Summary
Internal iliac artery occlusion is necessary for some abdominal aneurysm repairs. An anchor balloon technique helps advance the necessary device through challenging iliac arteries for Amplatzer vascular plug placement.
Area of Science:
- Vascular surgery
- Interventional radiology
- Medical device technology
Background:
- Internal iliac artery (IIA) occlusion is a critical step before certain abdominal endovascular aneurysm repair (EVAR) procedures.
- The Amplatzer vascular plug (AVP) is effective for IIA occlusion but necessitates a large-bore catheter or guiding sheath.
- Navigating tortuous or angulated iliac arteries presents a significant challenge for deploying the AVP.
Observation:
- Standard techniques for advancing large-bore catheters/sheaths can be difficult in complex iliac anatomy.
- A novel anchor balloon technique was developed to facilitate sheath/catheter advancement.
- This technique aims to improve the feasibility of AVP placement in challenging cases.
Findings:
- The proposed anchor balloon technique enables smoother advancement of guiding sheaths/catheters through tortuous iliac arteries.
- This method overcomes anatomical challenges previously limiting AVP deployment.
- Successful delivery of the AVP for IIA occlusion is facilitated by the anchor balloon technique.
Implications:
- The anchor balloon technique offers a potential solution for challenging AVP placements in EVAR.
- This approach may expand the applicability of endovascular repair in patients with complex iliac anatomy.
- Improved procedural success rates and patient outcomes are anticipated with this innovative technique.

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

When two or more physical quantities are linked by a single relationship, a change in one variable necessarily affects the others. This interdependence forms the basis of related rates analysis, which examines how different quantities change with respect to time. A classic physical example is an expanding balloon, where the size of the balloon changes continuously as air is added.For a hot air balloon, the inflated envelope is commonly idealized as a perfect sphere to simplify mathematical...

A drone flying through complex terrain often relies on more than one sensing method to estimate small changes in altitude. Along with direct measurements, air pressure provides a useful indirect indicator of vertical movement. Atmospheric pressure decreases as altitude increases, and this relationship is commonly described using an exponential model. Although accurate, converting pressure measurements into altitude values requires calculations that are too complex to perform repeatedly during...

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...
