All by myself -- Celine Dion
When I was young
I never needed anyone
And making love was just for fun
Those days are gone
Livin' alone
I think of all the friends I've known
When I dial the telephone
Nobody's home
All by myself
Don't wanna be
All by myself
Anymore
Hard to be sure
Sometimes I feel so insecure
And loves so distant and obscure
Remains the cure
All by myself
Don't wanna be
All by myself
Anymore
All by myself
Don't wanna live
All by myself
Anymore
When I was young
I never needed anyone
Making love was just for fun
Those days are gone
All by myself
Don't wanna be
All by myself
Anymore
All by myself
Don't wanna live
Oh
Don't wanna live
By myself, by myself
Anymore
By myself
Anymore
Oh
All by myself
Don't wanna live
I never, never, never
Needed anyone

And making love was just for fun
Those days are gone

Nobody's home

I never, never, never
Needed anyone

you have your own social circles
I have mine
now you have crossed the line
so this is the end of it

Over the rail
一個洗腎病患要放左側的 perm-cath / hickman
不知為何他的 left brachiocephalic vein to SVC 的 angle 一直過不去
我只好用兩條 0.35 wire 作 guide, 一起從 A/V port advance, 增加 support
" over the rail " method
終於成功置入了!
TIMI
TIMI stands for 'Thrombolysis In Myocardial Infarction'
'TIMI Grade Flow' is a widely adopted scoring system from 0-3 referring to levels of coronary blood flow assessed during percutaneous coronary angioplasty:
'TIMI Grade Flow' is a widely adopted scoring system from 0-3 referring to levels of coronary blood flow assessed during percutaneous coronary angioplasty:
- TIMI 0 flow (no perfusion) refers to the absence of any antegrade flow beyond a coronary occlusion.
- TIMI 1 flow (penetration without perfusion) is faint antegrade coronary flow beyond the occlusion, with incomplete filling of the distal coronary bed.
- TIMI 2 flow (partial reperfusion) is delayed or sluggish antegrade flow with complete filling of the distal territory.
- TIMI 3 flow (complete perfusion) is normal flow which fills the distal coronary bed completely

Fontaine classification
Stage I – Asymptomatic. Of note: Fontaine stage I does in fact describe patients who are for the most part asymptomatic. Careful history may actually reveal subtle and non-specific symptoms such as paresthesias. Physical examination may reveal cold extremities and other signs of “subclinical” peripheral artery disease. More examples include bruits over blood vessels and lack of normal pulses.
Stage II – Intermittent claudication. This stage takes into account the fact that patients usually have a very constant distance at which they have pain:
- Stage IIa – Intermittent claudication after more than 200 meters of pain free walking.
- Stage IIb – Intermittent claudication after less than 200 meters of walking
Stave IV – Ischemic ulcers or gangrene (which may be dry or humid).
Rutherford classification
Stage 0 – Asymptomatic
Stage 1 – Mild claudication
Stage 2 – Moderate claudication – The distance that delineates mild, moderate and severe claudication is not specified in the Rutherford classification, but is mentioned in the Fontaine classification as 200 meters.
Stage 3 – Severe claudication
Stage 4 – Rest pain
Stage 5 – Ischemic ulceration not exceeding ulcer of the digits of the foot
Stage 6 – Severe ischemic ulcers or frank gangrene

esophageal diverticula
2 categories : pulsion and traction
2 types of pulsion diverticula : Zenker's diverticulum and epiphrenic diverticulum
pulsion is due to intraluminal pressure
traction is due to adjacent tissue inflammation and fibrosis
pulsion is pseudo diverticulum ( mucosa layer only )
traction is true diverticulum ( whole layers )
Zenker's is the most common diverticulum of the esophagus

橫隔膜疝氣 diaphragmatic hernia
橫膈膜疝氣指的是腹腔內的臟器
因腹壓升高或是橫膈膜通道的鬆弛
而造成應該在腹腔內的臟器跑道了胸腔
最常偷跑到胸腔的器官就是 "胃" 了
治療橫隔膜疝氣需要手術
要嘛從腹腔把它拉回來 ( pull back )
要嘛從胸腔把它推回去 ( push in )
端看橫膈疝氣的解剖位置和外科醫師的技術
當然
已經鬆弛的橫膈通道要加強它的緊度 ( re-inforcement )
以減少日後復發

食道憩室 esophageal diverticulum
食道憩室就是食道壁的一個向外膨出
以位置來分可分為上,中,下段的食道憩室
這位病患的憩室在橫隔膜上方
屬於下段的食道憩室
hence so called : epiphrenic ( 橫隔膜上方的 ) diverticulum ( 憩室 )
上圖中畫面右上方的一球鋇劑顯影即是放射科醫師作食道攝影所發現的食道憩室
以位置來分可分為上,中,下段的食道憩室
這位病患的憩室在橫隔膜上方
屬於下段的食道憩室
hence so called : epiphrenic ( 橫隔膜上方的 ) diverticulum ( 憩室 )
由另一角度(由後往前看)之同一個食道憩室

主動脈腸道廔管 (AEF)
AEF, Aortic-Enteric Fistula
主動脈腸道廔管, 是死亡率很高的疾病
根據統計,被診斷有主動脈腸道廔管的病人,存活率是50%
兩個病人就有一個會死掉
因為主動脈是人體最大條的血管
一旦它和腸道形成一個原本不該有的通道(即所謂廔管)
可想而知患者不是大量吐血就是大量血便
出血量會很大,往往造成患者休克
緊急手術時患者就回天乏術( die on table ),也是有可能的
幸好這不是一個很常見的疾病
它好發在腹主動脈瘤手術後的病人
事實上,百分之95以上主動脈腸道廔管的病患
都有腹主動脈瘤手術的病史
治療方式:
可先以主動脈支架將廔管洞口擋住
若仍無法完封,只好以傳統開刀修補
遺憾的是,目前兩種治療的長期存活率都並不高
