aortic dissection begins with the formation of a tear in the aortic intima, and it directly exposes an underlying diseased medial layer to the driving force of the intraluminal blood. this blood penetrates the diseased medial layer and cleaves the media longitudinally, thereby dissecting the aortic wall. herein, we report the case of a 38-year-old woman, who presented with chest pain and dyspne...

abstract background: renal insufficiency is a potential complication after infrarenal abdominal aortic aneurysm repair and is a significant risk factor for postoperative mortality and morbidity. the aim of this study was to analyze the effect of this risk factor, before and during operation. methods: in this prospective study, between 2003 and 2006, 45 patients underwent repair of an infrarenal...

angiotensin-converting enzyme (ace) inhibitors appear to correct many of the abnormalities associated with the vascular dysfunction found in diabetic patients. in this respect, quinapril is a unique ace inhibitor with multiple protective effects. the present study was carried out to investigate the effect of intraperitoneal administration of quinapril on the aortic reactivity of streptozotocin ...

background: optimal timing and mode of treatment for patients with coarctation of the aorta ( coa ) remain controversial, particularly in children. surgery, balloon dilatation, and stent implantation have all proven effective in the treatment of moderate or severe obstruction. the aim of this study was to investigate the complications of coa stenting angioplasty in pediatric patients. methods: ...

over the last 50 years, significant progress has been made in the surgical repair of thoracoabdominal aortic aneurysms (taaa).   improvements in perioperative care and surgical techniques have resulted in reductions in complication and mortality rates. adjunctive use of distal aortic perfusion and cerebrospinal fluid drainage has been especially helpful, reducing the incidence of neurological d...

background: the p ulsatility index (pi) shows continuous blood flow to the end organs and is a significant factor believed to decrease in aortic coarctation. correction of this factor is of great importance in the treatment of stenotic lesions of the aorta. however, there are minimal data regarding the trend of changes in the pi after stent implantation. furthermore, the association between the...

Stanford type A acute aortic dissection (AAD) is a very rare complication, with potentially lethal consequences in pregnancy. In fact, pregnancy has been regularly associated with the possibility of aortic. dissection in almost half of young women. Herein, we present the case of a 38-year-old woman in her 37th week of pregnancy. The patient’s medical history was indicative of G4L2Ab1(4 gestaiti...

a ruptured sinus of valsalva aneurysm rarely accompanies the aortic and tricuspid valve endocarditis. a 36-year-old woman presented with low-threshold dyspnea on exertion and fever. transthoracic and transesophageal echocardiography showed a ruptured noncoronary sinus of valsalva aneurysm with large vegetations on the tricuspid and aortic valves, resulting in moderately severe tricuspid regurgi...
