Internal hemorrhoids drain through the superior rectal vein into the portal system. External hemorrhoids drain through the inferior rectal vein into the inferior vena cava. Rich anastomoses exist between these two and the middle rectal vein, connecting the portal and systemic circulations.

Are hemorrhoids veins or arteries?

They are composed of neither arteries nor veins, but blood vessels called sinusoids, connective tissue, and smooth muscle. Sinusoids do not have muscle tissue in their walls, as veins do. This set of blood vessels is known as the hemorrhoidal plexus. Hemorrhoid cushions are important for continence.

What are Grade 3 hemorrhoids?

Grade 3 – Hemorrhoid protrudes through the anus during straining or evacuation but needs to be manually returned to position. Grade 4 – Hemorrhoid remains prolapsed outside of the anus.

What are the benefits of excision of thrombosed external hemorrhoids?

Excision of thrombosed external hemorrhoids can greatly reduce pain if performed within the first two to three days of symptoms.
