Open Aortic Repair After Thoracic Endovascular Aortic Repair: Strategic Insights From a Single Centre Surgical Experience.
EJVES Vasc Forum
December 2024
Department of Cardiovascular Surgery, Sapporo Medical University, Sapporo, Hokkaido, Japan.
Objective: Thoracic endovascular aortic repair (TEVAR) is widely used in thoracic aortic surgery. However, for various reasons some patients require secondary open aortic repair. Herein, the surgical outcomes and problems of such open conversion surgery after TEVAR are investigated.

The thoracic paravertebral block (TPVB), while relatively safe, can be associated with significant complications, including inadvertent vascular injury. We describe an ultrasound-guided TPVB where a pulsatile artery was identified between the two transverse processes and in close proximity to the T7-8 paravertebral space, likely the dorsal branch of the posterior intercostal artery. A similar artery was also noted one intercostal space cephalad and caudal of this area.

Latissimus dorsi flaps are typically vascularized by the thoracodorsal or intercostal artery perforators, while cases describing the use of lumbar artery perforators are exceedingly rare. This report presents a case of a 74-year-old woman presenting with a refractory ulcer associated with an exposed lumbar spinal fixation device. Reconstruction was successfully performed using a pedicled latissimus dorsi flap vascularized by lumbar artery perforators.

The operative field and exposure in minimally invasive cardiac surgery (MICS) are limited. Meticulous preoperative planning and intraoperative visualization are crucial. We present our initial experience with HoloLens 2 as an intraoperative guide during MICS procedures: aortic valve replacement (AVR) via right anterior small thoracotomy, coronary artery bypass graft surgery (CABG) via left anterior small thoracotomy (LAST), and pulmonary valve replacement (PVR) via LAST.

Objective: This study aims to explore the application value of chest wall perforator flaps (CWPF) in oncoplastic breast-conserving surgery.
Methods: A retrospective review was conducted on 22 early-stage breast cancer patients who underwent oncoplastic breast-conserving surgery using CWPF between January 2021 and December 2022. This included 4 cases (18.
