Predictive Factors of a Dominant Superficial Venous Drainage System in DIEP Flap Surgery With Preoperative Computed Tomography Angiography.

Microsurgery

January 2025

Service de Chirurgie Plastique, Hôpital Européen Georges Pompidou, Assistance Publique-Hôpitaux de Paris (APHP), Université Paris Descartes, Paris, France.

Background: Venous congestion due to superficial venous system dominance (SVD) in deep inferior epigastric perforator (DIEP) flap surgery occurs in approximately 2% of cases, with attendant sequelae and increased cost to healthcare systems. This study aimed to describe the predictive factors for SVD in DIEP flap breast reconstruction based on preoperative computed tomography angiography (CTA) findings.

Methods: All women who required takebacks for additional venous anastomosis to the cephalic vein because of SVD after DIEP flap breast reconstruction between 2015 and 2022 were included.

For gastric leiomyomas measuring ≥5 cm, endoscopic resection is necessary. The larger size of these tumors significantly impairs the resection field of view, increasing the risk of intraoperative bleeding and perforation and potentially leading to incomplete tumor removal. The combination of dental floss and tissue clip traction techniques is commonly used for resecting mucosal lesions but is rarely reported for submucosal tumors.

Rotablator-associated coronary perforation can be fatal if bailout is delayed. Successful bailout is typically defined as the disappearance of contrast extravasation after a haemostatic intervention. We report a case of recurrent cardiac tamponade in the subacute phase, wherein haemostasis appeared to have been achieved on angiography following the implantation of a covered stent during the index procedure.

Purpose: Mechanical thrombectomy (MT) for distal medium vessel occlusions (DMVOs) in the middle cerebral artery (MCA) is less established than for large vessel occlusions. This study evaluates the safety and efficacy of MT in DMVOs, comparing it with M1-segment occlusions.

Materials And Methods: This retrospective study analyzed 218 patients who underwent MT for isolated M1 (n=123) or distal M2+M3 (n=35) occlusions between January 2020 and August 2023.

Background: Support for the treatment of uncomplicated appendicitis with non-operative management rather than surgery has been increasing in the literature. We aimed to investigate whether treatment of uncomplicated appendicitis with antibiotics in children is inferior to appendicectomy by comparing failure rates for the two treatments.

Methods: In this pragmatic, multicentre, parallel-group, unmasked, randomised, non-inferiority trial, children aged 5-16 years with suspected non-perforated appendicitis (based on clinical diagnosis with or without radiological diagnosis) were recruited from 11 children's hospitals in Canada, the USA, Finland, Sweden, and Singapore.
