IR Flashcards
what is corona mortis?
anastomosis between:
- obturator A
- ext iliac or inf epigastric A
uterine fibroids –> pelvic pain –> uterine A embo –> what % of patients get longterm control of ssx?
75%
atherosclerotic renal A stenosis –> stents placed –> how will this benefit patient?
no benefit
cholangioCA –> MC site of biliary obstruction?
confluence of L & R hepatic ducts
prophylatic abx is recommended for which IR procedures? (16)
- arterial endograft
- uterine A embo
- hepatic chemo/embo
- GI embo (if hemobilia)
- partial splenic embo (if >70% spleen to be embo)
- tunneled dialysis catheter
- any central line (if high risk, ie immunocompromised)
- IVC filter retrieval (if embedded w known bowel penetration)
- venous sclerotherapy
- TIPS
- cholecystostomy, biliary drain
- neph tube placement
- liver tumor ablation
- abscess drain
- vertebral body augmentation
- cecostomy
lung biopsy –> f/u CXR to check for PTX –> when? what views?
- 1-2 hr after procedure
- PA inspiratory & expiratory
lung biopsy –> f/u CXR demonstrates PTX –> what size is considered “significant”?
20%
lung biopsy –> f/u CXR –> 20% PTX –> next step?
chest tube
lung biopsy –> f/u CXR –> <20% PTX –> next step?
f/u CXR 2 hrs later
lung biopsy –> f/u CXR –> <20% PTX –> next f/u CXR –> stable PTX –> next step?
d/c
lung biopsy –> f/u CXR –> <20% PTX –> next f/u CXR –> PTX is bigger but still <20% –> next step?
chest tube
lung biopsy –> f/u CXR –> <20% PTX –> patient is complaining of chest pain/pleurisy –> next step?
symptomatic –> chest tube
lung biopsy –> f/u CXR –> PTX –> need chest tube –> optimal placement of chest tube tip?
anterior
portal vein embolization –> done in what situation?
HCC –> neoadjuvant treatment prior to major hepatic resection
portal vein embolization –> goal?
occlude portal V of one of the hepatic lobes –> other lobe hypertrophy –> prevent liver insufficiency –> improved outcomes`
