Av fistula, av graft, subclavian or femoral catheter, av shunt permanent or temporary, which is better?

AV fistula: Countless studies and decades of research have shown a clear advantage for patients who undergo hemodialysis through an av fistula. The second best is an av graft and all catheter-based modalities for hemodialysis are a distant third. ...Read more

Mild inflammatory stranding in mesenteric fat adj. to urinary bladder. Mild cirum. wall thickening of bladder. Bladder distended. Self cath 30 yrs. ?

I assume these are: CT findings. These mild changes are probably of no consequence, considering you have been using cath for so many years. These finding don't explain much. Depending on the severity of symptoms for which your doctor ordered these scans, your doctor might want to order further tests. ...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

My cardiac MRI showed persistent left sided superior vena cava drains into a dilated coronary sinus w/ mild dilation of the main pulmonary artery?

My cardiac MRI showed persistent left sided superior vena cava drains into a dilated coronary sinus w/ mild dilation of the main pulmonary artery?

Mostly a normal: Variant. Every fetus has one, but in most it involutes before birth. 0.3% of the general population has one. It is the most common variation of the thoracic venous system. Left svc draining into coronary sinus is expected 90% of the time. Discuss with your doctor the significance in your case of the mild dilation of the pulmonary artery. ...Read more

Sigmoid colon cancer removed surgically. After 10 days ultrasound impression is ' subacute small bowel intestinal obstruction and mild intraperitoneal free fluid collection. Is this common?

Sigmoid colon cancer removed surgically. After 10 days ultrasound impression is ' subacute small bowel intestinal obstruction and mild intraperitoneal free fluid collection. Is this common?

No, not common: Bowel obstruction can occur due to post op adhesions(uncommon) or tumor left behind(this will happen if the cancer was advanced/late stage. Your doctor will have to sort out which of these two possibilities apply to your case. ...Read more

CT SCAN ABD/PELVIS W/O CONTRAST:WHAT IT MEANS?BOWEL:ORAL CONTRAST IDENTIFIED IN SMALL AND LARGE BOWEL LOOPS.No intestinal abnormality,air or fluid.

CT interpretation: Are u sure you have not had any other contrast imaging study within a few days before this CT you mentioned? If not then the CT you had must have been with contrast. Never the less, it sound like you have had a normal result with contrast appropriately moving through the small bowel and colon. Good luck I hope you feel better ...Read more

Bth fallopian tube shw mild dilatation of d distal 3rd due 2 fimbrail adhesions with forced peritoneal spillage in keeping with bilateral patent tubes?

Infection: Mild dilation and fimbrail adhesions and forced peritoneal spillage all are evidence of tubal infection. This will put you at high risk for ectopic pregnancy. When you get pregnant you need to be watched closely. ...Read more

Interpret CT: mild thickening of distal sigmoid & rectal wall w/o adjacent fatty stranding. Loops of mild distended sm bowel w/o clear transition zone?

Diverticulosis: and possibly prior episode of diverticulitis could present this way. So too does infected segment or inflammation. The mild dilated small bowel in the current context is not as much of concern as the condition of the colon. Best discuss these findings with your doctor to put them into a good clinical picture. Good luck ...Read more

MRI =Mild" thickening of heart muscle not HOCM.Tortuous descending aorta. Aberrant right subclavian artery which courses posterior to the trachea. ??

Mild thickening's OK: See my comment to your previous post regarding the other findings (tortuous aorta, subclavian artery). The mild thickening of the heart muscle is common, and not necessarily from HCM. It could be the effects of long-standing hypertension. Keeping ur BP low with a -pril or a -sartan (Enalapril, Valsartan, etc.) could even reverse the thickening of the heart. Thanks 4 ur question on HealthTap, & GL! ...Read more

1.  Ct scan shows 30% stenosis in the proximal vessel, 30-50% stenosis in the mid-vessel in left anterior descending artery. What procedure is needed?

Depends.: Depends upon symptoms and any preceding tests you may have done. If you have no symptoms I am not sure you need anything other than aggressive risk reduction. Possibly could have a chemical stress test done. Should consult with your cardiologist. ...Read more

During coronary angioplasty how are catheters inserted into the femoral artery to the heart?

During coronary angioplasty how are catheters inserted into the femoral artery to the heart?

Depends: Depending on the arterial access , a single IV like catheter is placed called an arterial sheath. All catheters are fed thru the sheath using a j-shaped guide wire. Most sheaths are placed in the femoral artery others in the radial arteries. All arteries lead back to the heart in a retrograde fashion and the catheter is manipulated into the artery of intrest for repair with angioplaty and stent. ...Read more

Fusiform aneurysmal dilation 2 CM of proper hepatic artery in porta hepatis. Can someone explain this in plain English?

Weakening of artery: Fusiform refers to the shape (spindle-shaped, ie both facing walls) of the aneurysm, or a bulge in the artery. See medical-dictionary.thefreedictionary.com/fusiform+aneurysm for a diagram. The proper hepatic artery is the artery to the liver; it goes through an opening called the porta hepatis ("liver door") or transverse fissure.

38 wk pregnant, bilateral hydronephroses rt kidney7.5mm, 1.5cmlft kidney, bladder elongated, 2vessel cord 1umbilical artery. Complicated & surgery need?

Fetal hydronephrosis: Mild right, moderate left kidney. Presume normal amniotic fluid. Elongated bladder suggests baby, if male, may have urethral valves, or bladder reflux if of either sex. Should be able to proceed with pregnancy as normal. Suggest contact a pediatric urologist. Baby needs work-up after birth, ultrasound & VCUG (bladder xray). Start antibiotics (amoxicillin) & circ. If a boy. May need surgery later. ...Read more

Can a LCX para ostial occlusion be stented in addition to small diagonal branches ?

Can a LCX para ostial occlusion be stented in addition to small diagonal branches ?

LCX para ostial occlusion be stented: Yes, but depends very much on the skills of the cardiologist. The diagonal is not the issue as supplies blood to a relatively small muscle mass of the hear. On the other hand the CFX , which is occluded, has developed collateral circulation, therefore is a protected artery. Some cardiologists in cases the CFX is very close to the LM, would refer to a surgeon. Talk to the surgeon how Confident he feels about doing the procedure using stent vs surgery. I would prefer the later. The best have a second opinion. ...Read more
