    Abstract Introduction: Boerhaave Syndrome (BS) is rare but life-threatening condition caused by a sudden increase in the intraluminal pressure due to vomiting. We present a case of BS manifesting as a posterior mediastinal hematoma, indicative of a potentially fatal condition.
    Presentation of case: A 51-year-old man presented with acute chest pain after vomiting. Enhanced Computed Tomography revealed mediastinal fluid with a left pleural effusion, leading to a diagnosis of BS. Emergency surgery revealed a posterior mediastinal hematoma with active bleeding due to a torn proper esophageal artery. Hemostasis and a wall repair were performed, and the patient was discharged uneventfully.
    Discussion: This case highlights two important aspects. Firstly, a spontaneous esophageal perforation can manifest as a mediastinal hematoma due to the subpleural arterial injury, delaying bacterial spillage. While preoperative thoracentesis may not always diagnose BS accurately, bloody thoracic drainage can serve as an alternative diagnostic sign. Secondly, the mediastinal hematoma itself poses a serious risk, as it can lead to a catastrophic outcome even before bacterial contamination occurs, emphasizing the necessity of a timely surgical intervention in BS cases.
    Conclusion: BS can manifest as a mediastinal hematoma, and the absence of gastrointestinal content in the thoracic drainage does not rule out the possibility of BS. Prompt surgical intervention remains essential, as a mediastinal hematoma alone can result in a catastrophic outcome. This case highlights the significance of a comprehensive diagnostic assessment for BS.

    Abstract A 74-year-old woman had been on hemodialysis for about 2 months using a short-term indwelling dialysis catheter due to chronic kidney disease. A 20 mm-diameter left atrial neoplastic lesion was noted during a screening echocardiogram performed at the time of induction of hemodialysis. The lesion rapidly increased to 30 mm 2 months later and was referred to our hospital for surgical resection. Under cardiopulmonary bypass and cardiac arrest, tumor resection was performed. Although the lesion was myxomatous with a thin stalk on the left atrial ceiling, the pathological diagnosis was thrombus. After the initiation of anticoagulation, the patient was discharged.

    Abstract A pulmonary arteriovenous fistula (PAVF) is a direct abnormal connection between the pulmonary artery and pulmonary vein, lacking capillary tissue. On the other hand, a pulmonary venous aneurysm (PVA) is a localized dilation and aneurysmal formation in the pulmonary vein without reflux issues. Treatment approaches for PAVF and PVA differ, considering surgery or catheter embolization for PAVF due to the risk of cerebral infarction or rupture caused by the abnormal shunt. PVA cases, being rare in rupture and embolism, are usually recommended for observation. Therefore, distinguishing between these two conditions is crucial. This article presents a case where both PVA and PAVF were present, necessitating a differential diagnosis.

    Abstract Anomalous systemic arterial supply to the left basal lung is a rare congenital lung malformation, and its optimal treatment strategy is not well defined. We present a case of a 61-year-old man who underwent thoracic endovascular aortic repair (TEVAR) for anomalous systemic arterial supply to the left basal lung complicated with aneurysmal dilatation of the aberrant feeding artery. Computed tomography angiography after TEVAR revealed significant shrinkage of the aneurysmal portion as well as complete occlusion of the aberrant feeding artery. TEVAR proved to be a safe and efficient treatment for this rare arterial abnormality.

    Abstract The molecular crowding effect on ligand-protein interactions, which plays several crucial roles in life processes, has been investigated using various models by adding crowding agents to mimic the intracellular environment. Several studies evaluating this effect have focused on the ligand-protein binding reaction of well-structured binding sites with rigid conformations. However, the crowding effect on flexible binding sites is not well-understood, especially in terms of the conformations. In this work, to elucidate the detailed molecular mechanism underlying the ligand-protein interactions with flexible binding sites on a protein surface, we studied the interaction between the basic protrusion of

    Abstract Purpose: To evaluate the accuracy of needle placement using a three-dimensional (3D) augmented reality (AR) protractor on smartphones (AR Puncture).
    Materials and methods: An AR protractor that can be rotated in three directions against the CT plane with angle guidance lines for smartphones was developed. The protractor center can be adjusted to an entry point by manually moving the smartphone with the protractor center fixed at the center of the screen (Fix-On-Screen) or by image tracking with a printed QR code placed at an entry point (QR-Tracking). Needle placement was performed by viewing a target line in the tangent direction with the Bull's eye method. The needle placement errors placed by four operators in six out-of-plane directions in a phantom using a smartphone (iPhone XR, Apple, Cupertino, CA, USA) were compared with two registration methods.
    Results: No significant difference in the average needle placement error was observed between the Fix-On-Screen and QR-Tracking methods (5.6 ± 1.7 mm vs. 6.1 ± 2.9 mm, p = 0.475). The average procedural time of the Fix-On-Screen method was shorter than that of the QR-Tracking method (71.0 ± 23.9 s vs. 98.4 ± 59.5 s, p = 0.042).
    Conclusion: The accuracies of out-of-plane needle placements using the 3D AR protractor with the two registration methods were equally high, with short procedure times. In clinical use, the Fix-On-Screen registration method would be more convenient because no additional markers are required.
