Artery Vs Vein Color
Different vessels: The vein system in your legs is divided into two systems: deep and superficial. The deep vein system travels within the muscle compartment of your leg. The profunda femoral vein is a deep vein. The superficial vein system flows closer to the skin surface-above the muscles. The great saphenous vein is superficial. The superficial system flows into the deep system, which flows up into the body. ...Read more
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
Yes and No: Coronary artery bypass requires some form of conduit for bypass. Superficial veins from the lower limbs have been used for bypass. Smaller arteries from the underside of the chest wall have been used in favor of veins for the left side of the heart. Early enlarged varicose veins can still be used for bypass; however more advanced wall bulges and wall aneurysms Prohibit use of the varicosed veins. ...Read moreSee 3 more doctor answers
If doppler arterial ultrasound says ulnar artery is supplying flow and collateral flow is good . What is embolism with branch occlusion.
I will try again: There are several cause of arterial occlusions. There are degrees of arterial blockage. If a clot moves- embolize s it can obstruct multiple vessels and branches causing more tissue to be under circulated-ischemic. The remaining question is why the radial clotted: embolus, trauma, needle sticks, thoracic outlet and aneurysm. Need exam. Doppler helps define the location but not the cause. ...Read more
MRI vertebrobasilar hypoplasia right side theres robust flow void anastomosing the basilar artery w cavernous portion of internal carotid artery/mean?
Normal variant: The arteries at the base of the brain can course in several different patterns but ultimately get the job done, that is, supply brain tissue. Your pattern is like your fingerprint. Some more unusual patterns have an increased association with aneurysms, but this would have likely been described if present and vertebro basilar hypoplasia, as in the picture, is pretty common. ...Read more
Depends on cause: Patients can present emergently with sudden onset of right upper quadrant pain, nausea, and/or fever. However, most commonly the symptoms of the primary infectious and inflammatory condition that led to portal vein obstruction predominate. For example, pain related to pancreatitis. In the chronic phase, patients most often present with complications related to bleeding from enlarged veins in belly. ...Read more
What is the difference between unilateral superficial vein swelling and collateral superficial vein swelling?
Difference?: Unilateral vein swelling would be dilated veins in one area compared no non dilated veins in the opposite area (i.e. R leg and L leg). Collateral veins usually form around a blockage such as a DVT. In actuality, there may not be any difference between the two. ...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?
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 moreSee 1 more doctor answer
Chronic radial artery occlusion. Pain in hand arterial doppler shows interosseos artery enlarged. Ulnar artery responsbile for profusion. Advice?
Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?
Diagnosed with total right radial artery occlusion with collateral flow in ulnar and intraosseous artery. Occlusion due thrombus. What does this mean?
Clot in your artery: A blood clot in your artery can occlude the blood flow to your hand, fortunately there are other arteries that can compensate for this. Unless you had trauma to that arm , you should see a hematologist or internal medicine doctor to be worked up to rule out a hypercoagulable condition. You should disclose this to your surgeon if you need surgery in the future ...Read more
Very different: Varicose veins are defective veins that have weakened walls. Blood clots can form in varicose veins, a condition known as "thrombophlebitis, " but the majority of varicose veins do not have blood clots. Blood clots can also form in the deep veins, a condition known as dvt. This is a serious condition occurs more commonly after surgery, trauma, long plane/car rides, during pregnancy, among others. ...Read moreSee 3 more doctor answers
Can, partially occlusive chronic thrombosis of lef saphenous in the calf and small saphenous vein proximal and mid calf, cause deep vein thrombosis?
Basilar artery: Basilar artery is formed by the confluence of the vertebral arteries. Vertebral arteries are branches off the subclavian arteries. They supply the posterior aspect of brain and flow into the circle of willis. Vertebral occlusions can occur due to atherosclerotic disease and dissection from trauma. ...Read more
Pv: We usually use portal vein embolization to preferentially grow a segment of liver that we choose while shrinking a segment of liver we want to get rid of. For instance, if we want to respect part of the liver we can first get the remaing liver to hypertrophy by embolizing the vein that feeds the segment that's coming out ...Read moreSee 1 more doctor answer
