It's a fundamental technique that cardiac surgeons must learn early in their training and execute safely. During the initial cardiac surgery, thorough detachment of the upper and lower ends of the sternum and precise identification of the sternal midline enable a safe sternotomy.

A 50-year-old woman with systemic lupus erythematosus and a history of aortic arch replacement surgery for Stanford type A aortic dissection experienced a reoccurrence of an ascending aortic aneurysm and coronary artery occlusion. Computed tomography revealed that the aneurysm was compressing the superior vena cava and right atrium. The patient underwent urgent surgery to repair the aneurysm.

Here, we present a case of multiple cervical and thoracic aortic aneurysms with right vocal fold palsy successfully treated with two-stage hybrid repair using retrograde in situ branched grafting.
Case Presentation: A 52-year-old patient with multiple cervical and thoracic aortic aneurysms and right vocal fold palsy was treated using two-stage hybrid repair.
Background: Systemic-to-pulmonary shunt is a palliative procedure used to decrease pulmonary blood flow in congenital heart diseases. Shunt stenosis or occlusion has been reported to be associated with mortality; therefore, the management of thrombotic complications remains a challenge for most congenital cardiovascular surgeons. Despite its importance, the optimal method for shunt anastomosis remains unclear.

Methods: A patient-specific aortic arch aneurysm model was constructed by using computed tomography scans. Three cannulas were assessed, as follows: dispersive with a steep angle, dispersive with a gentle angle, and the endo-hole type.
Background And Objective: Giant anterior mediastinal tumors sometimes may cause circulatory collapse and respiratory failure, known as mediastinal mass syndrome (MMS). The prediction and prevention of MMS is challenging. The aim of this study is to summarize the evaluation methods for MMS and formulate treatment strategies for giant anterior mediastinal tumors.

Methods: A retrospective study was conducted on 33 patients who underwent surgery for ATAADs between January 2020 and December 2021.
For the treatment and prevention of autoinflammatory diseases, it is essential to develop the drug, regulating the innate immune system. Although differentiation-inducing factor (DIF) derivatives, extracted from the cellular slime mold, Dictyostelium discoideum, exhibit immunomodulatory effects, their effects on the regulation of innate immunity in brain are unknown. In this study, we used the human cerebral microvascular endothelial cell line, hCMEC/D3, to investigate the effects of DIF derivatives on the generation of C-X-C motif chemokine (CXCL) 10 and interferon (IFN)-β induced by polyinosinic-polycytidylic acid (poly IC).

Background: Surgical pulmonary artery thrombectomy is a well-established emergency treatment for massive pulmonary embolism (PE) in which fibrinolysis or thrombolysis are not effective. However, surgery for massive PE that requires peripheral pulmonary artery thrombus removal remains challenging. We established a simple and secure pulmonary artery thrombectomy method using cardiopulmonary bypass and cardiac arrest.

However, she did not take oral anticoagulant for deep vein thrombosis prevention because of metrorrhagia. She developed pulmonary thromboembolism, and was refered to our department.

Background: Cerebral infarction after pulmonary resection is a minor but critical complication. We report a rare case of postoperative complication of Wallenberg syndrome caused by cerebral infarction in the posterior inferior cerebral artery after the left upper lobectomy.
Case Presentation: A 72-year-old man developed cerebral infarction 2 days after a left upper lobectomy for lung cancer.
This study clarifies the predicted subcutaneous shoulder depth and investigates the safety of the conventional (three-finger breadth method) and new (axillary method) intramuscular injection methods. The anatomical features of 245 volunteers who received the COVID-19 vaccination via the conventional method were investigated at the injection site (T point) and the hypothetical injection site using the new method (A point) via ultrasonography. The body mass index (BMI) and subcutaneous thickness at the T point (men: r = 0.

Methods: The subjects of this analysis were 77,060 patients who underwent curative lobectomy for lung cancer between 2016 and 2018 according to the National Clinical Database. Incidences of postoperative cerebral infarction and postoperative new-onset arrhythmia were analyzed.
Background: Giant mediastinal mature teratomas may cause airway obstruction or decreased venous return due to the mass effect. Preoperative stabilization of the respiratory and circulatory systems is important for perioperative management to safely perform surgery, including general anesthesia. However, to the best of our knowledge, there are only a few reports regarding the preoperative computed tomography (CT)-guided drainage of mediastinal tumors.

We have presented the case of a 76-year-old patient with a type V thoracoabdominal aortic aneurysm treated by retrograde in situ branched stent grafting to the superior mesenteric artery (SMA). Via a 9-cm, median laparotomy, a percutaneous transhepatic gallbladder drainage needle was inserted from the distal part of the first jejunal artery to the origin of the SMA. After stent graft placement into the aorta, the graft was retrogradely punctured using the percutaneous transhepatic gallbladder drainage needle.

Case Report: A 70-year-old woman with treated chronic type B aortic dissection was seen to have sac enlargement. An isolated residual tear was observed at the origin of the celiac artery.
Background And Aims: Surgery for extensive thoracic aortic aneurysms is challenging. We aim to report our novel extended arch repair method, which we termed "parabronchial approach" for such disease.
Materials And Methods: The patient case data was extracted from hospital records.
A 70-year-old man was admitted to our hospital with a thoracic aortic aneurysm. He underwent elective thoracic endovascular aneurysm repair with left common carotid artery-left subclavian artery bypass via the left supraclavicular approach. During the bypass, the thoracic duct was injured and ligated.
