what causes anterior infarction and how do you treat it?

---

what is it?
is it serious if possible?
An infarction (death of tissue due to decreased blood supply) of the anterior wall of the heart. Thats the part of the hearts wall that faces out. It is a heart attack in a specific place of the heart.  (+ info)

what is the definition of fetal origin of the right posterior cerebral artery?

---

i had an mri/mra last week due to some left peripheral vision loss and headaches. my doctor told everything looked normal but yet she was going to refer me to a neurologist. looking over the notes, this is one thing i'm having a hard time defining. i'm just wondering why she would send me if everything is normal. maybe i'm over reacting
sounds like she wants a second opinion, and fetal origin means you were born with it, and posterior cerebral artery is the large artey on the outside of your head,,, probably where your headaches are...go get the second opinion,, better safe than sorry..  (+ info)

Why don't doctors intervene when 70% stenosis is in the left anterior descending Artery(LAD)?

---

I have a 70% stenosis in my LAD artery but the doctors tell me that they hesitate to do anything when you have a single artery stenosis but they give me the option of me consenting to intervention. What gives? This opinion was given to me by the renowned Dr. Denton Cooley of the Texas Heart Institute.
A lesion does not become hemodynamically significant until it occludes greater than 70%. Poiseuille’s Equation, which states that flow is affected by the radius of the vessel, the length of the vessel, and the viscosity of the fluid, would make it seem as though even a small reduction in diameter would drastically affect the resistance of the blood flow. This would be the case if blood vessels in the body were a straight series of long tubes with no bifurcations. However the anatomical makeup of the vascular system is more complicated than that, and therefore the equation suffers from inaccuracy when applied. The low pressure vascular beds of distal tissues and the length of the rest of the vessel, coupled with any further collateral blood supply are other factors that would affect the significance of the stenosis. Large vessels bifurcate into arterioles, which further bifurcate into capillaries. This complex branching of the vessels makes the diameter of the larger carrying vessel less significant until a critical blockage is present. At < 70% diameter reduction, the blood flow may become only slightly more turbulent distal to the stenosis with mildly increased velocities, and the distal pressure may be slightly decreased, but not to a high enough degree to matter. Also, when a vessel begins to occlude slowly, collateral blood supply may form on it's own (angiogenesis) or may have already existed with low blood flow and will accept larger volume (autoregulation), thereby marking the stenosis as even less significant. There are more physical principles at play, but this is roughly the explanation. Hope this helps. Good luck and all the best.  (+ info)

how important or critical is the left anterior descending artery to the heart as a whole?

---

The first answer is pretty accurate. Except, a "widow maker" lesion is in the Left Main Coronary Artery. This is the artery that supplies the LAD and oher coronaries.  (+ info)

What is the risk of a less than 2mm cerebral aneurysm?

---

I had an MRA and they found a tiny saccular aneurysm measuring less than 2mm maximum diameter directed posteriorly at the origin of left A1 segment of anterior cerebral artery. I am 29 years old. Any general information about aneurysms and the danger of the location would be greatly appreciated.

Looks like there is a 1% chance each year that it could rupture. Maybe that's similar to the sum of other risks of great bodily injury like driving, going into a convenience store or going to a pizzaria in NY.

But you should find out what kinds of activities might be more dangerous and make sure your blood pressure stays good! Since,you've been to a doctor, you have probaly heard this by now.

Good luck.  (+ info)

what should i expect? aneurysm-cerebral artery?

---

I just found out that my mum has an aneurysm in
her left cerebral artery,
all i know is it's
about 5mm, they have done a lumbar puncher,
waiting for the results. they have sent her home
and want to do a coiling over the next two weeks.
She is 49 average health.

Just wanting to know what could be ahead.
thanks
Endovascular coiling is an increasingly popular treatment option, as it has a high success rate, with 77% of people making a significant improvement or a full recovery. This procedure is also less invasive compared to conventional clipping and recovery times are usually quicker.
That is from a UK hospital.

From a US site...and this is where you come in...
At home:
You may be advised not to participate in any strenuous activities. Your physician will instruct you about when you can return to work and resume normal activities.
Notify your physician to report any of the following:
* fever and/or chills
* increased pain, redness, swelling, or bleeding or other drainage from the insertion site
* coolness, numbness and/or tingling, or other changes in the affected extremity
* any changes in bodily functions or neurological changes, such as extreme headache, seizure, or loss of consciousness

...so you will have to stop your mum playing football for a bit!
There is a link to the US site which describes eveything in detail if you want to know, but don't you and your mum be scared. If nothing is done it could rupture and that is an emergency.
Look after her and I wish you both all the luck in the world.

Right posterior communicating artery aneurysm, anterior communicating artery aneurysm right otitis externa.?

---

Patient was admitted with suspicion of intracranial aneurysm. On the following day, that patient underwent a three-vessel cerebral angiogram that demonstrated a posterior communicating artery aneurysm and questionable anterior communicating artery aneurysm. The patient underwent a right craniotomy for clipping of the right posterior communicating artery aneurysm and anterior communicating artery aneurism. Postoperatively, the patient was observed in the surgical care unit until his mental status was stabilized. The palsy and ptosis noted preoperatively resolved during the post surgical course. The patient has been moving without assistance and tolerating food well. The patient was also seen by the ENT service during the hospitalization for his otitis external and their recommendations were as follows. How would you code both the principal diagnosis and any other diagnoses that arise from this case ?
Principal:
437.3 Cerebral aneurysm, nonruptured

Others:
01.24 Other craniotomy
39.52 Other repair of aneurysm
89.6 Circulatory monitoring
380.22 Other acute otitis externa
89.06 Consultation, described as limited  (+ info)

anterior artery heart surgery how common? description of procedure?

---

Is this an unusual surgery? Any particular medical center or hospital recommended for better results from this procedure?
The patient is brought to the operating room and moved onto the operating table.
An anesthetist places a variety of intravenous lines and injects an induction agent (usually propofol) to render the person unconscious.
An endotracheal tube is inserted and secured by the anesthetist or a respiratory therapist and mechanical ventilation is started.
The chest is opened via a median sternotomy and the heart is examined by the surgeon.
The grafts are harvested - frequent conduits are the internal thoracic arteries, radial arteries and saphenous veins.
The surgeon stops the heart and initiates cardiopulmonary bypass; or in the case of "off-pump" surgery, places devices to stabilize the heart.
One end of each graft is sewn onto the coronary arteries beyond the blockages and the other end is attached to the aorta.
The heart is restarted; or in "off-pump" surgery, the stabilizing devices are removed. In some cases, the Aorta is partially occluded by a C shaped clamp, the heart is restarted and suturing of the grafts to the aorta is done in this partially occluded section of the aorta while the heart is beating. This reduces time spent on the heart lung machine.
The sternum is wired together and the incisions are sutured closed.
The person is moved to the intensive care unit (ICU) to recover. After awakening and stabilizing in the ICU (approximately 1 day), the person is transferred to the cardiac surgery ward until ready to go home (approximately 4 days).
any good cardiologist at a reputable hospital
can do this surgery with the minimum of risk  (+ info)

If a patient was diagnoses with right posterior communicating artery aneurysm; anterior communicating artery?

communicating artery aneurysm; right otitis externa what is the final diagnosies and the principal diagnosis and medical code for this and the procedure code
Oh man, I knew it would come to this, medical students or doctors using Y/A! to practice medicine. What next, Supreme Court Justices asking about the Commerce Clause?  (+ info)
