Digital variance angiography (DVA), a recently developed image processing technology, provides higher contrast-to-noise ratio (CNR) and better quality during lower limb interventions than digital subtraction (DSA). Our aim was to investigate whether the reserve of DVA can also be observed in uterine fibroid embolization (UFE). In this retrospective observational study, CNR DSA images from 56 patients (mean ± standard deviation age: 44.2 5.3 years) who underwent UFE at our institution were...

Objectives To assess whether strain elastography may be used to visualize the different stiffness of endometrial polyps and submucosal fibroids. Methods We conducted a prospective monocentric single‐operator study on diagnostic accuracy. Patients who qualified for hysteroscopy because suspected fibroids were included. Before procedure, all patients underwent routine sonographic power Doppler examinations. Additionally, intrauterine lesions was assessed by elastography. The enhancement...

Uterine fibroids are benign tumors originating from smooth muscle tissue, constituting uterine stroma. the most common found in women. In 20%–50% of women, asymptomatic and do not require any treatment. The main symptoms profuse menstrual bleeding, abnormal pressure symptoms. Pressure can cause pelvic pain syndrome, urination disorders, constipation. treatment methods that currently used include surgical treatment, pharmacological therapy, minimally invasive procedures. commonly applied...

A pregnancy located within a cesarean scar is the rarest form of ectopic pregnancy. We present case 34-year-old woman with history one section (gravida 2, para 1) admitted to hospital at 9 weeks gestation due vaginal bleeding, initially diagnosed as missed abortion. During hospitalization spontaneous abortion took place, and patient was qualified for dilatation curettage. After procedure massive bleeding occurred, diagnosed, uterine artery embolization (UAE) using gelatin sponge particles...
