[Left atrial thrombus. Its evolution with oral anticoagulation].

UNLABELLED: Left ventricular thrombi were found in 25 patients by two-dimensional echocardiography. All patients were in atrial fibrillation, 16 had mitral or mitroaortic valve diseases and nine mitral or mitroaortic bioprosthetic valves. Nine patients (36%) had history of arterial embolism. At diagnostic time, oral anticoagulation with coumadin was instaured in all the patients. Periodic clinic and echocardiography follow-up was performed. Left atrial thrombi either disappeared (18 patients [72%]) or reduced their size (one patient). Six patients with mitral stenosis were considered as candidates to percutaneous mitral valvuloplasty, which was performed in 4 patients whose thrombi disappeared with anticoagulation therapy in 6 months. During the follow-up one patient had cerebral embolism without sequelae. CONCLUSIONS: 1st. Patients with left atrial thrombi have high risk for arterial embolism. 2nd. Left atrial thrombi disappear in a high proportion after prescribing oral anticoagulation, which has some important therapeutic implications.

Nonflammable endotracheal device for CO2 laser ablation of benign laryngeal and proximal tracheal tumors.

A Holinger aspirating tube may be utilized as a nonflammable endotracheal device during CO2 laser ablation of benign laryngeal and proximal tracheal tumors. Adequate jet ventilation may be performed through this small diameter (3.0 mm), metallic device while providing an unobstructed view of the surgical lesion. This technique was well-accepted by surgeons during the clinical trials. Because the 3.0 mm outside diameter was significantly smaller than the smallest flexible, uncuffed metal endotracheal tube currently available (6.9 mm), the rigid structure facilitated atraumatic insertion past the surgical lesion. Both the use of this device and the required anesthetic technique are described in three CO2 laser ablative procedures. The authors consider that this device increases safety during this potentially hazardous procedure by eliminating the flammable polyvinyl chloride endotracheal tube and cottonoid packings most frequently used during this procedure.
