OBJECTIVE: To investigate prenatal diagnosis and postnatal outcome of fetuses with crossed ectopic kidney METHODS: Cases referred for an empty renal fossa and diagnosed with crossed ectopic kidney confirmed postnatally were analyzed retrospectively over a period of 10 years. Prenatal diagnosis was established following the detection of one kidney in a normal position, and a second ipsilateral kidney fed by abnormal blood vessels on Doppler flow. RESULTS: Between 2005 and 2015, 185 fetuses were referred for an empty renal fossa...

We describe a case involving a successful Fontan procedure for the treatment of pulmonary arteriovenous fistulas in a patient with polysplenia. The patient was diagnosed with bilateral superior vena cavae, interrupted inferior vena cava with azygos connection, wide separate hepatic veins, and central pulmonary artery stenosis following repair of a non-confluent pulmonary artery. Bilateral extracardiac conduits were used to connect each hepatic vein to the pulmonary artery, opposite each superior vena cava. Clinical improvement in the pulmonary arteriovenous fistulas was observed within 4 months after surgery...

 Background: The Primitive Extratesticular Seminoma is a very rare condition and represents 3% of germ cell tumors; it is an indeterminate origin disease, whose diagnosis is often complicated by a nonspecific and highly variable clinical finding. CASE PRESENTATION: A caucasian 55 years old male, non-smoker, arrived to our centre with cough, severe respiratory distress and dysphagia, in a context of the superior vena cava syndrome. A Computed Tomography was performed, which shows the presence of a mediastinal anterior mass with aorto-pulmonary window and left paracardiac invasion...

INTRODUCTION: Cor triatriatum is a congenital cardiac anomaly in which the left (sinister) or right (dexter) atrium is divided into two compartments by residual embryonic tissue, resulting in a tri-atrial heart. As cor triatriatum dextrum can present clinically in various ways and have multiple associated cardiac anomalies, this report attempts to contribute to what is known about this exceedingly rare disorder. CASE: A 40 year old Hispanic man with a medical history of gastritis presented with complaints of palpitations, dizziness and bilateral lower extremity edema...

Bilateral superior vena cava (SVC) with bilateral partial anomalous pulmonary venous connection is a very rare congenital cardiac malformation. Here, we are reporting a case of 18-year-old male who had bilateral SVC with bilateral anomalous pulmonary venous connection associated with ostium secundum atrial septal defect. The patient underwent successful surgical correction for the same.

The incidence of congenital heart disease requiring specialized care is 2.5 to 3 per 1000 live births with a prevalence of congenital heart disease of 81.4 per 10,000 live births. Total cavopulmonary or atriopulmonary connection, used for palliation of certain types of congenital heart disease, diverts flow from the vena cava or atrium directly into the pulmonary arteries. Altered anatomy in patients who have undergone this intervention may result in contrast and/or radiotracer localizing preferentially to a single lung leading to interpretation errors and redundant studies...

We report the case of an 11-year-old girl with heterotaxy syndrome, dextrocardia, and azygos continuation of an interrupted inferior vena cava who had developed pulmonary arteriovenous fistulas after a Kawashima procedure consisting of bilateral superior cavopulmonary anastomoses. She presented with profound cyanosis, fatigue, and failure to thrive. An operative procedure to direct hepatic vein effluent to the pulmonary circulation was performed with placement of an extracardiac conduit between the hepatic veins and the left pulmonary artery...

An interesting and rare case where a longstanding multinodular goitre causes sudden onset symptoms of superior vena cava obstruction. The symptoms were caused by bilateral brachiocephalic vein compression against the first rib. The patient's symptoms included upper limb and facial swelling, whereas her lower limbs were not oedematous (figure 1). The patient underwent CT imaging which showed a multinodular retrosternal thyroid filling the space created by the first rib, sometimes known as the thoracic outlet...

Staged palliation to achieve a total cavopulmonary connection is a common treatment strategy in patients with single ventricle congenital heart disease. Patients with bilateral superior caval veins (bilateral SVC) often require the creation of bilateral superior cavopulmonary connections as part of the staged palliation, and these patients are at increased risk of morbidity. We describe a novel technique used in two patients with bilateral SVC and very small (1-2 mm) bridging vein that encouraged bridging vein growth and facilitated creation of a unilateral superior cavopulmonary connection...

Peripherally inserted central catheters (PICCs) have been placed through the peripheral veins, and the best location for the tip of the PICCs is the lower third of the superior vena cava (SVC) and cavo-atrial junction. PICCs are commonly used in intravenous administration, parenteral nutrition therapy, chemotherapy, as well as in critical care units. The success rates in venipuncture are enhanced when ultrasonographic guides are used by the bedside PICC teams. There have been few reports of PICCs placed in super elderly patients with permanent cardiac pacemakers...

The purpose of this study was to clarify the recognizable computed tomography (CT) features of small cell lung carcinoma (SCLC).Contrast enhanced CT scans were reviewed retrospectively for mass location, mediastinal extension, and other concomitant findings in 142 patients with pathologically proven SCLC. SCLC was classified into hilar mass only (type I), hilar mass with ipsilateral mediastinal extension (type II), hilar mass with bilateral mediastinal extension (type III), and peripheral mass (type IV). When mediastinal lymphadenopathy (m-LAP) was indistinguishable from a hilar mass, we defined it as a mediastinal conglomerate mass (m-CM)...

Cardiovascular simulations have great potential as a clinical tool for planning and evaluating patient-specific treatment strategies for those suffering from congenital heart diseases, specifically Fontan patients. However, several bottlenecks have delayed wider deployment of the simulations for clinical use; the main obstacle is simulation cost. Currently, time-averaged clinical flow measurements are utilized as numerical boundary conditions (BCs) in order to reduce the computational power and time needed to offer surgical planning within a clinical time frame...

A heart with two atriums but one ventricle, an anatomy with a unique physiology, is responsible for many creative surgical and interventional approaches in history. Different surgical techniques have been used to address this strange physiology of parallel circulation. All these attempts met with failure till the concept of Fontan circulation was described. Currently, controversy exists between multistage vs. single stage total cavopulmonary connections. Total cavopulmonary connection is the only definitive procedure performed to provide palliation for patients with complex congenital heart defects which cannot support a biventricular circulation...

The levoatrial cardinal vein (LACV), first described in 1926, acts as a decompressing vessel for pulmonary venous return in cases of severe left-sided obstruction with an intact or significantly restrictive atrial septum. The LACV and the persistent left superior vena cava (LSVC) are thought to share similar embryologic origins. To challenge this notion, we present a unique case of a neonate with hypoplastic left heart syndrome, cor triatriatum, and a decompressing LACV in the presence of bilateral superior venae cavae...

BACKGROUND: There is a high mortality in infants with right atrial isomerism (RAI). However, less is known about outcome in older children with RAI. This study sought to evaluate those patients with RAI who survived older than 3 years of age without surgical intervention. RESULTS: A total of 33 consecutive patients (20 males) were enrolled in the study, mean age 6 years (range 3-32). None of the patients had surgical intervention for the RAI before age 3. Cardiac abnormalities include altered cardiac position (39 %), atrioventricular valve anomaly (87 %), single or functional single ventricle (55 %), pulmonary/subpulmonary obstruction (97 %), abnormal origin of the aorta (100 %), bilateral superior vena cava (67 %), and anomalous pulmonary venous drainage (66 %)...

Although the optimal treatment strategy for locally advanced thymic carcinomas has yet to be determined, complete resection of the tumor after induction chemoradiotherapy (CRT) can sometimes provide a good chance of being cured. A 61-year-old woman was diagnosed with locally advanced primary thymic carcinoma, which invaded bilateral brachiocephalic veins and superior vena cava with intraluminal tumor thrombus. Induction CRT was performed, and a partial response to the treatment was achieved. Subsequent radical surgery was successfully performed by the median full sternotomy with a right transmanubrial osteomuscular sparing approach (TMA)...

We present a case of sinus venosus atrial septal defect in a patient who was previously diagnosed as having primary pulmonary hypertension in a tertiary care center. Our findings are based on 2-dimensional trans-thoracic echocardiography, chest X-ray and surface electrocardiogram. A 26-year-old man, previously diagnosed as a case of primary pulmonary hypertension, presented to the emergency department (ED) with chest pain and breathlessness on exertion. Cardiac biomarkers were within their normal ranges. Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation...

BACKGROUND: Leiomyosarcoma of vascular origin is a rare tumor, occurring mainly in the inferior vena cava (IVC). When involving the hepatic vein confluence, it often causes Budd-Chiari syndrome, and IVC removal with a complex hepatectomy is required (Mingoli in J Am Coll Surg 211:145-146, 2010; Griffin in J Surg Oncol 34:53-60, 1987; Heaney in Ann Surg 163:237-241, 1966; Fortner in Ann Surg 180:644-652, 1974). METHODS: A 57-year-old male, without previous oncological history, presented with Budd-Chiari syndrome due to a leiomyosarcoma extending to the supra-diaphragmatic IVC and involving the right and middle hepatic veins...

BACKGROUND: Botulinum toxin (BTX), temporarily suppressing cholinergic transmission (<3 weeks), has been reported to suppress atrial fibrillation (AF) for ≥1 year. We aimed to investigate the mechanism underlying long-term suppression of AF caused by injecting BTX into major atrial ganglionated plexi (GPs). METHODS AND RESULTS: Bilateral thoracotomies in anesthetized dogs allowed programmed stimulation at 4 pulmonary veins, biatrial appendages, and the superior vena cava to determine the effective refractory period (ERP) in the first operation...
