Teflon felt wrapping repair for coronary perforation after failed angioplasty

Acute type III perforation caused by failed angioplasty is a lethal complication that often requires emergency operation. However, the presence of multiple rigid stents beneath the subepicardial hematoma disturbs optimal revascularization and hemostasis. Teflon felt (Meadox Medical Inc, Oakland, NJ) wrapping repair is a simple salvage technique that allows stable hemostasis and the rescue of the entire blood flow of the coronary artery. This procedure was successfully performed with type III perforation of the left anterior descending coronary artery on 2 patients subjected to multiple stenting.     

Risk factors for delayed graft function and their impact on graft outcomes in live donor kidney transplantation

Changes in right ventricular performance in elderly patients who underwent lobectomy using video-assisted thoracic surgery for primary lung cancer

Objective: Even though lobectomy using video-assisted thoracic surgery for primary lung cancer has been reported to be beneficial in terms of the perioperative outcome, changes in the right ventricular performance have not yet been reported. The aim of this study was to determine whether lobectomy by video-assisted thoracic surgery is also advantageous with respect to the right ventricular performance in elderly patients who are 70 years old or older.Subjects and Methods: Thirteen patients (mean age: 76 years) who underwent lobectomy using video-assisted thoracic surgery (Video-assisted Thoracic Surgery Group), and 10 patients (mean age: 76 years) who underwent lobectomy using a standard thoracotomy as a historical control group (Standard Thoracotomy Group) were studied. The hemodynamics and right ventricular ejection fraction were evaluated preoperatively, and at 6, 12, 24, and at 48 hours postoperatively.Results: Postoperative values were expressed as a percentage of the preoperative values. The systemic vascular resistance index decreased to a greater extent in the Video-assisted Thoracic Surgery Group than in the Standard Thoracotomy Group. The pulmonary arteriolar resistance index at 24 hours postoperation tended to be higher in the Standard Thoracotomy Group than in the Video-assisted Thoracic Surgery Group. The stroke index, cardiac index, and right ventricular ejection fraction at 24 hours postoperation were each significantly higher in the Video-assisted Thoracic Surgery Group than in the Standard Thoracotomy Group.Conclusion: Lobectomy using video-assisted thoracic surgery for elderly patients offers not only beneficial effects in the right ventricular afterload but also acceleration in the expected compensatory hyperdynamics during the acute postoperative phase.     

Correction of a Deformed Thumb by Distraction of the Phalanx

We used distraction osteogenesis to correct six deformed thumbs in four patients ranging in age from 4 to 7 years. Two of the patients had Apert syndrome (syndromic craniosynostosis with symmetrical syndactyly) and two had polydactyly. We used a small fixator with a ball joint and successfully corrected the angular deformity after lengthening the proximal phalanx by distraction. This single inclusive procedure was extremely useful. We found the optimal distraction regimen for the digital phalanx was a one day waiting period and lengthening at 1 mm/day. The mean healing indexes were 37.2 days/cm (range 24.2 to 41.5) in those with Apert syndrome and 64.3 days/cm in those with polydactyly (62.5 and 66.0). Our results suggest that osteogenesis at the distraction site may be quicker in patients with Apert syndrome than in those with polydactyly.     

JPN Guidelines for the management of acute pancreatitis: severity assessment of acute pancreatitis

This article addresses the criteria for severity assessment and the severity scoring system of the Ministry of Health and Welfare of Japan; now the Japanese Ministry of Health, Labour, and Welfare (the JPN score). It also presents data comparing the JPN score with the Acute Physiology and Chronic Health Evaluation (APACHE) II score and the Ranson score, which are the major measuring scales used in the United States and Europe. The goal of investigating these scoring systems is the achievement of earlier diagnosis and more appropriate and successful treatment of severe or moderate acute pancreatitis, which has a high mortality rate. This article makes the following recommendations in terms of assessing the severity of acute pancreatitis: (1) Severity assessment is indispensable to the selection of proper initial treatment in the management of acute pancreatitis (Recommendation A). (2) Assessment by a severity scoring system (JPN score, APACHE II score) is important for determining treatment policy and identifying the need for transfer to a specialist unit (Recommendation A). (3) C-reactive protein (CRP) is a useful indicator for assessing severity (Recommendation A). (4) Contrast-enhanced computed tomography (CT) scanning and contrast-enhanced magnetic resonance imaging (MRI) play an important role in severity assessment (Recommendation A). (5) A JPN score of 2 or more (severe acute pancreatitis) has been established as the criterion for hospital transfer (Recommendation A). (6) It is preferable to transfer patients with severe acute pancreatitis to a specialist medical institution where they can receive continuous monitoring and systemic management.     

Visual field defects after macular hole surgery with indocyanine green-assisted internal limiting membrane peeling

PURPOSE: To report visual field defects after macular hole surgery with indocyanine green (ICG)-assisted internal limiting membrane (ILM) peeling. DESIGN: Interventional consecutive case series. METHODS: A retrospective review of 140 eyes with macular hole after vitrectomy with ILM peeling. The group with 0.25% of ICG for ILM peeling consisted of 96 eyes. The group without ICG consisted of 44 eyes. RESULTS: Nasal visual field defects occurred in 11 eyes, temporal visual field defects in seven eyes, and concentric visual field defects in one eye. In the group with ICG, nasal visual field defects were far higher in the left eye than in the right eye. CONCLUSIONS: We speculate that the postoperative nasal visual field defects were caused by the enhanced toxicity of ICG resulting from the exposure to illumination.     

Raghib's syndrome associated with cor triatriatum--a rare surgical case report

A 27-year-old male with a history of congenital heart disease was admitted for pre-operative evaluation of a cardiac malformation. Echocardiography and cardiac catheterization revealed an incomplete endocardial cushion defect with a persistent left superior vena cava which drained into the left atrium but echo-cardiographic evidence of an abnormal intra-atrial septum was not found. The patient was placed on cardiopulmonary bypass and prepared for the surgical correction of his primary cardiac lesion. Intra-cardiac examination during reconstruction of Raghib's syndrome also revealed the presence of cor triatriatum. Reghib's syndrome is characterized by the combination of abnormal drainage from the left superior vena cava into the left atrium, the presence of an atrial septal defect and the absence of a coronary sinus. To prevent secondary complications such as a brain abscess, we redirected blood flow from the left superior vena cava to the right atrium utilizing a trimmed woven dacron vascular graft that was placed in the intra-atrial position. Mitral valvoplasty, excision of the obstructing diaphragm and atrial septation were also performed successfully. Although the literature has described the surgical repair of Raghib's syndrome, its correction in combination with cor triatriatum is considered to be extremely rare.
