What is intramural aortic hematoma?

Aortic intramural hematoma (IMH) is a condition characterized by blood leaking through the innermost layer of the aortic wall and flowing between the inner and outer walls. This leakage does not occur due to a tear in the aortic wall and, because of this, the condition has been difficult to diagnose until recently.

What causes a descending aorta?

Thoracic aortic aneurysms are most often caused by atherosclerosis, a hardening of the arteries that damages the artery’s walls. While your arteries are normally smooth on the inside, as you age they can develop atherosclerosis.

How are intramural hematomas similar to aortic dissections?

Consequently, intramural hematoma weakens the aorta and may progress either to outward rupture of the aortic wall or to inward disruption of the intima, the latter leading to a communicating aortic dissection 2. Similar to aortic dissections, intramural hematomas are classified according to the Stanford classification 4:

Where does the haematoma of aortic hematoma begin?

This condition is thought to begin with spontaneous rupture of the vasa vasorum, the blood vessels that penetrate the outer half of the aortic media from the adventitia and arborize within the media to supply the aortic wall 2. The haematoma propagates along the medial layer of the aorta.

Who is most at risk for aortic intramural hematoma?

Typically aortic intramural haematomas are seen in older hypertensive patients. The same condition may also develop as a result of blunt chest trauma with aortic wall injury or a penetrating atherosclerotic ulcer 1,2.

What causes an aortic hematoma with no intimal tear?

An intramural hematoma, possibly caused by rupture of the vasa vasorum, leads to a concentric hematoma within the media and has no intimal tear. Penetrating atherosclerotic ulcers burrow deeply through the intima into the aortic media, which precipitates a localized intramural dissection associated with a variable amount of hematoma.

What I71 01?

2021 ICD-10-CM Diagnosis Code I71. 01: Dissection of thoracic aorta. 2021.

What is the ICD 10 code for type A aortic dissection?

I71.0
2021 ICD-10-CM Diagnosis Code I71. 0: Dissection of aorta.

What is acute aortic syndrome?

Overview. Acute aortic syndrome is a variety of acute painful and potentially life-threatening aortic pathologies that require immediate medical attention. Acute aortic syndrome includes aortic dissection, aortic ulcer, intramural hematoma and unstable or painful thoracic aortic aneurysm.

What is the survival rate of an aortic dissection?

Prognosis for Aortic Dissection Hospital mortality rate for treated patients is about 30% for proximal dissection and 10% for distal. For treated patients who survive the acute episode, survival rate is about 60% at 5 years and 40% at 10 years.

What is an aortic rupture?

Traumatic aortic transection, also known as aortic rupture, is the near-complete tear through all the layers of the aorta due to trauma such as that sustained in a motor vehicle collision or a fall. This condition is most often lethal and requires immediate medical attention.

What is type A dissection?

Abstract. Type A aortic dissection is a surgical emergency occurring when an intimal tear in the aorta creates a false lumen in the ascending aorta. Prompt diagnosis and surgical treatment are imperative to optimize outcomes.

What is ascending aorta dilatation?

Abstract. Background: The aorta is considered pathologically dilated if the diameters of the ascending aorta and the aortic root exceed the norms for a given age and body size. A 50% increase over the normal diameter is considered aneurysmal dilatation.

What is a Type B aortic dissection?

INTRODUCTION Chronic type B aortic dissection is defined as one in which the tear originates in the descending thoracic aorta and which has been present for more than 90 days.

What causes acute aortic syndrome?

Marfan’s syndrome, vascular Ehlers-Danlos syndrome, annuloaortic ectasia, bicuspid aortic valve, and familial aortic dissection are genetic conditions that often cause acute aortic syndromes.

How long can a person live with an aortic dissection?

Although specific information about overall life expectancy after aortic dissection repair is not available, a recent study from the International Registry of Acute Aortic Dissection reported that about 85% of patients who have undergone successful repair of acute dissection involving the ascending aorta remain alive …

How does an intramural hematoma affect the aorta?

Pathology. The hematoma propagates along the medial layer of the aorta. Consequently, intramural hematoma weakens the aorta and may progress either to outward rupture of the aortic wall or to inward disruption of the intima, the latter leading to a communicating aortic dissection 2.

Which is ICD-10 version of injury of thoracic aorta?

Injury of thoracic aorta. This is the American ICD-10-CM version of S25.0 – other international versions of ICD-10 S25.0 may differ.

What are the differential diagnoses of aortic hematoma?

The main differential diagnoses are: 1. Sebastià C, Pallisa E, Quiroga S et-al. Aortic dissection: diagnosis and follow-up with helical CT. Radiographics. 19 (1): 45-60. Radiographics (full text) – Pubmed citation 2.
