BACKGROUND: An anomalous muscle bundle crossing the right atrial cavity represents a pathological finding with unproved clinical significance. This congenital anomaly may be difficult to recognize via echocardiography and could be confused with other intra-cavitary lesions. METHODS: We report a case of a 53-year-old female presented to the cardio-vascular service with acute superior vena cava syndrome and sub-massive pulmonary embolism. RESULTS: The patient underwent venography confirming superior vena cava stenosis...

OBJECTIVE: The aim of this article is to review the postoperative MRI appearances of irreparable massive rotator cuff tears (RCTs) after surgery was performed using newer techniques, including patch repair, muscle tendon transfer, superior capsular reconstruction, and subacromial balloon implantation. CONCLUSION: Newer surgical techniques are emerging for the management of massive RCTs. As radiologists become increasingly likely to encounter postoperative imaging studies of RCTs repaired using these techniques, familiarity with the normal postoperative appearances and complications associated with these techniques becomes important...

PURPOSE: Reconstruction of the anterior cruciate ligament (ACL) is the most frequently performed reconstructive surgery in the knee. Biomechanical studies have shown that double bundle (DB) reconstruction is better than single bundle (SB) reconstruction with regard to rotational stability. It is postulated that resection of ACL fibres that remain in continuity may be counterproductive for the knee as these fibres have the capacity to produce collagen. In this study, we aimed to evaluate the efficacy among selective bundle, DB and SB ACL reconstructions over a 2-year post-operative follow-up period...

There is no consensus regarding the treatment method and outcome of posterior cruciate ligament (PCL) injury. We hypothesized that although the outcome of PCL reconstruction was favorable in terms of knee stability, the outcome was unsatisfactory in terms of patient-based assessments. The purpose of this study is to evaluate the treatment outcomes of knees that underwent reconstruction for PCL injury by subjective and objective assessments, and to analyze the correlation between various assessments. Twenty-three patients who underwent PCL reconstruction were studied...

The anterior cruciate ligament reconstruction (ACLR) has become a very common surgical procedure. One of the main success indicators of the surgical procedure is the return to preinjury sporting level. In recent years, reconstructive techniques have been geared toward less morbidity and optimized ligaments process to speed up the recovery of sports activity. This study compares clinical and imaging data, to evaluate the timing of return to sport, of two populations undergoing ACLR using two different techniques: ACLR with hamstring maintaining tibial insertion (MHG) and an all-inside technique with complete hamstring detachment (DHG)...

Due to advances in neoadjuvant therapies and preoperative imaging modalities, joint-sparing resections have become appealing in bone tumor surgery. However, the intercalary reconstruction of metadiaphyseal bone defects of the femur and the tibia after juxta-articular tumor resection remains challenging. Both biological and prosthetic reconstructions have been used for joint-sparing resections, but little is known about the long-term outcome of these procedures. The authors reviewed a consecutive series of 64 patients treated with joint-sparing intercalary resection and reconstruction with bone grafts...

Craniosynostosis (CS) is defined as the premature fusion of one or more calvarial sutures. This carries several consequences, including abnormal/asymmetric cranial vault development, increased intracranial pressure, compromised neurocognitive development, and craniofacial deformity. Definitive management is surgical with the goal of protecting cerebral development by re-establishing normal cranial vault expansion and correcting cosmetic deformity. In today's practice, CS surgery has advanced radically from simple craniectomies to major cranial vault reconstructive (CVR) procedures...

Cancer is the second most common cause of death in our population just after cardiovascular diseases, since each third individual will become affected by it during their lifetime. Breast cancer is the most common malignancy in women. The lifetime cumulative risk of breast cancer in women under the age of 75 is around 8 % according to Czech statistics. In 70-75 % of all individuals sporadic breast carcinomas are found, with 5-10 % of all women suffer from the hereditary breast and ovarian cancer (HBOC) syndrome...

Anastomotic intraluminal bleeding is a well-known complication after total gastrectomy. Nevertheless, few data are published on acute bleeding obstruction pancreatitis (BOP) due to a bleeding from the jejunojejunostomy (JJ). In this paper we describe our experience. A total of 140 gastrectomies for EGJ cancer were performed in our Institute from January 2012 to January 2017. All reconstructions were performed with a Roux-en-Y anastomosis: a mechanical end-to-side esophago-jejunostomy and a mechanical end-to-side JJ...

INTRODUCTION: The administration of local anaesthetic in the serratus-intercostal space provides adequate analgesia in non-reconstructive breast surgery. The aim of this study was to evaluate whether the blockage of the last intercostal nerves (T7-T11) can lead to opioid savings in supra-umbilical open surgery procedures. MATERIAL AND METHODS: A prospective observational study was conducted on patients undergoing open supra-umbilical surgery under general anaesthesia and with a serratus-intercostal plane block [modified Blocking the bRanches of IntercostaL nerves in the Middle Axillary line (BRILMA)] as an associated analgesic strategy...

BACKGROUND: Langerhans cell histiocytosis (LCH) in adult lumbar spine is extremely rare, and optimal treatments remain unclear. In literature, only a few cases of lumbar spine LCH were treated using surgery but en bloc vertebral resection has not been used. CASE PRESENTATION: A 50-year-old man presented with unbearable radiating pain at his right leg. Radiological studies revealed a solitary osteolytic lesion, which was moderately enhanced on contrast MR imaging and hyper-metabolic on PET/CT, at the right L5 vertebral body and arch...

Parry-Romberg syndrome is a rare neurocutaneous syndrome characterized by progressive shrinkage and degeneration of the tissues usually on only one side of the face. It is usually difficult to restore the facial contour due to skin tightness. In this case report, we report a forehead reconstruction with custom-made three-dimensional (3D) titanium implant of a Parry-Romberg syndrome patient who was treated with multiple fat grafts but had limited effect. A 36-year-old man presented with hemifacial atrophy. The disease progressed from 5 to 16 years old...

Seo Hyung Lee, Yu Jin Kim
BACKGROUND: Skin grafting is a commonly performed operation in plastic and reconstructive surgery. The tie-over dressing is an effective technique to secure the grafted skin by delivering persistent downward pressure. However, if an additional dressing is required due to incomplete graft healing, the process of re-implementing the tie-over dressing may be frustrating for both patients and surgeons. Therefore, we introduce the double tie-over dressing, which readily allows for an additional tie-over dressing after the first dressing, and we present a comparison of its effectiveness with that of the simpler bolster dressing...

INTRODUCTION: Although an uncommon form of admission to a burns centre, the deep, penetrating nature of noxious currents mean that electrical burns have the most catastrophic consequences of all burn injuries. Understanding the physics of electricity is crucial to explaining the mechanisms of tissue damage and organ failure in electrical injuries which necessitate special management above and beyond that of regular thermal burns. PRESENTATION OF CASE: We present a young man who suffered significant occupation-related electrical burns that was complicated by compartment syndrome, rhabdomyolysis and acute kidney injury...
