ABSTRACT
Objective To demonstrate the visual results and complications of an cryopexy in combination with intravitreal injection of expending gas in the therapy of primary rhegmatogenous retinaldetachment (RRD). Methods Thirty-two cases (32 eyes) were retrospectively reviewed in this study. The RRD diagnosis was confirmed by best corrected visual acuity,slit-lamp microscope,indirected ophthalmoscope and Goldman three-mirror contact lens. All patients had undergone cryopexy with intravitreal gas injection and assisted by correct body position. Patients were followed for 6 to 24 months. Post-operative BCVA,final anatomical outcome, complications and failed cases were analyzed. Results The reattachment rate of cryopexy with intravitreal gas injection was 81%(26/32 eyes). Four eyes required additional scleral buckling. Two eyes needed additional vitrectomy with intravitreal injection of expending gas (SF6).Final retinal reattachment was achieved in all 32 subjects (100%). Postoperative BCVA was significantly improved (P < 0.01). Conclusion Cryopexy with intravitreal gas injection is a simple,less trauma, lower cost and effective surgery for primary rhegmatogenous retinaldetachment.
ABSTRACT
Objective To discuss the feasibility and safety of minimally invasive direct coronary artery bypass grafting (MIDCABG). Methods A total of 33 patients underwent small incision, off-pump, single-vessel direct coronary artery bypass grafting in this hospital from March 2001 to September 2003. Left anterior small thoracotomy was adopted in 14 patients, whereas partial midline sternotomy was conducted in 19 patients. The left internal mammary artery was anastomosed to the anterior descending artery in 31 patients, construction of the aorta root-anterior descending artery anastomosis using the great saphenous vein was carried out in 1 patient, and the right gastroepiploic artery was anastomosed to the posterior descending artery in 1 patient. Results The operative mortality was a zero. The intraoperative blood loss was 163?120 ml, and the postoperative drainage, 193?169 ml. The assisted respiration time after operation was 6 4?5 5 hours and the duration in ICU was 17 8?4 4 hours. Follow-up for 14 7?7 4 months found no deaths. Conclusions MIDCABG is a safe and reliable procedure, offering minimal invasion, less blood loss and fewer complications.
