Transposed Basilic Vein
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
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
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
Can, partially occlusive chronic thrombosis of lef saphenous in the calf and small saphenous vein proximal and mid calf, cause deep vein thrombosis?
Great saphenous: It is a superficial vein that runs longitudinally along the entire course of the leg from the medial groin to the medial ankle. It is positioned between the skin & the muscle (located in the fat layer) & is not visible from the surface. A defect in this vein (i.e. valve reflux) leads to the majority of cases of varicose veins. It is also removed for use in bypass grafts of the heart & legs. ...Read moreSee 1 more doctor answer
Can you tell me how hepatic portal vein anastomose with superior vena cava and inferior vena cava?
Normal anatomy?: The portal vein is majority blood supply to the liver. It carries nutrient-rich blood from the gut to the liver. After passing through the liver, blood leaves via the hepatic veins and enters the inferior vena cava. There is a procedure, called TIPS, which creates a direct shunt between the portal vein and hepatic vein. ...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

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
Both cause cyanosis: Both are congenital heart defects that cause cyanosis (less oxygen than normal in the arterial blood.) however that is the only similarity. In transposition of the great arteries, the primary problem is that the aorta arises from the right ventricle instead of the left ventricle. In t(total)apvr, the primary problem is that the pulmonary veins do not connect directly with the left atrium. ...Read more
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
Pain and swelling: The most common symptom of DVT is pain and the most common physical finding is swelling. However, not everyone has these. If you have unexplained swelling with or without calf or thigh pain then a venous ultrasound would be indicated to look for a dvt. Sometimes even a ct scan or mrv is necessary. The bottom line is, if DVT is considered, then proper testing is required. ...Read more
What does the aorta, superior vena cava, inferior vena cava, right and left atrium, left and right venticle, aortiv valve, mitral valve, do?
Heart disease: There is no room here for all that. Look up cardiac physiology online for the explanation. ...Read more
A blood clot: A DVT is a blood clot ( thrombus) which has formed in the deep vein of usually the leg. It may involve the lower, upper or entire leg. Less frequently it involves the upper extremity. The other kind of clotting is superficial phlebitis which occurs in the veins just under the skin. If either is suspected one should seek immediate medical attention. ...Read moreSee 3 more doctor answers
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
