Abstract:
In this case report, we present an atypical case of atherosclerosis manifesting as subclavian artery atherosclerosis in a 57-year-old male patient with a history of chronic smoking and dyslipidemia. The patient developed progressive cyanosis and vascular compromise in the fingers, characteristic symptoms of subclavian artery obstruction. The diagnosis was confirmed through Doppler ultrasound and computed tomography angiography, which revealed a 72% stenosis of the left subclavian artery. Balloon angioplasty was performed successfully and without complications, restoring blood flow and improving perfusion to the affected limb.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
