It is safe, because it stays in the patients true lumen and does not go subintimal or perforate, and its effective on all types of lesions.
If the catheter enters the subintimal space, it creates a limited dissection plane making re-entry into the distal true lumen easier.
Following the balloon inflation on antegrade guidewire creating the subintimal connection, the retrograde guidewire was easily passed from the subintimal space to reach the proximal RCA true lumen under IVUS guidance and into the antegrade guiding catheter (Figure 3).
The "complicated" type B-AD cases were classified with two or more of the following clinical presentations: (1) Symptomatic visceral malperfusion; (2) lower limb ischemia; (3) multi-barreled AD; (4) great compression of the true lumen (true lumen <10%); (5) large primary entry tear (≥10 mm); (6) refractory hypertension; and (7) recurrent thoracic pain or pain with documented rapid aortic enlargement, interpreted to be impending rupture.
The redesigned Outback Elite Re-Entry Catheter enables faster and more precise re-entry into the true lumen in the most challenging cases, and represents the first ever re-entry device available in Japan.
Percutaneous extraluminal recanalization: Usefulness of false channel balloon dilation and Heparin administration before true lumen re-entry.
TEE helped in identifying the true lumen from false lumen, and for negotiating the guide wire through the true lumen (Figure 2).
Hemorrhage into the false lumen impinges on the true lumen and reduces blood flow to the myocardium.
The celiac trunk, superior mesenteric artery (SMA), and two right renal arteries were perfused from the true lumen, albeit through small channels of thrombus.
The RCCA originated from the false lumen of the dissection while all other major vessels arising from the arch and visceral vessels arising from the abdominal aorta were supplied by the true lumen (Figure).
The true lumen is contiguous with the nondissected portion of the aorta and is usually smaller and more opacified than the true lumen during the angiographic phase of imaging.
Distal flap was not stented since clear discrimination between false and true lumen could not be made and her chest pain recovered.
