Conservative treatment of type A aortic dissection: a case report with 5 years of follow-up.

Background: Acute aortic dissection causes major morbidities and mortalities. The treatment of choice for type A aortic dissection (TAAD) is emergent surgical intervention. However, surgery per se may be associated with significant risk, in part due to the general surgical challenges, and the inherent hemodynamic- and organ malperfusion effects. In particular, surgery correlates with marked perioperative mortality in octo- and nonagenarians and those with severe comorbidities. Conservative medical treatment represents an alternative approach to patients for whom surgery is deemed high-risk, but case literature in this field remains sparse.

Case Description: We present a case of an 86-year-old female admitted with TAAD and deemed inoperable by the cardiothoracic surgical team due to excessive risks. The patient was treated conservatively with an extensive and aggressive antihypertensive regimen, leading to an uneventful recovery.

Conclusions: Most cases of TAADs require emergent surgery. However, surgery is often contraindicated in comorbid and older patients due to excessive risks. The patient in this report is unique due to the long follow-up after conservative treatment and the close adherence to treatment protocol due to continuous therapeutic monitoring. It is important to consider factors for and against conservative therapeutic strategies, and, importantly, adherence to such should be carefully monitored to optimize patient outcomes.
