Study Notes

Aneurysm Overview

An aneurysm is an abnormal bulge or dilation in the wall of a blood vessel, typically an artery.
It occurs when a weakened area of the blood vessel expands under pressure, creating a risk of rupture.

Common Locations

Aneurysms most commonly form in arteries supplying the brain (cerebral aneurysm) and the aorta (aortic aneurysm).
Other locations include peripheral arteries, typically in the legs and abdomen.

Primary Characteristic

The defining feature of an aneurysm is the localized, balloon-like enlargement of a blood vessel due to structural weakness.

Contributing Factors

Contributing factors for aneurysm formation include:
- High blood pressure (hypertension)
- Atherosclerosis (hardening of the arteries)
- Genetic predisposition (hereditary conditions)
- Trauma or injury to blood vessels
- Infections affecting blood vessels (such as syphilis)

Consequences of Untreated Aneurysm

An untreated aneurysm can lead to serious health risks, including rupture, which may result in life-threatening internal bleeding and organ damage.
Rupture often leads to complications such as stroke in cerebral aneurysms or death in the case of aortic aneurysms.

Key Terminologies

Aneurysm: Localized dilation of an artery at a weak vessel wall.
Angioplasty: Balloon-tipped catheter procedure to dilate stenotic blood vessels.
Ankle-brachial index (ABI): Ratio of ankle to arm systolic pressures; measures arterial disease severity.
Arteriosclerosis: Thickening of muscle fibers and endothelial lining in small arteries.
Atherosclerosis: Inflammatory process characterized by lipid and fibrous tissue build-up in arteries.
Bruit: Sound from turbulent blood flow through narrowed or irregular vessels.
Duplex ultrasonography: Imaging technique combining gray-scale and Doppler to assess blood vessels.
Dyslipidemia: Abnormal blood lipid levels, including high LDL and low HDL.
Hematopoiesis: Process of blood cell formation and maturation.
Hemoglobin: Iron-containing protein in red blood cells responsible for oxygen transport.
Hypertensive emergency: Significantly elevated blood pressure with potential organ damage.

Anemia

Defined as lower than normal hemoglobin concentration; results from decreased erythrocyte count.
Symptoms severity correlates with rapidity of anemia's onset.
Critical assessments include cardiac status (tachycardia, dyspnea) and gastrointestinal function (nausea, melena).
Treatment options include oxygen supplements, transfusions, and IV fluids.
Compliance with prescribed therapies emphasizes understanding the purpose and management of medications.

Vitamin B12 Deficiency

Caused by inadequate intake, impaired absorption (e.g., Crohn's disease), or absence of intrinsic factor.
Symptoms can take years to develop due to significant stores in the body.
B12 replacement is required for life in cases of pernicious anemia, usually administered via intramuscular injections.
Symptoms include fatigue, pallor, neurological deficits; monitor skin and neurologic stability.

Blood Vessel Disturbances

Arteriosclerosis: Refers to the thickening or hardening of arterial walls.
Atherosclerosis: A specific type of arteriosclerosis marked by plaque formation.

Hypertension

Defined as systolic BP >140 mm Hg or diastolic BP >90 mm Hg, based on multiple measurements.
Classifications range from normal (systolic <120/diastolic <80) to Stage 2 (systolic >160/diastolic >100).
Major risk factor for cardiovascular disease, heart failure, stroke, and kidney failure.
Secondary hypertension may arise from identifiable causes such as renal artery narrowing or certain medications.
