The extension of false lumen
may cause a narrowing in the true lumen, and diminished renal blood flow may cause renal infarct.
Two different lumens, a true esophageal lumen and false lumen
separated by a mucosal bridge, can be frequently identified by endoscopy as in our patient.
The intimal flap in the main and right pulmonary arteries was depicted as a dark line separating the true and false lumen
(Figures 3(a) and 3(b)).
6 percent, and the false lumen
was partially or completely thrombosed in 70.
Diagnosis is rarely made during life as false lumen
tends to rupture resulting in cardiac tamponade and sudden death.
As to TEVAR for type B-AD, the discrimination of true and false lumen
and successful sealing of the primary intimal tear are the prerequisite, However, predictors of aortic remodeling of the aorta after TEVAR would affect the survival rate and the re-intervention rate.
A contrast-enhanced CT scan revealed an intimal flap in the celiac trunk and a mural thrombus (Figure 1A) extending to the splenic artery and proximal hepatic artery (Figure IB) and causing moderate to severe narrowing of the celiac artery (demonstrated by CT angiography) (Figure 2) as well as a thrombosed false lumen
, increased attenuation of the surrounding fat, and a segmental splenic infarction (Figure 1).
TEE helped in identifying the true lumen from false lumen
, and for negotiating the guide wire through the true lumen (Figure 2).
The use of Heparin after insertion of the sheath is very important to prevent false lumen
thrombosis (Lupattelli, Basile, & Sardanelli, 2005).
Coronary artery dissection results from separation of the layers of the arterial wall creating a false lumen
between the intima and media or media and adventitia.
Due to the risk of entering a false lumen
, surgical management was planned.
Spontaneous coronary artery dissection is defined as the haemorrhagic separation of the coronary artery media, with the creation of a false lumen
, in the absence of precipitating factors (1).
