Superior mesenteric artery syndrome

F J Bohanon, O Nunez Lopez, B M Graham, L W Griffin, R S Radhakrishnan
Superior mesenteric artery syndrome (SMAS) is a rare, debilitating clinical condition caused by compression of the third portion of the duodenum by the superior mesenteric artery. Common symptoms include intermittent postprandial abdominal pain, nausea, weight loss, and bilious vomiting. Here we present a case series of three patients with SMAS who were treated with laparoscopic duodenojejunostomy. Patients were females between 12-17 years old. All patients underwent a successful laparoscopic duodenojejunostomy after diagnosis...

Triple A syndrome, formerly known as Allgrove syndrome (AS), is characterized by achalasia, alacrima and adrenal insufficiency. Here we report an adolescent male with adrenal insufficiency who developed severe malnutrition secondary to a delayed diagnosis of achalasia. The severe malnutrition in our patient led to superior mesenteric artery (SMA) obstruction syndrome. Severe malnutrition to the point of SMA syndrome has not been previously described in the literature in Triple A syndrome.

Nutcracker syndrome refers to the complex of clinical symptoms caused by the compression of the left renal vein (LRV) between the abdominal aorta and the superior mesenteric artery, leading to stenosis of the aortomesenteric portion of the LRV and dilatation of the distal portion. Hematuria, proteinuria, flank pain, varicocele and pelvic congestion may occur, occurring more frequently in young adults. Conservative management, might be the option whenever it is possible. When surgical treatment is required, classically open surgery have been performed, with major surgeries as LRV transposition or bypass techniques...

The median arcuate ligament (MAL) can rarely compress both the celiac axis and superior mesenteric artery. We present a case of a 70-year male who presented with isolated episodes of upper abdominal pain and diarrhea associated with sweats and nausea. Angiography images demonstrated complete occlusion of the celiac axis and compression of the superior mesenteric artery during the expiration phases. The celiac axis was reconstituted distal to its origin by a patent Arc of Buhler. Other reported cases of multivessel MALs have produced severe symptoms in young adults requiring surgical and/or endovascular intervention...

PURPOSE: Median arcuate ligament syndrome (MALS) is a pathologic entity that can affect the celiac axis. Due to the extensive collateral network of mesenteric circulation, stenosis of one mesenteric artery does not lead to significant symptoms. The purpose of this study was to describe multidetector computed tomography (MDCT) angiography findings of celiac artery entrapment by the median arcuate ligament and determine those patients with high risks of ischemic complications. MATERIALS AND METHODS: From January 2012 to March 2016, 103 patients with celiac artery (CA) compression by median arcuate ligament were detected...

Small bowel obstructions (SBOs) are a known perioperative complication of laparoscopic Roux-en-Y gastric bypass and common etiologies include internal hernia, port site hernia, jejunojejunostomy stricture, ileus and adhesions. Less commonly, SBO can be caused by superior mesenteric artery syndrome, intussusception and intraluminal blood clot. We present a case of SBO caused by intraluminal blood clot from jejunojejunostomy staple line bleeding in a patient with a normal coagulation profile. Computed tomography was used to elucidate the cause of perioperative SBO, and diagnostic laparoscopy was used to both diagnose and treat the complication...

OBJECTIVE: to investigate the pathological physiology of superior mesenteric artery syndrome (SMAS). MATERIAL AND METHODS: We selected 35 articles devoted to SMAS, which were published from 1990 to 2014, and performed radiometric analysis of X-rays, CT scans and MRI slices found in these articles. In pictures the narrowing in the third part of the duodenum was measured from the boundary of the expanded segment to the level of the superior mesenteric artery (SMA)...

Superior mesenteric artery (SMA) syndrome is an uncommon cause of intestinal obstruction and seldom been mentioned in palliative care. Hereby, we reported a case of SMA syndrome who presented with symptoms of upper intestinal obstruction in a 68-year-old patient; subsequent CT findings were classical of SMA syndrome. The patient's history of poliomyelitis and recent significant weight loss were the predisposing factors for SMA syndrome. It also highlights the importance of monitoring signs and symptoms of intestinal obstruction in such patients before considering switching to oral feeding...

Superior Mesenteric Artery (SMA) syndrome is one of the rare cause of proximal small bowel obstruction wherein, the third part of the duodenum is compressed between the SMA at its origin and abdominal aorta due to decreased angulations in these two vessels. This decreased angulation exerts a compression effect on third part of the duodenum, resulting in duodenal obstruction which may be complete or partial. There are number of causes which can lead to this entity and will be discussed briefly. Here we report imaging findings of such a rare cause of proximal small bowel obstruction in a young male patient who presented to the emergency surgical department with non specific symptoms of pain abdomen and abdominal fullness...

Cardiogenic shock (CS) patients treated with ECMO have severe cardiac failure, associated with ischemia-reperfusion. The use of moderate hypothermia during ischemia-reperfusion syndrome is supported by experimental data. We therefore studied the effects of moderate hypothermia on cardiac and vascular function in pig ischemic CS treated with veno-arterial extracorporeal membrane oxygenation (VA-ECMO).Cardiogenic shock was induced in 12 anesthetized pigs by coronary ligation. After one hour of CS, VA-ECMO was initiated and pigs were randomized to normothermia (38°C) or moderate hypothermia (34°C) during 8 hours...

A 48-year-old woman with a history of diabetes was admitted for nausea and vomiting with body weight loss. A blood examination revealed high plasma glucose and thyroid hormone levels and metabolic acidosis. She was therefore diagnosed with both diabetic ketoacidosis (DKA) and hyperthyroidism. Nausea and vomiting continued intermittently despite the administration of saline and insulin. The patient was further diagnosed with superior mesenteric artery syndrome (SMAS) after abdominal computed tomography revealed that a horizontal portion of the duodenum was sandwiched between the aorta and the superior mesenteric artery...

BACKGROUND: Superior mesenteric artery syndrome (SMAS) is a rare condition caused by partial obstruction of the third portion of the duodenum by the SMA anteriorly and aorta posteriorly. Laparoscopic duodenojejunostomy has been described as a safe and feasible surgical intervention with favorable short-term outcomes. However, descriptions of intermediate outcomes are lacking in the literature. METHODS: A retrospective chart review was performed on patients who underwent minimally invasive duodenojejunostomy from March 2005 to August 2015 at our healthcare system with greater than 6-month follow-up...

Background Superior mesenteric artery syndrome (SMAS) results from the compression of the third part of the duodenum between the aorta and the proximal part of the superior mesenteric artery (SMA). Clinical presentation of SMAS is characterized by the dilatation of the proximal part of the third part of the duodenum. SMAS is a rare cause of the upper gastrointestinal system (UGS) obstruction. In this study, we aimed to present our clinical experience in the treatment of five patients with SMAS, which is a rare clinical condition requiring surgery...

PURPOSE: To describe the first case of a patient who developed acute celiac artery compression syndrome (ACACS) after extensive correction of sagittal balance on an adult spinal deformity. METHODS: A 77-year-old woman presented with low back pain and spinal kyphosis deformity. We performed a two-stage correction with extreme lateral interbody fusion (XLIF), and her lumbar lordosis improved from -47° to 53°. However, after surgery, she experienced frequent vomiting and diarrhea...
