History of Present Illness

• Chief complaint: Symptomatic (ipsilateral TIA, amaurosis fugax, minor stroke) or asymptomatic (screening/bruit)
• Indications (guideline): symptomatic stenosis 50-99% (greatest benefit 70-99%, treat within ~2 weeks of event); asymptomatic ≥60-70% in selected patients with low surgical risk and reasonable life expectancy
• Degree of stenosis, recent symptoms/timing, contralateral status

Past Medical History

• Cardiac disease (CAD common — perioperative MI risk; clearance), hypertension, diabetes, smoking, hyperlipidemia
• Contralateral carotid occlusion (affects shunting/risk), prior neck surgery/radiation/CEA (re-do — relative indication for stenting), antiplatelet/anticoagulation
• Standard PMH; continue aspirin perioperatively

Imaging Review

Carotid Duplex Ultrasound + CTA/MRA (± DSA)

• Degree of stenosis (NASCET criteria), plaque morphology (ulceration, echolucency), contralateral carotid, tandem/intracranial disease
• Bifurcation height (high bifurcation → exposure difficulty), arch anatomy (if considering stenting)

  Brain imaging

• Prior infarcts, exclude large recent infarct (timing of surgery)

Labs

• CBC, BMP, Coags, type and screen; cardiac workup as indicated

Neurological Examination

• Focal exam (prior deficits), document baseline; cranial nerves (baseline for comparison — CN injury risk)

Surgical Planning

Case Logistics, OR Needs & Orders

• OR setup: vascular tray, microscope/loupes per surgeon, patch/shunt options, EEG/SSEP/stump-pressure or cerebral oximetry plan, heparin/protamine plan, and duplex/CTA reviewed for level and plaque morphology.
• Special needs: strict perioperative BP targets, aspirin/statin continuation, antiplatelet/anticoagulant plan, airway hematoma response plan, and cranial nerve baseline documented.
• Immediate postop orders: neuro checks, neck hematoma/airway watch, BP floor/ceiling, swallow/voice assessment, antiplatelet/statin orders, drain if used, and duplex/clinic follow-up.

CEA vs CAS

• CEA preferred for most (durable); carotid stenting (CAS) for high surgical risk, hostile neck (radiation/re-do), high bifurcation (see carotid-stenting)

Position

• Supine, neck extended and turned away from operative side, shoulder roll; regional (cervical block — awake neuro monitoring) or general anesthesia

Key Surgical Steps

1. Longitudinal incision along the anterior border of the SCM (or transverse skin crease)
2. Dissect to the carotid sheath; identify and protect cranial nerves (vagus, hypoglossal, marginal mandibular branch of facial, superior laryngeal, ansa cervicalis)
3. Expose common, external, and internal carotid; encircle with vessel loops
4. Systemic heparin
5. Clamp ICA, CCA, ECA (sequence); monitor for ischemia (awake exam, EEG/SSEP/stump pressure) — place a shunt if ischemia/low stump pressure/contralateral occlusion
6. Arteriotomy along the CCA into the ICA across the plaque
7. Endarterectomy — develop the plane, remove the atheromatous plaque, feather the distal endpoint (tack down intimal flap if needed), remove debris
8. Close arteriotomy (patch angioplasty — vein/Dacron/bovine pericardium — reduces restenosis, or primary)
9. De-air, restore flow (ECA first, then ICA — flush debris to ECA), remove clamps
10. Hemostasis, ± drain, layered closure (platysma, skin)
11. Reverse heparin (protamine) selectively; complete neuro check

Critical Anatomy & Structures at Risk

1. Cranial nerves: hypoglossal (XII) (tongue), vagus/recurrent laryngeal (hoarseness), marginal mandibular (VII) (lip droop), superior laryngeal, glossopharyngeal (high exposure)
2. Carotid artery — embolization (manipulation), thrombosis, intimal flap
3. Cerebral ischemia during clamping (shunt decision), reperfusion/hyperperfusion

Equipment

• Vascular set, shunt (Javid/Pruitt), patch material, vascular sutures, heparin/protamine
• Neuromonitoring (EEG/SSEP) or awake setup, Doppler, loupes

Monitoring

• EEG/SSEP / stump pressure / awake neuro exam (cerebral perfusion during clamp — guides shunting)

Anesthesia

• Regional (awake monitoring) or general; strict BP control (avoid hypo-/hypertension — perfusion and hyperperfusion), continue aspirin, cardiac monitoring

Potential Complications

1. Stroke (embolic/thrombotic — peri-clamp, plaque manipulation), cranial nerve injury (XII, vagus/RLN, marginal mandibular)
2. Neck hematoma → airway compromise (emergent evacuation), hyperperfusion syndrome (headache, seizure, hemorrhage — BP control)
3. Restenosis, MI (cardiac comorbidity), wound issues, bradycardia/hypotension (carotid sinus)

Operative Note Template

Preoperative Diagnosis: [Symptomatic/asymptomatic] [left/right] internal carotid artery stenosis ([__]%)

Postoperative Diagnosis: Same

Procedure: [Left/Right] carotid endarterectomy [with shunt] [with patch angioplasty]

Surgeon / Assistant: Anesthesia: [Regional cervical block (awake) / general] EBL / Fluids: Adjuncts: Loupes/microscope, shunt available, heparin/protamine, Doppler; EEG/SSEP or awake neuro exam, stump pressure Implants: [Patch — vein/Dacron/bovine pericardium] Complications: None

Indications: [Age]yo [M/F] with [symptomatic (ipsilateral TIA/stroke) / asymptomatic] [__]% ICA stenosis meeting guideline criteria for revascularization, with acceptable surgical risk. Aspirin continued. Risks (stroke, cranial nerve injury, neck hematoma/airway, hyperperfusion) discussed.

Description of Procedure: After consent and time-out, [regional cervical block / general anesthesia] was provided with strict BP control and neuromonitoring. An incision along the anterior border of the SCM was made and the carotid sheath entered, identifying and protecting the cranial nerves (hypoglossal, vagus/RLN, marginal mandibular, superior laryngeal). The common, external, and internal carotid were exposed and encircled, and systemic heparin given.

The ICA/CCA/ECA were clamped (sequenced) with cerebral monitoring ([awake exam/EEG/SSEP/stump pressure]) guiding [shunt placement / no shunt needed]. An arteriotomy was made across the plaque and the endarterectomy performed, removing the atheroma and feathering/tacking the distal endpoint. The arteriotomy was closed with [patch angioplasty / primarily]. Flow was restored after de-airing (ECA first, then ICA), and a completion neuro check/Doppler confirmed patency. [Heparin was reversed with protamine.]

Hemostasis was confirmed [± drain] and closure performed in layers. The patient was transferred with strict BP control and neck/airway monitoring.

Postoperative Plan

• Step-down/ICU, neuro checks q1h, strict BP control (avoid hyper-/hypotension — stroke/hyperperfusion/hematoma)
• Monitor neck for expanding hematoma (airway emergency) — bedside evacuation if airway compromised
• Cranial nerve assessment (tongue, voice, lip), continue aspirin/statin
• Watch for hyperperfusion syndrome (severe headache, seizure → BP control, imaging)
• Carotid duplex follow-up (restenosis surveillance), risk factor modification; cardiology follow-up

Chief-Level Case Review

Use these as the senior-level mental model for Carotid Endarterectomy (CEA):

• Decision point: The operation is won or lost on control: identify inflow, outflow, perforators, collateral options, and the fastest route to temporary control before exposing the lesion itself.
• Technical lever: Do not accept a cosmetic result over physiology: ICG/Doppler/DSA, branch patency, perforator preservation, and parent-vessel caliber matter more than how the clip or resection bed looks.
• Bailout: Have a rupture or ischemia script ready: lower pressure, suction strategy, temporary occlusion time, heparin/reversal plan, bypass/reconstruction threshold, and postop BP targets.
• Postop watch: Postop danger is delayed: vasospasm, thromboembolism, hyperperfusion, hemorrhage, edema, hydrocephalus, and seizure plans need explicit orders.

Common Pimp Questions

Use these to pressure-test preparation for Carotid Endarterectomy (CEA):

1. What is the proximal-control plan before the lesion is manipulated?
2. Which branch, perforator, or venous structure is most likely to be injured in this exposure?
3. What are the intraoperative rupture steps, including temporary clip, suction, BP, and backup clip strategy?
4. What confirms treatment success: ICG, Doppler, puncture/deflation, DSA, or postoperative CTA?
5. What postoperative BP, vasospasm, antiplatelet, or anticoagulation issue changes the orders tonight?
