…As a vascular abnormality, AVM is a snarled tangle of arteries and veins connected without capillaries, thereby disturbing organ perfusion. It has been shown that the global incidence and prevalence of AVMs are 1 and 10 cases per 100,000 individuals, respectively [ [7] , [8] , [9] ]. Moreover, these vascular lesions can be congenital or acquired.…”

A Unique Case: Arteriovenous Malformation of the Bladder Wall

“…The greatest danger is haemorrhage. Treatment for AVMs can include surgery or focused radiation therapy (1)(2)(3). We present a girl who had a mass with atypical localization arising from the bladder wall, diagnosed as arteriovenous malformation pathologically, due to very rare localization of AVM.…”

“…That interferes with the blood circulation in an organ. The cause is not known, but they seem to develop during pregnancy or soon after birth(1)(2)(3).AVMs most likely develop during the late somite stage in the fourth to eighth week of embryonic life. Early in the third week of embryonic life, angioblasts begin to differentiate from the mesoderm, forming syncytial islands.…”

“…These plexus contain afferent, efferent, and capillary portions. AVMs arise from persistent direct connection between the future arterial and venous sides of this primitive vascular plexus without the capillary component(1)(2)(3)(4).AVMs can be either congenital or acquired. AVMs can happen anywhere, but they are more common in the brain or spinal cord.…”
