Avm

AVM is an acronym that may refer to several topics. In medicine it most often denotes an arteriovenous malformation, while in Indian cinema it refers to AVM Productions, a historic film production company based in Chennai.

An arteriovenous malformation is a tangle of abnormal blood vessels that directly connect arteries to veins, bypassing the capillary bed. AVMs can occur in the brain, spinal cord, or other tissues and may be asymptomatic or cause headaches, seizures, neurological deficits, or hemorrhage. Diagnosis typically relies on imaging such as MRI, CT, and cerebral angiography. Treatment depends on size, location, and rupture risk and may include observation, surgical resection, endovascular embolization, or radiosurgery. The approach is individualized, balancing the risks of intervention against the risk of bleeding and other complications.

AVM Productions, founded by AV Meiyappan in Chennai in the 1940s, became one of India's leading film studios. The company produced numerous Tamil and Hindi films and helped shape Tamil cinema during its early decades. Its studio complex, AVM Studios, became a landmark facility for production and postproduction work and remains associated with a long legacy of classic films. The AVM brand is closely tied to the history of South Indian cinema and to a era of prolific studio-based filmmaking.
