Hemorrhage From Ruptured Utero-Ovarian Veins During Pregnancy

Abstract

Because of difficulty in reinducing comparable degrees of hypoprothrombinemia in the same patient with identical doses of this anticoagulant, it is difficult to determine the effectiveness of the antagonists. Use of menadione sodium bisulfite seems to accelerate slightly the return to normal, particularly if the prothrombin time is prolonged beyond the upper limit of the therapeutic range. It is questionable whether vitamin Kt given orally is more effective, but if given intravenously it may be slightly more effective as an antagonist for ethyl biscoumacetate.Experiments on animals have indicated that when extreme degrees of hypoprothrombinemia were induced and maintained with anticoagulant No. 63, less bleeding was encountered than when similar degrees of hypoprothrombinemia were induced and maintained with bishydroxycoumarin. With adequately controlled anticoagulant therapy comparable situations should not be

Concealed post-partum haemorrhageaemor: A case report

“…The tortuous path and lack of valves of these vessels, combined with significant distension from elevated venous pressure in pregnancy and labour may predispose them to rupture. A possible individual underlying vascular defect may increase the risk [2].…”

“…Approximately 120 cases have been reported in literature, the majority (61%) directly related to labour [1]. Maternal mortality rate has decreased significantly from 49% in 1950 [2] to 4% in 1987, mainly due to improvement in anesthetic and bloodbanking techniques. Perinatal mortality remains high at 31% [1].…”

Decidual Bleeding as a Cause of Spontaneous Hemoperitoneum in Pregnancy and Risk of Preterm Birth

“…Although the aetiology of SHiP remains unknown and may be multifactorial, several theories have been proposed to explain the rare complication ( Table 1 ). The early reports describing this complication suggested venous rupture due to a sudden increase in venous pressure associated with muscular activity, defecation, coughing, lifting or coitus [3] . Increased pelvic congestion and blood flow, the tortuous path of the uterine and ovarian veins, their lack of valves and their distension with elevated intraluminal pressure may provide vascular conditions for the dramatic event [4] .…”

Spontaneous Rupture of Uterine Varicose Vein at 38 Weeks of Pregnancy: A Rare Case Report

“…This is a very rare, life threatening complication of pregnancy and puerperium. 3 As the veins rupture blood generally collects intraperitoneally, when the ruptured vein is situated on the uterus; or may collect retroperitoneally, when situated within broad ligament, as loose tissue is present within two leaves of broad ligament. Massive amount of blood may collect intraperitoneally (hemoperitoneum) so that patient presents with acute pain abdomen, shock and collapse, mimicking uterine rupture or placental abruption.…”

“…Both maternal and fetal mortality is high, maternal 49%. 3 But the mortality is reduced to 4.7% due to improved surgical and anesthetic equipments. This type of venous rupture generally occurs before onset of labour (61%), but rupture may be intrapartum (18%) or in puerperium (21%).…”
