MRI-guided biopsies are being increasingly used for otherwise occult breast lesions. Clip migration has been reported however, to the best of our knowledge, there have been no documented cases of entire disappearance of a marker clip. Absence of the postbiopsy marker clip was noted when our patient returned for preoperative hook-wire localisation even though accurate clip placement had been confirmed on the post-MRI biopsy mammogram.

This study aimed to evaluate the diagnostic accuracy of ultrasonography in assessing the response of clipped axillary lymph nodes to neoadjuvant chemotherapy. Between February 2022 and September 2023, 43 patients who underwent axillary lymph node marking for targeted axillary dissection were retrospectively analyzed. Ultrasonography parameters such as the number, size, shape, cortical thickness, hilum status, and treatment response of the clipped lymph node were assessed.

Background And Aims: Transcatheter arterial embolization (TAE) is recommended for refractory peptic ulcer bleeding. There are 46% of patients showed no detectable contrast extravasation during TAE. Endoscopic clip in bleeding lesion is visible and could be used as a marker in TAE.

Patient-specific implant placement in the case of pelvic tumour resection is usually a complex procedure, where the planned optimal position of the prosthesis may differ from the final location. This discrepancy arises from incorrect or differently executed bone resection and improper final positioning of the prosthesis. In order to overcome such mismatch, a navigation solution is presented based on an augmented reality application for HoloLens 2 to assist the entire procedure.
View Article and Find Full Text PDFIn percutaneous pelvic trauma surgery, accurate placement of Kirschner wires (K-wires) is crucial to ensure effective fracture fixation and avoid complications due to breaching the cortical bone along an unsuitable trajectory. Surgical navigation via mixed reality (MR) can help achieve precise wire placement in a low-profile form factor. Current approaches in this domain are as yet unsuitable for real-world deployment because they fall short of guaranteeing accurate visual feedback due to uncontrolled bending of the wire.
