Patients with a primary diagnosis of type A aortic dissection between 2016 and 2019 who underwent open surgery were first identified (ICD-10 code: I71.0, I71.01, I71.02, and I71.03), which consisted of our initial study group (index group). Patients who successfully underwent surgery and were...
AD case was identified by the presence of any of the following ICD codes: “441.0” (ICD-9) or “I71.0” (ICD-10), or medical terms in Chinese including aortic dissection (or rupture). To minimize the possibility of missing patients, we firstly constructed a relatively loose algorithm to...
Aortic DissectionDisparitiesBackground: Aortic dissection (AD) and aneurysm (AA) have a low incidence but are severe health risks associated with high mortality rates, and based on location, can have a mortality rate of over 80%. We aim to highlight disparities in mortality based on gender, ...

Malvindi and associates (2015) stated that aortic valve-sparing operation has been progressively widely performed for the treatment of aortic root aneurysm. Nowadays, this procedure has been proposed even in presence of a BAV, severe aortic regurgitation or in primary aortic dissection repair. These...

dissections of the ascending (Stanford type A) or descending (Stanford type B) thoracic aorta are life-threatening conditions requiring emergency treatment, often including surgical repair, and are associated with high short-term and long-term mortality risk1,2. Despite the lethality of these condit...

In fact, the major advances that have lowered the mortality of aortic surgery, namely, minimal dissection and elimination of resection of the aorta, occurred in the 1960s and 1970s. While the use of epidural catheters for pain management has enhanced aortic surgery, it probably has not ...
