The effect of breathing manner on inferior vena caval diameter.
AIMS Although the inspiratory 'collapse' of the inferior vena cava (IVC) has been used to signify normal central venous pressure, the effect of the manner of breathing IVC size is incompletely understood. As intra-abdominal pressure rises during descent of the diaphragm, we hypothesized that inspiration through diaphragmatic excursion may have a compressive effect on the IVC. METHODS AND RESU...
متن کاملModified Valsalva Maneuver vs. Standard Valsalva Maneuver on Emergency Department Patients Presenting with Supraventricular Tachycardia
Background: Supraventricular tachycardia (SVT) is a relatively common dysrhythmia among the general population and a common dysrhythmia presenting to the emergency department. Generally speaking, it is assumed the provider should attempt a vagal maneuver as first-line treatment for SVT, and the most common vagal maneuver used is the Valsalva. Current resources describing the method to perform t...
متن کاملInferior Vena Caval Ligation
PULMONARY embolism, which is usually a complication of venous thrombosis in the lower limbs, is responsible for approximately 3 per cent. of howpital deaths. It is a common cause of morbidity and mortality in various medical and surgical conditions. It is generally accepted that anticoagulant therapy has an important place as a prophylactic measure in venous thrombosis and, when efficient, redu...
متن کاملSuperior vena caval aneurysm.
Venous aneurysms arising from the mediastinal systemic veins are rare. There are only 27 reported cases of such aneurysms. Majority arise from the superior vena cava. We are reporting a saccular aneurysm of superior vena cava in a 58-year-old male. The chest radiogram suggested superior mediastinal mass and the computed tomogram was suggestive of aortic arch aneurysm. Aortography and venography...
متن کاملVena Caval Anomalies
Anomalous vena cavae can have significant implications for procedures on the right side of the heart. We report a rare anatomical configuration in a 44-year-old female, which to the best of our knowledge, is the first report of such an association. She had a bicuspid aortic valve in conjunction with a persistent left superior vena cava (PLSVC) draining into the coronary sinus, and a left-sided ...
