The supratrochlear artery anastomoses with the ipsilateral supraorbital artery and contralateral supratrochlear artery. These glomus bodies control small arteriovenous shunts or anastomoses. These anastomoses exist between the femoral artery or profunda femoris and the gluteal vessels. With modern surgical techniques, bronchial anastomoses heal well without bronchial artery reconnection. Implantation involves anastomoses (connections) of the inferior vena cava, portal vein, and hepatic artery. Other anastomoses between the carotid and vertebral arteries support this effect. The portal venous system has several anastomoses with the systemic venous system. Coronary anastomoses are anatomically present though functionally obsolete. These anastomoses of nerves form the sacral plexus and the lumbosacral plexus. It accompanies the ductus deferens into the testis, where it anastomoses with the testicular artery. The left gastric artery anastomoses with the right gastric artery, which runs right to left. It anastomoses with the suprascapular and circumflex scapular arteries. There are some anastomoses between branches of the two coronary arteries. It then anastomoses with the ascending pharyngeal and occipital arteries. It anastomoses with the musculophrenic and superior phrenic arteries.
