Ultrasound guided location and removal of retained arterial cannula fragment

Ultrasound-guided cannula cricothyroidotomy.

1128 November 2012 W HEN difficulty with airway management is anticipated, standard guidelines recommend that the airway is secured in the awake patient.1 In the “cannot intubate, cannot ventilate” situation, surgical or cannula cricothyroidotomy is required.1 However, identification of the cricothyroid membrane by palpation is frequently inaccurate, even under elective conditions.2 Preoperativ...

Fluoroscopically guided removal of a retained sheared guidewire following failed endoscopic ultrasound-guided pancreatic duct drainage.

sheared guidewire following failed endoscopic ultrasound-guided pancreatic duct drainage A 50-year-old man with a retained sheared guidewire in the main pancreatic duct and pancreatic parenchyma was referred for recurrent pancreatitis. He had previously undergone a pancreaticoduodenectomy for pancreatic hemangioma and was experiencing recurrent pancreatitis due to pancreaticojejunostomy strictu...

Ultrasound-guided arterial puncture.

Arterial blood gas (ABG) analysis can yield information vital to the management of both acute and chronic disorders affecting gas exchange. In the setting of a restrictive ventilatory impairment due to chest-wall deformities (eg, scoliosis), hypercapnia indicates severe impairment and should prompt consideration of noninvasive ventilation.1 However, arterial puncture is often painful, particula...

Lens Fragment Removal from the Anterior Chamber Using Cannula Aspiration

before concluding the surgical procedure, these complications can be prevented. We describe a case in which a lenticular fragment is identified and describe a novel technique of using a cannula to remove the piece rather than the typical re-insertion of the irrigation/aspiration handpiece which can actually create turbulent flow and lead to loss of the fragment under the iris or in the ciliary ...
