What do you need to know about Abdominal Aortic Aneurysm?
Abdominal
Aortic Aneurysm (AAA) is becoming more and more common in Hong Kong and
is known as a “silent killer” due to its asymptomatic nature. The
prevalence of this disease is global. U.S and U.K have seen 15,000
deaths [1] and 6,000 deaths [2] respectively caused by ruptured AAAs. In
Hong Kong, more than 1,000 new cases of aortic aneurysm are reported
every year. It’s important to increase public awareness and
understanding around the disease.
The series will look into:
1: What is Abdominal Aortic Aneurysm (AAA)?
2: How common is AAA?
3: How dangerous is AAA?
4: What are the symptoms?
5: Who will have AAA?
6: How to diagnose AAA?
7: When & how to treat AAA?
An abdominal aortic aneurysm is an abnormally dilated area in the
lower part of the aorta within the abdomen [3] . The fact that it is
asymptomatic means the aneurysm is often left unnoticed and unattended
promptly.
How common is AAA?
How dangerous is AAA?
When the aorta becomes dilated, it behaves like blowing up a balloon.
When the balloon is too excessively blown up, it will rupture. Usually
when the size of aneurysm is >5cm, there is significant risk of
rupture. Rupture AAA can cause massive bleeding within short period of
time.
The overall mortality rate of a ruptured aneurysm can be as high as 100%
and the risk of rupture increases as the size of the aneurysm expands.
Once internal bleeding is caused by the rupture of aneurysm, it becomes a
life-threatening condition.

頸靜脈放導管?
早前有新聞報道,一名病人原計劃於頸部的靜脈置入導管作治療,怎知意外地插到附近的動脈,還不幸出現中風的併發症。藉此解釋一下,為何人體這麼多靜脈,偏要選擇在頸部靜脈放置導管?
靜脈血管的作用是把血液從身體各處運送到心臟;若在靜脈血管注射,藥物便會隨着血液運到心臟,再由心臟送到全身。最常見的靜脈注射位置在手部,一般會在手背或前臂的靜脈插入短短的導管,再接駁喉管以供吊鹽水、輸血、打抗生素等。這步驟簡單安全,差不多每個住院的病人都會用上,但問題是,注入的藥物要經過長長的距離才能由手部到達心臟,很多時療程用上數天,手部的靜脈便會堵塞,又要再找另一組。若有些情況需要反覆注射如癌症化療、營養素注射等,很快便無法再在手上找到靜脈,便要打頸部靜脈的主意了!
也有些情況需要在靜脈大量抽出及輸入血液,例如腎衰竭的病人需要血液透析,血癌的病人需要骨髓移植等,便需要用上較粗的導管,這些情況也是要用上頸部的靜脈。
一般在頸用的是較深層的中央靜脈,好處是夠大,可放入更粗的導管;血液流量夠快,不易被堵塞;導管會由頸部伸延至胸腔靜脈,藥物一進入血管便被稀釋,很快到心臟,再由心臟送至全身,因此臨床上這血管是經常被徵用的。但頸中央靜脈附近全是重要器官,如頸動脈、神經線、氣管、肺的頂部等。更驚嚇的是,由於位置較深,肉眼是看不見的,把鋒利的針準確地刺到靜脈再置入如飲管大的導管,說沒有風險也沒有人信吧!
但病人也不用過分擔心,如今醫學昌明,在超聲波影像的引導下,針刺能準確地刺到頸靜脈,並避開其他器官,在受過訓練的醫生手上,風險是極低的。
