IR Flashcards
Arc of Beuhler
collat arter between celiac and SMA
Arc of Barkow
free edge of omentum anast R and L gastroepiploic
Marginal artery of Drummond
anast between SMA and IMA (R, M, and L colic artery)
Large vessel vasculitis with inflamm infiltrates
GCA
- temporal arteries/branches of the ECA.
- headache, scalp tenderness, and jaw claudication.
- Polymyalgia rheumatica: pain and stiffness in the shoulder or pelvic girdle, coexists in up to 40% of cases.
- Females (2:1) males, >age 50.
- GCA also affects noncranial vessels: ascending aorta and its tributaries: brachiocephalic, L CCA, L SCA.
What drug is administered during an adrenal vein sampling procedure?
Cosyntropin.
synthetic subunit of ACTH
What agent is used for embolization for fibroids?
microspheres are used in uterine artery embolization
How common is bovine arch and what does it look like?
15%
common origin of brachiocephalic and L common carotid
Where is most common origine for adamkiewicz?
L (70%) between T8-L1 (90%)
First branch of SMA?
inf. pancreaticoduodenal
Who makes up Arc of Riolan?
L colic (IMA) to middle colic (SMA)
Vessel in the fissure of the ligamentum venosum?
replaced L hepatic artery arising from the L gastric artery
difference in position between proper right hepatic a and replaced right hepatic a?
proper is anterior to the RPV and replaced is posterior to the MPV
which internal iliac branches are part of the posterior division?
iliolumbar, lateral sacral, glueteal
(I like sex in the butt)
from where do the ovarian arteries usually arise?
ant. med. aorta 80-90% of the time
What makes up the corona mortis?
obturator and external iliac- basically any vessel you see coursing over the superior pubic rim
could hypothetically cause a type 2 endoleak.
where does the subclavian vein run in respect to the anterior scalene muscle?
anterior.
SCA runs within the triangle made by the ant scalene and middle scalene muscles
what landmark is the proximal end of the axiallary artery?
1st rib
what landmark is the start of the brachial artery?
lower border of the teres minor
what marks the beginning of the common femoral artery?
onces the external iliac gives off the inferior epigastric
what marks the start of the popliteal artery?
exiting of the SFA from the adducter/Hunter’s canal
what forms most gastic varices?
left gastric (coronary vein)
MC congenital venous anomaly in the chest?
L sided SVC
90% of the time its duplicated
MC assoc CHD is ASD
92% of the time it drains into the coronary sinus
absence of hepatic segment fo the IVC?
azygous continuation: hepatic veins drains directly into RA
also, IVC is usually duplicated with L IVC terminating in L renal vein
think: polysplenia
MC cause of aortic dissection?
HTN (70%)
