Hi... This is Joe Grover. I don't know if you remember me but I used to
work at MetaCtreations and am a friend of Steve Rathmann. I just wanted to
send a quick note to say that Shawn is in our heart and our prayers. I hope
that all went well with Shawn's surgery today. Blassings, Joe
Vascular Surgery: Infra Renal Abdominal Aortic Aneurysm Repair: Surgical Technique
Abdominal Aortic Aneurysm (AAA or Triple A) is an abnormal increase in the size of abdominal aorta which carries blood from the heart to supply the viscera and ...
Nice question. EVAR is always preferable when there is a good neck and no
important arteries come in the way as it is less painful and faster
recovery. But the question is that you have told that there is a narrowing
(stenosis) below the aneurysm.How tight is the stenosis?If its much it will
be better to do open surgery and tackle the narrowing at the same time.
Can you post the CT picture here?In developing countries EVAR becomes a
costly affair and hence open surgeries are commonly performed.
Impotence in such a case may be related to injury of lombo-aortic plexus
and presacral nerves which lie on anterior face of aortic bifurcation in
the retoperitoneal space and therefore may be damaged during aorto-iliac
exposition. Better way to avoid this is to open posterior peritoneum
slightly on right aspect of aorta (beware vena cava!) and actually don't
cut down retroperitoneal tissue around aortic biforcation: prepare only
common iliac arteries just for clamping, don't completely open sac
Good day Dr. Rajnish Duara, great video and, most of all, very good choice
in view angle, as one can clearly see the operation from head to toe. Being
a medical student, hoping to specialize in the surgical field, I feel the
need to ask you several question regarding this procedure, as so: 1. What
suture/thread material did you choose to suture the graft to the AA? And
what was the thread's thickness ? 2. Was the suture or anastomosis done in
an interrupted or noninterrupted manner? Thank you.
Thank you Dr. Duara for explanation. I was also wondering what the white
deposit was. My layman understanding of an aneurysm was just that the walls
become weak and and herniated and cause a bubble to form. However, in case
of the aorta there are 3 linings involved and now i understand that the
white matter may not be fat but layered blood clots. Thanks again. My
father in law has to undergo this procedure soon and he is being offered a
stent graft. However, he is a survivor of LV rupture.
Thank you Dr. Duara for your concern. It is really appreciated. My father
in law underwent EVAR with some complication where he was not put to sleep
and an additional interventional procedure from his upper arm area was
performed. I am not sure what it was as I am waiting for his full report. I
will also forward it to you. It has been 13 days and post op, he is feeling
a "stretchy" feeling in his abdomen otherwise fine. His urine and stool
movement is normal. Again, thank you and God Bless
Stephen, Usually Infrarenal aortic aneurysms do not have major arteries
involved as Coeliac and SMA had already taken off. IMA is usually
thrombosed in the involved aorta and the distal colon gets the supply from
the Marginal Artery of Drummond which is formed both by SMA and IMA. When
IMA is gone the SMA collateral supply via the marginal artery helps
preserve the blood supply. Next time, your anatomy professor asks you, tell
him that. And I hope he will know that too ;-)
Eric, The cottage cheese like material is thrombus which lines the
aneurysmally dilated aortic wall. Thrombus is nothing but blood clots. When
the aortic wall enlarges there are changes in the endothelial layer (intima
and intima-media interface) which incites a reaction on blood which results
in layered thrombus. This is the material which you have seen me removing
so that no particles can get inside the anastomotic part and cause embolism
distally to the lower limbs.
Thank you so much for your prompt answer. I'm currently in my 4th year of
med school, and had underwent 4 months in the OR, seconding through various
general surgery procedures, ranging from Inguinal Hernias, to classic and
laparoscopic cholecystectomies and so forth. I enjoy general surgery, but I
also like cardiovascular surgery. I still have 3 years of school until I
choose an actual branch of surgery to specialize in. Thank you, you have
quite a video collection.
Thanks for chipping in Luca. Our friend Stephen got confused between
impotence and infertility. Erectile impotence as you have rightly pointed
out is due to nerve related problems. I also would like to hare that
minimal handling and limited dissection is the key to a good surgery. Any
extra dissections lead to lymphatic and nerve plexus injuries. Targeted
dissections is the rule. That is one reason why Laparoscopic AAA repair has
very good results too.
... continued My father in laws report states the following: CT Angiogram:
Sacular intrarenal/aortic aneurysm with mural thrombus. starting almost 3cm
below the level of renal arteries. A stenosis was seen in distal aorta
below the level of aneurysm. Aneurysm measures 59x52x51mm with a thin wall
in ventral aspect. Would it be riskier to perform an EVAR repair on a
patient like this Dr. Duara? Your kind thoughts would be highly
appreciated. Thank you.
Thank you. I'm with Oradea's Faculty of Pharmacy & Medicine of Bihor
county, Romania. I have sustained my OR practice during summer time in my
hometown of Piatra-Neamt, it's the county's main Emergency Hospital. It is
a good exposure, but I still have a lot to learn, and a long way to go, but
I'm optimistic. I wish there'd be more doctors, like yourself, willing to
film operations, so students like myself could learn more. Wish you best of
luck.
Don't worry. Most people need anesthesia and it is better that way. I was
worried about the stenosis in the lower part of aorta and I believe that
was also tackled. Usually you require 3 vascular access, two from groin and
one from arm for EVAR. So it is routine. Maybe there was a complication
with the vascular access from the arm that required some intervention.
Yes, Mr Tom. Autopsies are also done in this manner as it is done in dead
bodies by forensic doctors and you have to do the same thing to avoid
cutting vital structures. The only difference is that the person is alive
after the surgery and the forensic doctor need not bother about that 'small
little part' of life and death ;-) Adios.
Stephen: The testicular arteries may get involved in the aortic aneurysm.
Even if they are compromised due to the pathology or grafting, the testes
will receive collateral from cremasteric, pudendal, etc. So virility will
not be a problem. Impotence is related to erectile dysfunction which is not
at all related to testes!!!!!
Great Video!! Really helpful for my anatomy and physiology class. However,
I got one question regarding what will happen to the arteries leading to
the gonads and the intestine? Will they not get no more blood supply since
that section is now covered with the graft? Thank you in advance.
1. Suture material used in this case is 4-O polypropylene suture. 2. It was
done by Matas's inclusion technique in a continuous fashion. Thanks for the
wonderful comments. Much appreciated. Wish you all the best for your future
surgical career. Where are you studying?
Thank you for your reply Dr. Duara. It is much appreciated. Unfortunately,
I am unable to get those details at this time. If you could furnish you
contact details i would be more than willing to send them to you directly
when I receive them. Many thanks again.
Great explanation, I really appreciate it! Just one more thing though. What
happens to the gonadal arteries? I read that one of the complications of
aneurysm repair is impotence. So, I assume the arteries got blocked, but am
not sure. Thanks again :D
What was the cottage chesse like glob that was excised just befor the shunt
was put in? I am guessing plaque build up? and if so is this a contributer
to the anurism? no bacon for me thak you!
Thanks for the information. Medical education can be shared between
continents in the virtual world. This is a great tool for education and
sharing knowledge. Thanks for showing interest.
Thats already good exposure. Which medical college are you associated with?

Amazing operation Dr. Blitz. What do you think of the patient's prognosis
considering the Marfan's syndrome and old age? And I always wonder on how
do you prevent ischemic-reperfusion injury during the surgery particularly
to the heart? Thanks.
This patient's prognosis is reasonable, given the constraints of the Marfan syndrome. The good news is that she won't die of a proximal rupture, since that segment of aorta has been replaced. The answer to the question of ischemia-reperfusion injury is quite complex and fills textbooks. The bottom line is that one needs to protect the heart well and limit the degree of ischemia. I do that by systemic hypothermia and ample doses of cardioplegia, both antegrade and retrograde.
Thanks Doctor! This is so educational to our layman. I have a few
questions. 1) Can all patients undergo this procedure? Is this procedure
related to the patient's artery condition (for example, is it more
difficult or undoable for a patient who has a serious ASVD?) 2) Is the risk
of the aortic surgery with DHCT and ACP higher than other procedures
without hypothermic circulatory arrest? Thank you!
Thank you for your questions, Lei Meng. Most patients can undergo an aortic dissection repair. However, if a patient presents too late, he may not be a candidate for surgery. We do not know much about most patients who undergo the procedure prior to surgery, since most arrive very ill and incapable of giving their history. However, there are no absolute contraindications for the surgery. The risk of any type of surgery under HCA, with or without ACP, is definitely higher than for most other types of cardiac surgery. This elevated risk arises from both the nature of the disease being treated and from HCA itself.
I was surprised that the straight replacement of the aortic valve using a
'tissue valve' (pig's or bovine valve) or a metal/plastic was not mentioned
- just using the pulmonory valve. Also in a 1st World country such as the
USA or UK, getting a second opinion is simple - here in South Africa the
costs are prohibitive, as our medical aids are most unhelpful!

It hurts when I cough and laugh, I have yet to sneeze wonder how bad that
will hurt!!! I want you to know your videos were VERY HELPFUL and thanks
for sharing! I had my valve replacement Dec18 and was released Dec 23rd
have NOT had a pain pill since they took the chest tubes and wires out on
the 20th. I was scared to death about this surgery since a friend of mine
had the same surgery and died from it ( bloodclot ) a few years ago. Since
I have a mechanical valve I have to be on Coumadin, they forgot to
prescribe it to me so I went 2 and half days with out it until we figured
it out. I just want everyone to know double check everything ask lots of
questions too. It gets a lot better when you get home and get some sleep!
So comforting to hear your surgery went well! My surgery is next Thursday to replace my bicuspid aortic valve with a mechanical one, as well as a possible aortic root repair.
