Abstract

In Twin-to-Twin Transfusion Syndrome (TTTS), abnormal vascular anastomoses in the monochorionic placenta can produce uneven blood flow between the two fetuses. In the current practice, TTTS is treated surgically by closing abnormal anastomoses using laser ablation. This surgery is minimally invasive and relies on fetoscopy. Limited field of view makes anastomosis identification a challenging task for the surgeon. To tackle this challenge, we propose a learning-based framework for in-vivo fetoscopy frame registration for field-of-view expansion. The novelties of this framework relies on a learning-based keypoint proposal network and an encoding strategy to filter (i) irrelevant keypoints based on fetoscopic image segmentation and (ii) inconsistent homographies. We validate of our framework on a dataset of 6 intraoperative sequences from 6 TTTS surgeries from 6 different women against the most recent state of the art algorithm, which relies on the segmentation of placenta vessels. The proposed framework achieves higher performance compared to the state of the art, paving the way for robust mosaicking to provide surgeons with context awareness during TTTS surgery.

Abstract

Fetoscopy laser photocoagulation is a widely adopted procedure for treating Twin-to-Twin Transfusion Syndrome (TTTS). The procedure involves photocoagulation pathological anastomoses to regulate blood exchange among twins. The procedure is particularly challenging due to the limited field of view, poor manoeuvrability of the fetoscope, poor visibility, and variability in illumination. These challenges may lead to increased surgery time and incomplete ablation. Computer-assisted intervention (CAI) can provide surgeons with decision support and context awareness by identifying key structures in the scene and expanding the fetoscopic field of view through video mosaicking. Research in this domain has been hampered by the lack of high-quality data to design, develop and test CAI algorithms. Through the Fetoscopic Placental Vessel Segmentation and Registration (FetReg2021) challenge, which was organized as part of the MICCAI2021 Endoscopic Vision challenge, we released the first largescale multicentre TTTS dataset for the development of generalized and robust semantic segmentation and video mosaicking algorithms. For this challenge, we released a dataset of 2060 images, pixel-annotated for vessels, tool, fetus and background classes, from 18 in-vivo TTTS fetoscopy procedures and 18 short video clips. Seven teams participated in this challenge and their model performance was assessed on an unseen test dataset of 658 pixel-annotated images from 6 fetoscopic procedures and 6 short clips. The challenge provided an opportunity for creating generalized solutions for fetoscopic scene understanding and mosaicking. In this paper, we present the findings of the FetReg2021 challenge alongside reporting a detailed literature review for CAI in TTTS fetoscopy. Through this challenge, its analysis and the release of multi-centre fetoscopic data, we provide a benchmark for future research in this field., Comment: Accepted at MedIA (Medical Image Analysis)

8. Truncating variants in PAPSS2 gene: A cause of early prenatal onset brachyolmia?

Author

Abstract

Brachyolmia is a rare form of skeletal dysplasia characterized by a wide genetic and clinical heterogeneity. This condition is usually diagnosed postnatally, and very few cases of prenatal diagnosis have been described so far. Here, we report a case of a pregnant woman at 20 weeks' gestation referred to our center because of fetal short long bones. On targeted ultrasound, mild bowing of the femurs and fibulae and mild micrognathia were also observed. Exome sequencing analysis showed the presence in compound heterozygosity of two pathogenic variants—both truncating variants—in the 3‐prime‐phosphoadenosine 5‐prime‐phosphosulfate synthase 2 (PAPSS2) gene, known to cause brachyolmia type 4 (OMIM #612847). Of note, all of the few cases reported prenatally have indeed truncating variants. Hence, we speculate this kind of variant is likely responsible for a complete loss of function of the protein leading to an earlier and more severe phenotype. Key points: What is already known on this topic? Brachyolmia shows a wide clinical heterogeneity and few cases have been described in fetuses. What does this study add? We report an early fetal diagnosis of brachyolmia, and speculate that the compound heterozygosity with two truncating mutations may be responsible for the prenatal onset of the bone shortening.
