ABSTRACT
Purpose: This study aimed to investigate the visual outcomes and anatomical changes after vitrectomy for retinal artery occlusion. Methods: Twelve patients with retinal artery occlusion (11 central retinal artery occlusion and 1 branch retinal artery occlusion) were part of this study. Our patients were treated with vitrectomy with arteriotomy or with neurotomy and arteriotomy. Complete ophthalmic examination was performed preoperatively, at 2 weeks, and 1, 3, 6, 9, and 12 months after surgery. Results: The mean preoperative best?corrected visual acuity (BCVA) was 1.94 logMAR, and the final BCVA after 12?months follow?up was 2.04 logMAR. After vitrectomy with arteriotomy, the BCVA in patients treated with neurotomy and arteriotomy was 1.65 and 2.45, respectively (P = 0.038). Conclusion: No benefits have been achieved from using vitrectomy in retinal artery occlusion cases
ABSTRACT
The optimal treatment for free-floating massive right heart thrombi remains uncertain. However, they appear to increase the risk of mortality compared to the existence of a solitary pulmonary thromboembolism. Thrombolytic therapy has been shown to be effective in most patients, resulting in complete resolution of the massive thrombus and clinical improvement. We report the echocardiographic disappearance of a free-floating right heart thrombus after thrombolysis, however, the thrombus migrated and resulted in pulmonary thromboembolism. It was successfully removed with surgery.

Treatment of acute pulmonary thromboembolism (APTE) in patients with hemodynamic instability still remains controversial. We analyzed the outcome and validity of surgical pulmonary embolectomy for APTE. Between January of 2004 to December of 2010, 15 patients underwent emergency surgical pulmonary embolectomy using cardiopulmonary bypass with beating heart. Our operative indications were ; within 7 days from onset, hemodynamic instability, bilateral pulmonary artery obstruction or unilateral obstruction with central clot and right ventricular dysfunction. Ten patients presented in cardiogenic shock, two of whom showed cardiac arrest and required cardiopulmonary resuscitation before operation. One patient required percutaneous cardiopulmonary support. Median follow up period is 33 months (range 3 to 86 months). All patients survived the operation, but 3 patients died in the hospital on post operative day 11 (massive cerebral infarction), day 18 (brain hypoxia) and day 25 (multiorgan failure). Two of them had cardiac arrest and received cardiopulmonary resuscitation before operation. Hospital mortality was 20%. And all patients left the hospital on foot except one patient who had been bedridden by myotonic dystrophy before operation. No patients died or showed symptoms of pulmonary hypertension after discharge. Prompt diagnosis and surgical pulmonary embolectomy before threatening fatal condition improves the outcome of embolectomy.
