Typical features of localized arterial dissection with resultant aneurysmal dilatation of the superior mesenteric artery. Both true and false lumens enhance producing a "double barrel" lumen. This lesion seems to have occurred on the basis of underlying atherosclerosis as there is typical intimal calcification in the arterial wall. ...
Retrograde superior mesenteric artery stenting (ROMS) represents a significant development in the treatment of acute mesenteric ischemia. Compared to traditional surgical mesenteric bypass, ROMS is a less invasive technique that avoids many complicat
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 ...
The superior mesenteric artery is a major blood vessel in the digestive system. This artery branches off the abdominal aorta and supplies oxygenated blood to the pancreas and the lower parts of the intestine. This includes the lower duodenum, as well as transverse colon. The artery branches into several other
Glyceryl trinitrate (GTN) is the most commonly used anti-anginal agent, yet its mechanism of action has still to be fully established. Release of nitric oxide (NO) and the selectivity of GTN in the venous system are believed to be crucial to this drugs anti-anginal action. Methods: Rat superior mesenteric arteries and renal veins were mounted in a wire myograph with an intraluminal NO microsensor. Results: In the superior mesenteric arteries, GTN (1 nM to 10 µM) produced a dose-dependent vasodilatation without NO release, except at concentrations supramaximal for relaxation. GTN was found to be markedly less potent in a wide range of veins tested, and lowering the oxygen concentrations in the myograph to that of the venous system did not improve the venodilator activity of GTN. Conclusion: This is the first time that NO release from GTN has been monitored electrochemically in real time, simultaneously with vasodilatation. Unlike the endothelium-dependent vasodilator carbachol, NO could only be ...

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. ...

Sixty-eight patients presented with AMI and 54 underwent PMAS, of which four were unsuccessful and followed by ROMS. Eleven patients were directly treated with ROMS, making a total of 15 patients (10 women and five men; median age, 66 years [interquartile range, 54-73 years]). In all patients, only the superior mesenteric artery was revascularized. In nine of the 15 patients, all three mesenteric arteries were severely stenotic or occluded. Technical success was achieved in 14 patients. At ROMS in two patients, the small bowel was severely ischemic. One of these patients needed a partial bowel resection because of irreversible transmural ischemia. At 30 days, the mortality rate was 20% and the primary patency was 92%. Ten patients underwent unplanned relaparotomy, of whom one needed resection of a large part of the small bowel. At 12 months, the mortality rate was still 20%. The primary patency was 83%. Primary assisted patency was 91%, and secondary patency was 100%. Clinical success at 30 ...
Many methods are used to evaluate ischemia reperfusion injury, but the most employed one is the histological study. However, it only demonstrates on mucosal tunic, the index of lesion and morphologic preserved cells, but not the index of viable functional cells, present in the sample. With this purpose, a colorimetric method was used, employing Methyl Thiazolyl Blue (MTT). The experiment was conducted in 30 Wistar male rats, distributed in 3 groups: Group Control (GC), Group ischemia and reperfusion-1 (GIR-1) and Group ischemia and reperfusion-3 (GIR-3), with 10 animals each. The Groups GIR-1 and GIR-3 were submitted to intestinal ischemia for 30 minutes by a false ligature of superior mesenteric artery, and submitted to euthanasia after 1 and 3 days of reperfusion, when material was picked for absorbency and histological procedures. It was observed a smaller proportion of viable cells and a larger degree of mucosal lesion in GIR-3 group (p,0.05), while GC group was the one with the larger ...

A 54-year-old man with remote large cell non-Hodgkins lymphoma in remission following R-CHOP and severe atopic dermatitis was transferred from another hospital with a non-ST elevation myocardial infarction. Over the preceding year, the patient had suffered recurrent admissions for acutely decompensated heart failure with a newly depressed left ventricular ejection fraction (LVEF) of 20% by echocardiography and rapidly progressive end-stage renal disease of unclear etiology requiring the initiation of hemodialysis. Prior workup had demonstrated an infrarenal abdominal aortic aneurysm and bilateral common iliac artery aneurysms with subsequent computed tomography (CT) additionally demonstrating a superior mesenteric artery aneurysm. The patient was taken for immediate coronary arteriography, which demonstrated giant aneurysms in the left main and right coronary arteries, as well as multivessel severe stenoses. CT coronary angiogram demonstrated significant circumferential wall thickening ...

Acute mesenteric ischemia is a life-threatening condition that can be caused by several different pathologies. Numerous treatment options are available including endovascular intervention and open surgical revascularization. Here we review the most common etiologies of acute mesenteric ischemia and modern treatment options.
TY - JOUR. T1 - Mechanisms of vasorelaxation induced by oleoylethanolamide in the rat small mesenteric artery. AU - Alsuleimani, Yousuf M.. AU - Hiley, C. Robin. PY - 2013/2/28. Y1 - 2013/2/28. N2 - The actions of the anandamide-like mono-unsaturated fatty acid oleoylethanolamide (OEA) were first linked to satiety and control of food intake and recently reported to relax resistance vessels. This study characterizes its vasorelaxant mechanisms. Vasorelaxation to OEA were assessed in third order branches of rat superior mesenteric artery using a wire myograph. The roles of the endothelium, KCa channels, perivascular sensory nerves, NO, cannabinoid receptors, and the phospholipase C (PLC)/inositol trisphosphate (InsP3) and RhoA/ROCK signalling pathways, were assessed. OEA caused concentration- and endothelium-dependent vasorelaxation (pEC50=6.7±0.1, Rmax=93.1±2. 5%). L-NAME greatly reduced the response (residual relaxation of only 24.6±12.8%). Capsaicin and pertussis toxin significantly reduced ...
A 74-year-old hypertensive male presents with a four-hour history of acute-onset severe diffuse abdominal pain. Two weeks prior he was hospitalized with a large anterior wall MI complicated by intermittent atrial fibrillation. Due to a history of frequent falls, he was not anticoagulated. Physical examination is remarkable for an uncomfortable individual with an irregularly irregular heart rhythm and a minimally tender abdomen without peritoneal signs. Laboratory assessment is remarkable for a leukocytosis of 14,000 and mild metabolic acidosis. Electrocardiography indicates atrial fibrillation with a rapid ventricular response between 120 and 140 beats/minute. CT scan of the abdomen illustrates a distended small bowel and a questionable filling defect within the superior mesenteric artery (SMA). Mesenteric arteriography displays a "mercury meniscus sign" within the SMA 4 cm from the aorta. A diagnosis of cardioembolic acute mesenteric ischemia is made and the patient is immediately taken to the ...
VASCULAR SUPPLY AND LYMPHATIC DRAINAGE Arteries The arterial supply of the descending colon is from the inferior mesenteric artery via its left colic branch, which also anastomoses with the marginal artery of the colon (in the region of the splenic flexure), and the sigmoid arteries (in the region of the junction with the sigmoid colon) (Figs 67.29-67.31).

PURPOSE: To present a technique for renal and visceral revascularization allowing complete endovascular treatment of a ruptured type IV thoracoabdominal aneurysm using devices already stocked in most centers performing endovascular aneurysm repair. TECHNIQUE: Open arterial access is obtained to both common femoral arteries and the left subclavian artery (LSA). Access to the visceral and renal arteries is obtained through separate 8-F sheaths for each visceral and renal branch. Both visceral arteries (celiac trunk and superior mesenteric artery) are accessed through 2 separate sheaths placed into the LSA, and both renal arteries are accessed through 2 separate sheaths placed into the left common femoral artery. Corresponding covered stents are introduced and positioned in the celiac trunk, superior mesenteric artery, and both renal arteries but not deployed. The aortic stent-graft is then introduced and deployed through the right common femoral artery. Once the aneurysm exclusion is completed, ...
The goal of treatment for mesenteric ischemia (both chronic and acute) is to re-open the artery to allow adequate blood flow to reach your intestine to allow it to work properly. Because this must be accomplished before permanent damage is done to the bowel, depending on the situation, your vascular surgeon may treat mesenteric ischemia as an emergency or as a scheduled procedure.. For chronic mesenteric ischemia, one treatment method is trans-aortic endarterectomy, which is an operation that removes the plaque that blocks your mesenteric artery. To perform this procedure, a vascular surgeon makes an incision in your abdomen, or side, and then removes the plaque contained in the inner lining of the blocked mesenteric artery. Another treatment option for chronic mesenteric ischemia is bypass surgery. In bypass surgery, the surgeon creates a detour around a narrowed or blocked section of the artery. To create this bypass, your vascular surgeon can use one of your veins or sometimes a tube made ...
A 67-year-old man who presented with a bloody stool was diagnosed with ascending colon cancer. He had previously experienced thoracic and abdominal aortic dissections, which were treated with thoracic and abdominal aortic grafts and superior mesenteric artery revascularization. We performed a laparoscopic right hemicolectomy with a D3 lymph node dissection. During the laparotomy, we identified the superior mesenteric artery and an enlarged anterior superior pancreaticoduodenal artery. Injury to the latter artery could lead to severe ischemia in multiple organs; therefore, it was crucial to identify the primary feeding artery and vascular anatomy before and during surgery ...

Background: Patients with acute mesenteric ischemia (AMI) often exhibit severe co-morbidities and significant surgical risks, leading to high perioperative morbidity. Purpose: To investigate the feasibility of primary percutaneous stent-revascularization (PPSR) in atherosclerotic AMI and its impact on patients outcome. Material and Methods: Retrospective analysis of 19 consecutive patients (7 women, 12 men; median age, 69 years) with AMI caused by atherosclerotic, non-embolic stenoses/occlusions of the splanchnic arteries and PPSR. Alternative minimally invasive techniques were excluded. Clinical characteristics including the Charlson Comorbidity Index adjusted by age (CCIa) and symptom duration, technical and clinical success of PPSR, clinical course, 30-day mortality, and follow-up were evaluated and compared to literature data for surgical approaches. Technical success was defined as residual stenosis of ,30% in diameter. Clinical success was defined as resolution of symptoms of AMI and/or ...

Surgeon-modified retrograde branched extension limb assembling technique and bridged endografts were successfully used to exclude an asymptomatic pararenal abdominal aortic aneurysm and to reconstruct the superior mesenteric artery and bilateral renal arteries in a case with high-grade celiac artery stenosis, nondilated aorta above the superior mesenteric artery, and large lumen below the renal arteries. In patient-specific models for hemodynamics analysis, enhanced flow diversion to visceral arteries up to 6-month follow-up confirmed treatment feasibility; however, endograft configurations could be improved to avoid sharp corners at bifurcations, thereby ensuring smooth flow transport and possibly reducing risk for endograft narrowing or the development of thrombosis ...

The outlook for chronic mesenteric ischemia is good after a successful surgery. However, it is important to make lifestyle changes to prevent hardening of the arteries from getting worse.. People with hardening of the arteries that supply the intestines often have the same problems in blood vessels that supply the heart, brain, kidneys, or legs.. People with acute mesenteric ischemia often do poorly because parts of the intestine may die before surgery can be done. This can be fatal. However, with prompt diagnosis and treatment, acute mesenteric ischemia can be treated successfully. ...

TY - JOUR. T1 - Effects of ambient and stagnant hypoxia on the mechanical and electrical activity of the canine upper jejunum. AU - Meissner, A.. AU - Bowes, K. L.. AU - Sarna, S. K.. PY - 1976. Y1 - 1976. N2 - The effects of ambient and stagnant hypoxia on the mechanical and electrical activity of the upper jejunum were studied in 32 anesthetized dogs. A 50 or 75% reduction in oxygen content of inhaled air produced ambient hypoxia; superior mesenteric artery (SMA) occlusion or thrombin induced mesenteric thrombosis resulted in stagnant hypoxia. Induction of hypoxia was immediately followed by a transient increase in mechanical activity. A 50% reduction in oxygen content had no other effect. A 75% reduction in oxygen content resulted in a gradual decrease in electrical control activity (ECA) frequency and in the disappearance of electrical response activity (ERA), and in jejunal contractions; however, ECA persisted until cardiac arrest occurred after 30 to 45 minutes of hypoxia. Occlusion of the ...
The human bowel receives a significant proportion of cardiac output, which varies with physiologic need. At rest, intestinal perfusion via the superior mesenteric artery will range from 29 to 70mL/min/100g intestinal tissue, whereas in the fed state, splanchnic hyperemia increases perfusion from 28 to 132 percent. Investigation of intestinal perfusion in the setting of chronic inflammation in IBD has been carried out using a variety of in vivo and in vitro techniques. Angiographic studies of the IBD intestine have demonstrated preserved anatomy in the superior and inferior mesenteric arteries, with significant abnormalities in the vasa recta, characterized by tortuous, dilated vessels together with loss of normal tapering and terminal coiling as they penetrate the bowel wall. In early stages of IBD, angio-graphic studies have demonstrated arteries that abruptly taper as the vessels reach the bowel wall with right-angle bifurcation, bizarre distribution, and small luminal irregularities in the ...
Visceral artery disease is the narrowing of the arteries that supply blood to the intestines, spleen and liver. The narrowing is caused by atherosclerosis and results in a reduction in blood flow to these organs. Atherosclerosis is hardening of the arteries due to a build up of plaque, which are fatty deposits that adhere to the artery wall.. The most common presentation of visceral artery disease is chronic mesenteric ischemia, insufficient blood-flow to the intestines. It causes pain after eating and results in weight loss. It can also result in a fatal interruption of blood-flow to the intestines. Without proper flow, the intestines may begin to die and become gangrenous. This condition requires immediate diagnosis and emergency treatment.. The mesenteric arteries supply blood to the large and small intestines. When one or more of the mesenteric arteries narrow or becomes blocked, blood flow is restricted and the intestines fail to get enough oxygen. This is called ischemia - an inadequate ...
In 15 to 20% of patients, the right hepatic artery will arise from the superior mesenteric artery and travel upward toward the liver along the posterior aspect of the head of the pancreas (referred to as a replaced right hepatic artery). It is important to look for this variation on preoperative computed tomographic (CT) scans and in the operating room (OR) so the replaced hepatic artery is recognized and injury is avoided. (See Schwartz 10th ed., p. 1345.) ...
To study whether treatment with heparin (HEP) attenuates intestinal dysfunction caused by ischemia (I) and reperfusion (R), rats were treated with HEP (100 U/kg intravenously) or saline solution (SS) before I (60 min), which was produced by occlusion of the superior mesenteric artery, and R (120 min). After I or I/R, we mounted 2-cm jejunal segment in an organ bath to study neurogenic contractions stimulated by electrical pulses or KCl, using a digital recording system. Thin jejunal slices were stained with hematoxylin and eosin for optical microscopy. Compared with the sham group, jejunal contractions were similar in the I + HEP and the I/R + HEP groups, but reduced in the I + SS and the I/R + SS groups. the jejunal enteric nerves were damaged in the I + SS and the I/R + SS, but not in the I + HEP and the I/R + HEP cohorts. These results suggested that HEP attenuated intestinal dysfunction caused by I and I/R ...
BACKGROUND: To evaluate the appearance of the arrangement of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) on computed tomography (CT) in normal patients and in patients with abdominal masses.. METHODS: One hundred seventy-seven consecutive abdominal CT examinations of 143 adults and two children were reviewed. The relationship of the SMV to the SMA was recorded at four locations: the beginning of the mesenteric vessels and levels 3 cm, 6 cm, and 9 cm caudad to the beginning. The relationship of the SMV to the SMA was divided into four quadrants in relation to the SMA: I, ventral right or directly ventral; II, dorsal right or directly right; III, dorsal left or directly dorsal; and IV, ventral left or directly left.. RESULTS: In the beginning of the SMV-SMA complex and levels 3 cm, 6 cm, and 9 cm caudal to the beginning, the SMV was located in quadrant I in 146, 84, 69, and 43 examinations, in quadrant II in 31, 93, 71, and 27 examinations, in quadrant III in zero, ...

The superior mesenteric artery appeared prominent with a linear filling defect, about 1 cm from its origin and extending up to the origin of the ileocolic artery, representing a dissection with an intimal flap. The false lumen was patent for a short segment, beyond which it was thrombosed. There was focal extension of the intimal flap into the proximal 3rd and 4th jejunal branches. The true lumen appeared normal with no significant compression. Significant fat stranding and cuffing was noted around the SMA. The aorta and the rest of its visceral branches appeared normal except for multifocal areas of atheromatous intimal calcifications in the aorta. No abnormal bowel wall thickening or bowel dilatation was seen ...
Small aortas were documented by CT in six patients, 16-34 years old. The diameter of these aortas measured at the level of 1 cm below the orifice of the superior mesenteric artery ranged from 10 to 12 mm, much smaller than the mean of 17 mm obtained from 20 subjects, 16-20 years old. Such small aortas are usually produced by vasoconstriction as a compensatory response to hypovolemic shock. © 1990 Raven Press, Ltd., New York ...

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 ...
