2025
Position a human patient with internal carotid stenosis, a condition characterized by narrowing of the internal carotid artery, on the imaging table for digital subtraction angiography (DSA). Insert an angiocatheter into the common carotid artery at the fourth cervical vertebra level. Capture a pre-contrast X-ray image to record background structures like bones and soft tissues using X-ray irradiation. Administer an iodine-based contrast medium into the carotid artery. The contrast medium...

Calcified Artery Preparation and Processing with Preserved Morphology and RNA for Digital Spatial Profiling
0 Views •
2026
This protocol includes a step-by-step workflow for calcified vascular specimens: tissue handling, decalcification, RNA validation, calcification level detection, and region-of-interest selection strategies on the Nanostring GeoMx Digital Spatial Profiler (DSP). The goal is to present a comprehensive method for preserving vascular tissue morphology and RNA for reliable spatial transcriptomic analysis.

Blood pressure monitoring is one of the essential vital signs, and for a majority of patients, measuring it utilizing non-invasive techniques provides accurate values. However, there are situations in which the blood pressure requires more exact, specific, and reliable measurements.

Surgical correction of ALCAPA is highly recommended, regardless of age or the degree of intercoronary collateralization. This protocol presents a technique for the direct re-implantation of adult-type ALCAPA into the aorta to re-establish the dual-coronary perfusion. Whenever feasible, direct re-implantation is preferred to other surgical correction techniques.

Passive mechanical testing of mouse carotid arteries is described, with special consideration for adapting to different specimen ages. The procedures include determining the in vivo length of the artery, mounting it in a pressure myograph, recording data, measuring the unloaded dimensions and analyzing the resulting data.
FAQs
Branches arising mainly from the radial and ulnar arteries extend along the digits and form interconnected vascular networks. These networks divide into progressively smaller vessels, allowing blood to reach different regions rather than remaining confined to one channel. Their arrangement supports continuous delivery across the length of each digit and helps maintain perfusion when local vascular pathways vary.
Digital arteries ultimately supply smaller vessels and capillaries, where oxygen and nutrients diffuse from the blood into surrounding tissues. This exchange connects arterial circulation with the metabolic needs of skin, muscle, and other digit tissues. Without effective delivery to the capillary level, circulation may not adequately support tissue metabolism, sensation, or movement.
Circulation in the digits contributes to more than nutrient delivery. By supplying tissues involved in sensation and movement, it helps sustain their normal biological activity, while local blood flow also participates in temperature regulation. Consequently, changes in digital circulation can affect several functions at once rather than producing an isolated vascular finding.
Reduced digital blood flow may reflect arterial disease, trauma, or compression. Because these vessels serve the fingers and toes, impaired circulation can provide a localized sign of broader vascular or mechanical problems. Identifying reduced perfusion is therefore relevant to clinical assessment, especially when determining whether tissue function or recovery may be threatened.
Clinicians can assess digital pulses and perfusion as indicators of blood delivery to the fingers or toes. These observations contribute to evaluating peripheral vascular function and may help guide diagnosis when arterial disease, trauma, or compression is suspected. The findings are also relevant when monitoring circulation in tissues affected by injury or treatment.
Their small caliber and organized distribution along the digits make digital arteries relevant to reconstructive microsurgery. Understanding their branching networks helps clinicians account for the blood supply of tissue involved in reconstruction. Assessment of digital perfusion can also support decisions about whether circulation has been preserved or compromised after an injury or procedure.
Digital arteries provide a focused system for studying peripheral vascular function because their circulation can be related directly to tissue metabolism, sensation, movement, and temperature regulation. Researchers can examine digital pulses and perfusion to investigate changes in blood flow. This makes the digits useful for connecting vascular observations with localized tissue function.
