Advantages and Disadvantages of Bypass Surgery vs Stents

Advantages

Stents are inserted quickly (within 1-2 hours) and the patient only has to stay overnight.
The patient can resume normal activities within a week if stents are inserted.
In bypass surgery, fatty deposits are less likely to build up as bypass surgery uses veins. Veins have a larger lumen and therefore help blood flow more easily.
Bypass surgery is general anaesthetic (asleep).

Disadvantages

In bypass surgery, it takes 3 months to fully recover as it is open-heart surgery.
Fatty substances may build up in stents over the years (may depend on diet).
Inserting stents is local anaesthetic (awake).

Evaluation

Stents prop open narrowed arteries and allow the patient to resume usual activity within a week.
