To determine the efficacy and safety of caesarean section combined with temporary aortic balloon occlusion followed by uterine artery embolisation (UAE) for the treatment of patients with placenta accreta. ⋯ Temporary aortic balloon occlusion followed by UAE can effectively control postpartum haemorrhage during placental dissection, and reduce transfusion requirements, hysterectomy rate, and operation time in patients with placenta accreta.

To evaluate the influence of number and location of catheter shaft side holes regarding drainage efficiency in an in vitro model. ⋯ The present in vitro study suggests that beyond a critical side hole number threshold, adding more distal side holes does not improve catheter drainage efficiency. These results may be used to enhance catheter design towards improving their drainage efficiency.

To evaluate image quality and diagnostic accuracy of different dual-energy computed tomography (DECT) datasets for identification of hepatocellular carcinoma (HCC), assess the reliability of virtual unenhanced (VU) images in replacing standard unenhanced (SU) images, and quantify effective dose (ED) at different tube voltages. ⋯ The 140 kVp dataset provided higher image quality. The 80 kVp images were more sensitive in detecting HCC. VU images are adequate in replacing SU images. The ED of the 80 kVp dataset was significantly lower.

To assess whether the application of a topical vapocoolant spray immediately prior to initial intradermal anaesthetic injection during ultrasound-guided breast biopsy decreases pain at the site of the initial injection. ⋯ Application of a topical vapocoolant spray immediately prior to initial intradermal anaesthetic injection during ultrasound-guided breast biopsy significantly decreases pain at the site of the initial injection and could contribute to improve the patient's overall procedural experience.
