AI Article Synopsis

  • The text discusses a case of a 62-year-old male who experienced shunt catheter migration into the thoracic cavity after undergoing ventriculoperitoneal shunting (VPS) for hydrocephalus.
  • Despite VPS being a common treatment for hydrocephalus, this case highlights a rare complication where the catheter migrated through the intercostal space between the first and second ribs into the thoracic cavity.
  • The conclusion emphasizes the importance of proper subcutaneous tunneling over ribs and confirming catheter tip placement during the VPS procedure to prevent such complications.

Article Abstract

Background: Although ventriculoperitoneal shunting (VPS) is a universal treatment for hydrocephalus, it is generally well-known that the procedure often has complications. Shunt catheter migration is one such complication, but no reports of migration into the thoracic cavity are associated with the surgical technique. Herein, I present a case of thoracic cavity migration of a shunt catheter alongside anatomical pitfalls of the rib structure.

Case Description: The patient was a 62-year-old male diagnosed with subarachnoid hemorrhage due to craniocervical junction arteriovenous fistula and underwent direct surgery to occlude the fistula. We performed VPS for secondary hydrocephalus 1 month later. During VPS, the peritoneal catheter was tunneled subcutaneously over the clavicle to pass from the head to the abdomen. Several months later, the peritoneal catheter had migrated from the peritoneal cavity to the thoracic cavity. A computed tomography scan showed that the peritoneal catheter tunneled subcutaneously over the clavicle, penetrated the thoracic wall through the intercostal space between ribs 1 and 2, and entered the thoracic cavity.

Conclusion: When performing VPS, it is not enough to send the passer through the skin over the clavicle; it must also be tunneled subcutaneously over the ribs while confirming the position of the tip by touch.

Background: Hybrid emergency rooms (ERs) allow computed tomography (CT) scanning, interventional radiology, and surgery all in the same suite. Severe trauma patients with blunt thoracic aortic injury (BTAI) require rapid diagnosis and treatment. Hybrid ERs allow the potential for clinicians to implement multiple therapeutic procedures, including thoracic endovascular aortic repair (TEVAR), for these types of conditions without the need to transport the patients.

Background: Chylous ascites is an uncommon condition, occurring in less than 1% of ascites cases. It results from traumatic or obstructive disruption of the lymphatic system, causing the leakage of thoracic or intestinal lymph into the abdominal cavity. This leads to the accumulation of a milky, triglyceride-rich fluid.

Pneumopericardium (PPC) is defined by the presence of gas in the pericardial cavity, often leading to cardiac tamponade and a high mortality rate. This report describes a case involving a 33-year-old man found deceased a few meters from a knife, his clothes intact, with no resuscitation attempt made. A knotted scarf was tightly fastened around his neck, without ligature mark.

Introduction: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is commonly used for diagnosing mediastinal lymphadenopathy. Despite a low complication rate, severe hemorrhage can occur which is reported in this literature, particularly in hypervascular conditions like Castleman disease.

Methods: A 54-year-old male with idiopathic multicentric Castleman disease underwent EBUS-TBNA for mediastinal lymph node sampling.

Rupture of the thyrocervical trunk aneurysm into the thoracic cavity does not occur very often. It is an urgent condition due to hemorrhagic shock by massive hemothorax with potentially fatal consequences. Pregnancy and puerperium are additional risk factors for a rupture of the thyrocervical trunk aneurysm in patients with neurofibromatosis and aneurysms.
