Portal Vein Embolization (PVE) is a minimally invasive procedure used to redirect blood flow in the liver by blocking off a portion of the portal vein, which supplies blood to the liver. This technique encourages the growth of the future liver remnant (FLR), the portion of the liver that will remain after surgery, to increase in size and function.

When and why do people go for Portal Vein Embolization?

People undergo portal vein embolization when they require liver surgery, such as liver resection, but have insufficient healthy liver tissue to tolerate the procedure. PVE is typically performed for individuals with liver tumours, metastases, or other liver conditions that require surgical intervention but have a risk of postoperative liver failure due to inadequate liver function. The purpose of PVE is to stimulate the growth of the FLR, enabling it to take on the functions of the portion of the liver that will be removed during surgery.

What makes Portal Vein Embolization different from other treatment options?

Portal vein embolization offers a unique treatment approach compared to other options for individuals requiring liver surgery. While traditional treatments such as chemotherapy or radiation therapy may be used to shrink tumours or manage symptoms, PVE directly addresses the challenge of insufficient liver tissue for surgery by stimulating the growth of the FLR. This technique allows for safer and more successful liver surgery by increasing the volume and function of the liver remnant, reducing the risk of postoperative complications such as liver failure.

How does life change after Portal Vein Embolization?

Life after portal vein embolization can vary depending on the individual's overall health, the extent of liver disease, and the underlying condition being treated. Following the procedure, many patients experience improvements in liver function and an increase in the size of the FLR, enabling them to undergo liver surgery with a reduced risk of complications. With a larger and healthier liver remnant, individuals may find it easier to recover from surgery and may experience better outcomes in terms of liver function and overall health. While recovery from portal vein embolization may involve some temporary discomfort and adjustments to diet and activity levels, many patients ultimately enjoy a better quality of life and improved long-term outcomes after undergoing this procedure. Regular follow-up care and monitoring are essential to ensure the success of PVE and the safety of subsequent liver surgery.
