Rationale: Traumatic pseudoaneurysm of the sinus of Valsalva (PSV) is a rare but life-threatening condition, often resulting from blunt chest trauma. Rapid progress and a high risk of rupture highlight the importance of prompt diagnosis and intervention. We present a case of a rare pseudoaneurysm linked to the right coronary sinus after blunt chest trauma.
Patient Concerns: A 54-year-old male presented with chest pain, loss of consciousness, and coma following a motorcycle accident. Initial management included invasive ventilation at a local hospital before transfer for specialized care.
Diagnoses: Computed tomography angiography and transthoracic echocardiography confirmed a blunt traumatic PSV, along with an 8th rib fracture, findings later corroborated during open thoracotomy.
Interventions: The pseudoaneurysm was surgically treated with an open thoracotomy, and the defect was sealed using a pericardial patch.
Outcomes: The patient experienced an uneventful recovery, with follow-up confirming the restoration of normal daily activities.
Lessons: Traumatic PSV, though rare, demands heightened clinical awareness in cases of blunt chest trauma. Noninvasive computed tomography angiography serves as a rapid and reliable diagnostic tool. Early surgical intervention remains the definitive treatment to prevent catastrophic outcomes.

Background: Pulmonary contusions (PC) are common after blunt chest trauma and can be identified with computed tomography (CT). Complex scoring systems for grading PC exist, however recent scoring systems rely on computer-generated algorithms that are not readily available at all hospitals. We developed a scoring system for grading PC to predict the need for prolonged mechanical ventilation and initial hospital admission location.

: A 65-year-old male veteran presented to the Veterans Affairs Boston Healthcare System (VABHS) emergency department with progressive fatigue, dyspnea on exertion, lightheadedness, and falls over the last month. New bilateral lower extremity numbness up to his knees developed in the week prior to admission and prompted him to seek care. Additional history included 2 episodes of transient loss of consciousness resulting in falls and a week of diarrhea, which had resolved.

Introduction: Blunt traumatic aortic injury (TAI) is a critical condition and a leading cause of mortality in trauma patients, often resulting from high-speed accidents. Thoracic endovascular aortic repair (TEVAR) has developed into the preferred therapeutic approach due to its minimally invasive nature and promising outcomes. This study evaluates the safety and efficacy of TEVAR for managing TAI over a 10-year period at a Level-1 trauma center.

Background: Flail chest (FC) injuries are segmental osseous injuries of the thorax that typically result from high-energy blunt trauma and regularly occur in multiple trauma (MT) patients. FC injuries are associated with paradoxical chest wall movements and, thus, have a high risk of respiratory insufficiency or even death. An increasing number of studies recommend an early surgical stabilization of FC injuries, but a definite trigger that would indicate surgery has, thus far, not been identified.
