Summary of "Endovascular balloon occlusion of the aorta is superior to resuscitative thoracotomy with aortic clamping in a porcine model of hemorrhagic shock."

Noncompressible torso hemorrhage is the leading cause of potentially preventable death on the modern battlefield. The objective of this study is to characterize resuscitative aortic balloon occlusion (BO) compared to thoracotomy with aortic clamping in a model of hemorrhagic shock.

Use of resuscitative endovascular balloon occlusion of the aorta in a highly lethal model of noncompressible torso hemorrhage.

Noncompressible torso hemorrhage is a leading cause of death in trauma, with many patients dying before definitive hemorrhage control. Resuscitative endovascular balloon occlusion of the aorta (REBOA)...

Fast track occlusion of aorta with atrial septal defect sizing balloon.

We describe the case of a 57-year old woman referred to our emergency service with ruptured abdominal aneurysm. We placed a 34 mm Amplatzer sizing balloon II into the suprarenal level of aorta to imme...

Resuscitative Thoracotomy: An Update.

Resuscitative thoracotomy is a heroic procedure that may offer the only survival hope for trauma patients in extremis. However, this operation has been the subject of much debate and its use, feasibil...

Successful Endovascular Management of Intraoperative Graft Limb Occlusion and Iliac Artery Rupture Occurred during Endovascular Abdominal Aortic Aneurysm Repair.

For high-risk patients, endovascular aortic aneurysm repair (EVAR) is a good option but may lead to serious complications, which should be addressed immediately. A 75-year-old man with a history of ab...

Occlusion of M1 segment after superficial temporal artery-middle cerebral artery bypass in a giant M1 aneurysm with Onyx-34 injected via a double-lumen balloon under balloon inflation.

A 29-year-old patient attended our institution for recurrent strokes related to a giant partially thrombosed M1 aneurysm. Superficial temporal artery-middle cerebral artery (STA-MCA) bypass and subseq...

Vienna Absolute Trial: Balloon Angioplasty Versus Stenting in the Superficial Femoral Artery

Minimal invasive treatment (called "endovascular") of the arteries of the lower limb remains problematic, because recurrent disease ("restenosis") frequently leads to recurrent symptoms. A...

Medical and Biotech [MESH] Definitions

Use of a balloon catheter to block the flow of blood through an artery or vein.

Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.

Endovascular procedure in which atheromatous plaque is excised by a cutting or rotating catheter. It differs from balloon and laser angioplasty procedures which enlarge vessels by dilation but frequently do not remove much plaque. If the plaque is removed by surgical excision under general anesthesia rather than by an endovascular procedure through a catheter, it is called ENDARTERECTOMY.

An abnormal balloon- or sac-like dilatation in the wall of the THORACIC AORTA. This proximal descending portion of aorta gives rise to the visceral and the parietal branches above the aortic hiatus at the diaphragm.

A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).
