Venous Vs Arterial Co2
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
Please advise what is the difference between peripheral arterial "insufficiency" vs. Peripheral arterial occlusive disease?
Synonyms: They're different names for the same condition. ...Read more
Result of venous duplex scan for dvt. Evidence of peroneal veins with partially occlusive non acute dvt. Evidence of recanalisation and both paired veins are patent and small due to the DVT present?
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
Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?
US and Doppler: Doppler ultrasound is used to determine if there is retrograde flow in valved vein segments, i.e. between the junction of a superficial vein and a deep vein,, 2) between valved segments within a deep vein (deep vein reflux), 3) between valved segments of superficial veins (segmental venous reflux). B mode US compression techniques look for dvt and distal augmentation to confirm flow upstream ...Read moreSee 1 more doctor answer
Yes: They are completely different. Venous disease is somewhat genetic, but if people lived long enough almost everyone would probably get venous disease at some point in their life. In fact 15% of the adult population has venous disease. Arterial disease, in contrast, is not as common in the general population. It occurs in smokers, diabetics, and in people with high blood pressure and cholesterol. ...Read moreSee 1 more doctor answer

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
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
Different outcome: Arterial thrombosis occurs when there is stoppage of blood flow in an artery due to arteriosclerosis or embolus. The part that is fed by the artery is injured by the lack of blood supply. Venous thrombosis comes on after there is stagnant flow, injury to the vein lining, and abnormalities in blood components. There is local pain, but rarely tissue injury. ...Read moreSee 1 more doctor answer
Significant: Chronic venous stasis (cvi) is a result of long standing venous insufficiency due to malfunctioning of the valves of either the superficial, deep or both systems of veins. Chronic arterial insufficiency is due to long standing decrease arterial blood flow into either the legs or arms. Venous problems cause leg swelling and discoloration while arterial problems cause pain and even gangrene. ...Read moreSee 2 more doctor answers
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
After doppler scan result varicose veins both lower limbs greater saphenous system due to incompetence of perforators of bilateral knee no thrombosis
180 degrees: Arterial thrombosis is stoppage of blood flow from the heart to different parts of the body. The result is tissue death: in arteries to the heart=heart attack; in arteries to the legs=gangrene. Venous thrombosis is within veins which return blood to the heart. It may be in deep veins which is a serious matter often requiring anticoagulation, and in superficial veins appearing red, painful. ...Read moreSee 1 more doctor answer
What conditions apart from chronic cerebrospinal venous insufficiency (ccsvi) require ijv angioplasty?
Few: Aside from ccsvi angioplasty of the central veins is most commonly done to relieve narrowings caused by previous intrumentation (central lines, dialysis access, pacemakers, etc). In the ijv it is usually done to restore or improve access for insertion of a central venous catheter of some sort. Tumors can also narrow the central veins to the point where dilation is needed. ...Read moreSee 1 more doctor answer
How does one differentiate between anomalous pulmonary venous return & transposition of great vessels?
TAPVR vs. TGA: The diagnosis of anomalous venous return (TAPVR) vs. transposition of the great vessels (TGA) is made in the newborn period. Simply put, the TAPVR baby usual presents 'pink' (no blueness) while the TGA baby will appear 'blue'. There are several variations of both TAPVR and TGA. The diagnosis can be accurately diagnosed by transthoracic ECHO and all are surgically operable with excellent results. ...Read more
How to differentiate between anomalous pulmonary venous return & transposition of great vessels as the underlying disease?
Ultrasound: Pediatric cardiologist use ultrasound (an echocardiogram) to identify the type of congenital heart defect. In anomalous pulmonary venous return, the pulmonary veins do not connect to the left atrium in a normal manner. In transposition of the great arteries, the aorta is connected to the right ventricle and the pulmonary artery is connected to the left ventricle (backwards). ...Read more
