A cardiac team is choosing a procedure for a patient with several severe blockages in the coronary arteries. The team recommends coronary bypass surgery.
The table compares two procedures.
| Procedure | Effect on blood flow | Recovery and possible problems |
|---|---|---|
| stent treatment | immediately widens one accessible narrowing | faster recovery; a blood clot may form in the stent |
| coronary bypass surgery | rapidly restores blood flow around several severe blockages | longer recovery after major surgery; risks include bleeding, infection, complications from anaesthesia and clot formation |
Give one feature in the table that supports the recommendation and one feature that the patient may regard as a drawback.
