“Finally, acute pulmonary embolectomy may be beneficial in the unstable patient who has not responded to conventional treatments.”
“Surgical embolectomy is restricted to life threatening proximal thrombosis where all else has failed.”
“A therapeutic approach to a patient who fails thrombolytic therapy, anticoagulation and placement of a filter includes surgical or catheter embolectomy.”
“Such pulmonary embolisms, leading to sudden death, can stem from immobilisation, multiple trauma and dehydration.”
“Insufficient removal of these air embolisms may result in serious water stress which may lead to early leaf wilting as previously shown in chrysanthemum cut flowers.”
“Pulmonary embolisms occur when these blood clots travel toward the heart and block blood flow in the lungs.”
