PURPOSE: Situs inversus totalis is mirror transposition of thoracic and abdominal organs. Very few reports have been published on anatomic dissections of cadavers with this condition. METHODS: This work describes a case of situs inversus totalis identified during the anatomical dissection of a 91-year-old woman. RESULTS: Thoracic and abdominal viscera were inverted, but otherwise normal. The aorta originated from the right ventricle, which exhibited characteristics of the systemic ventricle...

OBJECTIVE: We aimed to evaluate congenital heart disease (CHD) cases according to EUROCAT subgroup classification that were diagnosed during the prenatal period in our center. METHODS: CHDs that were prenatally diagnosed using ultrasonography and confirmed by fetal echocardiography were reviewed over a 10-year period. Subgroup classification was finalized at the post-partum period in terms of the EUROCAT guide 1.3. Congenital heart defect subtypes and obstetric outcomes (gestational week at delivery, birth weight, gender, extracardiac structural abnormalities, karyotype results if performed) were analyzed...

This report presents the case of an 82 year old male with known dextrocardia and situs inversus totalis who developed increasing dyspnea on exertion and was diagnosed with severe aortic stenosis. Transcatheter aortic valve replacement was decided upon requiring deviation from standard techniques for patients with normal anatomy and left-sided aortic arch. We describe two technical differences required for patients with dextrocardia and right-sided aortic arch which facilitate transcatheter aortic valve replacement in this patient group...

A 50-year-old female presented to us with features of obstructive jaundice. Investigations revealed cholelithiasis with single large impacted calculus in the common bile duct (CBD) and significant dilatation of extrahepatic biliary tree. Incidentally, the patient was also detected to have situs inversus totalis (SIT). Attempt at extraction of the calculus in the CBD by endoscopic retrograde cholangiography failed, and a 7F stent was placed. The patient was subjected to laparoscopic cholecystectomy, CBD exploration with the extraction of the offending calculus and laparoscopic choledochoduodenostomy (LCDD)...

Most humans show typical brain functional specialization with language and praxis favoring left hemisphere lateralization and spatial attention and face recognition showing right hemisphere dominance. Lateralization of these cognitive functions was investigated using fMRI in participants with complete visceral reversal and matched control participants. While most participants revealed typical brain organization, atypical functional segregation was significantly more frequent in participants with visceral reversal...

INTRODUCTION: Situs inversus is a rare congenital anomalyin which the thoracic and abdominal organs are sited on the opposite side to that of normal anatomy. Its etiology is still unknown. It is classified into situs inversus partialis and situs inversus totalis. It is discovered incidentally in most cases. Any surgical intervention for such patients may encounter intra-operative technical difficulties due to anatomical differences, particularly if a laparoscopic approach is adopted, as in bariatric surgeries where the obesity itself opposes an added surgical challenge...

Situs inversus totalis (SIT) is a rare congenital anomaly characterized by complete inversion of the thoracic and abdominal organs. Many intra-abdominal and vessel anomalies have been reported in association with SIT. However, there have been no reports on the use of laparoscopic radical nephrectomy with thrombectomy for renal vein thrombus, which is considered as a safe and feasible procedure, in patients with SIT. We herein present the case of an 80-year-old man with SIT who was preoperatively diagnosed with a right renal tumor and renal vein tumor thrombus...

We present the unique case of a 15-month-old male born with biliary atresia and situs inversus totalis and disrupted inferior vena cava who underwent a successful liver transplantation. The patient had previously undergone a failed Kasai procedure and presented with persistent hyperbilirubinemia. The patient was transplanted with a left lateral segment donor having standard arterial anatomy. Technical considerations included identifying completely replaced arterial anatomy in the recipient from the superior mesenteric artery and creating a branch patch between the gastroduodenal artery and HA, anastomosing the donor left hepatic vein to confluences of the donor left, middle, and right hepatic veins, using a "lazy-S" configuration of portal vein anastomosis, and suspending the allograft to the abdominal wall...

Background and study aims  A 72-year-old man with complete situs inversus presented with early gastric cancer on the lesser curvature wall of the antrum of the stomach. Endoscopic submucosal dissection (ESD) was selected as a treatment. When the patient was positioned in the left decubitus position, the lesion was hidden by blood and gastric fluid because it was located on the gravitational side. Therefore, we decided to perform ESD with the patient in the right lateral decubitus position and use an inverted overtube, which provided a good endoscopic view without the need to rearrange the endoscopist, assistants, or endoscopic system...

Situs inversus totalis (SIT) is a rare condition. In this case, a patient who underwent laparoscopic anterior resection for repeated sigmoid colon diverticulitis with SIT was presented. Laparoscopy surgery in patients with this condition has some important technical differences than standard laparoscopic procedures. Therefore, it may be more appropriate to request surgical experience to perform safe laparoscopic surgery in patients with SIT.

Human beings are characterized by a left⁻right asymmetric arrangement of their internal organs, and the heart is the first organ to break symmetry in the developing embryo. Aberrations in normal left⁻right axis determination during embryogenesis lead to a wide spectrum of abnormal internal laterality phenotypes, including situs inversus and heterotaxy . In more than 90% of instances, the latter condition is accompanied by complex and severe cardiovascular malformations. Atrioventricular canal defect and transposition of the great arteries—which are particularly frequent in the setting of heterotaxy —are commonly found in situs solitus with or without genetic syndromes...

Situs inversus totalis considered a malposition syndrome is a very rare condition, occurring in 1 : 8000 births, usually without associated structural congenital heart disease. The diagnosis is often incidental as in this case, which presented with an acute coronary syndrome as a manifestationof multivessel coronary artery disease. Here, we present the challenges encountered during the diagnosis and management of this entity via percutaneous intervention.

Situs inversus totalis (SIT) is a congenital anomaly characterized by a complete mirror-image transposition of the thoracic and abdominal viscera. We report on a rare case of superficial spreading gastric cancer associated with SIT in a 66-year-old woman referred to our hospital for examination of gastric cancer initially diagnosed by medical check-up. Esophagogastroduodenoscopy showed a slightly depressed lesion in the lesser curvature side of the stomach. Abdominal contrast-enhanced computed tomography showed complete transposition of the abdominal viscera, confirming SIT...

We report a case of a 4-week-old female neonate with Jeune's asphyxiating thoracic dystrophy (JATD) and coexistent situs anomaly, primarily presenting as gastric motility disorder. The child presented with abdominal distension and nonbilious vomiting since birth with failure to thrive. However, skeletal survey revealed JATD. Upper gastrointestinal contrast study showed situs inversus with delayed gastric emptying. Pyloric biopsy and intraoperative antro-duodenal manometry confirmed association of gastric motility disorder...

Situs inversus totalis (SIT) is a rare anomaly. A limited number of reports document surgery for lung cancer in patients with SIT. We report the case of a 68-year-old man with SIT who underwent video-assisted thoracoscopic bisegmentectomies for synchronous double primary lung cancers. Preoperative evaluation of the pulmonary vessels and bronchus by three-dimensional computed tomography (CT) was unavailable owing to the patient's renal function disorder. However, the procedure was safely completed by adequate anatomic identification and careful operative manipulation based on plain CT study...

BACKGROUND Poorly controlled ventricular rate associated with atrial fibrillation (AF) leads to tachycardia-induced left ventricular dysfunction. Atrioventricular (AV) nodal ablation and cardiac pacing is the standard of care in refractory congestive heart failure (CHF) due to AF with moderate to rapid ventricular response that failed conventional medical therapy. If the patient is not a candidate for AF ablation with pulmonary vein isolation and elimination of AF foci, this is an effective approach, but it does have some challenges when done in a patient with dextrocardia and situs inversus...

Martin Blum, Tim Ott
Symmetry is appealing, be it in architecture, art or facial expression, where symmetry is a key feature to finding someone attractive or not. Yet, asymmetries are widespread in nature, not as an erroneous deviation from the norm but as a way to adapt to the prevailing environmental conditions at a time. Asymmetries in many cases are actively selected for: they might well have increased the evolutionary fitness of a species. Even many single-celled organisms are built asymmetrically, such as the pear-shaped ciliate Paramecium, which may depend on its asymmetry to navigate towards the oxygen-richer surface of turbid waters, at least based on modeling...

Polysplenia syndrome is a rare condition (about 2.5:100,000 live births) wherein a person has two or more spleens with accompanying various thoracic and abdominal organ abnormalities. Polysplenia is usually associated with situs ambiguous, while polysplenia with situs inversus is very rare. Herein, we report a rare case of incidentally found polysplenia syndrome combined with situs inversus in a 59-year-old female who also had an interrupted inferior vena cava (IVC) with azygos continuation, patent ductus arteriosus (PDA), and variations in the aortic arch branches...
