Background/aim: Hepatic artery anastomosis (HAA) is the most important aspect of living donor liver transplantation (LDLT), and it is currently performed by a specialized microsurgeon using micro surgical techniques, with interrupted sutures and the aid of an operative microscope. To simplify the procedure, we studied a new, simpler technique performed by pediatric transplant surgeons with continuous sutures and the same 3.5× magnification loupe used during other transplant procedures. The aim of this study was to compare these two hepatic artery reconstruction techniques in two pediatric LDLT series.
Methods: This study was initiated in January 2010 and finished in June 2013. In the first period, the arterial reconstruction was performed with an operating microscope and the classical technique of 9-0 separate sutures. In the second period, the arterial reconstruction was performed using a simpler technique, with surgical loupe and continuous 8-0 Prolene sutures. The incidences and outcomes of complications within the two periods were analyzed and compared.
Results: A total of 82 LDLTs were performed, 38 in the first period and 44 in the second period. There were no differences between the periods, except for the arterial ischemia time, which was lower in the second period.
Conclusion: Hepatic artery anastomosis can be safely performed with low complication rates by a pediatric transplant surgeon using continuous sutures with a 3.5× magnifying loupe. This technique is simpler, less time consuming and simplifies the complex pediatric LDLT procedure.

Purpose: During endovascular revascularization interventions for peripheral arterial disease, the standard modality of X-ray fluoroscopy (XRF) used for image guidance is limited in visualizing distal segments of infrapopliteal vessels. To enhance visualization of arteries, an image registration technique was developed to align pre-acquired computed tomography (CT) angiography images and to create fusion images highlighting arteries of interest.
Methods: X-ray image metadata capturing the position of the X-ray gantry initializes a multiscale iterative optimization process, which uses a local-variance masked normalized cross-correlation loss to rigidly align a digitally reconstructed radiograph (DRR) of the CT dataset with the target X-ray, using the edges of the fibula and tibia as the basis for alignment.

Background: Paragangliomas are rare neoplasms arising from extra-adrenal chromaffin cells, with mediastinal paragangliomas representing an exceptionally rare subset. This report details the surgical management of a complex mediastinal paraganglioma case, presenting with refractory hypertension and invasion of critical surrounding structures. A comprehensive review of the current literature is included to underscore existing cases, enhance clinical awareness, and share our insights and experience in the diagnosis and treatment of this challenging condition.

Background: Pulmonary artery sling (PAS) is a rare congenital anomaly where the left pulmonary artery (LPA) branches from the right pulmonary artery, compressing the trachea and esophagus and frequently leading to respiratory distress in infants. Surgical intervention, such as LPA reimplantation or translocation, is crucial to relieve airway compression and restore normal pulmonary function.
Case Presentation: This report highlights varied LPA anatomies, including a unique case of an anomalous LPA without true sling formation but causing tracheal compression, alongside two typical PAS cases.

Unlabelled: Carotid Blowout Syndrome (CBS) is a rare and life-threatening condition that necessitates prompt intervention to prevent fatal hemorrhage. This study compares the outcomes of two primary endovascular approaches: reconstructive interventions, which aim to preserve carotid artery function using stents or balloon angioplasty, and deconstructive interventions, which involve vessel occlusion to halt bleeding. A systematic review and meta-analysis were performed by searching multiple databases for relevant studies published from January 2000 to August 2023.

Background: During infant aortic arch reconstruction, traditional electroencephalography (EEG) provides only qualitative data limiting neuromonitoring efficacy. Interhemispheric differences in the alpha:delta ratio (ADR) and suppression ratio (SR) measured using quantitative EEG generate numerical trends that may suggest cerebral ischemia. We hypothesized that the ADR and SR during cardiopulmonary bypass (CPB) would correlate with hemodynamics, and that ADR and SR interhemispheric differences would precede neurological injury from infants requiring aortic arch reconstruction.
