Arterial Disease

 Peripheral Artery Disease (PAD): leading case of death worldwide. Polyvascular disease.

 Atherosclerosis: Most likely the cause of PAD. Hardening of the artery or loss of elasticity.

 Arterial Pathophysiology:

1. Occlusive disease: Atherosclerosis is symptomatic by gradually occluding the artery to the target organ or extremity. (kidneys, colon, legs, or arms)

2. Symptoms occur with critical arterial stenosis (75 % of cross sectional of lumen is obliterated)

Arterial Disease

 Aneurysmal Disease: occurs due to loss of structural integrity of vessel wall. Over time this will result in dilation and aneurysm formation.

Cerebral Revascularization

 Symptomatic: Patients who have carotid stenosis or occlusion that have exhibited a

CVA or TIA

 Asymptomatic: Patients who have carotid stenosis or occlusion that are high risk for CVA

(i.e. hypertension, hyperlipidemia, smoker, obesity, CAD, etc.)

Symptoms

 Right sided symptoms:

-Left hemiplegia or monoparesis and right eye visual loss

 Left sided symptoms:

-Right hemiplegia or monoparesis and left eye visual loss

-aphasia

Symptoms

 Visual symptoms are due to ischemia of the retina.

 Amaurosis fugax

-Transient visual loss

-”Window shade”, “flashing lights”, or

“sparks”

Cerebral Revascularization

Surgical Intervention

Carotid Endarterectomy

Or

Carotid Artery Stenting

Carotid Endarterectomy

Carotid Artery Stenting

Cerebral Revascularization

Post Operative Care

Neuro Assessment: VERY IMPORTANT. Essential for recognizing neurological deficits.

Contralateral hemiparesis: technical problem with endarterectomy with immediate return to OR. Notify team ASAP. Arterial duplex may be ordered.

Defuse neurological deficit: possible internal capsule stroke secondary to hypotensive episode.

Delayed neurological deficit: 12-24 hours postoperatively. Arterial Duplex with possible CTA of head and neck for evaluation of brain hemorrhage or CVA and evaluation of carotid.

Post Operative Care

Continued

 Dextran 40: instituted for antiplatelet purposes and may be continued for 24 hours postoperatively.

NPO until POD 1 for possible exploration.

D5 ½ NS while patient is NPO

 POD 1: Initiation of Plavix 75 mg subcutaneous daily

(if no concerns for hematoma)

 Incision: Leave dressing dry and intact until POD 1, may remove. Incision will be closed with disolvable sutures, leave open to air unless draining.

Cerebral Revascularization

Complications

Hypertension: 20 % of patients. SBP 100-140

Neck Hematoma: May compromise breathing and swallowing.

-May require immediate surgical intervention for evacuation

-Order tracheostomy kit Stat to the bedside

Local Nerve Injuries: Most common laryngeal and hypoglossal nerves presenting as temporary weakness in speech, swallowing, tongue or lip movement. Less than 0.5% result in permanent damage.

Hyperperfusion Syndrome: 1-2 % occur 3-7 days post operatively. Headache, Seizures, and Intracranial

Hemorrhage. Hypertension may accompany. Supportive management

Cerebral Vascularization

Discharge Instructions

Incision Care: Leave open to air, unless draining. Wash with antibacterial soap and water and use white wash cloths.

Immediately call 911 with patient has headache with associated decreased level of consciousness or seizure activities.

Follow up in Vascular Clinic 4 weeks postoperatively.

Discharge Medications: Plavix and pain medication

Plavix injection education.

Activity: Do not resume normal work activities until follow up apt. No driving until that time, do not return to work.

Lower Extremity Revascularization

Anatomy

Lower Extremity Vascular Disease

Symptoms

Claudication: pain at rest, present with ambulation.

Typically seen one level below the disease.

Critical Ischemia: Rest pain may be first symptoms of severe ischemia. Sharp, localized pain to forefoot to below the ankle, dependent rubor and pallor with elevation. 95% loose limb in 1 yr without revascularization.

Critical Ischemia: Non healing ulcers. (arterial vs venous)

Critical Ischemia-Gangrene: Skin and subcutaneous tissue involvement. Dry (noninfected black eschar) vs Wet (macerated, purulent drainage).

Gangrene-Dry

Symptoms Continued

 Microemboli: Blue Toe Syndrome causes blue, mottled spots over the toes. May be painful.

 Acute Arterial Ischemia: Sudden onset of extremity pain, pallor, paresthesia, pulselessness, and poikilothermia. Caused by stenotic artery or emboli if no previous vascular disease.

TREATMENT

 Treatment is based on duration, disability, progression, general medical condition, non-invasive diagnostic testing AND pathology

 Non-op management: walking program, lifestyle modification, with possible medication.

 Diagnostic Testing: Arterial duplex with segmental pressures/ABI’s (vascular lab), CTA or MRA, arteriogram, plain films, ECG (if ischemic toes-could be from a-fib), PT /PTT/INR/Platelet workup.

Operative Managment

 Percutaneous transluminal angioplasty/stenting

 Femoropopliteal or Pop-DP, etc. bypass

(saphenous vein, Dakron, ePTFE)

 Femoropopliteal percutaneous endovascular intervention

 Aortoiliac or Aortobifemoral bypass or angioplasty with or without stenting

 Thromboembolectomy

 Amputation

Post-Operative Care

 ICU stabilization after aortic operations

(stability of vitals/hemodynamics, respiratory, fluid, electrolyte, cardiac, laboratory -pcv, blood glucose, lytes, coags- management).

 Fluids: D51/2 NS 20 KCL at 75 mL/hr

Rewarm and vasodilate: bolus may be warranted

 Post op day 3-4: mobilization of fluids-may see lasix given.

Post-Operative Care Continued

Pain Control: essential for mobilization. PCA or percocet or lortab

Ambulation: PT/OT consult, POD 1

Rooke Perioperative Boots

Antibiotics: continued for 24 hours

Wound Care: remove dressing POD 1, may leave open to air unless draining. Wash with antibacterial soap and water and use white wash cloths.

Amputation Wounds: Takedown is on POD 2, will require knee immobilizer.

High Risk for Pressure Ulcers

Complications

Hemorrhage from graft: Exploration required.

Thrombis (graft occlusion) PULSES< PULSES<PULSES

Infection

Stage 1: Involving skin and dermis-wound care, antibiotics.

Stage 2: Extending to subcutaneous and fatty tissue but not graft-Exploration and washout in the OR, continued wound care and antibiotics.

Stage 3: Graft involvement-Exploration and washout in the OR with graft removal with establishment of new route of perfusion. Continued wound care and 6 weeks of IV antibiotics.

Complications Continued

 Compartment Syndrome: Caused by prolonged ischemia (> 6 hrs) then revascularization resulting in edema in the calf muscles. Leg pain with sensory deficits to the dorsum of the foot and weakness of toe dorsiflexion. Measure Compartment Pressure.

Treatment: fasciotomy.
