pseudoaneurysm

there is nothing pseudo about a pseudoaneurysm except that it is not actually an aneurysm. where an aneurysm expands the wall of a blood vessel, in the pseudo variety the blood escapes from the vessel altogether creating a ballooning of turbulent blood flow outside the vessel's constraints. both may burst, but, seeing that the one in a sense has already burst, when it bursts again it is not an understatement to say this is not a good thing. at that moment you hope there is someone who knows what to do. or in other words you are not in rural south africa.

it was during my witbank days (way back when i started blogging). i was up in my office (a thing no self respecting surgeon should ever have) trying to fend off the boredom, probably by blogging, when the call came in. it was the radiologist, an old man who worked in the state hospital as part of his semi retirement gig. he didn't sound happy, very unusual for a radiologist. he told me that he had done a sonar for a pseudoanuerysm of the brachial artery (the upper arm) and the thing had burst. he had then called the surgeon on call, a medical officer, which is usually the best you are going to get in the state. he felt the medical officer wasn't showing due urgency and was worried she didn't have things under control. he had therefore gone over her head and called me. i ran.

i entered the room. there was blood everywhere. the upper arm had been bandaged closed, but still there was bright red blood oozing from the bandage and expanding a new puddle of blood below it. the patient was already confused, and very pale. i was worried. i took over.

soon the medical officer had been sent off to theater to get them ready for the worst eventuality. a junior doctor had been delegated to get blood. i got better lines up for fluid and moved the patient to theater. quite soon we were ready to operate. when i took the bandages off in the controlled environment of theater, i was honestly shocked. there was about a 10cm diameter area of necrotic skin stretched tight over a very large mass that apparently had been pulsatile before the application of a tourniquet. i wanted to know how this had been allowed to happen. pressure necrosis is not something that happens suddenly without warning.

the patient had presented to a peripheral hospital with a pulsatile swelling in the brachial area about a month after a common or garden stab wound to that area. the peripheral doctor had made the tentative diagnosis of pseudoaneusysm and phoned the surgical medical officer at our hospital. she apparently told him that we would not accept the patient until there was a sonar confirming the diagnosis. the poor peripheral doctor obediently phoned the radiology department where he was given an appointment in two weeks time. he then admitted the patient and observed the aneurysm expand before his eyes. finally he was observing pressure necrosis developing in the skin overlying the aneurysm. one can say he didn't think to contact the surgical department again but he rested secure in the fact that a so called surgeon had told him he could wait and wait he would. after all it wasn't his mother or brother or friend and he wasn't going to be sued in the state health department, so why should he care? this is, after all, africa the continent of selfishness and cheap life.

when the patient finally ended up before the radiologist, he went ahead with the sonar although it was clear there was a large area of necrosis over a pulsatile mass. how could he know that the gentle pressure of his sonar probe was all that was needed to allow the pseydoaneurysm to break through the skin and cause a massive pulsatile bleed. thjat is when he called the surgical medical officer. i suppose one could say that at least it happened when the patient was at our hospital and not still at the peripheral hospital.

i had to debride the wound and repair the artery with a venous interposition. only problem was that after debridement i didn't have tissue to cover my graft. i tunneled it as best i could and hoped for the best.

a few days later we amputated when the graft burst.

tia

it took me a while to get around to watching it but what a worthwhile movie. there were a few things that i think i as a south african probably appreciated more than most international viewers. for one, the accent that leonardo pulled off and maintained for the whole movie was almost spot on. not just the accent mind you, but some of the idiosyncracies of how south africans talk. brilliant.

but the one line that really hit home was when they said "tia" (this is africa). that was the blanket phrase excusing all the monstrocities that this continent can dish up. for those of you who read my last post and it's comments will know i was recently a first hand witness to exactly that. tia. i have mentioned before that life is cheap in africa. but the truth of the matter is the people that make life cheap make sure it is other people's lives that are cheap, not their own. a recent illustration of this was recently when our illustrious government so steadfastly refused to admit the link between hiv infection and aids. they therefore refused to supply the populus with the much needed drugs, even claiming the drugs were killing the people, not hiv. bearing in mind the people weren't getting the drugs, the logic is difficult to follow. but some of the self same politicians, on medical aid obviously, themselves were taking antiretroviral treatment. they weren't willing to take the individual chance of dying, but they were quite willing to force thousands of others to do just that.

the patient in my previous post still has not been operated or transferred to a center where she can get the necessary care. i doubt she will. this despite the fact that i personally phoned the super and expressed my willingness to operate her free of charge even though they had officially banned me from working in the state hospital. the point they want to make against me is more important than the patient's life, so they didn't consent. and what is the point? the fact that i continued to supply a service there despite their laxness in giving me a legitimate post paints them in a politically bad light. they would rather give the appearance of not having lost control than welcoming any help in a desparate time.

yes, this is africa and life is cheap, but i can honestly say the fact that i have been barred from helping this specific individual is absolutely devastating to me. i just can't see that it is worth it to sacrifice her for their point.
