Chronic Thoracic Aortic Dissection: How to Treat, When to …
The main purpose of TEVAR in chronic dissection is to eliminate aortic expansion in the chronic phase of a previous acute type A, type B, or non-A-non-B aortic dissection. Favorable results include true lumen expansion, false lumen thrombosis or shrinkage, and stable or diminishing aortic diameter, generally stated as positive aortic remodeling.
Imaging and Surveillance of Chronic Aortic Dissection: A …
2022年2月17日 · Imaging plays a central role in the medical decision-making of patients with chronic aortic dissection. Accurate aortic diameter measurements and rigorous, systematic documentation of diameter changes over time with different imaging equipment and modalities pose a range of practical challenges in these complex patients.
Conservative Management of Chronic Aortic Dissection with …
A chronic aortic dissection tends to be associated with complications which weaken the aortic wall. Degeneration of the aortic vessel can eventually lead to the rupture of the aorta. Another important complication of a chronic dissection is the gradual impairment of distal perfusion which can eventually lead to ischemic syndromes
CR is a 62 Y male patient with hx of afib (previously on eliqius), HTN, who presented to Stanford from OSH due to concern for Type B dissection. Managed in ICU for blood pressure control, placed on clevidipine drip. In the ICU, he started complaining of intermittent numbness and tingling in his right leg.
Aortic dissection - EMCrit Project
2024年9月28日 · Classification of aortic dissection based on time after symptoms: Acute aortic dissection: <2 weeks. Subacute aortic dissection: 2 weeks – 3 months. Chronic aortic dissection: > 3 months. (American guidelines utilize six weeks as a cutoff between subacute and chronic dissection, whereas European guidelines use 90 days). (Vincent 2024)
Endovascular Repair of Chronic Descending Dissection
2024年12月25日 · Endovascular repair has become a key approach for managing chronic type B aortic dissection, improving outcomes and reducing mortality through advanced techniques and tailored hybrid strategies. The evolving landscape of chronic TBAD management emphasizes the increasing importance of TEVAR.
Management of chronic type B aortic dissection - Vessel Plus
In this manuscript, we will focus on chronic aortic dissections that involve the aorta distal to the left subclavian artery (type B). In the past, open surgical management was the treatment of choice when intervention was required for chronic type B aortic dissections (CTBAD).
False lumen hemodynamics and partial thrombosis in chronic aortic ...
2024年1月6日 · Partial thrombosis of the false lumen (FL) in patients with chronic aortic dissection (AD) of the descending aorta has been associated with poor outcomes. Meanwhile, the fluid dynamic and biomechanical characteristics associated with partial thrombosis remain to …
Chronic thoracoabdominal aortic dissection: endovascular …
2021年9月2日 · Persistent false lumen patency in chronic thoracoabdominal aortic dissections after thoracic endovascular aortic repair (TEVAR) contributes to negative aortic remodeling. We have previously described the evolution of various endovascular techniques to treat persistent false lumen perfusion including false lumen embolization.
False lumen hemodynamics and partial thrombosis in chronic aortic ...
Key points: • Partial false lumen thrombosis has been associated with aortic growth in patients with chronic descending aortic dissection; therefore, the identification of prothrombotic flow conditions is desirable. • The presence of partial false lumen thrombosis as well as its extent was related with false lumen kinetic energy.
