BACKGROUND An aortic aneurysm is a local dilation of the aorta, which tends to expand and often results in a fatal rupture. Although larger aneurysms have a greater risk of rupture, some small aneurysms also rupture. Since the mechanism of aortic rupture is not well understood, clarification of the microstructure influencing the failure to rupture is important. Since aortic tissues are stretche...
Traumatic thoracic aortic rupture is a life-threatening condition; aortic isthmus is the most common site of rupture, but in rare cases traumatic injury can localize elsewhere, such as at aortic arch or at the level of the diaphragm. In the past few years, endovascular treatment of traumatic aortic injury became a safe procedure, with lower mortality and complication, if compared with open surg...
A Suggestion of New Integrated Prognostic Fa c tor for Aortic Aneurysm : Ta n gential Stress Index 1
aortic aneurysm is also increasing (1). Recent studies have shown that abdominal aortic aneurysms were detected in 4% of men and women between 65 and 80 years old and 11% of men aged 60 or over (2-5). An aortic aneurysm can be readily detected by measuring aortic diameter; dilatation of 50% or more than expected value, or that of the proximal segment, indicates its presence (6). However, the ru...
BACKGROUND Thoracic aortic rupture and aortopulmonary fistulation are rare conditions in horses. It mainly affects Friesian horses. Intrinsic differences in biomechanical properties of the aortic wall might predispose this breed. The biomechanical and biochemical properties of the thoracic aorta were characterized in warmblood horses, unaffected Friesian horses and Friesians with aortic rupture...
BACKGROUND In recent years, some experimental and clinical studies on transcatheter aortic valve implantation (TAVI) have been conducted. TAVI is indicated in patients with calcified pure or predominant aortic stenosis. The risk of this technique is still high. Aortic valved stent implantation above the coronary ostia might avoid blocking the coronary ostia. METHODS AND RESULTS Twenty healthy...
Surgical Indication for Chronic Aortic Dissection in Descending Thoracic and Thoracoabdominal Aorta.
BACKGROUND To address the lack of information about the size of ruptures associated with chronic dissection in the descending and thoracoabdominal aorta, we evaluated the natural history of this pathology. METHODS AND RESULTS We analyzed data from 571 patients (mean age, 69.4±11.6 years) with unrepaired chronic aortic dissection in the descending or thoracoabdominal aorta with a maximal aorti...
INTRODUCTION The rupture of infrarenal abdominal aortic aneurysm is a surgical emergency condition with a high rate of mortality before the patients arrive at hospital. The signs and symptoms of abdominal aortic aneurysm rupture into the retroperitoneal cavity are pulsatile mass, abdominal pain, hypotension and shock, but sometimes silent symptoms also hide a dangerous and life threatening cond...
The rupture of a thoracic aortic aneurysm is a life-threatening emergency. Conventional open surgical repair carries a high mortality and morbidity. We report an elderly patient who suffered from rupture of a proximal descending thoracic aortic aneurysm close to the aortic arch. A hybrid operation consisting of a right-to-left carotid bypass followed by endovascular repair of the descending tho...
BACKGROUND Aortic root rupture is a major concern with balloon-expandable transcatheter aortic valve replacement (TAVR). We sought to identify predictors of aortic root rupture during balloon-expandable TAVR by using multidetector computed tomography. METHODS AND RESULTS Thirty-one consecutive patients who experienced left ventricular outflow tract (LVOT)/annular/aortic contained/noncontained...
OBJECTIVE To review diseases of the aorta that commonly require management in the critical care unit. DATA SOURCES Articles and published reviews on aortic dissection, traumatic aortic rupture and aortic aneurysm. SUMMARY OF REVIEW The aorta is the largest arterial vessel of the body and disorders that can lead to rupture (e.g. aortic dissection, traumatic aortic rupture and aortic aneurysm...
