“…A number of recent studies conducted in Brazil have highlighted the importance of imaging methods in the evaluation of the female reproductive system (22)(23)(24)(25)(26)(27) . The use of microCT was pivotal to observing the vasculariza tion in detail.…”

Proportional vascularization along the fallopian tubes and ovarian fimbria: assessment by confocal microtomography

Abstract Objective: To evaluate and reconstruct three-dimensional images of vascularization along the fallopian tube (FT), as well as to determine its relationship with the ovary and ovarian fimbria, and to quantify the blood vessels along the FT according to its anatomical segments, using confocal microtomography (micro-CT). Materials and Methods: Nine specimens (six FTs and three FTs with ovaries) were fixed in a solution of 10% formalin for > 24 h at room temperature. Iodine staining was performed by soaking the specimens in 10% Lugol’s solution for 24 h. All specimens were evaluated using micro-CT. A morphometric analysis was performed on the reconstructed images to quantify the vascular distribution along the FT. Results: In the FTs evaluated, the density of blood vessels was significantly greater in the fimbrial segments than in the isthmic segments (p < 0.05). The ovarian fimbria was clearly identified, demonstrating the important relationship between these vessels and the FT fimbriae. Conclusion: We believe that the vascularization in the fimbriae is greater than and disproportional that in the other segments of FT, and that the ovarian fimbria plays an important role in the development of that difference.

“…On transvaginal or transabdominal pelvic ultrasound, an enlarged and edematous (hypoechoic) ovary may be seen in cases of torsion. [1][2][3][4] Classically, reduced flow is visible with color Doppler, the standard imaging technology deployed when ovarian torsion is being considered. 1 Flow can be significantly reduced or even nonexistent in cases where torsion progresses to infarction.…”

Case Presentationperimenopausal 52-year-old gravida 4, para 2 woman presented with chills, dysuria, pain with bowel movements, and intermittent right-sided abdominal pain. She had no urinary urgency or frequency, hematuria, or abnormal bowel movements. Initial imaging at an outside hospital reportedly revealed no relevant findings other than bilateral ovarian cysts. The patient received a referral for persistent lower abdominal and pelvic pain and, on physical exam, had right-lower quadrant pain and experienced tenderness upon palpation of that area. No mass was palpated. Grayscale and color Doppler ultrasound performed 11 days after initial imaging revealed a lack of flow to an enlarged, edematous right ovary (Figures 1A and 1B). T2-weighted MR images of the pelvis demonstrated hyperintense cystic areas within the same ovary and the corresponding para-ovarian fluid (Figures 2A and 2B). T1-weighted MR images revealed a peripheral rim of hyperintensity in the same ovary pre-contrast and asymmetric enhancement of the corresponding para-ovarian soft tissues post-contrast (Figures 2C and 2D).Diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) images showed diffusion restriction in the right ovary (Figures 2E and 2F). The patient was diagnosed with a hemorrhagic infarct of a torsed right ovary. She was treated conservatively, and her pain subsequently resolved.

“…varian Torsion (OT) has been known as the 5 th most prevalent emergency in the field of gynecology and can result in infertility in case of delayed or inappropriate treatment [1]. OT presents with partial or complete rotation of ligament of ovaries that leads to decreased blood flow, hemorrhagic infarction and necrosis [2,3]. This emergency condition require immediate surgery but the diagnosis might be complicated because of non-specific clinical presentation [4].…”

Background: Ovarian Torsion (OT) is a common gynecological emergency. Clinical presentation is nonspecific, and diagnosis is based on a high index of suspicion. Current recommendations strongly are based on ovarian support. Objectives: To assess clinical findings and therapeutic approach of patients diagnosed with OT. Materials & Methods: In this retrospective study 104 patients with confirmed OT in surgery were investigated. Clinical symptoms, laboratory indices, ultrasonography finding, and therapeutic approach were collected from hospital records of patients from 2001 to 2021. Results: The Mean±SD age of patients was 34.7±14.1 years old. The Mean±SD duration from hospitalization to surgery was 6.4±3 hours. The most common symptom in patients was abdominal pain (100%) followed by nausea and vomiting (76.9%). Ovarian cyst (71.2%) was the most gynecologic etiology of OT. Local tenderness (92.3%) and rebound tenderness (46.2%) were the most prevalent sign in physical examination. Necrotic ovary was found in 60 patients (57.7%) at surgery. Detorsion was possible in only 26 patients (25%). Conclusion: This study revealed that most objective findings in patients were nondifferential. The majority of patients with OT were in the reproductive ages, but just one fourth of them treated with conservative management.
