Thoracic expansion techniques

Persistent air leaks in patients with pneumothorax can lead to significant morbidity. If a patient with persistent air leak is medically unfit for thoracic surgery, medical pleurodesis via chest tube or thoracoscopy is either an option. Thoracoscopy offers the advantage of visualizing the site of the air leak and enabling direct instillation of the pleurodesis agent or glue at that location. Autologous blood patch instillation via chest tube has been reported to be a cheap and very effective technique for the management of persistent air leaks...

The patient was a 48-year-old man who had undergone fenestrated frozen elephant trunk (FET) technique for acute type A aortic dissection. Postoperative enhanced computed tomography (CT) imaging revealed a type 1a endoleak from the fenestration. Nevertheless, the stented portion of the FET exhibited circular expansion. However, 2 months after surgery, enhanced CT imaging revealed the flattening of the FET due to the persistent endoleak and we performed an urgent zone 2 thoracic endovascular aortic repair (TEVAR)...

OBJECTIVE: Endovascular repair of chronic dissecting aortoiliac aneurysms is challenging given the rigid septum, compressed true lumen (TL), and target vessels frequently originating in the false lumen. We have used transcatheter electrosurgical aortic septotomy (TEAS) before stent graft implantation under intravascular ultrasound (IVUS) and fusion guidance. The purpose of this study is to assess the outcomes of TEAS during complex endovascular repair of dissecting aneurysms. METHODS: From 2021 to 2023, 17 patients underwent TEAS...

Total facial deformities always lead to psychological and functional consequences, making plastic and reconstructive surgery a great challenge. The skin of the anterior chest area is matched in thickness, texture, and color to the head and face. The purpose of this article was to discuss and evaluate reconstructive surgeons' experiences with obtaining a monoblock flap from the anterior thoracic area for entire face reconstruction using flap prefabrication, soft-tissue expansion, and facial plastic surgery following skin flap transplantation...

BACKGROUND: Redo-transcatheter aortic valve replacement (TAVR) can pin the index transcatheter heart valve leaflets open leading to sinus sequestration and restricting coronary access. The impact of initial implant depth and commissural alignment on redo-TAVR feasibility is unclear. We sought to determine the feasibility of redo-TAVR and coronary access after SAPIEN 3 (S3) TAVR stratified by implant depth and commissural alignment. METHODS: Consecutive patients with native valve aortic stenosis were evaluated using multidetector computed tomography...

BACKGROUND: This study aims to compare the clinical effects of two distinct surgical approaches, namely 3D printing-assisted extracorporeal pre-fenestration and Castor integrated branch stent techniques, in treating patients with Stanford type B aortic dissections (TBAD) characterized by inadequate proximal landing zones. METHODS: A retrospective analysis was conducted on 84 patients with type B aortic dissection (TBAD) who underwent thoracic endovascular aortic repair (TEVAR) with left subclavian artery (LSA) reconstruction at our center from January 2022 to July 2023...

OBJECTIVE: Mitral valve reconstruction in the pediatric population is a challenge due to the frequent combination of annular dilatation and leaflet restriction and the need for growth. We present a novel strategy using leaflet expansion and subpartial annuloplasty with polytetrafluoroethylene reinforcement. METHODS: From January 2014 through May 2021, 11 children aged 5 months to 14 years (median, 24 months) underwent elective mitral valve repair due to severe mitral valve regurgitation...

Aortic dissection often results in chronic aneurysmal degeneration due to progressive false lumen expansion. Thoracic endovascular aortic repair and other techniques of vessel incorporation such as fenestrated-branched or parallel grafts have been increasingly used to treat chronic postdissection aneurysms. True lumen compression or a vessel origin from the false lumen can present considerable technical challenges. In these cases, the limited true lumen space can result in inadequate stent graft expansion or restrict the ability to reposition the device or manipulate catheters...

Surgery for acute type A aortic dissection is highly challenging, even in expert hands. The goal in such emergency circumstances is primarily to save the patient's life. To minimize the perioperative risk, surgeons often choose surgery involving only supracoronary ascending aortic and hemiarch replacement. However, to achieve a successful repair, the extremely fragile dissected aortic layers must be reconstructed proximally and distally. Most of the surgical procedures for patients with acute type A aortic dissection are supracoronary ascending aortic replacements...

(1) Background: Technically, a simple, inexpensive, and non-invasive method of ascertaining volume changes in thoracic and abdominal cavities are required to expedite the development and validation of pulmonary mechanics models. Clinically, this measure enables the real-time monitoring of muscular recruitment patterns and breathing effort. Thus, it has the potential, for example, to help differentiate between respiratory disease and dysfunctional breathing, which otherwise can present with similar symptoms such as breath rate...

Uninterrupted monitoring of fetal cardiac health is essential for the timely diagnosis of congenital diseases. The maternal Electrocardiogram (mECG), which has the most significant impact, always tampers with the signals collected from the pregnant woman's abdomen. So, an efficient nonlinear filtering network based on artificial neural network (ANN) is required to eliminate the maternal part from the abdominal Electrocardiogram (aECG) that is traveled from the thoracic of the mother to the abdomen following nonlinear dynamics...

BACKGROUND: There continues to be a rise in the proportion of resectable non-small cell lung cancer (NSCLC) with the recent expansion of criteria for low-dose lung cancer screening. These are increasingly being treated with minimally invasive techniques. Our study aims to compare outcomes of robotic lobectomy (RL) for NSCLC at a National Cancer Institute-designated Comprehensive Cancer Center (NCI-CCC) to those of open lobectomy (OL), video-assisted thoracoscopic lobectomy (VL), or RL as reported in the National Cancer Database (NCDB)...

PURPOSE: The COVID-19 pandemic and its transition into an endemic phase have profoundly impacted physical health, well-being, mental health, education, and various aspects of society, including the economy and social networks. Home confinement, social distancing, and physical inactivity have exacerbated numerous health issues, including obesity, diabetes mellitus, hypertension, hyperlipidemia, cardiovascular diseases, depression, and poor sleep quality. A systematic review has revealed significant findings: Regular aerobic programs (such as cycling or walking at an intensity of 60-80% of HR max for 20-60 minutes per session, repeated 2-3 times a week) have proven effective in improving both physical and mental health, as well as immune function...

PURPOSE/OBJECTIVE(S): Advanced proton therapy techniques now allow for delivery of craniospinal irradiation (CSI) to the entire brain and thecal sac while sparing many of the anterior vertebral bodies from doses expected to inhibit growth, though this technique has not been prospectively studied. The purpose of this trial is to test the feasibility and robustness of vertebral body sparing (VBS) CSI in children with standard image guidance, to assess the dosimetric and toxicity benefits of this approach, and to report early clinical outcomes...

BACKGROUND: Meningiomas, although benign, often require complete resection due to their tendency for recurrence. However, dural reconstruction poses significant challenges, especially in the case of ventral meningiomas. While some reports have highlighted the usefulness of dural reconstruction using an artificial dura mater, no studies have yet confirmed dural canal enlargement through MRI post-surgically. This study aimed to assess the effectiveness of the Fenestrated Durotomy with Oversized Graft (FDOG) technique in cases of meningiomas and other intradural extramedullary tumors and evaluated dural canal dilation through MRI after using an artificial dura mater...

BACKGROUND: To compare the outcomes of two Thoracic Endovascular Aortic Repair (TEVAR) techniques of Left Subclavian Artery (LSA) reconstruction for Stanford Type B Aortic Dissection (TBAD) patients with undesirable proximal anchoring zone. METHODS: We retrospectively reviewed 57 patients with TBAD who underwent either three dimensional (3D)-printing-assisted extracorporeal fenestration (n = 32) or conventional extracorporeal fenestration (n = 25) from December 2021 to January 2023...

Basilar invagination is a rare pathology of the occipital bone, along with prolapsing of the vertebral column. It is a narrowing in the opening of the foramen magnum of the odontoid process. It is a well-known cause of pain and tingling in the upper limbs. However, only a few afflictions requiring physiotherapy rehabilitation in basilar invaginations have been reported. Thus, this study was carried out to investigate a case of basilar invagination. A 51-year-old female visited the neuro-outpatient department...

The identification of respiratory patterns based on the movement of the chest wall can assist in monitoring an individual's health status, particularly those with neuromuscular disorders, such as hemiplegia and Duchenne muscular dystrophy. Thoraco-abdominal asynchrony (TAA) refers to the lack of coordination between the rib cage and abdominal movements, characterized by a time delay in their expansion. Motion capture systems, like optoelectronic plethysmography (OEP), are commonly employed to assess these asynchronous movements...
