Summary
Pulsatile tinnitus, often vascular, requires prompt diagnosis due to potential severity. Arteriosclerosis and intracranial hypertension are common causes identified through medical history and imaging tests.
Area of Science:
- Otolaryngology
- Vascular Neurology
Context:
- Pulsatile tinnitus originates internally, typically from vascular sources, synchronized with the pulse.
- Accurate diagnosis is essential due to the potential for underlying serious conditions.
Purpose:
- To outline diagnostic clues for arterial and venous causes of pulsatile tinnitus.
- To present an algorithm for complementary diagnostic tests and report findings from 80 cases.
Summary:
- Diagnostic clues for arterial causes include arteriosclerosis, aberrant carotid artery, and arteriovenous malformations.
- Venous causes involve benign intracranial hypertension and high jugular bulb; systemic diseases like hypertension must be excluded.
- Diagnostic tools include medical history, otoscopy, MRI/MRA, CT, blood tests, and Doppler ultrasonography.
- Carotid artery arteriosclerosis (17.5%) and benign intracranial hypertension (10%) were the most frequent etiologies in 80 cases.
Impact:
- Provides a structured approach to diagnosing pulsatile tinnitus, aiding clinicians in identifying serious underlying pathologies.
- Highlights the importance of considering both vascular and systemic conditions in the differential diagnosis.
- Contributes to the understanding of the most common causes of pulsatile tinnitus.

In a cardiovascular examination, inspection and palpation are crucial for identifying abnormalities.

01:25Cardiovascular System Abnormal Findings II: Auscultation
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

01:15Heart Sounds
Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...

01:11Pulse Assessment Sites
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
01:12Korotkoff Sounds
Korotkoff sounds are the specific sounds heard while measuring blood pressure using a sphygmomanometer, typically with a stethoscope or a Doppler device. They are named after Russian physician Nikolai Korotkov, who first described them in 1905. These sounds correspond to turbulent blood flow in the artery as the blood pressure cuff is gradually released after inflation.

01:16Pulse
When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
