Percutaneous Cricothyrotomy

Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA A surgical airway procedure is indicated when other forms of endotracheal intubation have failed and ventilation is worsening or not possible. This is the feared "can't intubate, can't ventilate" scenario, and in the emergency setting, cricothyrotomy is the surgical procedure of choice. Cricothyrotomy is preferred over tracheotomy because of the lower risk of complications, the predictable anatomy...

2015
We present a protocol to assess changes in neuromuscular function. Percutaneous electrical nerve stimulation is a non-invasive method that evokes muscular responses. Electrophysiological and mechanical properties of these responses permit the evaluation of neuromuscular function from brain to muscle (supra-spinal, spinal and peripheral levels).

In this manuscript, we describe percutaneous isolated hepatic perfusion with simultaneous chemofiltration as treatment for unresectable liver metastases. This procedure is performed under general anaesthesia in the angiosuite by an experienced team, consisting of an interventional radiologist, a clinical perfusionist and anaesthesiologist.

The accompanying video describes a procedure for percutaneous placement of the WATCHMAN Left Atrial Appendage (LAA) Device. The WATCHMAN is a nitinol device designed to be permanently implanted at, or slightly distal to, the opening of the left atrial appendage (LAA) to trap blood clots before they exit the LAA, preventing thromboembolic stroke.
FAQs
Imaging helps clinicians navigate the catheter to the intended opening, defect, or access site and confirm placement of the closure device or delivery system. This guidance supports accurate targeting before deployment and helps match the intervention to the relevant anatomy. In medicine, imaging is therefore central to the technique’s precision rather than merely an optional procedural aid.
The closure mechanism depends on the clinical target and the tissue or vessel being treated. Mechanical expansion places a device that blocks or supports the site, suturing joins or reinforces tissue, and occlusive material obstructs blood flow through a selected opening or vessel. These approaches provide different ways to seal a defect, reinforce tissue, or prevent continued flow.
Appropriateness depends on the type of opening, defect, patent vessel, or vascular access site being addressed and on the closure goal. Clinicians select a device or delivery approach that can block blood flow or reinforce tissue at that location. This target-specific planning explains why the technique can be applied across both interventional cardiology and vascular medicine.
Percutaneous closure can reduce the need for open surgery by reaching the treatment site through a catheter inserted through the skin. The approach may limit tissue trauma and incision size while allowing precise placement of a closure device or delivery system. These features can support shorter recovery, making it useful when the clinical target is suitable for catheter-based treatment.
Clinicians first access the body through the skin, then advance a catheter toward the selected site under imaging guidance. A closure device or delivery system is positioned at the opening, defect, vessel, or access site, followed by deployment of the chosen mechanism. The intervention is intended to block blood flow or reinforce tissue without requiring open surgical access.
The technique is used for selected septal defects, patent vessels, and vascular access sites. In interventional cardiology, the target may involve a septal defect or patent vessel, while vascular medicine may focus on a vessel or an access site requiring closure. The specific application depends on whether treatment must obstruct flow, seal an opening, or reinforce tissue.
Potential outcomes include a smaller incision, less tissue trauma, shorter recovery, and more precise treatment. These advantages arise from delivering the closure system through a catheter rather than using open surgical access. The approach is especially relevant when clinicians can accurately reach and treat the selected site while achieving the intended blockage of blood flow or tissue reinforcement.
