Assessment of apical radial pulse

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Area of Science:

Endovascular neurosurgery
Cerebral aneurysm treatment
Medical device technology

Background:

The PulseRider (PR) is a novel neck-bridge stent designed for cerebral aneurysm treatment.
Unlike conventional stents, PR delivery avoids microcatheter introduction into daughter branches, reducing intraluminal metal.
Potential challenges include difficulties in deploying leaflets into daughter vessels, risking coil herniation.

Purpose of the Study:

To present technical issues encountered during PulseRider (PR) deployment.
To share practical solutions and techniques for optimizing PR placement.

Main Methods:

Retrospective analysis of 14 T-type PulseRider (PR) procedures performed between August 2021 and June 2023.
Documentation and categorization of four specific technical challenges and their corresponding solutions ('technical options').

Main Results:

Successful PR placement was achieved in all 14 cases.
Fifty percent (7 cases) required technique modifications due to suboptimal leaflet unfolding.
Specific techniques were detailed for daughter artery transposition, leaflet angle correction, and neck protection.

Conclusions:

Addressing PR leaflet apposition requires consideration of various technical options.
These presented technical options can enhance the safety and efficacy of PulseRider deployment for aneurysm treatment.
