Background:
The aetiology of breast cancer-related lymphoedema (BCRL) is poorly understood and multifactorial. Previous work has suggested that acquired abnormalities of the axillary vein may contribute to arm swelling. This prospective study evaluated venous changes in patients with a new diagnosis of breast cancer who had surgery that included axillary lymph node clearance.
Methods:
Patients underwent arm volume measurement and Doppler ultrasonographic assessment of the axillary vein before, and at 3 and 12 months after surgery.
Results:
A complete data set was available for 70 patients. BCRL was observed in 16 per cent at 3 months and 11 per cent at 12 months. Significant alterations to venous flow patterns were observed in those with BCRL. Vein wall movement was significantly reduced after surgery for the group as a whole, but did not correlate with arm swelling. Venous stenosis with impaired flow was also observed in the absence of BCRL.
Conclusion:
Axillary clearance can cause altered flow within the axillary vein, which is associated with an increased risk of developing lymphoedema.

01:15Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular spaces.

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 the...

01:19Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
