Idiopathic azygos vein aneurysm: a rare cause of mediastinal mass. (1/99)

Venous aneurysm of the azygos arch is a very rare cause of mediastinal mass and is usually an incidental finding on chest radiography. Nowadays the diagnosis is made by non-invasive tests such as thoracic CT scanning and/or magnetic resonance imaging. The case is described of an asymptomatic woman in whom a mediastinal mass due to an azygos vein aneurysm was diagnosed by non-invasive procedures, the aetiology of which, in all probability, was idiopathic.  (+info)

Prenatal diagnosis of interrupted inferior vena cava as an isolated finding: a benign vascular malformation. (2/99)

We report two cases of interrupted inferior vena cava with azygous continuation diagnosed as an isolated finding during routine prenatal scans. Visualization of the venous vasculature of the abdomen and thorax in the mid-sagittal plane failed to visualize the segment of the inferior vena cava between the kidneys and the liver. A vessel with venous flow was observed parallel, adjacent and posterior to the aorta between the kidney and the right atrium. This blood vessel connected with the superior vena cava. Axial planes of the thorax confirmed the presence of two vessels running paravertebrally. A detailed ultrasound examination of the fetal anatomy failed to demonstrate other anomalies. The neonatal course of both fetuses was uneventful. Isolated interruption of the inferior uena cava can be a vascular malformation without known pathological consequences.  (+info)

Isolated azygos continuation of the inferior vena cava in the elderly. (3/99)

A 70-year-old woman with the isolated anomaly of azygos continuation of the inferior vena cava is presented. The interest in this anomaly lies in its presentation as a mediastinal mass on the chest roentgenogram. This article reviews the embryogenesis and the diagnostic testing of this venous anomaly.  (+info)

Occlusion of azygos vein via direct percutaneous puncture of innominate vein following cavopulmonary anastomosis. (4/99)

A 2-year-10-month-old boy was diagnosed with a complex congenital heart disease: right atrial isomerism, left superior vena cava (LSVC), complete atrioventricular septal defect, secundum type atrial septal defect, transposition of the great arteries with pulmonary atresia, patent ductus arteriosus, absence of a right superior vena cava (RSVC), and dextrocardia. He had received a left Blalock-Taussig (BT) shunt at the age of 3 months and a left bidirectional Glenn shunt one year after BT shunt. Progressive cyanosis was noted after the second operation and cardiac catheterization showed a functional Glenn shunt with an engorged azygos vein, which was inadvertently skipped for ligation. Because of the absence of RSVC, transcatheter occlusion of the azygos vein was performed successfully via direct puncture of the innominate vein.  (+info)

Giant aneurysm of the azygos anterior cerebral artery--case report. (5/99)

A 77-year-old female presented with a giant aneurysm of the azygos anterior cerebral artery (ACA) manifesting as acute onset of akinetic mutism caused by enlargement of the aneurysm resulting from rapid thrombus formation within the aneurysmal sac. Thrombus removal to obtain decompression of the aneurysmal bulk and tension was performed before parent artery occlusion to prevent thromboembolic events. The aneurysmal neck was completely clipped with preservation of the parent artery and all branches. This strategy for direct neck clipping of a giant thrombosed distal ACA aneurysm can reduce the possibility of ischemic sequelae.  (+info)

Transcatheter coil occlusion of a thoracic arteriovenous fistula in an infant with congestive heart failure. (6/99)

An 8-week-old baby boy presented at our institution with a continuous murmur and congestive heart failure. Echocardiography showed normal cardiac anatomy. Catheterization revealed the presence of a large thoracic arteriovenous fistula between the descending thoracic aorta and the hemiazygous system, with eventual drainage into the azygous vein and the innominate vein. Coil occlusion was performed successfully with a Gianturco coil.  (+info)

Screw-in atrial lead in a sick sinus syndrome patient with anomalous inferior vena cava. (7/99)

Anomalous inferior vena cava without intracardiac anomaly is an unusual condition. Herein, we report a 48-year-old female with left-sided inferior vena cava and azygous continuation. accompanied by sick sinus syndrome. This anomaly resulted in difficulty in implanting a traditional hook-on atrial lead. Atrial lead dislodgment occurred repeatedly soon after implanting the pacemaker because of an anomalous zygous vein draining into the superior vena cava, making a giant connection with the right atrium, thus eliminating the space of the atrial appendage for lead lodgment. Finally, we attempted to utilize a screw-in atrial lead in this patient and she is currently doing well. We therefore suggest that a screw-in atrial lead should be taken into account for such patients in order to obtain a stable fixation.  (+info)

Segmental aplasia of the caudal vena cava in a dog. (8/99)

Ultrasonography, angiography, magnetic resonance imaging, and exploratory laparotomy of a 2-year-old wheaten terrier with lethargy, exercise intolerance, and ascites revealed segmental aplasia of the caudal vena cava with azygos continuation, complicated by thrombus formation. Surgeries were performed on the blind-ended vessel to remove thrombi, enhancing shunting of blood through the azygos vein.  (+info)

N2 - Introduction: The posterior thoracic wall, an area drained by the azygos venous system, is a common site for surgical intervention. Since the venous part of the cardiovascular system is subject to most common variation, abnormalities in the azygos venous system are often reported. Case presentation: During routine dissection classes for undergraduate medical students, we encountered a variation in the azygos venous system in a 65 years old south Indian male cadaver. We observed that there was no accessory azygos vein, and left 4 th, 5th, 6th and 7th posterior intercostal veins terminated directly into azygos vein. Conclusion: Identifying these types of variations is important during ...

A 6 month od baby with Wolfgang-Gollop syndrome was catheterized before surgery for tetralogy of Fallot. Echocardiography had revealed bilateral superior vena cava with LSVC draining into a dilated coronary sinus. In order to assess the need for canulating or ligating the persistent left superior vena cava (LSVC) at time of surgery, we inserted an 5 Fr end-hole catheter into the LSVC via the right atrium and coronary sinus. It was then advanced into the left azygos vein and angiography performed. A large communicating vein connecting the 2 asygos veins was seen beind the heart. Persistent LSVC has been described in tetralogy of Fallot. In our case, although no classical communicating wein could be found by echocardiography, selective angiography revealed a peculiar communication between bilateral azygos veins. The baby underwent successful surgical repair with no need for left superior vena cava cannulation during cardiopulmonary bypass ...
1) S.R.M Medical College, Tamil Nadu.. A.I.M.S, Kochi, Kerala.. One of the major issues raised by the cardiac surgical procedure requiring cardiopulmonary bypass is the question of myocardial protection. Retrograde coronary sinus cardioplegia (RCP) has gained wide spread use as a method of myocardial protection in a broad range of cardiac procedure.. The anatomic variations of the coronary sinus, its orifice in the right atrium and associated persistent left superior vena cava (PLSVC) may affect the distribution of retrograde cardioplegia. PLSVC results in excessive run off of the cardioplegia solution into PLSVC and right atrium, during RCP and leads to maldistribution.. During routine cadaveric dissection, in one male cadaver we found out PLSVC with dilated coronary sinus and the azygos vein on the left side, hemiazygos and accessory hemiazygos veins on the right side.. Embryological basis, clinical implications, sonographic pitfalls, associated congential cardiac anomalies and complications ...

The study is being done to determine if venous angioplasty is an effective treatment for chronic cerebrospinal venous insufficiency (CCSVI). In this condition, areas of narrowing or blockages are present in the internal jugular or azygos veins (veins which drain blood from the central nervous system) and these blockages may be associated with symptoms classically attributed to MS. Therefore, angioplasty may help to improve the symptoms associated with CCSVI and multiple sclerosis (MS). In this study, the investigators will evaluate the effectiveness of angioplasty in the treatment of CCSVI by comparing two the outcomes of two groups of patients: one group with CCSVI diagnosed on a venogram and treated with angioplasty and one group with CCSVI diagnosed on a venogram but not treated. The patients enrolled in this study, and the neurologist evaluating patients after the procedure, will not know whether or not they were treated with angioplasty ...
Six children are reported in whom a central venous catheter from the internal jugular or the subclavian vein migrated to an anomalous position: the left superior intercostal vein in the first two cases, the thymic vein in the third, and the azygos vein in the last three. Resultant complications in five cases were: extravasation of the infusate in the first and third case; local vascular stenosis or complete vascular occlusion in the second and fifth case; and obstruction of the azygos arch due to local thrombosis and possible stenosis, with a likely extravasation of the infusate, in the sixth case. The mediastinal vascular anatomy related to these central venous catheters is reviewed with reference to similar and related cases in the literature.
not to mean any demeanor; but there is no left nor right azygos vein. That why it is called so. http://en.wikipedia.org/wiki/Azygos_vein
A group of researchers in Italy is proposing a revolutionary new theory about Multiple Sclerosis. Theyve offered some compelling evidence that MS is primarily a vascular disease, and that the neurologic damage seen in MS patients has its genesis in blood flow problems within the veins of those patients. Theyre calling this theory Chronic Cerebrospinal Venous Insufficiency, or CCSVI for short.. The Italian researchers, led by Dr. Paolo Zamboni, imaged the veins leading from the brain and spinal cord of several hundred MS patients, and found that virtually all of them showed evidence of a narrowing or blockage of these vital vascular pathways. Specifically, they found blockages or stenosis in the jugular and/or azygos veins of the MS patients they studied, findings not seen in healthy control subjects or in patients with other vascular or neurolgic conditions.. These researchers theorize that these blockages constrict the flow of blood leaving the central nervous system, causing a reflux of ...

Esophageal varices (sometimes spelled oesophageal varices) are extremely dilated sub-mucosal veins in the lower third of the esophagus. They are most often a consequence of portal hypertension, commonly due to cirrhosis; patients with esophageal varices have a strong tendency to develop bleeding. Esophageal varices are typically diagnosed through an esophagogastroduodenoscopy. The upper two thirds of the esophagus are drained via the esophageal veins, which carry deoxygenated blood from the esophagus to the azygos vein, which in turn drains directly into the superior vena cava. These veins have no part in the development of esophageal varices. The lower one third of the esophagus is drained into the superficial veins lining the esophageal mucosa, which drain into the left gastric vein (coronary vein), which in turn drains directly into the portal vein. These superficial veins (normally only approximately 1 mm in diameter) become distended up to 1-2 cm in diameter in association with portal ...

Venous access is obtained from the groin through the femoral vein. The catheter will be advanced into the veins in the neck and chest. Angiographic images will be taken of the extracranial venous system as well as the azygous vein. These images will be used to confirm CCSVI. Venoplasty is performed by inserting an additional catheter with a balloon at the tip. The balloon will be inflated to open the vessel. Once dilation of the vessel is confirmed, the venous sheath will be removed and manual compression applied to the groin access ...
The development of the IVC involves fusion, regression, and establishment of midline anastomoses between parts of three paired fetal venous systems: the two posterior cardinal veins, the two subcardinal, and two supracardinal νeins. The changes in the abdominal venous systems that produce the final IVC cover a long period from day 25 to day 50, mainly between days 29 and 41. Depending on the embryonic origin, four parts of the IVC have been recognized: (1) hepatic segment, (2) prerenal segment, (3) renal segment and, (4) postrenal segment. "Absent IVC" normally designates absence of the prerenal segment of the IVC only, with azygos continuation being the most common variety of an interrupted IVC. "Full IVC agenesis" should cover those cases in which all four parts of the IVC and the iliac venous system are absent and blood return is accomplished by one or both of the following pathways: (1) vertebrolumbar pathway (anterior external vertebral plexus, ascending lumbar veins, and azygos and ...

RADIOLOGY: CHEST: Case# 13: LIPOSARCOMA R SUBCLAVIAN AND SVC. 45 year old male with a history of atrial fibrillation and a one year history of right anterior chest wall pain. Patient recently had a cardiac catheterization which did not show any significant coronary artery disease. There is an abnormal fat collection at the right lung apex that seems to engulf the right subclavian vein and either expands the right brachiocephalic vein or compresses and flattens it. Extensive collaterals are noted around the right shoulder and posterior chest wall with dense opacification of the azygous vein. However, the superior vena cava is patent. Liposarcoma is the second most common soft tissue sarcoma (after malignant fibrous histiocytoma) with the bulk of the tumor differentiating into adipose tissue. This tumor is common in 5-6th decade with 40-50% being myxoid type. These may be painful in 10-15% of cases and more common in the lower extremity (41%) and trunk (42%). The tumor may not be well seen on routine

The computed tomography scan and MRA showed absence of inferior vena cava. Left renal hypoplasia was also noted and a renal perfusion study demonstrated decreased blood flow to this kidney. The right common iliac drained into the azygous vein and the left common iliac drained into hemizygous vein. The deep venous thrombosis (DVT) was initially treated with heparin and then bridged to warfarin, but he only attended follow-up in the clinic intermittently and had a poor medication compliance. After 4 years, a repeat ultrasound showed a subacute left femoral thrombus with persistence of the right iliac thrombus, so he was advised to continue warfarin therapy. Because follow-up and medication compliance proved challenging for this patient, he was offered treatment with a direct oral anticoagulant, rivaroxaban, when he was 25. For the past 3 years, he has been stable with no clinical evidence of a new DVT ...

The post-sinusoidal obstruction to portal flow of alcoholic cirrhosis raises the pressure in the portal system. The pressure is transmitted to the esophageal submucosal veins via the right and left (coronary) gastric, splenic, gastroepiploic and short gastric veins. The connection of the esophageal plexus of veins to the azygous veins in the chest is a natural porta-systemic route of decompression. The bulging esophageal varices are subject to erosion by passing food, resulting in massive bleeding ...
Vasoactive drugs are safe and easy to administer, and universal treatment is the first-line approach for all patients with suspected variceal bleeding. There are strong arguments that the combination of vasoactive drugs, started as soon as possible, and endotherapy later on is the best therapeutic option, particularly in cases of ongoing bleeding at the time of endoscopy. The main action of vasoactive drugs is to reduce variceal pressure. This can be achieved by diminishing the variceal blood flow and/or by increasing resistance to variceal blood flow inside the varices. Changes in variceal pressure parallel changes in portal pressure. Drugs for the treatment of variceal bleeding can therefore be assessed by measuring the changes in portal pressure, azygos blood flow and variceal pressure. Vasoactive drugs can be divided into two categories: terlipressin (Glypressin), and somatostatin and its analogues, especially octreotide. Terlipressin significantly reduces portal and variceal pressure and ...
Biliary atresia in association with laterality malformations - This pattern is also known as Biliary Atresia Splenic Malformation (BASM) or "embryonal" biliary atresia, and occurs 10 to 15 percent of infants with BA. The laterality malformations include situs inversus (reversal of the organs in their natural place), asplenia (no spleen) or polysplenia (multiple misshapen spleen), malrotation, interrupted inferior vena cava, and cardiac anomalies. Data suggest that children with BASM have poorer outcomes compared to those with perinatal BA. ...

The Edinburgh Stereoscopic Atlas of Anatomy. Section-III-No. 24. Thorax. Heart and Pericardium--No. 4. Two specimens viewed from the right side. The specimens have been prepared as described in a pervious view Heart and Pericardium No. 1). The left-hand specimen shown the arrangement of the principal structures in the root of the right lung, and their relation to the superior vena cava, etc. The right bronchus gives off at an early stage, an eparterial branch, which is accompanied by a branch of the pulmonary artery, while the main bronchus passes onwards below the trunk of that artery. The order of structures from above downwards is therefore, eparterial bronchus, right pulmonary artery main bronchus, pulmonary veins. The termination of the vena azygos major is seen passing above the root of the lung. Note also the reflection of serous pericardium from the inferior vena cava. The right hand specimen is viewed more from the front than the other, and shows the unbroken fibrous pericardial bag and ...

The right ventricle receives relatively deoxygenated blood and ejects the majority of its output to the placenta. The left ventricle receives relatively highly oxygenated blood and ejects the majority of its output to the most metabolically active tissues. There are five components of venous return in the fetus: the upper body systemic venous return via the SVC; the lower body systemic venous return via the IVC; the placental return, also via the IVC; the coronary venous return, primarily via the coronary sinus (CS); and the pulmonary venous return via the pulmonary veins. ...
Vascular Clinicians said:. In this series, symptomatology usually was the reason that lead these patients to submit themselves to venous angioplasty, more than a real attitude against traditional medical therapy. The RR Patient group was the relatively easiest one to follow-up since 201 (76%) underwent to only one angioplasty and 63 (24%) to a second one, while none had a third procedure. Firstly, after having clearly identified the presence of CCSVI in a considerable majority of patients affected by MS, there seems to be a frequent parallelism between some disturbs and the vein abnormalities: they usually improve or even disappear when the outflow is corrected.. Secondly, both the clinical and blood flow improvements appear to be long lasting when they are not yet so severe and apparently the neurological damage isn t so widely distributed. This could explain why better and perjuring results appear to occur in the RR group of patients.. ...
Following the liberation therapy, the changes within my body were just as immediate and dramatic as in my first procedure in 2010, hopefully without the fear of re-stenosis; but my headspace almost didnt accept it. The first time with my liberation therapy in the US, the IR found one narrowing in each jugular, the right side being more severe. This time around, two blockages were found on my right side, and again one on the left. I have heard that second and third procedures for venous angioplasty are more difficult for the surgeons because there is more build up of scar tissue in the interior of the veins, but the medical team took their time and did a perfect job. Words cannot express the emotional joy in getting the blood flowing again and getting those symptomatic improvements back a second time!. Four days later I underwent a lower lumbar puncture, but this time not simply to gather information on whether I have MS. This time, stem cells cultured from my own body were on their way to do ...
This is a story quite specific to Canada, but it certainly has global implications.

Absent Inferior Vena Cava (IVC) is an uncommon but well recognised anomaly. Anomalies of the IVC have been described more frequently (0.6%-2%) in those with other cardiovascular defects [2], and less frequently in otherwise healthy individuals. Various anomalies of the IVC have been described including complete absence, partial absence or presence of bilateral IVC [3].. There is controversy as to whether an absent IVC is a true embryonic anomaly or whether it is the result of peri-natal IVC thrombosis causing regression and disappearance of the once present IVC [4].. There has been one previous report in the literature of an absent IVC and left renal hypoplasia- and a right hypertrophic kidney [5]; but a commoner association recognised is right renal aplasia [6] as suggested in a review by Gayer et al, where all nine patients with complete absence of the IVC had an absent or very small right kidney. The association of an absent or hypoplastic kidney is potentially related (or even the cause of ...
Chronic cerebrospinal venous insufficiency (CCSVI or CCVI) is a term developed by Italian researcher Paolo Zamboni in 2008 to describe compromised flow of blood in the veins draining the central nervous system. Zamboni hypothesized that it played a role in the cause or development of multiple sclerosis (MS). Zamboni also devised a procedure which was termed by the media as "liberation procedure" or "liberation therapy", involving venoplasty (or stenting) of certain veins in an attempt to improve blood flow. Within the medical community, both the procedure and CCSVI have been met with skepticism. Zambonis first published research was neither blinded nor did it have a comparison group. Zamboni also did not disclose his financial ties to Esaote, the manufacturer of the ultrasound specifically used in CCSVI diagnosis. The "liberation procedure" has been criticized for possibly resulting in serious complications and deaths while its benefits have not been proven. The United States Food and Drug ...
There has been a great deal of excitment, and rightly so, over the work of Dr. Zamboni and others using venous stents and balloons to open drainage routes of the brain and improve the symptoms of many multiple sclerosis patients. He attributes the cause of MS to chronic cerebrospinal venous insufficiency. The role of venous…
There appears to be no link between chronic cerebrospinal venous insufficiency and multiple sclerosis (MS), according to new research published in CMAJ (Canadian Medical Association Journal).
Inter-rater agreement for CCSVI has never been systematically analysed so far, though scattered information is available from case-control studies. We found an unsatisfactory agreement for the diagnosis of CCSVI with an overall κ of 0.20. For Zambonis five criteria, the agreement was no higher than chance for two criteria (2 and 4), little more than slight for two criteria (3 and 5) and fair for one (criterion 1), according to Landis and Koch s classification.25 Agreement for CCSVI was 0.75 in a study that blindly evaluated 28 participants,19 and 0.79 in another case-control study.11 We found the worst agreement for criteria 2 and 4, whereas it was better for criteria involving a measurement (as for criterion 5) or a direct visualisation of a venous anatomical abnormality (as criterion 3). This seems to indicate that criteria 2 and 4 are more prone to subjective interpretation. Criterion 2 was also the most critical in the study by Tsivgoulis et al,26 together with criterion 5, though their ...

Despite surgical ingenuity to palliate the 1000 infants born annually in the United States with single ventricle (SV) physiology, the predicted life expectancy for these patients remains less than three decades without cardiac transplantation. Shortly after birth, infants undergo the first in a series of operations which ultimately diverts systemic venous return away from the heart, directly into the pulmonary vasculature. Although short and midterm results of this palliation are acceptable, the majority of patients succumb to heart failure. Cardiac transplantation is the optimal treatment; however, due to limited organ supply and an absence of circulatory support strategies, nearly 25% of failing SV patients die while awaiting cardiac transplant ...

Title: Chronic Cerebrospinal Venous Insufficiency (CCSVI) and Multiple Sclerosis (MS): A Critical Review. VOLUME: 10 ISSUE: 6. Author(s):Chiara Zecca and Claudio Gobbi. Affiliation:Servizio di Neurologia e Neuroradiologia, Neurocentro della Svizzera Italiana, Ospedale Regionale di Lugano, via esserete 46, 6903 Lugano, Switzerland.. Keywords:Chronic cerebrospinal venous insufficiency, MRI, Multiple Sclerosis, Pathogenesis, CCSVI, ECD, TCCD, MRI Venography, CCSVI Theory, Doppler sonography. Abstract: Multiple sclerosis (MS) is a chronic disease of the central nervous system with not yet completely understood pathogenesis. The so called "chronic cerebrospinal venous insufficiency (CCSVI) theory" has recently emerged, supporting the concept of a cerebrospinal venous drainage impairment as the cause of MS. Since the first publication on this topic with a claimed 100% specificity and sensitivity of the condition for MS diagnosis, CCSVI theory has generated a scientific and mass media debate with a ...
A five-year-old girl patient was admitted with cyanosis and dyspnea, which started from birth. She had small telangiectatic lesions on her face and cerebral arteriovenous malformation, but no family history of hereditary hemorrhagic telangiectasia. Contrast echocardiography and pulmonary angiography demonstrated diffuse pulmonary arteriovenous fistulas. The patient was diagnosed as polysplenia syndrome characterized with left atrial isomerism, interrupted inferior vena cava, azygous continuation to the superior vena cava, and hepatic veins draining to the right atrium. In contrast to the other polysplenia syndrome cases, in this patient, pulmonary arteriovenous fistulas were not associated with cavopulmonary anastomoses or liver disease.

Introduction. Chylous effusions, particularly chylothorax, are frequently reported in dogs and cats. Chyle is the term used to denote lymphatic fluid arising from the intestine and therefore containing a high quantity of fat. Chyle is normally transported to the venous system by a network of lymphatics in the mesentery (intestinal trunk). These lymphatics arborize in the cisterna chyli, a large dilated sac that lies adjacent to the aorta at L1-L4. The thoracic duct (TD) is the cranial continuation of the cisterna chyli and is generally said to begin between the crura of the diaphragm. In dogs (cats), the thoracic duct lies between the aorta and the azygous vein on the right side (left side) of the thorax and terminates in the venous system of the neck (left external jugular vein or jugulo-subclavian angle). Regardless of the etiology, chylothorax is a potentially devastating disease. Chylothorax results in both compromised respiration and debilitation because of loss of large amounts of ...

We would like to comment on the recently published study entitled "Mystery of Chronic Cerebrospinal Venous Insufficiency: Identical Venographic and Ultrasound Findings in Patients with MS and Controls" by McAuliffe and Kermode.1. The study aimed to analyze a very interesting and controversial topic that recently produced much debate in medical and patients circles. In our opinion, to achieve their goal, the authors used questionable design and methodology, which resulted in numerous limitations of their study.1. Namely, the limited number of the patients and control subjects included makes the whole series inconclusive. Data were missing about the training of actual investigators concerning chronic cerebrospinal venous insufficiency (CCSVI), keeping in mind that the patients examined were their initial 30 cases.1. The authors found internal jugular vein narrowing in 8 of 9 patients without MS by use of venography, but they did not perform sonography (ultrasound) examination before ...

Although user-pay invasive, unregulated procedures are available to those who seek them, this study is the first to describe the prevalence and predictors of one such procedure, the liberation procedure among people with MS. The purpose of this study was to understand why older MS patients chose to have the liberation procedure in order to target and tailor health information for those patients who may be more likely to undertake such interventions. We used a mixed methods approach to secondary data analysis from Canadian national survey data. Using an age, gender and education-matched, case-control algorithm, we created a 3:1 sample of no procedure and procedure. Both groups (with and without the procedure) were on average about 63 years old with 1.5 years of post-secondary education, with women outnumbering men, typical of MS demographics in general (3.48:1 full database; 3.67:1 no procedure: 4.27:1 procedure). Our findings may be applicable to others with chronic disabling ...
Scientific and financial investments in chronic cerebrospinal venous insufficiency (CCSVI) research have been made to address both the hope for and scepticism over this interventional strategy for MS. Despite limited evidence in support of the CCSVI hypothesis, the funding of clinical research was responsive to a demand by the public rarely seen in the history of medicine. We characterize patient perspectives about the CCSVI research trajectory, with particular attention to its impact on other non-pharmaceutical areas of MS research with a focus on stem cell interventions. Semi-structured interviews with 20 MS patients across Canada who did not have CCSVI interventions. Interviews were analysed for recurring themes and individual variations using the constant comparative approach. Participants had a critical view of the divestment of funds from longstanding research to support CCSVI trials. They retain a sense of optimism, however, about emerging evidence for stem cell interventions for MS, and

The authors present a 71-year-old woman who had a right chylothorax after right upper lobectomy for lung cancer. As the chylothorax was considered to be due to thoracic duct injury at the time of operation, lymphoscintigraphy was performed by oral administration of I-123 beta-methyl-iodophenyl pentadecanoic acid (BMIPP). After visualization of the stomach and intestine, abnormal accumulation of the radiotracer was found initially around the right pulmonary hilum and then spread laterally in the upper pleural cavity, indicating chyle leakage in the region of the right pulmonary hilum. Scintigraphic finding was well correlated with the subsequent thoracoscopic observation, showing chyle leakage from a lymphatic tributary near its confluence to the thoracic duct at the level of the azygos continuation. The disruption site was ligated by video-assisted-thoracoscopic-surgery procedure with successful termination of the chyle leakage. Lymphoscintigraphy by oral administration of I-123 BMIPP is thought to be a
Multiple sclerosis is a disease of the brain and spinal cord. An abnormality in the vein that drains blood from the brain and spinal cord may be associated with MS; treating this problem might hold promise as a treatment for MS.
by Physicians Weekly , Dec 28, 2010. The 37th annual Veith Symposium was held from November 17 to 21 in New York City. The features below highlight some of the news emerging from the meeting. Analyzing Different Stenting Approaches for Restenosis The Particulars: Few studies have compared the use of drug-eluting stents after angioplasty with balloon angioplasty and bare-metal stenting in the treatment of restenosis. The Zilver PTX (Cook Medical, Inc.) is the first drug-eluting stent approved for the superficial femoral artery and is currently under investigation in the United States for use in restenosis. Researchers conducted a study comparing the Zilver PTX drug-eluting stent after angioplasty with balloon angioplasty and bare-metal stenting. Data Breakdown: The study enrolled 479 patients at 56 institutions in the United States, Japan, and Germany, with 241 patients randomized to the Zilver PTX group and 238 to the bare-metal stenting group. Demographics and lesion characteristics were ...
CMS released the 2014 Physician Fee Schedule proposed rule this week which contains significant and unexpected reductions in relative values for many endovascular procedure codes. The codes related to dialysis vascular access have all been reduced in value by an approximate average of 10%. This includes commonly used codes: 35475 (arterial angioplasty), 35476 (venous angioplasty), 36870 (thrombectomy) - among others. Indeed, 36147 (angiogram of dialysis access) was reduced by over 30%. It appears that CMS made these drastic cuts in the practice expense or facility calculation and not the physician work component. We are very concerned that these changes could have dramatic impact on the ability of dedicated dialysis vascular access centers to provide patient care since these centers have already been challenged by significant recent cuts in angioplasty and other codes. We are evaluating this just released CMS proposed rule and anticipate responding to CMS during the comment period to argue ...

Often considered a disease which affects adolescents, multiple sclerosis (MS) has been observed in a small percentage of children. Diagnosed before reaching their teenage years, children with MS experience symptoms of a relapsing-remitting course, characterized by defined attacks (relapses) followed by periods of remission. Symptoms of MS are similar in both children and adults; however certain symptoms such as irritability and low-grade fever can be experienced more frequently in children. Children with MS can provide a lot of information on the cause and course of the disease, simply because they are younger and can be observed carefully for initial signs that cannot be examined in an adult with MS. Every day, researchers are learning more about MS from pediatric studies, allowing them to zero in on ways to treat and prevent it. They note that if chronic cerebrospinal venous insufficiency (CCSVI) is a causative factor for MS, it should be evident even in the youngest MS population. As well, ...
A new study published in The Lancet provides the most definitive evidence to date that chronic cerebrospinal venous insufficiency (CCSVI), a hypothetical syndrome of narrowed veins draining the brain that some believe is the true cause of multiple sclerosis (MS), is not associated with MS.

In 24 (0.98%) of 2457 patients with congenital heart disease the brachiocephalic vein was in an anomalous position below the aortic arch. This is a much higher proportion of such cases than reported so far. This high frequency may arise from differences in the study population and the method of diagnosis. This venous anomaly was more common in patients with tetralogy of Fallot or ventricular septal defect with pulmonary atresia. Patients with the venous anomaly were more likely to have a right aortic arch. The anomalous course of the brachiocephalic vein from the neck to the junction of the superior vena cava was shown by cross sectional echocardiography. In doubtful cases, Doppler study usually clarified the anatomical arrangement. ...
We read with interest the letters by Djordje et al and Bavera concerning our article "Mystery of Chronic Cerebrospinal Insufficiency: Identical Venographic and Ultrasound Findings in Patients with MS and Controls." The correspondents noted the relatively small sample size and the fact the patients with MS did not undergo venography as they did not have 2 abnormal criteria. The venographic findings were also not correlated with sonography. All are true, but the important points of the article are inviolate. The starting point of the chronic cerebrospinal venous insufficiency (CCSVI) entity lies on semiobjective nonvalidated sonographic findings1 obtained by operators who are not blinded to the patients condition. This is compounded by a significant trend in the methodology in many articles to consider additional subjective findings of the internal jugular vein valvular appearance as being abnormal. We have indeed cited protocol guidelines that are well-accepted.2 The application of these ...
HOUSTON - Results of a study using several imaging methods showed that CCSVI (chronic cerebrospinal venous insufficiency) occurs at a low rate in both people with multiple sclerosis (MS) and non-MS volunteers, contrary to some previous studies. The research by an interdisciplinary team at The University of Texas Health Science Center at Houston (UTHealth) was published in a recent early online edition of the Annals of Neurology.. "Our results in this phase of the study suggest that findings in the major veins that drain the brain consistent with CCSVI are uncommon in individuals with MS and quite similar to those found in our non-MS volunteers," said Jerry Wolinsky, M.D., principal investigator and the Bartels Family and Opal C. Rankin Professor of Neurology at The UTHealth Medical School. "This makes it very unlikely that CCSVI could be the cause of MS, or contribute in an important manner to how the disease can worsen over time." Wolinsky is also a member of the faculty of The University of ...
Click picture to show/hide bloodflows). Pathophysiology. In the absence of a fully functional left ventricle and/or aortic valve, preservation of systemic circulation and survival is dependent on a patent ductus arteriosus. In this case, the right ventricle takes over for the left to supply the pulmonary and systemic circuits as well as the coronary arteries and brachiocephalic veins (in a retrograde direction). The amount of blood flow to the pulmonary and systemic circulation is a function of the vascular resistance which, in turn, is influenced by the size of the interatrial orifice. Arterial defects that restrict movement cause pressure in the left atrium and pulmonary circuit to increase, and thus restrict pulmonary blood flow. Increased pulmonary blood flow brings a larger volume of oxygenated blood back to the left atrium, which then mixes with the systemic venous return in the right via the foramen ovale.. During the prenatal period all blood, aside from a small volume of pulmonary ...
The purpose of this article is to investigate characteristics of cine phase contrast-calculated cerebrospinal fluid (CSF) flow and velocity measures in patients with relapsing-remitting (RR) multiple sclerosis (MS) receiving standard medical treatment who had been diagnosed with chronic cerebrospinal venous insufficiency (CCSVI) and underwent percutaneous transluminal angioplasty (PTA). This case-controlled, magnetic resonance (MR) imaging-blinded study included 15 patients with RR MS who presented with significant stenoses (,/=50% lumen reduction on catheter venography) in the azygous or internal jugular veins. Eight patients underwent PTA in addition to medical therapy immediately following baseline assessments (case group) and seven had delayed PTA after 6 months of medical therapy alone (control group). CSF flow and velocity measures were quantified over 32 phases of the cardiac cycle by a semiautomated method. Outcomes were compared between groups at baseline and at 6 and 12 months of the ...

One of the major regulators of cerebral venous outflow is posture, due to the gravitational gradient between the cerebral parenchymal veins and the base of the neck (␣30mmHg).2 The authors demonstrate a much larger change in blood flow volume in normal subjects compared to MS patients when the subjects go from a supine to an upright position. They find a change of 128ml/min and 56ml/min for the right and left sides, respectively, for MS patients. But they find a much larger change of 266ml/min and 105ml/min for their normal subjects. This result actually suggests the presence of chronic cerebrospinal venous insufficiency (CCSVI). Possible causes include intra-luminal septum, membrane, and immobile valve affecting the hydrostatic pressure gradient in the upright position. The presence of such blockages in the extracranial and extravertebral cerebral veins has been proven also by using catheter venography, the unquestionable gold standard in medicine.3,4 ...

The persistence of left superior vena cava (PLSVC) is the most common congenital anomaly of the venous return system to the heart. Because of the increasing number of patients referred for cardiac resynchronization therapy (CRT) devices implantations, it is expected to encounter this venous anatomic variation. Left ventricular lead placement at an appropriate site is an integral and technically challenging part of successful CRT. In case of cardiac abnormalities could be difficult to achieve an optimal cardiac rhythm management devices implantation. Previous reports in patients with PLSVC highlighted the challenges to achieve an optimal cardiac rhythm device implantation. Recently, a new quadripolar active fixation left ventricular lead is available for CRT device implantation. Hereby we report a case of a device upgrading from dual-chamber pacemaker to CRT with defibrillator backup using the active fixation left ventricular quadripolar lead in a patient with PLSVC and right superior vena cava atresia.
Dr Massimo Pinzani and colleagues from Italy evaluated the ability of liver stiffness measurement vs hepatic venous pressure gradient to to predict severe portal hypertension.. The research team assessed 61 consecutive patients with Hepatitis C virus-related chronic liver disease.. The researchers found a strong relationship between liver stiffness measurement and hepatic venous pressure gradient measurements in the overall population.. The correlation was excellent for hepatic venous pressure gradient values less than 10 or 12 mm Hg.. However, the team noted that linear regression analysis was not optimal for hepatic venous pressure gradient values 10 mm Hg or 12 mm Hg.. The area under the receiver of operator curve for the prediction of hepatic venous pressure gradient for 10 and 12 mm Hg were 0.99 and 0.92, respectively.. The team noted that at liver stiffness measurement cutoff values of 14 kPa and 18 kPa, sensitivity was 97% and 94%, respectively.. The researchers observed that in patients ...

Therefore, an alternative, non-invasive technique allowing clinicians to diagnose and grade PH in patients with cirrhosis and that could replace HVPG is needed. Transient elastography (TE) has been established as a non-invasive method of measuring liver stiffness due to its diagnostic accuracy in hepatic fibrosis [7]. Accumulating evidence suggests that TE adequately reflects the findings of HVPG, indicating that it is a useful modality for evaluating PH and cirrhotic complications [8-14]. However, some studies have reported conflicting results indicating TE is not sufficiently accurate to replace HVPG due to its insufficient sensitivity or specificity [15]. Hence, controversy remains regarding the usefulness of TE for assessing PH. Systematic reviews (SRs) and meta-analyses (MAs) have facilitated objective evaluation of existing evidence [16-20]. Shi et al. [21] reported the results of their MA for TE in the diagnosis of PH and esophageal varices and further studies should be performed to ...
