Term
| Upper Arterial Eval. Indications |
|
Definition
| Arterial Insufficiency, Thoracic Outlet Syndrome, Vasopastic Disorder Digital Ischemia, Abnormal vertebral artery waveform, Pre-op assessment for Hemodialysis & radial artery harvest for CABG. |
|
|
Term
| Upper Arterial Eval. Contraindications |
|
Definition
| No arm pressure measurement w/hemodialysis access. PVR & Doppler waveforms ok. |
|
|
Term
| Atherosclerotic Occlusive Disease |
|
Definition
| Mainly in the Subclavian & Innominate arteries. Rare in axillary, brachial, radial & ulnar. |
|
|
Term
| Upper Extremity Thromboemboli |
|
Definition
| Usually cardiac origin, or subclavian. Large emboli may occlude brachial artery. Small emboli blocks digit perfusion. |
|
|
Term
| Thrombo-angiitis Obliterans |
|
Definition
| AKA: Buerger's Disease. Inflammatory process that causes thrombosis of digital arteries. "Fixed" occlusive process. "Male" disease related to smoking. |
|
|
Term
| Episodic Digital Vasospasm |
|
Definition
| AKA: Raynaud's Syndrome. Affects fingers, toes & nose. White, blue then red. Pain & numbness. 40% connective tissue disorder,40% unknown,20% frostbite, vibration trauma. |
|

Definition
| Disease. Pure vasopastic disorder. |
|
|
Term
|
Definition
| Phenomenon. Vasospasm w/underlying disease; autoimmune, connective tissue. |

Term
|
Definition
| AKA: Takayasu's Arteritis. Inflammation of the lining of your arteries. |

Definition
Vascular Thoracic Outlet Giant Cell Arteritis Subclavian Artery Aneurysm |
|
|
Term
|
Definition
| Arm/hand weakness w/exercise. Reduced absent pulses. Hand numbness, weakness, pain position related. Ischemic fingers. Cold sensitivity. |
|
|
Term
| Upper Arterial Diagnostic Exam. |
|
Definition
| Segmentals (3 cuffs) Doppler @ Radial A. & Ulnar A., PVR, Doppler & Digit pressure from index finger. Difference ≥ 30mmHg between arm & forearm is brachial artery disease. |
|
|
Term
|
Definition
| Extrinsic compression of SCA or Axillary A. Intermittent compression of brachial plexus causing arm/hand pain, weakness & paresthesia. 95% neurogenic, < 5% vascular. |
|
|
Term
|
Definition
| R/O athero disease. TOS positions: Abducted 90°, 180° above head, pledge position head to hand/head away, stick-up position & symptomatic position. |
|
|
Term
|
Definition
| Vasospasm vs. small vessel disease. PPG & pressures for every digit. |
|
|
Term
|
Definition
| Baseline exam. Submerge in icy water 1-2 mins. Retest @ 2 min. intervals. Should return to baseline within 5 min., beyond 8-10 min. is vasospasm. |
|
|
Term
|
Definition
| If digit perfusion is reduced @ rest (low amplitude PVR,PPG), warm hand, if no improvement then fixed occlusive disease. |
|
|
Term
| Radial Artery Harvest Contraindications |
|
Definition
| Ischemic Digits, digit vasospastic disorder, athero occlusive disease in arms & sclerotic or small radial artery. |
|
|
Term
| Color Duplex Eval. for Arterial UE |
|
Definition
| Done for: Thrombo-embolus, Arterial stenosis-occlusion, adjunct to segmental study. Hand & digit waveforms very vasoreactive & change rapidly. |
