During standard cadaveric dissection we encountered multiple vascular variations in the retroperitoneum: duplicated and dilated left ovarian vein with the coexistence of a persistent right mesonephric artery.

UNASSIGNED: Traumatic pelvic fractures are complex injuries often associated with significant morbidity and mortality. Among the complications of pelvic trauma, rupture of the ovarian vein represents a rare yet potentially life-threatening event. Prompt recognition and appropriate management are essential to mitigate the risk of hemorrhage and associated complications.
METHODS: We present a case of a 70-year-old woman who sustained a traumatic pelvic fracture following a skiing accident, resulting in rupture of the left ovarian vein. The patient came with the ambulance in the emergency room with lower abdominal tenderness, pelvic pain, but no signs of hemorrhagic shock. Imaging studies confirmed the diagnosis of a pelvic fracture with venous leakage of the left ovarian vein.
UNASSIGNED: This review synthesizes recent insights into the diagnosis, management, and complications associated with pelvic fractures, with an emphasis on optimizing patient outcomes through a multidisciplinary approach. The analysis incorporates findings from key studies, including those by Wong and Bucknill, Ma Y et al., and Tullington and Blecker, which advocate for the use of advanced diagnostic tools like CT scans and systematic evaluation processes. These studies underline the necessity of precise classification systems such as the Tile classification to guide treatment and predict outcomes.
CONCLUSIONS: Management of traumatic pelvic fractures with associated vascular injuries requires a multidisciplinary approach involving trauma surgeons, interventional radiologists, and critical care specialists. Early recognition, accurate diagnosis, and timely intervention are paramount in optimizing outcomes and reducing the risk of mortality. This case underscores the importance of prompt intervention and highlights the challenges associated with traumatic pelvic fractures and rupture of the ovarian vein. Further research is warranted to enhance our understanding of optimal management strategies and improve outcomes for patients with these complex injuries.

Retroperitoneal leiomyosarcoma (RPLMS) is rare and usually presents as a large abdominal mass with poor clinical symptoms. Radiological findings of an RPLMS arising in the pelvis of a woman resemble those of adnexal tumors. Herein, we present a case of RPLMS mimicking an adnexal tumor which was differentiated from having an ovarian origin as the right ovarian vein was passing through the tumor but there was no direct vascular connection with the tumor. Therefore, it is important to identify the ovarian vein to distinguish between these tumors.

OBJECTIVE: The purpose of this study was to evaluate the diagnostic value of colour Doppler sonography for ovarian veins. The clinical incidence of ovarian venous lesions is relatively low and often overlooked. The ovarian veins are located deep in the pelvis, and they are relatively elongated, which could make medical imaging more difficult. Therefore, there is limited literature on the diagnosis of ovarian venous disease. The purpose of this study was to evaluate the diagnostic value of colour Doppler sonography towards ovarian vein.
METHODS: A total of 37 consecutive patients with clinically suspected ovarian venous disorders were included. All the patients underwent colour Doppler sonography. CTV was performed in 31 patients, while retrograde phlebography was performed in 6 patients. CT/phlebography was the established diagnostic criterion for ovarian vein disorders. The SPSS 22.0 program was used for statistical analysis. Sensitivity, specificity, and positive and negative predictive values for colour Doppler sonography were calculated. k-test was used to evaluate consistency between colour Doppler sonography and CT/phlebography.
RESULTS: In the 37 patients,18 cases were positive for ovarian vein disorders and 19 cases were negative, as assessed with colour Doppler sonography. The associated lesions included ovarian vein thrombosis (7 cases), ovarian varicocele (3 cases), and ovarian venous leiomyoma (8 cases). The calculated values of sensitivity, specificity, and positive and negative predictive value were 94.4%, 94.7%, 94.4%, and 94.7%, respectively. The overall accuracy rate was 94.9%. The k level of the degree of agreement between CT/phlebography and colour Doppler sonography was 0.892.
CONCLUSIONS: Colour doppler sonography can provide sufficient imaging information. In clinical ultrasonography, attention should be paid to recognizing and detecting ovarian venous lesions.

The gonadal veins, responsible for draining from the paired gonads (testes in males and ovaries in females), exhibit variations in anatomy. Traditionally, the right gonadal vein directs its drainage into the inferior vena cava, while the left gonadal vein typically connects to the left renal vein. However, in the case of a 45-year-old woman diagnosed with a non-functional right kidney who underwent a right nephrectomy, an intraoperative observation revealed an unusual configuration: the right gonadal vein (ovarian) was found to drain directly into the right renal vein instead of its usual route into the inferior vena cava. This case report aims to elucidate this anomalous finding and provide a literature review on the prevalence of such anomalies in the existing research. This case report aims to raise awareness about the atypical drainage patterns of gonadal veins and underscore the importance of meticulous dissection of hilar renal vessels.

Intravascular leiomyomatosis (IVL) is a rare benign condition in which a leiomyoma, originating from the uterus, propagates through the pelvic venous system and occasionally extends into the inferior vena cava (IVC), occasionally reaching the heart. Despite its low incidence and benign nature, IVL can lead to life-threatening obstructions in the right heart\'s outflow tract, potentially resulting in sudden death. In this article, we present a case of a 72-year-old postmenopausal patient with IVL, who initially presented with palpitations. The diagnosis was made through echocardiography and a computerized tomography (CT) scan, revealing a tumor that extended from the uterus through the IVC and into the right ventricle. The patient was managed by a multidisciplinary team of gynecologists and cardiothoracic surgeons, who performed a single-stage surgical removal of a tumor 25 cm long. The pathological report confirmed the diagnosis of IVL. Postoperative follow-up is crucial, as IVL recurs in up to 30% of cases. This article\'s objective is to provide a clinical illustration of this exceedingly rare condition, with fewer than 300 reported cases, and to offer a comprehensive overview of IVL, including its clinical presentation, diagnosis, treatment, and outcomes.

OBJECTIVE: The management of pelvic venous disorders (PeVD) remains controversial. Open surgical and endovascular methods are currently used for treatment, but there are few data in the literature on the morphology and histology of the ectatic ovarian vein (OV). This study aimed to explore the histomorphological changes in a dilated OV in patients with PeVD and compare it with a normal OV obtained post-mortem and a normal great saphenous vein (GSV).
METHODS: Histology of the OV was studied in 16 patients who underwent surgery for PeVD, 10 control cadavers from whom fragments of the OV without visible gross changes were taken at autopsy, and nine control patients in whom the GSV was resected to be used for coronary artery bypass.
RESULTS: The OV wall in patients with PeVD consisted of three layers: intima, media, and adventitia. The OV looked very similar to the GSV wall because of a clearly developed layer of smooth muscle fibres. The thickness of the normal OV was significantly different to the OV wall in PeVD (475.3 μm, IQR 370.7, 607.6 vs. 776.3 μm, IQR 668.9, 879.6, p < .001) and did not differ significantly from the thickness of a normal GSV wall (784.3 μm, IQR 722.2, 898.2). The intima-media complex of the OV was significantly thinner than the GSV in PeVD (118.9 μm, IQR 75.6, 159.6 vs. 415 μm, IQR 399.5, 520.0, р < .001); however, the adventitia of the OV was significantly thicker than in normal OV and GSV (599.6 μm, IQR 444.3, 749.7 vs. 373.5 μm, IQR 323.8, 482.0 vs. 308.4 μm, IQR 275.9, 338.2, p < .001).
CONCLUSIONS: Dilatation of the OV in patients with PeVD was accompanied by a significant increase in the overall thickness of the vein wall, which brings it closer in structure to the GSV. This implies that the OV may be used safely for transposition into the inferior vena cava or iliac vein.

Late gestational supine positioning reduces maternal cardiac output due to inferior vena caval (IVC) compression, despite increased collateral venous return. However, little is known about the impact of maternal position on oxygen (O2 ) delivery and consumption of the gravid uterus, fetus, placenta and lower limbs. We studied the effects of maternal positioning on these parameters in 20 healthy pregnant subjects at 36 ± 2 weeks using magnetic resonance imaging (MRI); a follow-up MRI was performed 6-months postpartum (n = 16/20). MRI techniques included phase-contrast and T1/T2 relaxometry for blood flow and oximetry imaging, respectively. O2 transport was measured in the following vessels (bilateral where appropriate): maternal abdominal descending aorta (DAoabdo ), IVC, ovarian, paraspinal veins (PSV), uterine artery (UtA) and external iliacs, and umbilical. Maternal cardiac output was measured by summing DAothoracic and superior vena cava flows. Supine mothers (n = 6) had lower cardiac output and O2 delivery in the DAoabdo , UtA and external iliac arteries, and higher PSV flow than those in either the left (n = 8) or right (n = 6) lateral positions during MRI. However, O2 consumption in the gravid uterus, fetus, placenta and lower limbs was unaffected by maternal positioning. The ratio of IVC/PSV flow decreased in supine mothers while ovarian venous flow and O2 saturation were unaltered, suggesting a major route of pelvic venous return unaffected by maternal position. Placental-fetal O2 transport and consumption were similar between left and right lateral maternal positions. In comparison to non-pregnant findings, DAoabdo and UtA O2 delivery and pelvic O2 consumption increased, while lower-limb consumption remained constant , despite reduced external iliac artery O2 delivery in late gestation. KEY POINTS: Though sleeping supine during the third trimester is associated with an increased risk of antepartum stillbirth, the underlying biological mechanisms are not fully understood. Maternal cardiac output and uteroplacental flow are reduced in supine mothers due to inferior vena caval compression from the weight of the gravid uterus. This MRI study provides a comprehensive circulatory assessment, demonstrating reduced maternal cardiac output and O2 delivery (uteroplacental, lower body) in supine compared to lateral positioning; however, O2 consumption (gravid uterus, fetus, placenta, lower limbs) was preserved. Unlike other mammalian species, the ovarian veins conduct substantial venous return from the human pregnant uterus that is unaffected by maternal positioning. Lumbar paraspinal venous flow increased in supine mothers. These observations may have important considerations during major pelvic surgery in pregnancy (i.e. placenta percreta). Future studies should address the importance of maternal positioning as a potential tool to deliver improved perinatal outcomes in pregnancies with compromised uteroplacental O2 delivery.

This report addresses three variants identified within a female cadaver. Specifically, these were an anomalous origin of the right suprarenal artery, an abnormal bilateral ovarian vein branch, and a arterial tortuosity of the left ovarian artery. Indeed, the cadaver evinced abnormal origins in the case of the middle suprarenal artery (MSA), right inferior phrenic artery (IPA), and the renal capsule artery (emanating from the right renal artery). The MSA and IPA shared a common trunk with the inferior suprarenal artery. It was additionally observed that the right ovarian vein anastomoses the branches from the right kidney posterior inferior along with those to the renal fat capsule. Abnormal origin was evident in the case of the left ovarian artery, and arterial tortuosity was apparent in the lower region of the vessels. This report addresses both the clinical import of these variations and their likely causes. In the subdiaphragmatic region, surgical success and prognosis may be impacted by such anomalies; accordingly surgeons must be aware of anatomical variants of the ovarian and suprarenal arteries.

We present a unique case of a 56-year-old female with complex cloacogenic carcinoma history who experienced intraoperative episodes of ventricular tachycardia and pulselessness of unclear etiology. The etiology was later found to be related to a nephroureteral stent that had perforated the right ureter, entered the right ovarian vein, traversed up the inferior vena cava, and nestled in the right atrium.
