Properly placed central venous catheters have been effective in establishing prolonged access for total parenteral nutrition infusion in ill neonates. However, malposition of the catheter may lead to lethal complications. Malposition and infusion into the epidural venous plexus is most commonly diagnosed on the basis of radiographs and has been confirmed by lumbar puncture. Several studies desc...

OBJECTIVES To describe a new 3-dimensional technique for medial canthal repositioning, precaruncular medial canthopexy (PMC), and to present an outcome study demonstrating its efficacy. METHODS Data (age, sex, cause, and initial symptoms) were collected prospectively on patients with malposition of the lower eyelid. All patients were photographed before and after surgery in a set protocol. Th...

BACKGROUND Poor positioning of an endobronchial double lumen tube (DLT) could affect oxygenation during one lung ventilation (OLV). We set out to relate DLT position to hypoxaemia and DLT misplacement during OLV. METHODS We recruited 152 ASA physical status I-II patients about to have elective thoracic surgery. The trachea was intubated with a left-sided DLT. Tube position was assessed by fib...

OBJECTIVES We evaluated the anatomic and technical factors predicting stent malposition and embolization in patients undergoing endovascular stent implantation for relief of noncoronary vascular obstruction. BACKGROUND Endovascular stent implantation provides a highly effective, minimally invasive solution to vascular obstruction in patients with structural heart disease. However, stent impla...

The Multicenter Anterior Cruciate Ligament (ACL) Revision Study (MARS) group was formed to study a large cohort of revision ACL reconstruction patients. The purpose of this subset analysis study of the MARS database is to describe specific details of femoral tunnel malposition and subsequent management strategies that surgeons chose in the revision setting. The design of this study is a case se...

The supraclavicular approach of subclavian vein catheterization is associated with the lowest incidence of malposition. We report two cases of unusual malpositions seen during central venous cathelerization of subclavian vein via supraclavicular approach. Literature search did not reveal such malpositions. The possible cause for the malposition and method to prevent it is discussed.

Impacted mandibular third molars are located between the second mandibular molar and mandibular ramus. However, ectopic mandibular third molars with heterotopic positions are reported in the subcondylar or pterygomandibular space. The usual cause of malposition is a cyst or tumor, and malposition without a pathology is rare. This case report described an impacted mandibular third molar in the p...

e increasing prevalence of the use of enteral feeding tubes during critical illness leads to the increased potential for malposition of the tube [1], which may result in severe complications. We report tracheo-bronchial malposition of feeding tubes in six mechanically ventilated patients. six multiple trauma patients with mechanical ventilation in the emergency ICU were included in this study. ...
