Recent technological advances have lowered the operational threshold for ECMO by enabling safer, more portable, and user-friendly systems. This article reviews the latest developments in ECMO-related technologies from the perspective of practicing clinicians. Key topics include the miniaturization and transportability of devices, improvements in centrifugal pumps and membrane lungs, and the incorporation of real-time monitoring and automatic control. Surface coatings using phosphorylcholine or hydrophilic polymers have enhanced biocompatibility and extended device longevity. Artificial intelligence and deep learning are being explored to assist in real-time decision-making and survival prediction. Furthermore, the potential for long-term implantable oxygenators is gaining attention. Our group has demonstrated prolonged in vivo function of a novel silicone membrane lung with methacryloyloxyethyl phosphorylcholine (MPC) polymer coating in large animal models, achieving thrombosis-free support for up to 100 days. The early conceptual framework for an implantable intrathoracic artificial lung, proposed by Mortensen in 1994, is gradually becoming technically feasible thanks to material and design innovations. These multifaceted advancements promise to broaden the future clinical applications of ECMO and improve outcomes across both acute and chronic indications.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

{"title":"[Medical Diagnostic Imaging].","authors":"Terunaga Inage, Hidemi Suzuki","doi":"","DOIUrl":"","url":null,"abstract":"Significant advancements in medical imaging technology have been made over the years. Currently, several commercial post-processing software solutions-such as Synapse Vinsent and Ziostation-are available to facilitate the creation of photorealistic three-dimensional (3D) images. Three-dimensional lung reconstruction with virtual modeling offers the opportunity to visualize tumors within the target segment or lobe and to confirm the bronchovascular anatomy, thereby enabling optimal surgical planning. Cross reality (XR)-which includes virtual reality (VR), augmented reality (AR), and mixed reality (MR)-enables surgeons to interact with computer-generated environments based on reality. In thoracic surgery, XR tools support anatomical assessment, surgical training through lifelike procedural simulations, preoperative planning, and intraoperative guidance. Lung perfusion scintigraphy with single photon emission computed tomography (SPECT-CT) allows for quantification of lobar perfusion during preoperative assessment of lung cancer candidates and provides a more accurate prediction of postoperative residual pulmonary function. Fractional flow reserve computed tomography (FFRCT) analysis is a non-invasive diagnostic tool used to determine the physiological impact of coronary artery disease (CAD) in patients with symptoms suggestive of CAD. The FFRCT has been demonstrated to reduce the necessity for invasive coronary angiography that shows no significant CAD. Coronary computed tomography angiography (CCTA) is a highly sensitive method of evaluating vascular anatomy, coronary plaque, calcification and stenosis. The pericoronary fat attenuation index (FAI), a new imaging biomarker derived from CCTA, assesses vascular inflammation by detecting respective gradients in coronary perivascular adipose tissue attenuation. Several studies have shown that elevated pericoronary FAI is associated with vascular inflammation and increased risk of cardiac events.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

However, complications such as infection, adhesion, and deformation of the materials, as well as hematoma caused by bleeding, chylothorax from lymphatic leakage, and pneumothorax or empyema due to air leaks, still occur at a certain rate. These issues indicate that the functions of currently available materials do not yet fully meet the needs of thoracic surgeons. In this article, we provide an overview of the classification, characteristics, and limitations of materials currently approved for use in Japan. Furthermore, we introduce recent advances in the development of novel materials-particularly surgical sealants-including an Alaska pollock gelatin sealant that we are co-developing for clinical application. In the development of new materials, improvements in physical properties, along with the availability of different formulations-such as liquid and sheet types-are expected to broaden their clinical applicability. The properties and limitations of each material are closely interrelated, and a thorough understanding of both is essential for optimal material selection and appropriate clinical use.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

{"title":"[Evolution and Future Prospects of Transcatheter Aortic Valve Implantation].","authors":"Hiromichi Sonoda, Akira Shiose","doi":"","DOIUrl":"","url":null,"abstract":"With the aging population, the prevalence of aortic stenosis (AS) is increasing, and transcatheter aortic valve implantation (TAVI) has become a promising treatment, particularly for high-risk patients. Over the past decade, TAVI technology has advanced rapidly, and three major devices-SAPIEN (balloon-expandable), Evolut (self-expanding), and Navitor (self-expanding)-are now widely used in Japan. Each device offers unique structural and procedural characteristics: SAPIEN provides precise positioning and strong anti-paravalvular leak features; Evolut offers excellent hemodynamics, especially in small annuli; and Navitor features a flexible delivery system and enhanced sealing via NaviSeal. Long-term data show favorable outcomes for all devices, though each has distinct advantages and limitations. Recent concerns include the management of younger patients and the rise in TAVI explant procedures. Thus, selecting the optimal device based on patient anatomy, risk profile, and future reintervention potential is increasingly emphasized. This review summarizes the key features and clinical outcomes of these devices and discusses future directions toward personalized treatment strategies, including lifetime management approaches. As TAVI expands to lower-risk and younger populations, balancing durability, procedural safety, and reintervention strategies will be essential to ensuring long-term clinical success.","PeriodicalId":17841,"journal":{"name":"Kyobu geka.
