Patients treated in this fashion have an existing fistula with symptomatic venous hypertension or good fistula options but complete central vein obstruction, a patent subclavian/axillary vein to the costoclavicular junction, and no other options in the contralateral arm.
We therefore found that such epiphora creates greater discomfort than partial obstruction or patent lacrimal systems.
Ultrasonography showed the left common iliac artery obstruction and patent femoral, popliteal and tibial arteries.
It was well established that once UAO in patients with OSA occurs, it requires much higher inspiratory pressure to open the collapsed airway and the end-expiratory pressure requirement to maintain the airway patent is lower after the obstruction is overcome [ 27- 29].
In patients with patent cystic ducts, the distance from obstruction to the cystic duct takeoff was classified as either greater or less than 1 cm.
The nostril that was more patent and did not have nasal obstruction or septal deviation was chosen for NGT insertion.
Failure of endoscopic third ventriculocisternostomy (ETV) can be defined as primary (failure to achieve an efficient stoma) or secondary (obstruction of a previously patent stoma).
Frequently, one of the ends of the tube is patent, leading to decompression of the tubal obstruction with discharge and consequent shrinkage of the pelvic mass, resulting in a temporary resolution of symptoms, as described in the clinical presentation.
Empty nose syndrome (ENS) is an iatrogenic disorder most often recognized by the presence of paradoxical nasal obstruction despite an objectively wide, patent nasal fossa.
Two thirds of the remaining eligible patients (28 of 45) had obstructions less than 1 cm from patent hepatocystic junctions.
A cricothyrotomy is an incision made through the skin and cricothyroid membrane to establish a patent airway during certain life-threatening situations, such as airway obstruction by a foreign body, angioedema, or massive facial trauma.
