SMAS, or Superior Mesenteric Artery Syndrome, is the compression of the 3rd portion of the duodenum between the Abdominal Aorta (AA) and the Superior Mesenteric Artery (SMA). SMAS is also known as Wilkies Syndrome or Cast Syndrome. SMAS can develop naturally or due to traumatic injury. There are other related symptoms and syndromes such Nutcracker Syndrome, Pelvic Varicose Veins, Reverse Peristalsis, Gastroparesis, Gallbladder failure, and Malabsorption Syndrome.. Superior Mesenteric Artery Syndrome is a rare gastro-vascular illness that affects less than .013% of the worlds population.. GARD states: "Researchers have made several estimates of the prevalence rate of SMA syndrome in the population. These estimates have ranged from 0.013% to 0.3% in the general population, which translates roughly to 41,000 to 96,000 Americans with SMA syndrome.[1][2][3] Most of the prevalence rate estimates quoted in recent published articles can be traced back to studies done between 1956-1966.[4][5] Recent ...
Nausea and vomiting in an adolescent, though common presenting symptoms, often pose a diagnostic and therapeutic challenge to the physician. When the diagnosis involves both medical and psychiatric components, management can be complex, especially in the current healthcare system in the United States. To the best of our knowledge, there have been no previous publications detailing successful management of a patient with anorexia nervosa and superior mesenteric artery syndrome. We report the case of a 16-year-old Caucasian girl who presented to our emergency department with nausea, abdominal pain, diminished appetite and vomiting. Her history and examination were notable for a 15 kg weight loss and diffuse abdominal tenderness. A barium swallow X-ray with small bowel follow-through and computed tomography scan demonstrated remarkable duodenal narrowing between the superior mesenteric artery and the aorta, consistent with superior mesenteric artery syndrome. Initial management focused on relieving the
TY - JOUR. T1 - Superior mesenteric artery syndrome in the modern trauma patient. AU - Adams, John B.. AU - Hawkins, Michael L.. AU - Ferdinand, Coville H.. AU - Medeiros, Regina S.. PY - 2007/8/1. Y1 - 2007/8/1. N2 - In 1861, von Rokitansky described obstruction of the third part of the duodenum by external compression of the duodenum by the superior mesenteric artery (SMA). In 1926, this entity was furthermore described by Wilke in his presentation of 75 patients with "chronic duodenal compression". In 1968, Mansberger used angiography to define anatomical measurements as the diagnostic criteria for this condition. Current modalities of diagnosis of SMA syndrome include esophagogastroduodenoscopy, computerized tomography angiogram, fluoroscopy, transabdominal ultrasound, and endoscopic ultrasound. The SMA syndrome has been associated with prolonged confinement in the supine position, loss of weight, loss of abdominal wall muscle tone, application of a body cast, and severe burns. With current ...
Eating disorders are an important cause of physical and psychosocial disturbances. Gastrointestinal complications in eating disorders are common and include pancreatitis and superior mesenteric artery syndrome (SMAS). However, only two patients who simultaneously suffered from both SMAS and pancreatitis in the setting of an eating disorder have ever been reported in the literature. We describe here a patient with eating disorder not otherwise specified (ED-NOS) who exhibited both SMAS and pancreatitis concomitantly. An 11-year-old boy with ED-NOS had presented with the sudden onset of recurrent bilious vomiting, abdominal distension and abdominal pain. Laboratory and imaging studies revealed that the patient had SMAS and acute pancreatitis. Gastric decompression and intravenous infusion of fluids promptly improved his abdominal symptoms and laboratory data. This is the first case report of a patient with ED-NOS who simultaneously suffered from SMAS and pancreatitis in the pediatric literature. Since

Cases of right paraduodenal hernia and superior mesenteric artery syndrome have been reported separately, but their occurrence in combination has not been reported. A 46-year-old Japanese man who had never undergone laparotomy was admitted to our hospital due to an acute abdomen. An enhanced multidetector-row computed tomography scan of our patient showed a cluster of small intestines with ischemic change in his right lateral abdominal cavity. Emergency surgery was subsequently performed, and strangulation of the distal jejunum along with incidental right paraduodenal hernia was found. His necrotic ileum was resected, and the jejunum encapsulated by the sac was repaired manually without reduction. Three days after the operation, however, our patient developed vomiting. An upper gastrointestinal series revealed a straight line cut-off sign on the third portion of his duodenum. A second enhanced multidetector-row computed tomography scan showed that he had a lower aortomesenteric angle and a shorter

Abstract: A well-nourished teen-age girl with psychogenic vomiting demonstrated clinical and radiographic findings of SMAS. Her upper gastrointestinal radiographic studies were normal a few weeks before and three years after the study in which radiographic findings of SMAS were present. Psychologic factors should be considered in SMAS when no condition involving inanition, immobility, abdominal compression, or coexisting abdominal disturbance can be identified ...

The nutcracker syndrome (NCS) results most commonly from the compression of the left renal vein between the abdominal aorta (AA) and superior mesenteric artery (SMA), although other variants exist. The name derives from the fact that, in the sagittal plane and/or transverse plane, the SMA and AA (with some imagination) appear to be a nutcracker crushing a nut (the renal vein). There is a wide spectrum of clinical presentations and diagnostic criteria are not well defined, which frequently results in delayed or incorrect diagnosis. This condition is not to be confused with superior mesenteric artery syndrome, which is the compression of the third portion of the duodenum by the SMA and the AA. Play media NCS is associated with hematuria (which can lead to anemia) and abdominal pain (classically left flank or pelvic pain). Since the left gonadal vein drains via the left renal vein it can also result in left testicular pain in men or left lower quadrant pain in women. Nausea and vomiting can result ...
Superior mesenteric artery syndrome is characterized by the compression of the third segment of duodenum between the aorta and superior mesenteric artery resulting proximal bowel dilatation. In its acute or chronic form, the syndrome is clinically manifest by postprandial epigastric pain, satiety, and vomiting. Etiology may be related to weight loss (loss of fat around the SMA) and/or accelerated vertical growth narrowing the angle between the aorta and SMA.. ...
I have been utterly overwhelmed by the public and private response to the Robert Lerose-conducted interview of me that appeared in Folks magazine here, which has already had over 160 shares from the Folks page alone (and climbing rapidly).. Ive also had scores of questions that have been asked of me about the 60+ surgical procedures Ive had through the years. Without putting my entire medical history online, let me just give a more detailed picture of the effects of Superior Mesenteric Artery Syndrome (SMAS), and the intestinal by-pass surgery that was required in order to save my life. The "blind-loop" or so called "dumping" syndrome that can sometimes result from such a procedure has caused side effects that nobody could have quite predicted. Obviously, I do not regret having had the surgery; I would not be here today to talk about any of this, if I had not had the initial operation at age 14.. But to give a very brief summary of what this has led to, Ill provide a checklist:. o Chronic ...
Anorexia nervosa (a.n.) is a mental disorder connected with the high mortality coming up to 18%. The death causes are suicide and somatic complications resulting from cachexy, laxatives and diuretics abuse, which occurs in some patients and from vomiting provocation. The digestive tract complications are considered to be the death causes in a.n, as well. Among the surgical complications, which usually occur in the initial period of the intensive nutrition the most serious and frequent ones are oesophageal rupture in the course of vomiting provocation (Boerhaaves syndrome) and the syndrome of compression of the horizontal part of the duodenum, by the mesentery (superior mesenteric artery syndrome) leading to the gastrectasia and possible gastric necrosis and perforation. In this paper the review of the current literature concerning the digestive tract complications in a.n. has been made. Also, the courses of the diseases and the complications requiring surgical intervention in 3 patients treated ...

I havent looked at the VIX for a while, but this 3 linear regression study (30,11,3) of the weekly bars gives something to ponder. Given the upslope of the VIX since the beginning of 2007, the 30 bar channel has been a good overbought/oversold tell. Disregarding the current oversold character of the markets, the position of the current VIX bar suggests that increased volatility is the likely trend for the near term. Based on the 3 LRs model, a reversion to the mean would take the VIX to the 27.50 area. . which would translate to a significant decline from current market levels. This concept is at odds with my previous VIX trading methodology which revolved around the VIXs propensity to revert at least 50% back towards the mean within 4 days. . .the mean being the 10 and 20 day SMAs. . when an 18% boundary had been violated. Although that system worked well going into late summer (82% reliable for the IWM)), the August and November performance was rather pitiful as the inverse correlation ...

Chiro.Org Blog: With the important exception of neurologic and vertebral artery syndromes, most of the disorders witnessed in the osterior aspect of the neck are musculoskeletal conditions. Of particular significance are the symptom complexes of cervical arthritis, deformities, disorders of muscle tone, IVD syndromes, spondylosis, vertebral subluxation, tumors, and the effects of trauma. It is helpful to keep in mind that tumors of the cervical spine are usually secondary and that chronic degenerative disc disease and congenital anomalies may be asymptomatic for many years. Functional Considerations Nowhere in the spine is the relationship between the osseous structures and the surrounding neurologic and vascular beds as intimate or subject to disturbance as it is in the neck. Many peripheral nerve symptoms in the shoulder, arm, and hand will find their origin in the brachial plexus and cervical spine. […]. ...

We then test the abilities of the forecast average and individual SMA forecasts to predict monthly SPY returns. Results optimistically assume that an investor can accurately perform calculations just before the monthly close and execute at the same close.. Note that this approach deviates (for simplicity) from that in the referenced study, which uses multiple regressions, rather than averages of single regression outputs, to combine the effects of different SMAs. Use of single regressions assumes that the individual SMAs contribute equally to aggregate predictive power.. The following chart shows the monthly average forecasted SPY return from two-year lagged regressions of all seven SMAs and actual monthly returns for SPY over the available sample period. It appears that there may be some relationship between forecasts and actuals, but forecasts may lag actuals (as expected for SMA and regression calculations).. Why use a two-year regression interval?. ...

Vascular Disturbances A frequent misconception, despite abundant experience to the contrary, is that pain associated with intraabdominal vascular disturbances is sudden and catastrophic in nature. The pain of embolism or thrombosis of the superior mesenteric artery or that of impending rupture of an abdominal aortic aneurysm certainly may be severe and diffuse. Yet, just as frequently, the patient with occlusion of the superior mesenteric artery has only mild continuous diffuse pain for 2 or 3 days before vascular collapse or findings of peritoneal inflammation appear. ...

This report raises the issue of a patient who, despite the preservation of intraoperative mMEPs, emerged from anaesthesia with hemiplegia and mutism. Unexpected postoperative neurological deficits are traumatic to both patients, their family, and the surgical team. In this setting, the ability to predict outcome significantly contributes to the clinical management of these patients. Whenever neuroimaging studies are not conclusive, functional-rather than morphological-evaluation of the integrity of M1/CST using neurophysiological tests could be useful.. Zentner et al 8 described 13 patients who had resective procedures involving the SMA. Despite preservation of mMEPs at the end of surgery in all of them, five patients emerged from anaesthesia with a typical SMA syndrome including hemiplegia contralateral to the resection side. Elicitability of mMEPs was tested early postoperatively using the single magnetic stimulus technique, but mMEPs were not present in the immediate postoperative period and ...

N2 - Introduction: Use of central vascular ligation during dissection around the superior mesenteric artery (SMA) in pancreaticoduodenectomy (PD) for periampullary malignancies has rarely been documented. Methods: We developed the SMA hanging technique (SHT) to facilitate central vascular ligation during PD. Briefly, SMA dissection was initiated using the supracolic anterior approach, followed by left-sided dissection. The SMA was taped under finger guidance immediately after right-sided dissection. The ligament of Treitz was detached from the SMA during left-sided dissection, facilitating adequate lymph node dissection while preserving the nerve plexus around the SMA. ...

DGE after PD is a frequent complication, which is usually managed by nasogastric drainage and nutritional support by parenteral or enteral routes, with or without prokinetics. Many efforts for reducing the incidence of DGE have been attempted; these include pyloric dilation [18], preservation of the left gastric vein [19], preoperative use of erythromycin [20], and prophylactic octreotide [21]. Other studies evaluated the clinical efficacy of reconstruction procedure of gastric emptying. As compared with Billroth II reconstruction, both Roux-en-Y and Billroth-I reconstructions were found to be associated with higher incidence of DGE [22, 23]. Two routes are usually used for Billroth II reconstruction after PD: the antecolic route or the retrocolic route. A meta-analysis reported the superiority of the antecolic route compared with the retrocolic route concerning the reduction of DGE [3]. However, a significant proportion of data in this meta-analysis came from nonrandomized studies, which may ...

Pseudohypertension, also known as pseudohypertension in the elderly, noncompressibility artery syndrome, and Oslers sign of pseudohypertension is a falsely elevated blood pressure reading obtained through sphygmomanometry due to calcification of blood vessels which cannot be compressed. There is normal blood pressure when it is measured from within the artery. This condition however is associated with significant cardiovascular disease risk. Because the stiffened arterial walls of arteriosclerosis do not compress with pressure normally, the blood pressure reading is theoretically higher than the true intra-arterial measurement. To perform the test, one first inflates the blood pressure cuff above systolic pressure to obliterate the radial pulse. One then attempts to palpate the radial artery, a positive test is if it remains palpable as a firm "tube". It occurs frequently in the elderly irrespective of them being hypertensive, and has moderate to modest intraobserver and interobserver ...
1.- Auditory: Stimuli of the transverse gyrus of Heschl of the temporal lobe, may elicit auditory events. Sacks (18) quotes on Dimitri Shostakovich, the Soviet composer, who reportedly had a metallic shell fragment in the temporal horn of his left ventricle. He said since the fragment has been there, each time [I lean] my head to one side, I can hear music - different each time! Apparently he would use this method while composing, producing melodic models for his symphonies. 2.- Vertiginous: Menieres disease is the cause of severe kinesthetic hallucinations , accompanied by nausea, dizziness, and malaise. It may be also have tinnitus, often described as chirping, or as the sound of crickets. This must be clinically differentiated from acoustic neuroma, vertebro-basilar artery syndromes, and other posterior fossa entities. Autoscopic hallucinations: These are a blend of visual and proprioceptive hallucinations. Lhermitte has defined them as the visual hallucination of the self (19). In ...
Acute thrombo-embolic occlusion of the superior mesenteric artery (SMA) with intestinal infarction is a lethal disease, difficult to diagnose in time, with unknown incidence and cause-specific mortality. The aim of this thesis was to characterize the disease and to develop diagnostic methods. Two laboratory studies were conducted on patients with suspected acute SMA occlusion. A pilot-study showed that the fibrinolytic marker D-dimer was elevated in six patients with the disease. In the subsequent study including 101 patients, D-dimer was the only elevated coagulation marker in nine patients with the disease. In a prospective study 24 patients (median age 84 years) were identified, of whom four were diagnosed at autopsy, despite an autopsy-rate of 10%. One-fourth were initially nursed in non-surgical wards. Length of the intestinal infarction was a predictor for death. An analysis of patients from the three studies showed that D-Dimer was elevated in all 16 tested patients with the ...
