INTRODUCTION: There are many techniques to identify vessels in perforator surgery, each with specific disadvantages. Handheld Dopplers are easy to use, but inaccurate with respect to the exact localisation of the perforator. Angio-CT is invasive, time consuming, and expensive. In contrast, duplex sonography is a reliable, easy-to-use and availabe alternative for pre-, intra-, and postoperative visualisation of vessels. Power Doppler further increases sensitivity and allows visualisation of vessels smaller than 0...

OBJECTIVE: Tricuspid valve reconstruction using a small intestinal submucosal porcine extracellular matrix (ECM) tube graft is hypothesized to be durable for six months and show signs of recellularization and growth potential. The purpose was to histologically and biomechanically test ECM valves before and after six months of implantation in pigs for comparison with native valves. METHODS: Ten 60 kg pigs were included, which survived tricuspid valve tube graft insertion...

REVIEW
David J Barron, Phil Botha
Pulmonary atresia with major aortopulmonary collateral arteries (MAPCAs) is one of the most challenging surgical conditions to manage-not only because of the technical complexity of the surgery but also in terms of defining the anatomy of the pulmonary vasculature, the timing of surgery, and decision making on staged vs complete repair. The importance of early definition of pulmonary blood supply is paramount, establishing which areas of the lung are supplied by MAPCAs alone and which have dual supply with the native system (noting that 20% of patients have absent intrapericardial native vessels)...

BACKGROUND: Right ventricular (RV) remodeling involves changes in size, wall thickness, function, and shape. Previous studies have suggested that regional curvature indices (rCI) may be useful for RV shape analysis. The aim of this study was to establish normal three-dimensional echocardiographic values of rCI in a large group of healthy subjects to facilitate future three-dimensional echocardiographic study of adverse RV remodeling. METHODS: RV endocardial surfaces were reconstructed at end-diastole and end-systole in 245 healthy subjects (mean age, 42 ± 12 years) and analyzed using custom software to calculate mean curvature in six regions: RV inflow tract (RVIT) and RV outflow tract, apex, and body (both divided into free wall and septal regions)...

We describe a surgical technique for arthroscopic posterior cruciate ligament (PCL) reconstruction with remnant preservation of the original PCL fibers using a posterior trans-septal portal approach. Using the transtibial technique and the posterior trans-septal portal approach allows good visualization of the tibial tunnel preparation, easy access to the tibial tunnel without neurovascular injury, and preservation of remnant PCL fibers. In the preparation of the tibial tunnel, we expose the PCL tibial attachment site completely, detach the posterior capsule from the PCL, and preserve the distal stump of the PCL without neurovascular injury...

INTRODUCTION: Endoscopic orbital surgery is a nascent field and new tools are required to assist with surgical planning and to ascertain the limits of the tumor resectability. OBJECTIVE: We purpose to utilize three-dimensional radiographic reconstruction to define the theoretical lateral limit of endoscopic resectability of primary orbital tumors and to apply these boundary conditions to surgical cases. METHODS: A three-dimensional orbital model was rendered in 4 representative patients presenting with primary orbital tumors using OsiriX open source imaging software...

Management of the nasal dorsum remains a challenge in rhinoplasty surgery. Currently, the majority of reduction rhinoplasties results in destruction of the keystone area (K-area), which requires reconstruction with either spreader grafts or spreader flaps, both for aesthetic and functional reasons. This article will present the senior author's current operative technique for dorsal preservation in reduction rhinoplasty based on 320 clinical cases performed over a 5-year period. The author's operative technique is as follows: (1) endonasal approach; (2) removal of a septal strip in the subdorsal area whose shape and height were determined preoperatively; (3) complete lateral, transverse, and radix osteotomies; and (4) dorsal reduction utilizing either a push down operation (PDO) or a let down operation (LDO)...

Hypoplastic left heart syndrome (HLHS) encapsulates a spectrum of complex congenital cardiovascular malformations involving varying degrees of underdevelopment of the left-sided heart structures. However, despite improved survival rates since the introduction of staged surgical reconstruction, treatment options for HLHS remain palliative rather than curative. A major limiting factor in the development of definitive curative therapy for HLHS is an incomplete understanding of its pathogenesis. Currently, the aetiology HLHS is best conceptualised by the 'flow theory' of cardiogenesis, which states that normal cardiac development is reliant on the interrelationship of normal flow patterns of blood through the developing heart, and appropriate growth of the cardiac valves and myocardium...

Tension pneumosella (TP) is a rare entity reported as the invagination of the sphenoid sinus mucosa into the skull base after endonasal transsphenoidal surgery. Few studies have reported on TP, and in these studies, invagination is confined to either the intrasellar or suprasellar area. We encountered a case of unexpected prominent TP toward the intracranial space 5 years after endoscopic endonasal transsphenoidal surgery (EETS) for a nonfunctioning pituitary adenoma. In addition, we present a hypothesis of the underlying mechanism by a pressure gradient change between the extracranial and intracranial space in TP formation...

OBJECTIVE: Quadricuspid truncal valves are susceptible to regurgitation, and tricuspid configuration is considered more durable after repairing the truncal valve. We report a new method by excising the excessive truncal cuspid to reconstruct a new competent aortic valve. METHODS: Bilateral pulmonary banding failed to stabilize a 4-month-old baby with type I truncus arteriosus and quadricuspid truncal valve with severe regurgitation, so surgery was performed. The aorta was transected, and the pulmonary arteries was separated from the aorta...

The implantation of autologous cartilage as the gold standard operative procedure for the reconstruction of cartilage defects in the head and neck region unfortunately implicates a variety of negative effects at the donor site. Tissue-engineered cartilage appears to be a promising alternative. However, due to the complex requirements, the optimal material is yet to be determined. As demonstrated previously, decellularized porcine cartilage (DECM) might be a good option to engineer vital cartilage. As the dense structure of DECM limits cellular infiltration, we investigated surface modifications of the scaffolds by carbon dioxide (CO2) and Er:YAG laser application to facilitate the migration of chondrocytes inside the scaffold...

OBJECTIVES/HYPOTHESIS: Endonasal surgeries are the primary cause of septal perforation (SP). However, trauma, inflammation, infections, neoplasms, or abuse of inhaled drugs can also cause SP. Septal repair is indicated in patients who experience nasal obstruction, crusting, intermittent epistaxis, purulent discharge, or nasal whistling and in those who fail conservative treatment. Multiple approaches have been suggested to repair the SP; however, none has been universally adopted. This study explores the feasibility of repairing a total SP using the pericranial flap (PCF)...

The aim of this pictorial review is to describe the technical advances achieved through the application of 4-dimensional (4D) ultrasound using spatiotemporal image correlation (STIC) over conventional 2-dimensional ultrasound in the prenatal detection of congenital heart disease (CHD). Spatiotemporal image correlation is a volume imaging technique that simplifies fetal heart studies while providing more diagnostic information than is typically available from traditional 2-dimensional studies. Four-dimensional software allows the study of cardiac anatomy and function during a single cardiac cycle and has greatly contributed to diagnostic enhancement of CHD...
