Pre-Test (Cardiothoracic, PVD, Urology, Ortho) Flashcards
Most common test used for predictor of post-op pulmonary reserve
Post op FEV1 > 60%
Lung cancer treated w/ only chemo and radiation
Small cell
What is empyema
Accumulation of pus in the pleural cavity
>6 weeks duration suggests fibrin deposition and decortication is needed
SVC syndrome almost always due to
Malignancy (usually bronchogenic carcinoma)
Initial tx of lung abscess
Ab aimed at causative organism (will usually resolved without drainage)
Indications for operation in descending aortic aneurysms
End organ failure, continuation of pain, rupture or signs of impending rupture
Operation for diffuse esophageal spasm
Myotomy along the length of the manometric abnormality
First diagnostic step after severe chemical ingestion
Esophagram w/ water soluble contrast to look for rupture
First test in suspected Boerhaave
Contrast esophagram (Barium if suspected in chest, Gastrografin if suspected in abdomen)
Management of chylothorax
Chest tube and low fat diet (repair basically impossible)
When can CABG or PCI be used for MI
Two vessel dz or proximal LAD obstruction
Initial tx for thoracic outlet syndrome
Exercise program to strengthen should grilled muscles and decrease shoulder droop
Primary treatment of bronchial carcinoid
Resection (lobectomy or lesser resection as long as the tumor is gone)
What is needed after barium swallow shows achlasia
Esophageal motility test since other disorders may mimic achlasia
What CT disorder would you look for in a patient with AR pupil
Thoracic Aortic aneurysm
Exophthalmos from tricuspid regurg by?
Produces markedly enlarged venous pressure
First line drug in tx of neurogenic shock
Phenylephrine
Drug ass w/ increase in urine output in hypotensive, septic patients
Norepi (acts on alpha and beta)
If oliguric right after cardiac surgery, good test for reason
Pulm Art Cath –> Will determine volume status and cardiac status
Best test to evaluate the colon for early ischemia
Sigmoidoscopy
Lymphedema that manifests its self early in life but not at birth
Lypmhedema praecox
Most common area of ischemia after AAA repair
Sigmoid
Best management for atherosclerosis
Aspirin, Lipid Lowering drugs, Lifestyle (no smoking, exercise)
Best predictive test for perioperative ischemic cardiac events in patients undergoing non-cardiac surg
Dihyridamole-thalium imagin to find reversible perfusion defects
Best management for patients presenting with acute arterial insufficiency w/ neurologic compromise of LE
Immediate surgery (Embolectomy)
Most common peripheral artery aneurysms
Popliteal (53% are bilateral)
Best first test for suspected acute mesenteric ischemia
Mesenteric angiogram (will differentiate b/w embolic or non-occlusive due to low Cardiac index)
What veins can’t be visualized by duplex US
Proximal veins (not accesible due to anatomic location)
Old frail person w/ bilateral iliac artery occlusion surgery
Axillofemoral bypass graft
Stones > what size need lithotripsy
1cm
Medicine to try for pt’s w/ bilateral undescended testis
Chorionic gonadotropin –> if not help after one month need surgery before age 2
Surgery to resolve testicular torsion
Orchiopexy –> fixes testicles in place
Tx for RCC
Radical nephrectomy (may be cure even w/ enlarged nodes because those may be reactive)
Absolute indication for surgery in pt’s w/ BPH
Recurrent UTIS, retention refractory to medical therapy, upper tract dilation, renal inuff 2/2 outflow obstruction, bladder stones
First test for suspected rupture of urethra
Retrograde urethrogram
Given massive amounts of muscle damage during open fractures, what are liberally performed
Fasciotomies
Posterior boundary of shoulder joint? Laterally by?
Posterior by teres minor and infraspinatus
Lateral by deltoid
Injury to the wrist at the radial nerve would cause
Mostly sensory abnormalities (more proximally would cause extensor abnormalities)
When is external fixation used in ortho trauma
Most often in the setting of high engr. trauma with significant soft tissue and vascular injury, or in polytrauma as “damage control”
What is osteitis fibrosa cystica
Ass w/ hyperparathyroidism –> inc bone turnover w/ elevated alk phos
brown or osteoclastic tumors and bone cysts may be present on long bones
Bone tumor where pain is relieved by aspirin
Small lucency on X-ray surrounded by reactive sclerosis
