| 1. | These fibers contribute to the maintenance of the patency of the sylvian aqueduct.
|
| 2. | Great care needs to be taken during the planning phase to maximize airway patency.
|
| 3. | Safety and patency of mechanical ( stapled ) bowel anastomoses has been widely studied.
|
| 4. | He described the Eustachian tube and the maneuver to test its patency ( openness ).
|
| 5. | LMWH can also be used to maintain the patency of cannulae and shunts in dialysis patients.
|
| 6. | Similarly, airway patency and venous return may be compromised by circumferential burns involving the neck.
|
| 7. | A silastic tube or stent may be employed along with probing to maintain tear duct patency.
|
| 8. | If left uncorrected, patency leads to pulmonary hypertension and possibly congestive heart failure and cardiac arrhythmias.
|
| 9. | These findings underscore the importance of maintaining chest tube patency in the early hours after cardiac surgery.
