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...

Coronary flow reserve (CFR) is useful for assessment of myocardial oxygen demand and evaluation of cardiovascular risk. This study establishes a step-by-step transthoracic Doppler echocardiographic (TTDE) method for longitudinal monitoring of the changes in CFR, as measured from coronary artery in mice, under the experimental pressure overload of aortic banding.

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.

Intracoronary Acetylcholine Provocation Testing for Assessment of Coronary Vasomotor Disorders

Intracoronary acetylcholine testing has been established for the assessment of epicardial coronary spasm more than 30 years ago. Recently, the focus has shifted towards the microcirculation and it has been shown that microvascular spasm can be detected using ACH-testing. This article describes the ACH-test and its implementation in daily routine.
FAQs
Balloon inflation widens the obstructed segment, creating a channel for blood to pass through the coronary artery. A stent is often deployed afterward to support the treated vessel and help maintain patency, meaning continued openness. These components serve complementary roles: dilation addresses the immediate narrowing, while the stent helps preserve the resulting lumen after the balloon is removed.
Coronary angiography provides the visual guidance needed to identify the relevant coronary lesion and select the segment for treatment. It also offers a procedural check after intervention by showing whether blood flow has improved. Thus, angiography supports both the initial decision about where to intervene and the assessment of the immediate result, rather than serving only as an imaging step.
Long-term PCI outcomes depend partly on coordinated advances in stent design, intraprocedural imaging, and antiplatelet therapy. Stent improvements support vessel patency, imaging helps clinicians assess the treated area, and antiplatelet treatment contributes to safer care. Together, these developments have helped improve procedural safety and longer-term cardiovascular outcomes for patients undergoing intervention.
Restoring flow is clinically important because the coronary arteries supply the heart muscle. When coronary artery disease narrows or blocks these vessels, reducing the obstruction can improve blood delivery to the affected tissue. This is why PCI has a central role in treating coronary artery disease and is also used for some heart attacks, where management of flow is relevant.
During the procedure, clinicians advance a catheter through a blood vessel toward the coronary artery identified for treatment. Angiography guides lesion selection, after which balloon inflation widens the obstruction. When appropriate, clinicians deploy a stent to support the vessel, then use angiography to confirm improved blood flow. The sequence links navigation, lesion treatment, structural support, and outcome assessment.
Immediate procedural success is assessed by examining blood flow after the treated lesion has been addressed. Coronary angiography provides this confirmation, allowing clinicians to determine whether flow has improved in the targeted artery. This post-intervention assessment complements the mechanical treatment itself and gives the procedural team information about the result before concluding the intervention.
Clinicians may use PCI when coronary artery disease produces a narrowed or blocked coronary artery, and in some heart attacks. Its clinical purpose is to reopen the affected route for blood delivery to heart muscle. The decision is informed by coronary angiography, which helps identify the lesion and provides a basis for evaluating the result after treatment.
