The brain circle of Willis is an important arterial ring at the base of the brain that connects major arteries and ensures compatible cerebral blood flow. This network keeps collateral circulation, which protects brain functions during arterial blockages or narrowing. Understanding the brain circle of Willis is critical for diagnosing and treating strokes, aneurysms, and other cerebrovascular disorders.||Business Address: SurgeonsLab AG, Murtenstrasse 50, Bern 3008, Switzerland|| Business Phone number: +1 (213) 645-8935 (USA), +41 7983929694( Switzerland)
