BRG Flashcards
Describe options for penetrating Zone II neck injury
I - observe with CTA, laryngoscopy, esophagosocopy and bronchoscopy.
II - Can explore in OR with full evaluation of carotid sheath, trachea and esophagus if you are there.
Operation for penetrating injury to Carotid.
Approach like a CEA
Have blood, shunt and bovine pericardium available.
- prep and drape with head turned.
- incision along the medial border of the SCM
- Obtain proximal and distal control of Carotid (ICE) and IJ
- open hematoma if present
- resect portion of injured carotid
- repair defect with bovine pericardium
- explore remaining structures in the neck beyond the injury.
Options for blunt carotid injury
If there is flow ith a grade IV or V injury, fix it. if no flow leave it alone. aspirin for low grade injuries.
what is reason to remove a carotid body tumor?
It will grow and develop neurologic symptoms. (minimal chance of malignancy)
Preop imaging and procedure for carotid body tumor?
Get CTA as a roadmap. consult IR for perioperative embolization.
Carotid body tumor resection?
Have a shunt and BP monitoring/meds available.
- Approach like a CEA getting control.
- clip the feeding vessel (look at yout CTA) coming off the external carotid.
- disect the tumor our at the subadventitial level of the vessel never entering the lumen if possible.
- close.
Patient stays for 24 hours of bedrest and BP monitoring.
recurrent GIST
resect all (if possible) add gleevec regardless of size/mitoses for recurrence.
Indications for resection of pancreatic cystic masses (IPMN)?
Any side branch >3cm
Any main duct.
How do you fix an Aorto-caval fistula?
Try calling Vascular for an EVAR stent.
If forced open then:
Approach like an AAA, also gaining proximal and distal control of the IVC.
Open the Aorta and “fix the fistula from the inside of the aorta”
Sew in tube graft.
FAP (multiple polyps seen on c-scope)
Send to genetics for APC
review colonoscopy to check rectum to plan the operation
Get CT scan to plan operation
upper GI.
Take to OR for pouch v ileorectal anastomosis depending on rectal sparing.
If your anastomosis doesn’t reach: high ligation of the IMA/SMA.
One medical treatment for desmoids?
Suldinac
What happens after resection for rectal cancer that got neoadjuvant?
Needs more Folfox.
see them every three months for physical exam and a CEA level.
CT scan and c-scope in one year.
Unstable patient with GSW to left colon: two options?
Give a colostomy and close.
Leave open and come back for primary anastomosis once stable.
Patient presents with anal condyloma with HIV
Make sure to check CD4 count, viral load and medical compliance.
Biopsy any irregularities as this may be a prompt for SCC of the anus (then go to that scenario)
One way to describe Cattel Brasch?
Lifting the root of the mesentery to the left shoulder to expose the IVC/Aorta.
Board answer for bad zone 3 pelvic vascular trauma. (illiac/aorta)
Ligate bleeding vessels as a damage control procedure.
Come back in <24 hours (hopefully stablilize) to perform an ax-bifem.
Infrarenal IVC injury? what can you do
can ligate.
Keep patients LE in ACE wraps to control the edema until they develop collaterals.
Suprarenal IVC injury?
cannot ligate, guerenteed renal failure.
If you can control then fix by harvesting a saphenous vein or possibly internal iliac. Fillet the harvested veinto create a rectangle, wrap that in a spiral around an appropriate sized chest tube. Sew the spiral together and use that as an interposition graft.
Cutuffs for when to perform a CEA.
Symptomatic
Asymptomatic
Symptomatic 50%
Asymptomatic 80%
Steps of a CEA
Make sure shunt and bovine pericardial patch are available.
- Incision along the anterior border of SCM
- carry down thru platysma, entering the carotid sheath protecting the vagus.
- Circumpherentially dissect the patient away from the carotid to expose the bifurcation
- divide the facial vein.
- identify disease free areas to place clamps.
- Heparinize with 80 U Heparin/kg.
- Place clamps I.C.E. (Internal, Common, External.)
- Open the area of disease longitudinally
- Place shunt, flashing out clots.
- Remove the plaque sharply taking care to leave a smooth surface.
- begin to close defect with bovine pericardium, initially over the shunt, then replacing clamps (ICE) completing anastomosis with a flash to celar potential emboli (ECI for clamps)
- Close
Two indications for carotid stent?
- recurrence of plaque after CEA
2. previous neck radiation.
Stroke in PACU after CEA?
Ultrasound to confirm blockage and reexplore neck.
Increasing hematoma in PACU after CEA?
Take back to OR for reexploration.
Venous stasis ulcer (medial malleolus)?
ABI/PVRs to rule out arterial disease. biopsy and culture order an ultrasound venous insufficiency test. venous ablation procedure. Unna boot.
