Transcranial Doppler detection of venous-to-arterial circulation shunts: criteria for patent foramen ovale.
As paradoxical embolism is associated with stroke in young adults, migraine, and decompression sickness, the detection of venous-to-arterial circulation shunt (v-aCS), such as patent foramen ovale (PFO), is increasingly important. We compared a rigorous transcranial Doppler (TCD) protocol with transesophageal echocardiography (TEE) to develop criteria for PFO. ⋯ The standardized TCD protocol is sensitive in the diagnosis of PFO and with the use of provocation maneuvers measures the functional importance of v-aCS more accurately than TEE.

We report a case of a 36-year-old male who presented with a pulsatile mass at the left temporal region after a head injury. Duplex sonographic examination confirmed the diagnosis of traumatic pseudoaneurysm of the superficial temporal artery. Imaging showed the pseudoaneurysm was partially thrombosed.
