The feasibility of thoracoscopic-guided intercostal nerve block during uniportal video-assisted thoracoscopic lobectomy of the lung.

Background: Uniportal thoracoscopic surgery has become widely accepted for its favourable outcomes with regard to pain. However, post-operative pain is still a concern associated with thoracic surgery. The objective of this study was to evaluate the post-operative pain of patients undergoing uniportal video-assisted thoracoscopic surgery (VATS) lobectomies using an intra-operative intercostal nerve block.

The Learning Curves of Uniportal Video-Assisted Thoracoscopic Surgery Lobectomy: A Single Center Experience.

The aim of our study is to describe the learning curve for uniportal video-assisted thoracoscopic surgery (VATS) lobectomy from our single center's experience for adopting it because uniportal VATS is generally considered a technically difficult procedure. A retrospective review of all 164 consecutive patients who underwent uniportal VATS lobectomy between June 2015 and February 2020 was done. A cumulative summation (CUSUM) method was applied to evaluate the learning curves of the operation time.

Subxiphoid single-port thymectomy: six-year experience of a single center.

Background: The subxiphoid single-port approach for thymectomy has several advantages compared with conventional lateral transthoracic approaches.

The objective of this study was to present our eight-year experience of uniportal VATS anatomical lung resection, including mid-term oncological outcomes.

Surgical treatment of micronodular thymoma with lymphoid stroma.

This case was about a 71-year-old man presented to our clinic for an anterior mediastinal mass found on routine chest computed tomography (CT). CT scan showed a lobulating contoured mass in the anterior mediastinum. A preliminary diagnosis was thymoma.

Isolated unilateral pulmonary artery agenesis presenting with massive hemoptysis.

This case was about a 21-year-old man with recurrent and persistent hemoptysis. Chest computed tomography scan showed a right-sided pulmonary artery agenesis and associated hypertrophic change of right side bronchial arteries. Thoracic aortogram revealed abnormal collateral arteries supplying the right lung.

Mediastinal venolymphatic malformations mimicking thymic carcinoma.

This report was about a 60-year-old asymptomatic female patient who presented to our clinic with an anterior mediastinal mass found on routine chest computed tomography (CT). Chest CT revealed an irregular poorly enhanced anterior mediastinal mass which showed signs of infiltration to adjacent structures with sparse calcifications. The preliminary diagnosis was thymic carcinoma.

Successful sleeve resection of bronchial carcinoid under veno-venous ECMO.

Here, we report a case of a bronchial tumor in the proximal left mainstem bronchus in a 19-year-old male. Diagnosis of the tumor was typical carcinoid, which was established by bronchoscopic biopsy preoperatively. Under femoral veno-venous extracorporeal membrane oxygenation (ECMO), the patient underwent left mainstem bronchus sleeve resection through median sternotomy.

Placental transmogrification of the lung presenting as a consolidative lesion with bronchiectasis.

A Prospective Randomized Trial Comparing Manual Needle Aspiration to Closed Thoracostomy as an Initial Treatment for the First Episode of Primary Spontaneous Pneumothorax.

Background: Variation exists in the initial treatment for the first episode of primary spontaneous pneumothorax (PSP), and no definitive consensus exists due to a lack of high-quality evidence. This study examined the outcomes of needle aspiration and closed thoracostomy in first episodes of PSP requiring intervention.

Methods: This study was a randomized, prospective, single-center trial conducted between December 2015 and August 2016.

Surgical Repair of Aortocaval Fistula Presenting with Cardiogenic Shock.

Aortocaval fistula (ACF) occurs in <1% of all abdominal aortic aneurysms (AAAs), and in 3% to 7% of all ruptured AAAs. The triad of clinical findings of AAA with ACF are abdominal pain, abdominal machinery bruit, and a pulsating abdominal mass. Other findings include pelvic venous hypertension (hematuria, oliguria, scrotal edema), lower-limb edema with or without arterial insufficiency or venous thrombus, shock, congestive heart failure, and cardiac arrest.

A New Root-Strengthening Technique for Acute Aortic Dissection with a Weakened Aortic Root: The Neo-Adventitia Technique.

Background: Dissection flaps in acute type A aortic dissection typically extend into the root, most frequently into the non-coronary sinus (NCS). The weakened root can be susceptible not only to surgical trauma, but also to future dilatation because of its thinner layers. Herein, we describe a new technique that we named the "neo-adventitia" technique to strengthen the weakened aortic root.

Feasibility and Safety of Single-Port Video-Assisted Thoracic Surgery for Primary Lung Cancer.

Background: The feasibility of single-port video-assisted thoracic surgery (SPVATS) for primary lung cancer is not well understood. In this study, we compared SP and multi-port (MP) VATS for the surgical treatment of patients with primary lung cancer.

Methods: Surgical treatment was performed in 181 patients with primary lung cancer at Inje University Haeundae Paik Hospital between June 2012 and December 2015.

Acute Limb Ischemia and Coronary Artery Disease in a Case of Kimura's Disease.

Kimura disease (KD) is an immune-mediated chronic inflammatory disease of unknown etiology. KD has many complications associated with hypereosinophilia, including various forms of allergic reactions and eosinophilic lung disease. Additionally, hypereosinophilia is associated with hypercoagulability, which may lead to thromboembolic events.

A New Surgical Repair Technique for Ischemic Total Papillary Muscle Rupture.

Papillary muscle (PM) rupture is an emergency surgical condition that may occur after acute myocardial infarction. In patients with compete rupture of the PM, mitral valve replacement is preferred or recommended generally because of unstable vital signs or technical difficulties with successful repair, as compared with patients with partial PM rupture. This case report describes the successful repair of a complete anterolateral PM rupture by using the single PM formation technique with subsequent ring annuloplasty.

Long Segmental Reconstruction of Diffusely Diseased Left Anterior Descending Coronary Artery Using Left Internal Thoracic Artery with Extensive Endarterectomy.

In coronary artery bypass grafting, a diffusely diseased left anterior descending coronary artery (LAD) is an obstacle to achieving complete revascularization, consequently leading to the possibility of a poor prognosis. Long segmental reconstruction with or without endarterectomy is a revascularization method for treating diffusely diseased coronary arteries. Herein, we report a successful case of long segmental reconstruction of a diffusely diseased LAD using a left internal thoracic artery onlay patch after endarterectomy.
