Placental polyp with prominent neovascularization

Cervico-Isthmic Pregnancy: Early Diagnostic Imaging and Successful Dual Therapy for Uterine-Sparing Treatment

“…Along with improved scanner speed after the introduction of multirow detector CT scanners and the ability to create thin-section images, recently evolving 3-dimensional CT angiography could be a useful modality for diagnosing abnormal placentation associated with vascular disorders and is replacing more invasive diagnostic pelvic angiography as an initial diagnostic measure [11,12]. In the present cervico-isthmic pregnancy with massive hematometra, uteroplacental neovascularization could be precisely evaluated by 3-dimensional CT angiography, when the potential risk of hemorrhage during conservative management was assumed to be high owing to increased blood flow around the gestational products by color Doppler ultrasonography.…”

“…Although the value of TACE for the management of cervico-isthmic pregnancy has not yet been established, it could be a feasible option as an adjunctive preoperative measure instead of methotrexate therapy before surgical resection of low-lying implantation, because immediate and efficient devascularization has already been demonstrated for the management of cesarean scar pregnancy [11], retained gestational products forming a placental polyp [12], and proximal interstitial pregnancy [19]. Although recanalization of the embolized arteries and the development of an aberrant blood supply should be carefully monitored even after successful devascularization, as in the present case, TACE could be a feasible interventional option when hysteroscopic resection of an early cervico-isthmic gestational mass with prominent neovascularization is attempted.…”

“…Because it was assumed that gestational products are resistant to cytotoxic and angiographic interventional therapy in this case, hysteroscopic resection of the gestational mass was performed as well [12]. The uterine cavity was inspected using a continuous-flow resectoscope with an outer diameter of 8 mm (Karl Storz Endoscopy Japan, Tokyo, Japan) with distension by sorbitol medium (Uromatic S; Baxter Ltd., Tokyo, Japan) by gravity flow.…”

Placental polyp - a rare case report

“…UsG imaging of the placental polyp shows a heterogenous polypoid mass with prominent vascular flow (8). MrI and power Doppler imaging can more accurately detect abundant blood supply of the placental polyps rather than conventional color Doppler signal UsG (9).…”

Placental polyp: a diagnostic dilemma

“…17 Takeda A et al in another study included seventeen women with suspected placental polyp in this retrospective study. Neovascularization in placental polyp tissue was assessed by computed tomographic angiography.…”
