Synonyms and keywords:: Penetrating aortic ulcer

Overview

Penetrating atherosclerotic aortic ulcer is ulceration of atheromatous plaque that has eroded the inner, elastic layer of the aortic wall, reached the medial layer, and produced a hematoma in the media.

Historical Perspective

In 1934, Dr. Shennan was the first to describe the term "penetrating atherosclerotic aortic ulcer".^[2]
In 1986, Dr. Stanson further defined this disorder.^[3]

Classification

Penetrating atherosclerotic aortic ulcer is classified similarly to the aortic dissection.
Learn more about the classification of aortic dissection by clicking here.

Pathophysiology

The pathogenesis of penetrating atherosclerotic aortic ulcer involves severely diseased intima in the context of advanced atherosclerosis.^[3]
The thickened intima ulcerates and this ulceration propagates through intimal layer into media and sometimes it may pass media through the adventitial layer of the aorta and leads to the formation of a periaortic pseudoaneurysm and even transmural aortic rupture.

Causes

Penetrating atherosclerotic aortic ulcer may be caused by advanced atherosclerotic disease.^[3]

Differentiating Penetrating Atherosclerotic Aortic Ulcer from other Diseases

Penetrating atherosclerotic aortic ulcer must be differentiated from other diseases that cause sudden sharp chest pain, dyspnea, and back pain. Such conditions can include aortic dissection, acute coronary syndrome, and intramural aortic hematoma.
Other differential diagnoses of penetrating atherosclerotic aortic ulcer include inflammatory aortic aneurysm and conditions causing inflammatory aortitis such as Takayasu arteritis, giant cell arteritis, Behçet disease, Kawasaki disease, rheumatoid arthritis, sarcoidosis, Cogan syndrome, ankylosing spondylitis, systemic lupus erythematosus, and Wegener’s granulomatosis.^[4]
For more information on the differential diagnosis of penetrating atherosclerotic aortic ulcer, click here.

Epidemiology and Demographics

The exact prevalence of penetrating atherosclerotic aortic ulcer is unknown.
The incidence of penetrating atherosclerotic aortic ulcer is 1.62 per 100,000 individuals worldwide.^[5]
Unlike typical aortic dissection, penetrating atherosclerotic aortic ulcers most often occur in elderly patients with severe underlying atherosclerosis.^[4]
It usually affects people in their seventh decade of life or when older. ^[3]
Penetrating atherosclerotic aortic ulcer affects men at a greater extent than women.

Risk Factors

Common risk factors in the development of penetrating atherosclerotic aortic ulcer include old age, having a smoking history, male gender, hypertension, coronary artery disease, and hyperlipidemia.^[3]^[4]^[6]^[7]
Other less common risk factors include bicuspid aortic valve, prior aortic dilatation, connective tissue disorder, and prior aortic surgery.^[5]

Screening

There is insufficient evidence to recommend routine screening for penetrating atherosclerotic aortic ulcer.

Natural History, Complications, and Prognosis

The natural history of penetrating atherosclerotic aortic ulcer include an elderly with multiple risk factors for advanced atherosclerosis who presents with acute onset chest pain and dyspnea which may progress and lead to aortic dissection.^[8]
Penetrating atherosclerotic aortic ulcer starts with the progressive increase in aortic size with subsequent aneurysm formation.^[7]^[9]
If left untreated, patients with penetrating atherosclerotic aortic ulcer may progress to develop an intramural hematoma, pseudoaneurysm, acute aortic dissection, or even aortic rupture.
Prognosis is generally poor and even worse than that of aortic dissection.

Diagnosis

Diagnostic Study of Choice

Contrast-enhanced CT imaging is the diagnostic study of choice for diagnosis of penetrating atherosclerotic aortic ulcer.

Table below provides a comparison of diagnostic imaging studies for the diagnosis of penetrating atherosclerotic aortic ulcer:^[10]


Diagnostic Modality	Diagnostic Value
Transthoracic Echocardiography	Moderate
Transesophageal echocardiography	Moderate
CT Scan	Excellent
MRI	Excellent

History and Symptoms

History and symptoms of pentrating atherosclerotic aortic ulcer may greatly overlap with those of aortic dissection. Nevertheless, lesion is usually localized and does not result in radiating pain. Patients may also remain asymptomatic. The most common symptoms include chest pain and back pain.^[11]

Physical Examination

Physical examination of patients with penetrating atherosclerotic aortic ulcer may overlap with that of aortic dissection. Nevertheless, due to the localized nature of the lesion, signs, such as absent pulse or diastolic murmur of aortic regurgitation are unlikely. Possible physical examination findings include hypotension and shock especially in the case of accompanying aortic rupture.^[11]

Laboratory Findings

There are no diagnostic laboratory findings associated with penetrating atherosclerotic aortic ulcer.

Electrocardiogram

There are no ECG findings associated with penetrating atherosclerotic aortic ulcer.

Penetrating atherosclerotic aortic ulcer^[12]

X-ray

Findings associated with penetrating atherosclerotic aortic ulcer on an x-ray may include the widening of the thoracoabdominal aortic silhouette, diffuse or focal enlargement of thoracic descending aorta, pleural effusion, and deviated trachea.^[13]
A normal chest x-ray does not rule out the diagnosis of penetrating atherosclerotic aortic ulcer.^[14]

Echocardigraphy

Tans-esophageal echocardiography has been approved to be sensitive and specific for the diagnosis of aortic diseases.^[15]

CT Scan

CT scan imaging with intravenous contrast is the diagnostic study of choice for diagnosis of penetrating atherosclerotic aortic ulcer.^[7]
Findings suggestive of penetrating atherosclerotic aortic ulcer include a localized ulcer passing from intima into aortic wall or contrast leak through a calcified plaque.
It usually affects mid to distal third of descending aorta.
Ulcer is usually defined by focal thickening or enhancement of the aortic wall.

MRI

MRI study is superior to conventional CT scan in the diagnosis of penetrating atherosclerotic aortic ulcer.^[17]
Finding suggestive of the diagnosis includes a well-defined ulcer with flow void phenomenon on T1 images.

Other Imaging Findings

Findings associated with penetrating atherosclerotic aortic ulcer on a CT angiography may include the presence of false aneurysm.

Other Diagnostic Studies

There are no other diagnostic studies associated with penetrating atherosclerotic aortic ulcer.

Treatment

Penetrating aortic atherosclerotic ulcer with false aneurysm^[18]

Medical Therapy

The treatment aims at preventing the penetrating atherosclerotic aortic ulcer to progress into aortic dissection. Indications for treatment interventions include recurrent and refractory pain, signs of contained rupture, rapidly growing aortic ulcer, and presence of periaortic hematoma or pleural effusion.^[19]^[20]
Early interventions are indicated in ulcer with a diameter greater than 20 mm.

Surgery

Surgical interventions may be indicated in penetrating atherosclerotic aortic ulcer depending on the anatomic location of the ulcer, clinical presentation and comorbidities. However, since most of the patients are poor surgical candidates due to advanced age and associated comorbidities, thoracic endovascular aortic repair (TEVAR) is used more frequently.^[20]^[21]

Primary Prevention

There are no established measures for the primary prevention of penetrating atherosclerotic aortic ulcer.

Secondary Prevention

There are no established measures for the secondary prevention of penetrating atherosclerotic aortic ulcer.

Guidelines

2014 ESC Guidelines on the Diagnosis and Treatment of Aortic Diseases (DO NOT EDIT)^[10]

 ==Overview==
-Penetrating atherosclerotic aortic ulcer is ulceration of atheromatous plaque that has eroded the inner, elastic layer of the aortic wall, reached the medial layer, and produced a hematoma in the media.

 ===Medical Therapy===
-As for type B typical [[aortic dissection]], the most widespread treatment for penetrating atherosclerotic ulcers is medical therapy.
+*The treatment aims at preventing the penetrating atherosclerotic aortic ulcer to progress into [[aortic dissection]]. [[Indication (medicine)|Indications]] for treatment interventions include recurrent and refractory [[pain]], [[signs]] of contained rupture, rapidly growing aortic ulcer, and presence of periaortic hematoma or [[pleural effusion]].<ref name="GanahaMiller2002">{{cite journal|last1=Ganaha|first1=Fumikiyo|last2=Miller|first2=D.

+*Early interventions are indicated in ulcer with a diameter greater than 20 mm.
 ===Surgery===
-Surgery is performed in patients who have hemodynamic instability, persistent pain, aortic rupture, distal embolization, or rapid enlargement of the aortic diameter (surgical repair of a penetrating atherosclerotic ulcer is generally more complex and extensive than surgical repair of type B typical aortic dissection).
+*[[Surgical]] interventions may be [[Indication (medicine)|indicated]] in penetrating atherosclerotic aortic ulcer depending on the anatomic location of the ulcer, clinical presentation and [[comorbidities]]. However, since most of the [[patients]] are poor [[surgical]] candidates due to advanced age and associated [[comorbidities]], thoracic endovascular aortic repair (TEVAR) is used more frequently.<ref name="EggebrechtHerold2006">{{cite journal|last1=Eggebrecht|first1=Holger|last2=Herold|first2=Ulf|last3=Schmermund|first3=Axel|last4=Lind|first4=Alexander Y.|last5=Kuhnt|first5=Oliver|last6=Martini|first6=Stefan|last7=Kühl|first7=Hilmar|last8=Kienbaum|first8=Peter|last9=Peters|first9=Jürgen|last10=Jakob|first10=Heinz|last11=Erbel|first11=Raimund|last12=Baumgart|first12=Dietrich|title=Endovascular stent-graft treatment of penetrating aortic ulcer|journal=American Heart Journal|volume=151|issue=2|year=2006|pages=530–536|issn=00028703|doi=10.1016/j.ahj.2005.05.020}}</ref><ref name="DemersMiller2004">{{cite journal|last1=Demers|first1=Philippe|last2=Miller|first2=D.Craig|last3=Mitchell|first3=R.Scott|last4=Kee|first4=Stephen T|last5=Chagonjian|first5=Lynn|last6=Dake|first6=Michael D|title=Stent-graft repair of penetrating atherosclerotic ulcers in the descending thoracic aorta: mid-term results|journal=The Annals of Thoracic Surgery|volume=77|issue=1|year=2004|pages=81–86|issn=00034975|doi=10.1016/S0003-4975(03)00816-6}}</ref>
