چکیده

BACKGROUND Several minimally invasive saphenous vein harvesting techniques have been developed to reduce morbidities associated with coronary artery bypass grafting. This prospective, randomized study was designed to compare two commonly used minimally invasive saphenous vein harvesting techniques, the SaphLITE Retractor System (Teleflex Medical) and the Clearglide Endoscopic Vessel Harvesting System (Ethicon CardioVations, Inc.). METHODS Between January 2003 and March 2004, a total of 200 patients scheduled for primary, nonemergent coronary artery bypass grafting, with or without concomitant procedures were randomized into two groups: SaphLITE (n = 100) and Clearglide (n = 100). Pre-, intra- and postoperative data was collected and subjected to statistical analysis. Randomization provided homogenous groups with respect to preoperative risk factors. RESULTS Harvest location for the SaphLITE group was thigh (n = 40), lower leg (n = 5) and both lower leg and thigh (n = 55). The location of harvest for the Clearglide group was thigh (n = 3), lower leg (n = 16) and both lower leg and thigh (n = 81). The mean incision length was 3.6 cm (range, 2-6) in the SaphLITE group versus 2.1 cm (range, 1-4) in the Clearglide group (p < 0.05). The total incision length was 12.9 cm versus 8.9 (p < 0.05) in the SaphLITE and Clearglide groups. Conversion to the open technique occurred in 5 SaphLITE patients and 7 Clearglide patients. Intraoperative leg exploration for bleeding occurred in two of the Clearglide patients and none of the SaphLITE patients. Post-operative complications specifically related to minimally invasive harvesting technique, including a two-week post-discharge visit, were not statistically different between the groups. CONCLUSION The saphenous vein can be safely harvested utilizing the SaphLITE and Clearglide systems. While the Clearglide system allows for fewer incisions (number and length) and less harvest time, these benefits may be outweighed by the increased cost of the Clearglide system compared to the SaphLITE retractor.

Minimally invasive vein harvesting with the SaphLITE retractor system: is it really better?

BACKGROUND The value of newly developed techniques for saphenous vein harvesting remains controversial. Which technique offers the most benefits is still unknown. The aim of this study was to compare the conventional vein harvesting through a continuous skin incision method with 2 less invasive methods and evaluate surgical advantages and postoperative results. METHODS In this prospective stu...

Results of a prospective randomized study comparing a novel retractor with a Caspar retractor in anterior cervical surgery.

BACKGROUND Retraction injury might explain the soft tissue complications seen after anterior cervical surgery. A novel retractor system (Seex retractor system [SRS]) that uses a principle of bone fixation with rotation has been shown to reduce retraction pressure in a cadaveric model of anterior cervical decompression and fusion. OBJECTIVE To compare the conventional Cloward-style retractor (...

Comparing the Incidence of Residual Cholesteatoma Using two Canal Wall Down and Endoscopic-assisted Intact Canal Wall Tympanomastoidectomy Methods

Background: For many years, Canal Wall Down (CWD) tympanomastoidectomy has been the gold standard for treatment of cholesteatoma; however, this method has long-term complications for the patients. The Intact Canal Wall (ICW) tympanomastoidectomy has relatively lower complications, but access to the middle-ear recesses is difficult in this method. Therefore, endoscopy is used to visualize the un...
