Coronary stent dislodgement is a rare complication of percutaneous coronary intervention. We report a case of stent dislodgement in the ascending thoracic aorta. The stent was mechanically distorted in the left circumflex artery (LCX) while being delivered to the proximal LCX lesion. The balloon catheter was withdrawn, but the stent with the guide wire was remained in the ascending thoracic aor...

Helically cut thoracic aortic strips (from rats, rabbits, and guinea pigs) in a state of low to moderate tone and under the influence of alpha-receptor blockade relaxed in response to isoproterenol. Propranolol blocked these relaxations. Helically cut thoracic aortic strips from cats and abdominal aortic strips from rats, rabbits, and cats were not relaxed by isoproterenol. In addition, aortic ...

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment option for thoracic aorta aneurysms (TAA). Endovascular access is a challenge. We present a novel TEVAR technique in a patient with single kidney and a 6.4 cm TAA. Attempting to place a sheath through iliac arteries was unsuccessful. The decision to proceed to hybrid TEVAR was made. The protection of the solitary kidney was ac...

INTRODUCTION Current strategies for repair of descending thoracic aortic aneurysms consist of open repair with surgical graft replacement or thoracic endovascular aortic repair. We review and update our overall experience in aortic thoracic diseases and specifically analyzed our outcomes with thoracic endovascular aortic repair in patients with descending thoracic aortic aneurysms. METHODS Fr...

OBJECTIVES Reference values of aortic deformation during the cardiac cycle can be valuable for the pre-operative planning of thoracic endovascular aortic repair (TEVAR) and for facilitating computational fluid dynamics. This study aimed to quantify normal aortic extensibility (longitudinal extension) and distensibility (radial expansion), as well as pulsatile strain, in a group of 10 (>60 years...

An L-shaped incision combining an upper half mid-sternotomy and a left antero-lateral thoracotomy at the fourth intercostal space has been proposed by several authors for extensive aneurysms involving the aortic arch and the proximal thoracic descending aorta. This approach usually requires the division of the left internal thoracic artery at its mid position, thus making it unusable for corona...

The vast database of the Yale Center for Thoracic Aortic Disease--which includes information on 3000 patients with thoracic aortic aneurysm or dissection, with 9000 catalogued images and 9000 patient-years of follow-up--has, over the last decade, permitted multiple glimpses into the "playbook" of this virulent disease. Understanding the precise behavioral features of thoracic aortic aneurysm an...

Perivascular adipose tissue (PVAT) is implicated as a source of proatherogenic cytokines. Phenotypic differences in local PVAT depots may contribute to differences in disease susceptibility among arteries and even regions within an artery. It has been proposed that PVAT around the abdominal and thoracic aorta shares characteristics of white and brown adipose tissue (BAT), respectively; however,...

Thoracic aortic mobile thrombus is a rare and significant source of peripheral, visceral, as well as cerebral emboli. A 51-year-old female with a history of emergency left brachial artery embolectomy 5 months previously was referred to our unit for evaluation of a mobile thrombus in the descending thoracic aorta. We describe the successful primary treatment of a symptomatic mobile thrombus in t...

Rupture of the thoracic aorta is a rare but recognized complication following pregnancy. The common causes of thoracic aortic rupture in the peripartum period are trauma, dissecting aneurysms and saccular aneurysms secondary to systemic connective tissue disease. We report a case of non-traumatic spontaneous aortic rupture in a patient without trauma or systemic connective tissue disease 1 day ...
