What does TEA stand for?

24 -- Chettinad Health City, state-of-art multi specialty hospital at suburban Kelammbakkam, has conducted a rare surgery ''Pulmonary Thromboendarterectomy (PTE)'' on a 54-year-old man.

It was decided to proceed with thromboendarterectomy, but he refused it.

Ventilation perfusion scans may demonstrate chronic or acute pulmonary vascular emboli or thrombosis and are an important screening tool for large central occlusive clots that may be amenable to thromboendarterectomy.

SAN DIEGO--(BUSINESS WIRE)--April 30, 1996--Cytel Corporation (NASDAQ:CYTL) announced today that results of a Phase II clinical trial with its selectin blocker, Cylexin(TM), demonstrated evidence of a clinical benefit suggesting reduction of reperfusion injury following pulmonary thromboendarterectomy (PTE), the surgical removal of chronic blood clots from the lungs.

Cytel is currently engaged in Phase II clinical trials with its nead drug candidates, Theradigm-HBV, targeting hepatitis B infection, and Cylexin, designed to prevent reperfusion injury upon restoration of blood flow following treatment for heart attack and pulmonary thromboendarterectomy (PTE), a type of lung surgery.

Cylexin is also being evaluated for its ability to reduce reperfusion injury following surgical removal of blood clots from the lungs by a procedure called pulmonary thromboendarterectomy (PTE).
