Angioscopy in vascular surgery.

Abstract

The role of intraoperative angioscopy continues to evolve. To better define the role of angioscopy in vascular surgery, a review of the recent literature was performed. The most well-established indication for angioscopy is preparation of the saphenous vein for in situ bypass; however, angioscopy has also been demonstrated to be useful in the assessment of carotid endarterectomy, femoral vein valve repair, thromboembolectomy, and may be beneficial during endovascular stent grafting. Angioscopy is now a valuable adjunct in the management of the patient with peripheral vascular disease.

Micro-optical fiber probe for use in an intravascular Raman endoscope.

We believe that we have developed the narrowest optical-fiber Raman probe ever reported, 600 microm in total diameter, that can be inserted into coronary arteries. The selection of suitable optical fibers, filters, and a processing method is discussed. Custom-made filters attached to the front end of a probe eliminate the background Raman signals of the optical fiber itself. The experimental evaluation of various optical fibers is carried out for the selection of suitable fibers. Measurement of the Raman spectra of an atherosclerotic lesion of a rabbit artery in vitro demonstrates the excellent performance of the micro-Raman probe.

Totally endoscopic robotic-guided pulmonary veins ablation: an alternative method for the treatment of atrial fibrillation.

In patients affected by isolated atrial fibrillation, epicardial pulmonary veins ablation can be performed with minimally invasive robotic-guided cardiac surgery techniques. This approach might become a feasible alternative to percutaneous transcatheter procedures. In this case report, we present a totally endoscopic robotic-guided pulmonary veins microwave ablation, on beating heart. A 64-year old male patient affected by paroxysmal atrial fibrillation was scheduled for an epicardial ablation procedure. Through three 1 cm-length port accesses, the "da Vinci" robotic system's camera and arms were introduced in the patient's chest. The pericardial reflections along the superior and inferior vena cava, as well as the transverse sinus, were dissected. Through an additional 0.5 cm-length port, a guidewire was advanced gradually across the transverse sinus, the diaphragmatic surface of the heart and the oblique sinus, finally surfacing outside the thoracic wall through the same port. Once tied to the microwave probe, the guidewire was pulled out carrying the probe inside the chest up to encircle the pulmonary veins. Once in place, a box lesion of the pulmonary veins was produced by microwave. At the 3-month follow up the patient is in sinus rhythm and so far did not longer experienced paroxysmal arrhythmic episodes.
