Natural orifice transluminal endoscopic surgery (NOTES) is one of the most exciting concepts that has emerged recently in the surgical field. All accesses to the abdominal cavity in the porcine model using natural orifices, e.g. transgastric, transvesical, transcolonic and transvaginal, have been described and explored. The experimental feasibility of all procedures by NOTES was successfully de...

OBJECTIVE As the mortality associated with coronary artery bypass grafts has fallen, morbidity has become an increasing problem. The improvement of transluminal carotid angioplasty is enlarged to patients with asymptomatic severe carotid stenosis (> 85%) requiring coronary surgery. METHODS Between January 1993 and January 1995, 10 patients underwent percutaneous carotid angioplasty prior to c...

P ercutaneous transluminal angioplasty is an accepted treatment for stenoses of bypass graft& and for total coronary artery occlusions.3-5 It follows that the same treatment would also be appropriate for total occlusions of saphenous aortocoronary bypass grafts. This report describes our clinical experience with attempted dilatation of totally occluded saphenous bypass grafts. Of the 2,679 cons...

We used polarized light microscopy and thin-layer chromatography to determine whether embolization of atherosclerotic material occurs after transluminal angioplasty. The experimental model consisted of an in vivo perfusion system of the atherosclerotic rabbit left iliac artery. Of eight rabbits that underwent successful angioplasty, four had angiographic evidence of dissection and three showed ...

Transluminal angioplasty has shown promise as a nonoperative treatment of atherosclerotic obstruction. Despite its increasing clinical use and potential importance, little is known of its mechanism and acute effects. To evaluate transluminal angioplasty, three rabbit models of experimental atherosclerosis were developed: Group 1 (n = 20) = high cholesterol diet plus balloon de-endothelializatio...

With the introduction of the Griintzig balloon catheter, percutaneous transluminal angioplasty has gained increased acceptance and has been used to dilate lesions in the coronary [7], renal [6, 91, mesenteric [41, aorta [5], iliac [ 11, femoral [3] and popliteal [3] arteries. In lower extremity ischemia it has been used primarily to treat patients with claudication and short segmental lesions [...

Quantitative histologic examination (morphometric analysis) of pressure-perfused rabbit atherosclerotic arteries was used to determine whether compression of atheromatous material occurs with transluminal angioplasty. Experimental atherosclerosis was developed in both iliac arteries, with transluminal angioplasty performed on the left iliac while the right iliac served as a nondilated control. ...
