Summary
A rare complication during cardiac catheterization involving radial artery spasm and anatomical variation led to catheter entrapment. Successful management included coil embolization for artery avulsion.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Anatomy
Background:
- Severe aortic stenosis necessitates intervention, often preceded by diagnostic coronary angiography.
- The transradial approach is a common method for cardiac catheterization.
- Radial artery anatomical variations can pose challenges during vascular procedures.
Observation:
- Catheter entrapment occurred during coronary angiography due to radial artery spasm.
- An arteriogram revealed a high take-off anatomical variation of the radial artery.
- Attempts to dislodge the catheter led to radial artery avulsion.
Findings:
- Successful management of radial artery avulsion was achieved using coil embolization.
- This specific complication (catheter entrapment secondary to spasm and anatomical variation) has not been previously reported.
Implications:
- Highlights the importance of recognizing potential radial artery anatomical variations during transradial procedures.
- Suggests the need for careful catheter manipulation in cases of radial artery spasm.
- Emphasizes coil embolization as an effective treatment for radial artery avulsion in this context.

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

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.

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

01:09Bones of the Upper Limb: Radius
9.0K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
