Artery (Definition)

Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more

Is it possible that atherectomy open a totally occluded leg artery or just a leg artery that has narrowed considerably?

Is it possible that atherectomy open a totally occluded leg artery or just a leg artery that has narrowed considerably?

100% Vs : If totally occluded (100% blocked) and it's chronic it can't be opened. If it's 99% blocked and a guide wire can be placed across the blockage, it may be possible to open the artery using angioplasty or atherectomy. If the vessel can't be approached or is too tortuous or peripheral intervention, it may be possible to bypass it with open surgery. ...Read more

Arterial doppler indicates that brachial, ulnar and intraosseous artery are of low resistive pattern. S this normal. Radial artery occluded due to clot?

Arterial doppler indicates that brachial, ulnar and intraosseous artery are of low resistive pattern. S this normal. Radial artery occluded due to clot?

Unusual: A peripheral artery should have a high resistant pattern on doppler exam. A low resistance may suggest a connection with a vein, arterial venous (av) malformation or av fistula. An injury to the arm may have caused occlusion of the radial artery and also an av fistula. Luckily the ulnar artery is usually the main vessel supplying the hand. Further studies may be needed to define the anatomy. ...Read more

Habing sharp pain in middle finger and fourth finger. What is the cause. Which nerves affect these fingers. Radial artery occluded. Is this related?

Complex symptoms: Having undergone an angiogram there is obvious concern for the vascularity of the limb. While the radial artery occlusion will effect the blood supply to the hand, it does not usually cause a sharp pain but more of an ache. The palmar aspects of the middle finger and half of the ring finger are innervated by the median nerve (carpal tunnel nerve). See a hand surgeon for an evaluation of symptoms. ...Read more
