Cervical varix as a cause of vaginal bleeding during pregnancy: prenatal diagnosis by color Doppler ultrasonography

Emergency postpartum hysterectomy as a consequence of cervical varix during pregnancy; a case report and literature review

INTRODUCTION AND IMPORTANCE

Vaginal bleeding might accrue during pregnancy and it has different causes due to the pregnancy trimester and the diagnosis and management would be crucial to prevent maternal-fetal life-threatening situations. In uncommon cases, varicose veins can emerge in the neck of the uterus, leading to a severe maternal hemorrhage.

CASE PRESENTATION

We presented a pregnant woman with vaginal bleeding and spotting during pregnancy with the diagnosis of cervical varix at 22 weeks of gestation. Close monitoring and proper patient education led to a term delivery at 37 weeks of gestation. Otherwise, an emergency postpartum hysterectomy after a cesarean section was performed due to uncontrolled bleeding from cervical varix.

CLINICAL DISCUSSION

Although rare, cervical varix should be included in the differential diagnosis in a pregnant patient who appears with extensive vaginal bleeding to reduce maternal and/or neonatal morbidity or fatality. The approved diagnosis for that is not clear.

CONCLUSION

This case report showed that Doppler and transvaginal sonography could be suitable diagnostic tools. The best management for cervical varix needs further research.

Four cases of cervical varices without placenta praevia: Presentation, diagnosis, managements, and literature review

Cervical varices are a rare condition characterized by recurrent antepartum hemorrhage and less than 20 cases were reported in the literature. It is usually associated with placenta previa. We herein describe four cases of cervical varices without placenta previa. Meticulous speculum examination, ultrasonography with Doppler and colposcopy are essential for establishing the diagnosis and assessing the extent of the cervical varix. We propose to classify it as the apparent external os type or ultrasonography-based endocervical type. Most cases presented in the literature were delivered by cesarean section. Nevertheless, one of our cases was a successful vaginal delivery. Our case illustrates that vaginal delivery is possible in isolated cervical varices. More case reports are needed to have a better understanding of this rare entity.

Effectiveness of Cross Double McDonald Cerclage for Intractable Bleeding from a Cervical Varix in Pregnant Women

Cervical varix during pregnancy is a rare condition, and standard management for bleeding from a varix has not been established. We performed cross double cervical cerclage and effectively stopped bleeding. A 41-year-old female had a twin pregnancy. The development of a cervical varix was observed during pregnancy and bleeding from ruptured varix started at 20 weeks of gestation. We performed surgical hemostasis by cervical cerclage. In the first cerclage, we could not stop the bleeding from the varix. For further restriction of blood supply to the cervical varix, we performed a second cerclage in a crossed position on a deeper side of the vagina than the first cerclage. Then the bleeding completely stopped and there was no bleeding until delivery. The "cross double McDonald cerclage" performed in our patient may be a useful modified cerclage method for stopping intractable bleeding from the cervix during pregnancy.

Pessary for Management of Cervical Varices Complicating Pregnancy

BACKGROUND

Cervical varices complicating pregnancy are rare but can cause significant maternal and perinatal morbidity. There is limited evidence regarding the optimal management of bleeding caused by cervical varices during pregnancy.

CASE

A 38-year-old woman was admitted to the hospital at 16 weeks of gestation due to vaginal hemorrhage in the setting of cervical varices accompanied by placenta previa. A cervical pessary was placed at 21 weeks of gestation without further bleeding. Magnetic resonance imaging demonstrated variceal reduction after pessary placement, and a cesarean delivery was performed at 36 weeks of gestation without complications.

CONCLUSION

Cervical pessary should be considered as conservative option to control the bleeding associated with cervical varices during pregnancy.

Bleeding cervical varices in pregnancy: A case report and review of the literature

BACKGROUND

Venous varicosities are a relatively common finding during pregnancy. Rarely, varices can arise in the cervix and cause life-threatening maternal hemorrhage. This article offers an example of a patient who was diagnosed with bleeding cervical varices during pregnancy and summarizes the diagnosis and treatment strategies for the 20 other reported cases in the literature.

METHODS

A PubMed literature search using the following terms was performed to gather data for the literature review: "bleeding" or "hemorrhage" and "cervical varices" or "cervical varix" or "cervical varicosities" and "pregnancy" or "obstetric" or "maternal." Individual references cited in each article were also evaluated for inclusion in this review.

RESULTS

A 50-year-old gravida 7 para 1 presented at 12 4/7 weeks with vaginal bleeding. Endo-vaginal ultrasound showed enhanced color Doppler signal in the endocervical canal. During a speculum exam, she was found to have active bleeding from ruptured cervical varicosities and required blood and fresh frozen plasma transfusion. Hemostasis was achieved with interrupted suture ligation. A McDonald cerclage was subsequently placed. She continued pregnant until delivery via cesarean section at 37 2/7 weeks. To date, there have only been 20 other reported cases of bleeding cervical varices during pregnancy.

CONCLUSIONS

This case report and review of the literature highlight the importance of including bleeding cervical varices in the differential diagnosis of maternal hemorrhage and offer a treatment strategy if cervical varicosities are discovered during pregnancy.

Cervical varices: An unusual source of first-trimester hemorrhage

Endocervical varices are a rare cause of obstetrical hemorrhage. Usually presenting in the second and third trimesters, bleeding varices often require pregnancy termination or indicated preterm birth via cesarean delivery. Our patient experienced variceal hemorrhage at 12 weeks' gestation in a dichorionic twin pregnancy conceived through in vitro fertilization. A low-lying placenta resolved at 19 weeks followed by variceal regression at 22 weeks' gestation. Endocervical varices causing first-trimester hemorrhage may regress with resolution of a coexisting low placental implantation, permitting planned vaginal delivery, despite progressive hemodynamic changes of pregnancy. © 2017 Wiley Periodicals, Inc.

Successful vaginal packing in placenta previa

Severe bleeding from placenta previa usually leads to immediate delivery. We report a case of a 23 weeks twin pregnancy who presented profuse bleeding while she was in the operating room for cervical cerclage. Cervical compression with a pack was applied in an attempt to gain time whilst preparing for cesarean section. The attempt was successful in halting bleeding and helped to extend the pregnancy until 33 weeks. We did not find a similar case in the literature and our conclusion was that in carefully selected cases, vaginal packing could be an immediate option to stop bleeding in placenta previa.

Cervical varicosities and placenta praevia

INTRODUCTION

Cervical varicosities (CVs) have been reported infrequently in pregnancy and have been associated with significant antepartum and postpartum haemorrhage. The most common association with CVs in pregnancy in the literature is placenta praevia.

AIMS

To further investigate the association between placenta praevia and CVs.

METHODS

A retrospective audit of all cases of placenta praevia that had an ultrasound in the Feto-Maternal Unit at Liverpool Hospital over the period January 2001 to January 2012. Patient outcomes were obtained from the hospital paper and electronic medical records, including mode of delivery and blood loss.

RESULTS

Eighty-four cases of placenta praevia were identified, and 78 had saved images that were reviewed. 51 of these 78 cases had transvaginal ultrasound (TVUS) images, which identified nine further cases of cervical varicosities. All cases of CVs were complicated by APH and delivered by caesarean section. There was no significant difference in the blood loss at delivery between the placenta praevia with CVs and those without (925 vs 870 mLs P = 0.3877).

CONCLUSIONS

Cervical varicosities are not as rare as the literature would suggest. The clinical relevance of the additional finding of CV on TVUS in cases of placenta praevia is questionable.

Pregnancy complicated by cervical varix and low-lying placenta: a case report

We present a case of cervical varix and low-lying placenta. A cesarean section was performed because of the risk of bleeding with vaginal delivery; hemostasis was achieved using z sutures at the bleeding points. After delivery, the cervical varix decreased dramatically in size. It is important to recognize the clinical features and available treatments for cervical varix.

Large volume cervical varix bleeding in a gravid patient

► Cervical varix during pregnancy is very rare and can coincide with massive bleeding. ► A gravid patient with a history of granulosa cell tumor presented with cervical varix. ► Cervical varix can potentially jeopardize the health of both the patient and fetus.

Cervical varices complicated by thrombosis in pregnancy

We present a case of a 36-year-old pregnant woman with varicose veins of the uterine cervix diagnosed during the second trimester. The cervical tissue was completely replaced with dilated venous plexus. Therapeutic decisions were further complicated by the presence of blood clots within the dilated vessels. Pregnancy proceeded uneventfully, no bleeding occurred and the patient underwent a planned Cesarean delivery. This is the first reported case in the medical literature where the rare phenomenon of cervical varices was accompanied by thrombosis.

Predisposing factors for massive hemorrhage during Cesarean section in patients with placenta previa

OBJECTIVES

To investigate whether maternal history and ultrasound findings can be predictors for massive hemorrhage during Cesarean section in patients with placenta previa and adherence of the placenta.

METHODS

We reviewed 127 singleton pregnancies with placenta previa. Maternal history, antenatal ultrasound findings of the placenta, including location, presence of placental lacunae, lack of a clear zone, presence of sponge-like findings of the cervix and presence of a marginal sinus in cases of placenta previa were reviewed retrospectively, and their association with amount of bleeding during Cesarean section was analyzed.

RESULTS

Logistic regression analysis revealed that advanced maternal age (odds ratio (OR), 5.4; 95% CI, 1.8-16.4), previous Cesarean section (OR, 20.4; 95% CI, 4.0-105.2) and sponge-like findings in the cervix (OR, 5.6; 95% CI, 1.8-17.0) were associated with massive bleeding (> 2500 mL). Placental adherence occurred in five cases and was more frequent in cases where the placenta was located at the site of the scar of a previous Cesarean section (OR, 123.1; 95% CI, 4.5-3395.2) and where there was lack of a clear zone (OR, 48.0; 95% CI, 3.8-604.7).

CONCLUSIONS

Advanced maternal age, previous Cesarean section and presence of sponge-like findings in the cervix are risk factors for massive bleeding during Cesarean section in cases of placenta previa, regardless of whether placental adherence is present. Placental location on the scar of a previous Cesarean section and lack of a clear zone are risk factors for placental adherence. When these findings are identified preoperatively, management should be tailored accordingly.

Incidental Findings During Routine Antepartum Obstetrical Sonography

The standard for performing an antepartum obstetrical sonogram primarily involves the examination of the fetus; however, both the American Institute of Ultrasound in Medicine (AIUM) and American College of Radiology (ACR) guidelines suggest the evaluation of maternal structures as well. The authors present 35 incidental findings that were discovered on routine antepartum obstetrical sonography. These include abdominal wall, gastrointestinal, reproductive, urinary, and vascular anomalies in the maternal structures. A review of the literature demonstrates that many of these findings have clinical significance, which highlights the wisdom of the AIUM and ACR guidelines, and it also stresses the importance of seeking and reporting them.
