AIM To determine the efficacy and safety of perfluorocarbon liquid as a short term postoperative tamponade in patients with retinal detachment from giant retinal tears. METHOD A retrospective consecutive case series of patients with retinal detachment from giant retinal tears who underwent vitrectomy using perfluorocarbon liquid as a short term postoperative internal tamponade. The perfluoroc...

Objective. To evaluate the morphological changes of the anterior segment using ultrasonic biomicroscopy (UBM) imaging in pseudophakic patients who underwent pars plana vitrectomy (PPV) with silicone oil or gas (C3F8) internal tamponade agent injection. Method. This prospective study included pseudophakic patients with planned PPV, divided into two groups according to internal tamponade agent: t...

INTRODUCTION Choroidal coloboma is a congenital defect caused by an inadequate closure of embryonic fissure. About 40% of the eyes with the choroidal coloboma (CHC) develop the retinal detachment (RD). It is extremely difficult to manage these cases due to the lack of pigmentation at the site of choroidal coloboma. OUTLINE OF CASES This is a case series of five patients with CHC and RD who we...

Atrial distension, rather than change in intra-atrial pressure, has been suggested as a principal mediator of release of atrial natriuretic factor (ANF). During cardiac tamponade, atrial pressures rise whereas transmural pressures and atrial stretch may not be affected. The roles of atrial pressure and atrial distension were investigated in six open-chest dogs subjected to cardiac tamponade and...

OBJECTIVES The aim of this study was to explore the incidence, causes, and outcomes of cardiac tamponade in patients undergoing transcatheter aortic valve implantation (TAVI). BACKGROUND Use of TAVI is increasing, but the procedure is vulnerable to complications, given the cohort of patients. Cardiac tamponade is a possible complication, and there is a scarcity of data on the incidence and ou...

We studied the hemodynamic effects of surgically induced regional cardiac tamponade in anesthetized dogs. Tamponade restricted to either the right or the left ventricle was compared with tamponade of either ventricle and both atria. Intrapericardial pressures were elevated to approximately 20 mm Hg. With tamponade of the right ventricle alone, aortic pressure rose from 161 +/- 3.8 to 164 +/- 3....

PURPOSE To evaluate the intraoperative changes in the donor lenticule, recipient cornea, and the reduction of interface fluid thickness during Descemet's stripping and automated endothelial keratoplasty with EndoGlide™ (Angiotech Pharmaceuticals Inc, Vancouver, Canada) donor insertion, using intraoperative spectral-domain optical coherence tomography. METHODS Prospective observational case se...

OBJECTIVE This study was designed to determine the diagnostic value of 12-lead ECG for pericardial effusion and cardiac tamponade. DESIGN Cross-sectional study. SETTING University hospital. PATIENTS Hospitalized patients with and without pericardial effusion and cardiac tamponade. MEASUREMENTS AND RESULTS In a blinded manner, we reviewed 12-lead ECGs from 136 patients with echocardiogra...

cardiac laceration from blunt thoracic trauma is not a common presentation. the rate of mortality due to this injury is very high since it is not diagnosed and treated immediately. in this study, we present the case of a 65-year-old man with blunt cardiac trauma, causing right atrial rupture and pericardial tamponade. successful management of this patient was firstly done with initial pericardi...
