B, Sagittal T2-weighted image shows hyperintense ectopic endometrial glands within thickened junctional zone (arrowheads) surrounding thin endometrial stripe (straight arrow) and hemorrhagic subendometrial cyst (curved arrow). Axial T2-weighted image shows hematometras (star), which was hyperintense on T1-weighted imaging (not shown). This can be accomplished using older first-generation resectoscopic endometrial ablation electrosurgical instruments including a rollerball electrode, wire-loop electrode, or vaporizing electrode or laser electrosurgical instruments, all of which require hysteroscopic guidance to ablate or resect the endometrium. Furthermore, even when endometrial tissue is obtained, histologic evaluation of the sample may be difficult [50–52]. Fig. One study showed that symptomatic patients tend to have a greater mean endometrial thickness than asymptomatic patients (6.0 vs 5.2 mm, respectively), although this difference is not statistically significant . Hysteroscopy revealed multiple adhesions. | C, Sagittal contrast-enhanced fat-suppressed T1-weighted image shows normal immediate postablation appearance: lack of enhancement of zones 1 and 2 and hyperemic outer junctional zone 3 (arrows). Historically, menorrhagia was treated surgically with hysterectomy, but hysterectomy has been displaced by endometrial ablation as the primary surgical alternative given its inherent advantages. Dans cet essai illustré, nous examinerons les caractéristiques visuelles normales et anormales de l'endomètre et les algorithmes de diagnostic servant à évaluer les saignements vaginaux anormaux et l’épaississement anormal de l'endomètre. These second-generation devices are also referred to globally as “endometrial ablation devices” and are now currently more widely used than resectoscopic endometrial ablation devices because of the shorter operative time, fewer technical challenges, and no requirement for general anesthesia [4, 5]. [The value of ultrasonography in diagnosis of atypical endometrial hyperplasia in postmenopausal women]. In this prospective study 571 patients with postmenopausal bleeding/discharge (group I) and 300 patients without symptoms (group II) were ultrasonographically examined. 1A —Schematics show device used for bipolar radiofrequency ablation (NovaSure, Hologic) of endometrium. In the United States, there is a greater incidence among patients of European descent compared those of African American descent. The endometrium also becomes hyperechoic starting from the periphery towards the centre.
Unilateral or bilateral cyclic lower abdominal or pelvic pain is localized to the side of the obstruction even though the patient may have amenorrhea. Adenomyosis can be missed on preprocedure ultrasound examinations, and there may be a role for MRI to more definitively exclude adenomyosis before ablation given the increased risk of treatment failure and of subsequent repeat surgery and the increased medical costs associated with these patients. The results of this study suggest that ablation either activates surviving endometrial tissue to penetrate the myometrium, thus causing adenomyosis, or activates the embedded ectopic endometrial glands to grow deeper into the myometrium resulting in deeper adenomyosis. Hysterectomy with proximal salpingectomy is the definitive treatment, and drainage of the hematosalpinx and cornual blood is rarely attempted [35, 42]. Depending on the volume of hemorrhage, blood products can be visualized within the cornua on ultrasound and CT. However, neither feeder vessel nor flow will be seen in these clots. The views expressed in this article are those of the authors and do not necessarily reflect the official policy or position of the Department of the Navy, Department of Defense, or the U.S. government. Baseline scans in women on the treatment for infertility are done on Day 2 or 3 of the menstrual cycle.
The evaluation of the endometrium and uterine cavity can be done both by TAS and TVS. Thickened endometrium with hyperechoic scattered foci within.
Outcomes at 2 and 5 years after ablation including rates of amenorrhea, patient satisfaction, and additional surgical treatment of menorrhagia were similar for both nonresectoscopic and resectoscopic endometrial ablation techniques; however, second-generation nonresectoscopic endometrial ablation devices appear to be marginally superior to the first-generation resectoscopic endometrial ablation devices [3, 16, 17].
When endometrial thickness should prompt biopsy in postmenopausal women without vaginal bleeding.
1997;168 (3): 657-61. Fig.
Deep adenomyosis can be responsible for a significant number of treatment failures after ablation, with patients often experiencing prolonged menorrhagia and dysmenorrhea after the procedure [26, 38, 43]. Destruction of the endometrial lining by resectoscopic or nonresectoscopic endometrial ablation techniques results in the clinical improvement of menorrhagia symptoms for most women; however, it also results in changes that eventually lead to the development of delayed complications in some patients.
B, Coronal T2-weighted image shows that band is intrauterine synechia as result of patient's prior ablation.
At times they are fleshy and large, and these could be adenomyomatous polyps. Differential diagnosis of central hematometras versus cystic degeneration of leiomyoma was reported, and patient was referred for MRI. B, Axial transvaginal sonographic image shows hypoechoic material distending endometrial cavities within cornua (stars) with increased through-transmission.
The uterus is scanned (on 2D) in the sagittal plane from one cornu to the other and in the transverse plane from the cervix to the fundus. Fig.

2). Menorrhagia, which can severely affect the quality of life, may affect up to 10 million American women each year [1, 2].
However, the incidence of both PATSS and cornual hematometra is likely underestimated because the clinical history is nonspecific unless a detailed surgical history is obtained at presentation.
Unlike ultrasound, MRI provides detailed evaluation of the zonal anatomy, and MRI is superior to ultrasound in the detection of adenomyosis . Intrauterine synechiae (arrows) are also evident. Operative and perioperative complications after ablation include uterine perforation, cervical laceration, hemorrhage, severe pelvic pain, and pelvic infection. NIH On MRI, the collections are localized to one or both cornua, and there may also be involvement and distention of the adjacent oviduct by blood products (i.e., hematosalpinx). Findings are consistent with cystic adenomyosis; cystic adenomyosis was confirmed at hysterectomy. CONCLUSION. Fig.
Intracavitary lesions should be measured in millimetres in three perpendicular dimensions (as explained in Chap. Long-term follow-up investigation  reported NovaSure to have better patient satisfaction, higher rates of amenorrhea [17, 20], and a lower occurrence of intraoperative and postoperative pain compared with the results of studies of thermal balloon ablation [20, 21].  evaluated the hysterectomy specimens of 51 patients who presented after ablation with recurring pelvic pain, menorrhagia, or both (22%, 43%, and 35%, respectively) as the chief complaint or complaints. Some authors also postulate that the presence of adenomyosis in postablation hysterectomy specimens is the result of endometrial islands located in the deep myometrium  or of activation and growth of residual surface endometrium into the myometrium . D, Axial fat-suppressed T2-weighted images show left cornual extension of hematometras (arrow, D), ectopic cluster of endometrial glands in junctional zone (arrows, E) consistent with adenomyosis, and fluid in bilateral fallopian tubes (arrowheads). Hysteroscopy is the method of choice for management. Sometimes clots within the endometrial cavity can mimic a polyp. The amount of intrauterine scarring has been shown to increase over time, which likely accounts for the delayed development of these complications . gynecological cancer whose incidence is increasing. Adenomyosis may develop de novo or may worsen after ablation in a select group of patients who present with postprocedural pelvic pain and bleeding.
