    ARTERIES AND VEINS OF THE INTERNAL GENITALIA OF FEMALE SWINE S. L. OXENREIDER, R. C. McCLURE and B. N. DAY Missouri Agricultural Experiment Station, Departments of Animal Husbandry and School of Veterinary Medicine, Department of Veterinary Anatomy, Columbia, Missouri, U.S.A. {Received 22nd May 1964) Summary. The angioarchitecture of the internal genitalia of twenty-six female swine was studied. The arteries of the genitalia of female swine anastomose freely allowing fluid injected into one artery to flow into all other arteries of the genitalia. A similar degree of anastomosis exists in the veins. There is no branch to the uterine horn from the so-called utero- ovarian artery and a more descriptive name for the artery would be ovarian. Also, it is more appropriate to refer to the artery originating from the umbilical artery as the uterine instead of middle uterine artery since it supplies the entire uterine horn and there is no cranial uterine artery in the pig. The uterine branch of the urogenital artery supplies the cervix and uterine body. Two large veins are located bilaterally in the mesometrium of the uterus. The larger is nearer the uterine horn, runs the entire length of the horn and is a utero-ovarian vein. It follows the ovarian artery after receiving one or two venous branches from the ovary. An additional large vein which parallels the utero-ovarian vein in the mesometrium is designated as the uterine vein since it follows the uterine artery. The uterine vein anastomoses with the utero-ovarian vein through one large branch and many smaller branches and enters a ureteric vein as the uterine artery crosses the ureter.

However, patients with pelvic congestion syndrome can also present with haemorrhoids, vulvoperineal or posterior upper thigh varices, or previous varicose vein 3a 3b 4a 4b treatment failure. Endovascular treatment with pelvic and ovarian vein embolisation has been shown to be effective in providing significant symptomatic relief and has been gaining increased acceptance. There are challenges that can lead to difficulty in diagnosing the condition or treatment failure / partial response, especially the relatively low sensitivity of different imaging modalities, variant anatomy and associated anatomic disorders. Aims: 1. To demonstrate the anatomy of the interconnecting plexus of veins draining the pelvic organs and lower limb 2.

PVI is a hemodynamic phenomenon responsible for the occurrence of venous insufficiency of the lower extremities and recurrent varicose veins in nulliparous and parous women, as well as for a set of symptoms described as pelvic congestion syndrome (PCS). In the years 2017–2019, 535 patients admitted to our center with symptoms of venous insufficiency of the lower extremities, underwent complete ultrasound diagnostics (color-duplex ultrasound) of the venous system of the abdomen, pelvis and lower limbs, as well as extended imaging diagnostics using computed tomography (CT) or magnetic resonance (MR) venography. On the basis of the obtained results, the authors proposed a 4-grade hemodynamic and radiological classification (grades I-IV) defining the stratification of ovarian veins insufficiency. Using the above mentioned classification approx. 32% patients were identified as Grade I and I/II, approximately 35% revealed morphological and hemodynamic changes corresponding to Grade II and II/III, approximately 25% were classified Citation: Szary, C.; Wilczko, J.; as Grade III, whereas the remaining 8% were assessed as Grade IV.

  • Idiopathic Ovarian Vein Thrombosis: a Rare Cause of Abdominal Pain
    Open Access Case Report DOI: 10.7759/cureus.16756 Idiopathic Ovarian Vein Thrombosis: A Rare Cause of Abdominal Pain Nayha Tahir 1 , Robin Sherchan 1 , Aneeba Farooqi 1 , Jishna Shrestha 1 , Hafiz Muhammad Jeelani 1 1. Internal Medicine, Northwestern Medicine McHenry Hospital, Rosalind Franklin University of Medicine and Science, McHenry, USA Corresponding author: Nayha Tahir, [email protected] Abstract Ovarian vein thrombosis (OVT) is a rare entity. It is usually seen in hypercoagulable states such as pregnancy, peripartum period, active malignancy, recent pelvic surgeries, pelvic infections, and inherited or acquired thrombophilias. Idiopathic OVT is exceedingly rare. We report a case of OVT in a healthy 42-year- old post-menopausal female presenting with right lower quadrant abdominal pain for four days. The patient denied any recent pelvic surgery, pelvic infection, or any family history of thrombophilia. Right ovarian vein thrombosis was found on a computed tomography scan of the abdomen and pelvis. Laboratory workup including hypercoagulability studies was normal. The patient was treated with a therapeutic dose of lower molecular weight heparin and later transitioned to rivaroxaban for three to six months. This case emphasizes OVT as a differential diagnosis of lower abdominal pain in healthy females. Currently, there are no standard guidelines for the duration of anticoagulation in OVT, however based on literature review, deep venous thrombosis treatment guidelines can be followed. Categories: Internal Medicine, Obstetrics/Gynecology, Hematology Keywords: idiopathic ovarian vein thrombosis, hypercoagulable state, septic pelvic thrombophlebitis, vitamin k antagonists, direct-acting oral anticoagulants Introduction Ovarian vein thrombosis (OVT) is commonly seen in hypercoagulable states. OVT in the postpartum period has been reported in approximately less than 0.19% of pregnancies [1].

MAKOWSKI** of Colorado Medical Center, GIACOMO MESCHIAt 4200Denver,EatColoradoNinth Avenue,80220 PHYSIOLOGIC STUDY OF THE UTERINE VENOUS DRAINAGE OF THE PREGNANT RHESUS MONKEY: The proportion of the total venous drainage from the uterus which repre- sents drainage of the placenta versus myometrial and endometrial drainage has not been defined in any primate. Furthermore, the extent to which this proportion varies in the principal veins draining the pregnant uterus is not known. This information is particularly important in the application of the Fick principle to the determination of uterine blood flows and placental function. In the past a steady diffusion technique involving a constant infusion of a rapidly diffusible solute into the fetal circulation has been applied to the sheep placenta to give measurements of uterine and umbilical blood flows.' In two recent publications, other investigators have applied to the rhesus monkey this method originally developed for the simultaneous measurement of the uterine and umbilical blood flows in sheep.2" Since the method is based upon the Fick principle, its application requires venous blood sam- ples which are representative of the venous drainage of the whole uterus or, alternatively, sufficient information to estimate the composition of the representative venous samples. We shall demonstrate in this paper that in the pregnant rhesus monkey, venous drainage by the two ovarian veins is often unequal in composition and variable. In the light of this finding, we shall examine the uterine flow data that have been published and indicate the systematic errors involved in the calculation of these data.

  • Postpartum Ovarian Vein Thrombosis: Clinical Case
    Case Report Journal of Clinical Obstetrics, Gynecology & Infertility Published: 18 Nov, 2019 Postpartum Ovarian Vein Thrombosis: Clinical Case Ana Ribeiro1*, Rafael Brás2, Maria Lúcia Moleiro2, António Braga2 and Jorge Braga2 1Department of Obstetrics and Gynecology, Centro Hospitalar do Baixo Vouga, Portugal 2Department of Obstetrics and Gynecology, Centro Materno Infantil do Norte, Portugal Abstract Ovarian Vein Thrombosis (OVT) is a rare but potentially serious postpartum complication, which occurs in 0.05% to 0.18% of pregnancies and is diagnosed on the right side in 80% to 90% of the cases. As OVT can mimic acute abdomen it should be considered in the differential diagnosis of postpartum acute abdomen. We present a case of a 29-year-old female who presented a diffuse abdominal pain, fever and vomit on her third postpartum day. Her computed tomography demonstrated left ovarian vein repletion defect compatible with the presence of a thrombus. She was treated with enoxaparin and antibiotics, which lead to a resolution of the thrombus. Our case highlights the importance of prompt diagnosis and treatment of OVT in order to prevent morbidity and mortality. Keywords: Ovarian vein thrombosis; Thrombosis; Anticoagulation; Postpartum Abbreviations OVT: Ovarian Vein Thrombosis; CT: Computed Tomography Introduction Ovarian vein thrombosis is a rare but potentially serious condition that affects mostly postpartum women but it may also be associated with a variety of pelvic conditions, such as pelvic inflammatory disease, gynecological surgery, and malignancies [1]. Early recognition and treatment of this condition is needed to avoid the morbidity and the mortality related both to the thrombosis and to any associated infection or sepsis.
