Limited intimal tear

Evidence of intimal tear in type A intramural hematoma of the aorta: A case series☆

INTRODUCTION Aortic intramural hematoma (IMH) is described as "dissection without intimal tear" due to rupture of vasa vasorum, which results in bleeding within the tunica media in the absence of intimal disruption or blood flow communication. The aim of our study is to validate perioperative evidence of intimal entry tear in patients with IMH and to suggest that this entity may represent a par...

Virtual angioscopy finds the intimal tear of an acute thoracic aortic dissection.

Intimal tear without hematoma: an important variant of aortic dissection that can elude current imaging techniques.

BACKGROUND The modern imaging techniques of transesophageal echocardiography, CT, and MRI are reported to have up to 100% sensitivity in detecting the classic class of aortic dissection; however, anecdotal reports of patient deaths from a missed diagnosis of subtle classes of variants are increasingly being noted. METHODS AND RESULTS In a series of 181 consecutive patients who had ascending o...

Confirmation of Intimal Tear in Thrombosed-Type Acute Aortic Dissection by Virtual Angioscopy

INTRODUCTION Therapeutic strategies for intramural hematoma (IMH) involving the ascending aorta remain controversial. REPORT The patient was a 72 year old woman with a history of chest pain. Multidetector computed tomography (MDCT) showed an IMH involving the ascending aorta. Because virtual angioscopy revealed a punctate intimal tear in the ascending aorta, acute aortic dissection with an in...

Correlation between the layer of an intimal tear and the progression of aortic dissection.

Thoracic aortas isolated from dogs were evaluated to determine the correlation between the depth of an intimal tear and the progression of aortic dissection. Thoracic aortas obtained from 99 adult mongrel dogs were used. An intimal tear (aortic pocket) was created on the aortic wall and the aorta was connected in series to a closed circuit (150 mmHg/100 mmHg and 60 beats/min). The progression o...
