What is type B aortic dissection?

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 is the ICD 10 code for type A dissection?

ICD-10-CM Coding for Aortic Aneurysm and Dissection I71. 9, Aortic aneurysm of unspecified site, without rupture. The only difference is that “dissecting” is no longer a subterm under aneurysm in the ICD-10-CM index.

What is the difference between Type A and Type B aortic dissection?

Type A which is the more common and dangerous of the two and involves a tear in the part of the aorta where it exits the heart or a tear in the upper, or ascending aorta, which may extend into the abdomen. Type B which involves a tear in the lower, or descending, aorta only, which may also extend into the abdomen.

Is aortic arch dissection type A or B?

Aortic dissections that occur in the ascending part of the aorta are called type A; those in the descending aorta are type B. These types of dissections are further classified by two categories: acute and chronic.

What is uncomplicated type B aortic dissection?

Acute uncomplicated Stanford type B aortic dissection is defined as the absence of malperfusion or signs of (early) disease progression [2] and presenting within 14 days of symptom onset. We divided the time course of aortic dissection into acute (< 14 days), sub-acute (15–90 days), and chronic (> 90 days) phases.

What is complicated type B dissection?

Complicated type B aortic dissection refers to malperfusion syndrome involving visceral, renal, or extremity ischemia, rupture or impending rupture, uncontrolled hypertension, persistent abdominal or chest pain, or findings of rapid expansion on computed tomography (CT) imaging.

What is the ICD-10 for aortic dissection?

I71.0
2022 ICD-10-CM Diagnosis Code I71. 0: Dissection of aorta.

What is thoracic aortic dissection?

A serious complication of a thoracic aortic aneurysm is an aortic dissection. This is a tear in the aortic lining. It can occur anywhere along the aorta. An aortic dissection starts with a tear in the inner layer of the aortic wall of the thoracic aorta. This can be a life-threatening emergency.

How is type B aortic dissection treated?

Uncomplicated type B aortic dissection is generally managed with optimal medical therapy, which includes pain control and strict blood pressure and heart rate control (also referred to as “anti-impulse therapy”) [1].

Can a Type B aortic dissection heal?

It has been generally recommended that patients who have type B aortic dissection without complications are treated with medical therapy in an intensive care unit. Usually, with aggressive antihypertensive therapy, up to 85% of patients may survive their initial hospital stay.

What is the prognosis of aortic dissection?

The 10‐year actuarial survival rate of patients with an aortic dissection who leave the hospital alive ranges from 30% to 60%. 20,21,22,23,26,27 The long‐term approach is based on understanding that dissection of the aorta is the epitome of systemic aortic media degeneration or defective wall structure, with the entire aorta and its branches being predisposed to dissection, aneurysm formation, and/or aortic rupture. Subsequently, management in these patients includes life time medical

What causes aortic dissection?

Uncontrolled high blood pressure (hypertension)

How serious is a torn aorta?

The condition is generally fatal in most of the cases because of the excessive internal bleeding as a result of the rupture. The aorta is the main blood vessel which carries blood out of your heart.

What is the pathophysiology of aortic dissection?

Aortic Dissection: A Review of the Pathophysiology, Management and Prospective Advances. Aortic dissection is an emergent medical condition, generally affecting the elderly, characterized by a separation of the aortic wall layers and subsequent creation of a pseudolumen that may compress the true aortic lumen. Predisposing factors mediate their risk by either increasing tension on the w ….
