Final answer:
Surgery for type B dissection is generally reserved for patients with complications or persistent symptoms. Examples of conditions that would warrant scheduling surgery include rupture or impending rupture of the aorta, persistent pain despite medical therapy, and malperfusion syndrome. Other factors such as a large aneurysm or an unstable dissection may also be considered for surgery.
Step-by-step explanation:
In the case of a type B dissection, surgery is typically reserved for patients who have complications or symptoms that require intervention. Some examples of conditions that would warrant scheduling surgery include:
- Rupture or impending rupture of the aorta
- Persistent pain despite medical therapy
- Malperfusion syndrome, which refers to inadequate blood flow to organs or limbs
Surgery may also be considered for patients who have a large aneurysm in the descending aorta, or those with an unstable dissection that is not responding to medical management.
