Successful management of uterine arteriovenous malformation by ligation of feeding artery after unsuccessful uterine artery embolization

JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2009

Abstract Uterine arteriovenous malformation (AVM) is a rare and potentially life-threatening disease. The present report describes a postmenopausal patient with uterine AVM manifesting recurrent, massive genital bleeding. Uterine artery embolization (UAE) was scheduled before hysterectomy, but UAE was unsuccessful due to the dilated, tortuous internal iliac arteries, and extremely rapid arterial blood flow. Hysterectomy appeared to carry a potential risk of massive blood loss due to multiple dilated vessels around the uterine corpus and cervix. Therefore, six arteries feeding the uterus were surgically ligated. At 10 months after the operation there have been no episodes of atypical genital bleeding. [source]

Macroscopic Features of the Arterial Supply to the Reproductive System of the Male Ostrich (Struthio camelus)

ANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 4 2007

Summary The macroscopic features of the arterial supply to the reproductive system of the male ostrich was studied in 16 pre-pubertal and eight sexually mature and active birds. The left and right cranial renal arteries arise from the aorta, between the cranial divisions of the kidneys. These vessels supply the cranial divisions of the kidneys, the testes, the epididymides and the cranial segments of the ducti deferentia. Accessory testicular arteries which arise directly from the aorta are present in 45.8% of the specimens. They supply the testes and cranial parts of the ducti deferentia. They are variable in number and origin, and four variants are identified. A cranial ureterodeferential branch originates from the cranial renal artery, supplies the cranial portion of the ductus deferens and ureter, and runs caudally to anastomose with the middle renal artery. The sciatic artery arises laterally from the aorta, just caudal to the acetabulum, and gives rise, ventrally, to a common trunk, the common renal artery, which divides into the middle and caudal renal arteries. The middle renal artery gives rise to the middle ureterodeferential branch which supplies the middle part of the ductus deferens and ureter. A few centimetres caudal to the kidney, the aorta terminates in three branches, namely, the left and right internal iliac arteries and the median caudal artery. The internal iliac artery divides into the lateral caudal artery and the pudendal artery; the latter gives off caudal ureterodeferential branches that supply the caudal segments of the ductus deferens and ureter. In addition, the pudendal artery gives off vessels that supply the cloaca, some of which continue to the base of the phallus, where they form an arterial network. In conclusion, the pattern of the blood supply to the reproductive organs of the male ostrich is, in general, similar to that of the domestic fowl and pigeon, although there are a few highlighted distinctive features.

Percutaneous intervention for chronic total occlusion of the internal iliac artery for unrelenting buttock claudication,

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 2 2009

Abstract Internal iliac artery stenosis or occlusion has been documented to cause hip pain, erectile dysfunction, and buttock claudication. Endovascular repair for patients with significant stenosis has been well documented, but chronic total occlusion revascularizations have not been reported in the literature. The reluctance to attempt percutaneous intervention may be in part due to the extensive collateralization that forms to this vessel, or fear of complications such as wire perforation in a vessel that has a tortuous route with multiple bifurcations. This report describes two cases of patients with unrelenting buttock claudication that completely resolved after percutaneous intervention of unilateral chronic total occlusions of the internal iliac artery. © 2008 Wiley-Liss, Inc.

The iliolumbar artery,Anatomic considerations and details on the common iliac artery trifurcation

CLINICAL ANATOMY, Issue 1 2010
M.C. Rusu
Abstract The iliolumbar artery (ILA) of Haller is the largest nutrient pedicle of the ilium and its detailed knowledge is important for various surgical procedures that approach the lumbosacral junction, the L4/L5 disk space, the sacroiliac joint, the iliac and psoas muscles, or the lumbar spine. Also the ILA is relevant for various techniques of embolization. We aimed to evaluate the anatomic and topographic features of the ILA, by dissection on 30 human adult pelvic halves and on 50 angiograms. ILA was a constant presence and it emerged at Level A (from the common iliac artery (CIA), 8.75%), Level B (from the CIA bifurcation, 2.5%), Level C (from the internal iliac artery (IIA), 52.5%), Level D (from the IIA bifurcation, 3.75%), and Level E (from the posterior trunk of the IIA, 32.5%). Level B of origin of the ILA corresponds to a trifurcated CIA (morphology previously unreported), while Level D corresponds to a trifurcated IIA. A higher origin of the ILA corresponds to a more transversal course of it. A descending lumbar branch that leaves the iliac arterial system independently to enter the psoas major muscle, as seen in 48% of cases, may be misdiagnosed as ILA. Surgical interventions in the lumbar, sacral, and pelvic regions must take into account the variable origins of the ILA from the iliac system that can modify the expected topographical relations and may lead to undesired hemorrhagic accidents.
