Novel endovascular techniques hope to offer patients aortic arch repair with reduced morbidity compared to conventional arch surgery; however, current endovascular strategies remain challenged by the proximal seal zone, higher stroke rates, long-term durability and select anatomy. Hybrid arch repair offers patients a less invasive alternative that can treat more distal aorta than conventional arch repair yet still be performed via standard sternotomy. Areas Covered: This review will discuss the current evidence and future development of hybrid aortic arch and frozen elephant trunk reconstruction...

Ionic liquids (ILs) are regarded as ideal components in the next generation of strain sensors because their ultralow modulus can commendably circumvent or manage the mechanical mismatch in traditional strain sensors. In addition to strain sensors, stretchable conductors with strain-insensitive conductance are also indispensable in artificial systems for connecting and transporting electrons, similar to the function of blood vessels in the human body. In this work, two types of ILs-based conductive fibers were fabricated by developing hollow fibers with specific micro-scale channels which were then filled with ILs...

Although vocal cord paralysis (VCP) following thyroidectomy is primarily associated with surgical trauma, it is not the sole etiology. Vocal cord paralysis following thyroidectomy can be caused by a vocal cord hematoma with an incidence of 1.4% due to direct injury during orotracheal intubation. In this article, we present a case of VCP caused by vocal cord hematoma. A 32-year-old male patient who has been receiving propylthiouracil treatment for toxic multinodular goiter since 10 years was admitted to our hospital to be operated because of persisting complaints...

Luca Garriboli, Antonio Maria Jannello
PURPOSE: To describe the application of uncovered chimney stent grafts with the Nellix endovascular aneurysm sealing technique (ChEVAS) for juxtarenal abdominal aortic aneurysms (JAAAs). CASE REPORT: Two patients with JAAA and multiple comorbidities were considered unfit for open surgery and were selected for an endovascular approach. Fenestrated and branched endografts were too expensive, and a chimney endovascular approach was considered inappropriate for the relatively high incidence of proximal type I endoleak and graft migration...

PURPOSE: Thoracic endovascular aortic repair (TEVAR) is the preferred treatment of descending thoracic aorta pathology. However, TEVAR in the aortic arch remains challenging. Customized fenestrated TEVAR (fTEVAR) allows extension of the proximal seal zone, while preserving the involved supra-aortic vessels. There is a paucity of information on fTEVAR; hence, we aim to evaluate our early experience and lessons learnt with fTEVAR in the aortic arch. METHODS: This is a retrospective single-centre review of fTEVAR endografts for aortic arch pathology over 24 months...

Platelets play a central role in primary hemostasis by forming aggregates that plug holes in injured vessels. Half a century ago, detailed studies of the microvasculature by electron microscopy revealed that under inflammatory conditions that do not induce major disruption to vascular structure, individual platelets are mobilised to the vessel wall, where they interact with leukocytes and appear to seal gaps that arise between endothelial cells. Recent developments in genetic engineering and intravital microscopy have allowed further molecular and temporal characterization of these events...

We report here the design and multiple functions of a new hierarchical nanotheronostic platform consisting of an upconversion nanoparticle (UCNP) core: shell with an additional mesoporous silica (mSiO2) matrix load shell containing sealed, high concentration of ICG molecules. We demonstrate that this UCNP@mSiO2-ICG nanoplatform can perform the following multiple functions under NIR excitation at 800 nm: 1) Light harvesting by the UCNP shell containing Nd and subsequent energy transfer to Er in the Core to produce efficient green and red upconversion luminescence for optical imaging; 2) Efficient nonradiative relaxation and local heating produced by concentration quenching in aggregated ICG imbedded in the mesopourous silica shell to enable both photoacoustic imaging and photothermal therapy...

The chimney technique can be combined with thoracic endovascular aortic repair (TEVAR) to both obtain an appropriate landing zone and maintain blood flow of the arch vessels. However, surgical repair becomes more complicated if retrograde type A aortic dissection occurs after TEVAR with the chimney technique. We herein report a case involving a 73-year-old woman who developed a retrograde ascending dissection 3 months after TEVAR for acute type B aortic dissection. To ensure an adequate proximal sealing distance, the proximal edge of the stent graft was located at the zone 2 level and an additional bare stent was placed at the left subclavian artery (the chimney technique) at the time of TEVAR...

STUDY OBJECTIVE: Lumboaortic lymphadenectomy is frequently performed in the surgical management of different gynecologic pelvic malignancies: cervical endometrial and ovarian cancer. The retroperitoneal access presents a real advantage, allowing direct access to vascular axes, thus avoiding bowel segments. The use of a vessel-sealing device could facilitate the technique by providing an ergonomic alternative to conventional tools such as a bipolar grasper and scissors. Here the surgical technique of laparoscopic retroperitoneal lumboaortic lymphadenectomy using a vessel-sealing device in 10 steps is described...

Intraoperative bleeding is one of the main severe complications in complete video-assisted thoracic surgery (c-VATS) and post-operative air-leaks prevention still represents an important challenge. Usually, hemostasis is often difficult and unsafe when the VATS approach is performed and the potential role of bipolar sealing devices is still undefined, as proven by limited experiences reported in the literature. By introducing endostaplers in VATS surgery, it was possible to perform safe thoracoscopic resections of lung...
