Uterine vaginal artery

The uterine artery arises from the anterior division of the internal iliac artery usually close to, or in common with the middle hemorrhoidal or vaginal artery. There are several configurations for the origin of the uterine artery. It can be the first... 

Anatomic Considerations The bladder is supplied by the superior and inferior vesical arteries derived from the anterior trunk of the internal iliac artery. With anatomic variation, the vesical arteries may originate from the obturator and inferior gluteal arteries, and in the female, additional branches are derived from the uterine and vaginal arteries. When... 

Technical Considerations The placement of the catheters in both internal iliac arteries, selectively into the main trunks, the anterior divisions, the vaginal arteries from the pudendals or the uterine arteries depends on the blood supply to the tumors and the flow distribution as evaluated by angiography, radionuclide flow study, and CT angiography.

The human vagina, a fibromuscular tube 10-15 cm long, extends upwards and backwards from the vulva to the lower uterine cervix. Blood is supplied to the vagina via the uterine and pudendal arteries, and is drained from the vagina by a rich plexus, which flows into the internal iliac veins. The surface of the vaginal epithelium is kept moist by cervical secretions. The pH of vaginal fluid is 4-5. 

There have been complications reported in association with the use of trisacryl gelatin microspheres. De Blok et al. reported a case of fatal sepsis after uterine artery embolization performed with this agent. In this case, diffuse necrosis of the vaginal wall and cervix was found, attributed to distal penetration of spheres measuring 500-700 p in diameter...

A reported complication after uterine artery embolization has been a persistent vaginal discharge [86]. This discharge, which is often characterized as brown or red-brown in color, can begin within days of the embolization procedure and can potentially last for several months [7]. Vaginal discharge may be more frequent in patients with submucosal fibroids or when embolization of the uterine arteries to stasis has been performed (Fig. 10.4.8) [7,53]. 

Uterine artery embolization (UAE) is an established technique that has been used to stop life-threatening vaginal hemorrhage in women with malignancy, postpartum uterine atony, or traumatic injury since the mid-1970s [8,18,52,64,112]. The first successful treatment of symptomatic fibroids of the uterus by UAE was reported by Ravina et al. in 1994 [150].
