Study Notes
Aneurysms
- Aneurysms are a weakening of vessels causing permanent dilation of an artery, typically found in specific sites such as cerebral, abdominal, thoracic, and peripheral areas.
- They occur at points with no support, not attached to skeletal muscle or at bends/curvature in the artery.
- Types of aneurysms include:
- Cerebral aneurysm: occurs in the brain
- Aortic aneurysm: occurs in the aorta
- Thoracic or peripheral aneurysm: named depending on the location
- Triple AAA (abdominal aortic aneurysm)
- Aneurysms can rupture, causing a pouch to form, and the main concern is the rupturing of weak aneurysms.
Types of Aneurysms
- Fusiform aneurysm:
- Affects the entire circumference of the artery
- Results in ballooning of the entire vessel
- Saccular aneurysm:
- Outpouching of only a specific portion of the artery
- Results in a pimple-like formation on one side of the artery
Characteristics of Aneurysms
- True aneurysm:
- Created by congenital or acquired problems
- Weakened by genetics or born with it
- False aneurysm:
- Resulting from trauma or injury
- Weakening of all three muscle layers of the artery
- Dissecting aneurysm:
- Blood leaks into the intima or between the media of the blood vessels
- Causes a ballooning effect, pulling apart the vessel
- Blood fills into the pocket, leading to decreased blood flow to organs
Risk Factors
- Modifiable risk factors:
- Atherosclerosis
- Hypertension
- Illicit drug use
- Hyperlipidemia
- Smoking
- Alcohol abuse
- Non-modifiable risk factors:
- Age
- Gender
- Family history
Diagnostics
- Computed tomography (CT) scan with contrast
- Ultrasonography (US)
- Medical Exam
- Patient history
Signs and Symptoms
- Initially asymptomatic
- Symptoms typically related to the site of the aneurysm
- Abdominal aortic aneurysm (AAA):
- May have abdominal, flank, or back pain
- May have a pulsing mass near the umbilicus
- Thoracic aortic aneurysm (TAA):
- May cause difficulty breathing, back pain, and hoarseness
- Brain aneurysm:
- May cause headaches, vision changes, numbness or tingling in the head/face
- May lead to seizures or difficulty concentrating
Ruptured Aneurysm: AAA
- Most severe complication of aneurysms
- Critically ill patients
- Risk of hypovolemic shock due to hemorrhage
- Signs and symptoms:
- Severe hypotension
- Diaphoresis
- Decreased level of consciousness
- Oliguria
- Loss of distal pulses
- Dysrhythmias
- Retroperitoneal bruising/hematoma
- Abdominal distention
Treatment of Unruptured Aneurysms: AAA
- Non-surgical management:
- Monitor for signs and symptoms of rupture
- Maintain normal blood pressure
- Manage hypertension to prevent rupture
- Frequent US or CT
- Educate patients on signs and symptoms of rupture
- Stop smoking, illicit drug use, or alcohol abuse
- Surgical management:
- Resection or repair
- Stent grafts
- Post-op care like other angiographies
- Complications of stent grafts: rupture, infection, bleeding, peripheral embolisms
Aortic Dissection
- Life-threatening
- Causes:
- Hypertension
- Connective tissue disorders (Marfan Syndrome)
- Signs and symptoms:
- Sharp, ripping, tearing, stabbing pain
- Diaphoresis
- Nausea/vomiting
- Fainting
- Pallor
- Rapid, weak pulse
- Apprehension
- Diagnosis: CTA to confirm, TEE at bedside if unable to transport
Treatment of Aortic Dissection
- Hospital management:
- Maintain SBP of 100-120 mmHg
- IV BP medications
- Large bore IVs for fluids and IV medication administration
- IV Morphine
- Indwelling catheter may be indicated
- Potential surgical repair
- Long-term management:
- Maintain BP less than 120/80 mmHg
- Educate on strict BP control
- Beta blockers or calcium channel blockers
- Follow-up appointments to monitor BP and adjust medication as needed
