artery

Identified arterial entity

Record the evidence supporting identification as a particular native artery, including anatomical variants and unresolved naming differences.

1. What anatomical name, laterality and arterial circuit identify this vessel? definition
2. Which imaging, operative observation or anatomical record establishes its continuity with the arterial circulation? provenance

Bounded segment and connections

Record proximal and distal landmarks, branch origins, supplied territories and documented anastomotic connections.

1. Which landmarks delimit this artery or segment, and which branch origins fall within it? boundary
2. Which downstream territories and alternative arterial connections are documented, and by what evidence? provenance

Local lumen dimensions

Record measured diameters or areas, their positions and the reference used for any reported narrowing or dilation.

1. What lumen diameter or area was measured, at which location, imaging plane and acquisition phase? measurement
2. If narrowing or dilation is reported, which reference segment and calculation convention were used? measurement

Arterial route and deformation

Record course, tortuosity, focal angulation and relationships to adjacent structures, distinguishing persistent anatomy from position-dependent observations.

1. Where does the artery bend, deviate or pass through a potentially constraining anatomical space? boundary
2. Do observed calibre or course changes depend on posture, movement or another recorded acquisition condition? measurement

Observed wall condition

Record wall thickening, plaque, calcification or suspected disruption as supported observations, with diagnostic interpretations separately attributed.

1. Which wall features are directly visible, where are they located and what method demonstrated them? provenance
2. What evidence supports or leaves unresolved a suspected separation, breach or other loss of wall integrity? measurement

Bounded arterial abnormality

Record each suspected or established lesion's longitudinal extent, branch involvement, interpretation and comparison with previous observations.

1. What are the lesion's proximal and distal limits, and does it involve branch origins or adjacent segments? boundary
2. What change is demonstrated by comparable observations, and what apparent change could reflect measurement differences? measurement

Observed arterial flow state

Record patency, flow direction, velocity or volume flow, waveform and available local pressure with method and time.

1. What evidence establishes patency or obstruction, and could absent detected flow reflect a limitation of the observation? measurement
2. What flow and pressure measurements are available, and under what rest, exertion or other physiological conditions were they acquired? measurement

Supported delivery assessment

Record the evidence connecting this artery's condition to downstream delivery, without assuming that visible patency establishes adequate tissue perfusion.

1. Which independent observations of downstream perfusion support an assessment of this artery's contribution to blood delivery? provenance
2. Which collateral routes are anatomically documented, and which have evidence of functional flow? measurement

Intervention site and current status

Locate previous repairs, access sites, anastomoses and implanted devices relative to native segments and branches.

1. Which procedures or devices have affected this artery, at what sites and on what dates? provenance
2. Where are the boundaries between native artery, repaired tissue, implanted device and any separate graft? boundary

Artery-specific action assessment

Record the clinical question, supporting arterial observations, missing evidence and responsible decision-maker for proposed monitoring, investigation or treatment.

1. What artery-specific uncertainty or documented change is the proposed action intended to resolve or address? action
2. Which anatomical, haemodynamic and clinical prerequisites must the responsible clinician establish before the proposed action can proceed? action
3. Which named assessment framework and evidence support the proposed follow-up or escalation? provenance
