Phrenic and external intercostal motor responses to inspiratory load were studied in anaesthetized rabbits and after bilateral vagotomy. Animals were ventilated with a phrenic nerve driven respirator set at different gains, i.e. volume to phrenic-signal ratio. Load was imposed by occluding the trachea at the end of expiration for the period of one breath. It was found that vagally mediated low ...

TOPIC: Disorders of the Mediastinum TYPE: Medical Student/Resident Case Reports INTRODUCTION: A schwannoma is a rare neurogenic tumor arising from cells that form nerve sheath. They make up quarter all tumors and are seen between 20 to 50 years age. typically have an asymptomatic presentation benign course, with malignant features in around 5% cases. We present case 74-year-old female incidenta...

The mechanisms of respiratory action of the intercostal muscles were studied by measuring the effect of external forces (F) applied to the ribs and by modeling the effect of F exerted by the intercostal muscles. In five dogs, with the airway occluded, cranial F were applied to individual rib pairs, from the 2nd to the 11th rib pair, and the change in airway opening pressure (Pao) was measured. ...

Intercostal artery laceration is an unusual complication following thoracentesis, and has been reported only in elderly patients. We report a case of a 78-year-old man who developed a massive hemothorax following thoracentesis. Post-thoracentesis radiograph revealed a substantial increase in pleural fluid, and emergency chest tube insertion identified the hemothorax. He underwent right thoracot...

Wereport a rare case of ruptured intercostal arteriovenous fistula in a patient with neurofibromatosis type 1. The patient presented with severe back pain. Angiography revealed ruptured intercostal arteriovenous fistulas. Successful coil embolization to occlude the fistulas and the aneurysm resulted in successful recovery of the patient.

Transdiaphragmatic intercostal hernia is uncommon and mostly related to blunt or penetrating trauma. We report three similar cases of cough-induced transdiaphragmatic intercostal hernia, highlighting the anatomic findings obtained with different imaging modalities (radiography, ultrasonography, CT, and magnetic resonance) in each of the cases.

Traumatic transdiaphragmatic intercostal hernia, defined as an acquired herniation of abdominal contents through disrupted intercostal muscles, is a rarely reported entity. We present the first reported case of a traumatic transdiaphragmatic intercostal hernia complicated by strangulation of the herniated visceral contents.Following blunt trauma, a 61-year old man developed a traumatic transdia...

Cough-induced intercostal hernias without any type of external trauma are very uncommon. There have been less than 10 cases documented in literature. This clinical report describes a 66-year-old male who developed an intercostal hernia induced by a severe cough due to bilateral pneumonia and a subsequent rib fracture. It took almost a full year to diagnose this patient's chest wall mass. Only a...
