PurposeTo investigate the efficacy of lacrimal silicone intubation for the management of epiphora in patients who have previously undergone anatomically successful dacryocystorhinostomy (DCR).MethodsThe authors recruited 13 patients (4 male, 9 female) who had persistent epiphora after an anatomically successful primary external DCR and conducted lacrimal silicone intubation through the dacryocystorhinostomy site.ResultsMean patient age was 54.2 years (range 42-80) and mean follow-up was 13.8 months (range 6-30). Epiphora was resolved in all 13 patients following silicone intubation. Spontaneous tube extrusion occurred in three patients, but a new one was easily reintubated.ConclusionsLacrimal silicone intubation is a simple safe and effective procedure for patients with epiphora even after anatomically successful DCR.

Purpose: We aimed to evaluate the effectiveness of bicanalicular double silicone intubation in dacryocystorhinostomy (DCR) and canaliculoplasty for distal or common canalicular obstruction.
Methods: We reviewed the medical records of patients with distal or common canalicular obstruction who had undergone bicanalicular double silicone intubation (insertion of two tubes into each canaliculus) during external DCR and canaliculoplasty. We reviewed the records of subjects who had undergone the same surgery with a bicanalicular single intubation as control material. The tubes were removed at around 6 months after surgery. Anatomical and functional success rates of patients who were followed up for > 2 months after the removal of tube(s) were evaluated. In addition, complications related to the silicone tube were evaluated.
Results: Data for 60 eyes of 45 patients in the double‐intubation group and 69 eyes of 65 patients in the single‐intubation group were retrieved. The double‐intubation group showed higher anatomical success rates (96.5%) than the single‐intubation group (85.5%). Functional success was achieved by 53 (88.3%) of 60 eyes in the double‐intubation group and 56 (81.2%) of 69 eyes in the single‐intubation group. There was no significant difference in complication rates between the two groups.
Conclusions: Bicanalicular double silicone intubation for DCR and canaliculoplasty may be an effective mode of treatment for patients with distal or common canalicular obstruction.
Venoarterial extracorporeal membrane oxygenation (VA ECMO) is widely used in patients with cardiogenic shock. Insufficient decompression of the left ventricle (LV) is considered a major factor preventing adequate LV recovery. A 40-year-old male was diagnosed with acute myocardial infarction, and revascularization was performed using percutaneous stenting. However, cardiogenic shock occurred, and VA ECMO was initiated. Severe LV failure developed, and percutaneous transaortic catheter venting (TACV) was incorporated into the venous circuit of VA ECMO under transthoracic echocardiography guidance. The patient was successfully weaned from VA ECMO. Percutaneous TACV is an effective, relatively noninvasive, and rapid method of LV decompression in patients undergoing VA ECMO.
Extracorporeal membrane oxygenation (ECMO) has become one of the often applied mechanical support for acute cardiogenic shock. During venoarterial (VA) ECMO support, left heart decompression should be considered when left ventricular (LV) distension develops with pulmonary edema and LV dysfunction. The aim of this study was to report the results of transaortic catheter venting (TACV), as an alternative venting method, performed during VA-ECMO in patients with acute cardiogenic shock. We retrospectively reviewed the records of seven patients who underwent both ECMO and TACV between February 2013 and February 2014. Extracorporeal membrane oxygenation was performed uneventfully, and TACV was introduced under transthoracic echocardiographic guidance in all cases. Hemodynamic parameters, LV ejection fraction, and LV end-diastolic dimension (LVEDD) were measured 24 hours after initiating TACV in survivors. There were no procedure-related complications. Four of the seven patients (58%) survived. Transaortic catheter venting led to an increase in mean blood pressure in all patients (p = 0.050). There was a significant difference between pre- and post-TACV-LVEDD (59 ± 14 vs. 50 ± 12 mm, p = 0.044), with a 10-23% reduction in LVEDD in survivors. Transaortic catheter venting might be an acceptable alternative to venting procedures and useful for LV recovery during VA-ECMO in patients with severe LV dysfunction.
