In vitro simultaneous measurements of relaxation and nitric oxide concentration in rat superior mesenteric artery. (1/431)

1. The relationship between nitric oxide (NO) concentration measured with an NO-specific microelectrode and endothelium-dependent relaxation was investigated in isolated rat superior mesenteric artery contracted with 1 microM noradrenaline. 2. Acetylcholine (10 microM) induced endothelium-dependent simultaneous increases in luminal NO concentration of 21 +/- 6 nM, and relaxations with pD2 values and maximum of 6.95 +/- 0.32 and 97.5 +/- 0.7 % (n = 7), respectively. An inhibitor of NO synthase, N G-nitro-L-arginine (L-NOARG, 100 microM) inhibited the relaxations and increases in NO concentration induced by acetylcholine. 3. Oxyhaemoglobin (10 microM) reversed the relaxations and increases in NO concentrations induced by acetylcholine, S-nitroso-N-acetylpenicillamine (SNAP) and S-morpholino-sydnonimine (SIN-1), but not the relaxations induced with forskolin. Oxyhaemoglobin also decreased the NO concentration below baseline level. 4. In the presence of L-NOARG (100 microM), a small relaxation to acetylcholine (10 microM) of noradrenaline-contracted segments was still seen; oxyhaemogobin inhibited this relaxation and decreased the NO concentration by 14 +/- 4 nM (n = 4). 5. The NO concentration-relaxation relationship for acetylcholine resembled that for SNAP and SIN-1 more than for authentic NO. Thus while 7-17 nM NO induced half-maximal relaxations in response to SNAP or SIN-1, 378 +/- 129 nM NO (n = 4) was needed for half-maximal relaxation to authentic NO. 6. The present study provides direct evidence that the relaxation of the rat superior mesenteric artery with the endothelium-dependent vasodilator acetylcholine is correlated to the endogeneous release of NO. The study also suggests that NO mediates the L-NOARG-resistant relaxations in this artery, and that there is a basal NO release.  (+info)

Antegrade visceral revascularisation via a thoracoabdominal approach for chronic mesenteric ischaemia. (2/431)

OBJECTIVES: It has been suggested that patients with chronic visceral ischaemia are elderly and emaciated hence they may not tolerate antegrade visceral revascularisation via a thoracoabdominal approach. There are no studies to support this assumption. The purpose of this study is to assess the efficacy of this approach for the treatment of chronic visceral ischaemia. METHODS: Between 1988 and 1996, 10 patients underwent antegrade visceral revascularisation for chronic visceral ischaemia via a thoracoabdominal approach and were followed-up for a mean of 40 months. Eight patients were treated with aorto superior mesenteric artery bypass and implantation of the coeliac axis in the graft and two patients with aorto superior mesenteric bypass alone. Graft patency was monitored with duplex scanning. RESULTS: There were no postoperative deaths in this series. Two patients developed postoperative pulmonary infections and required intubation for a short period of time. All patients were discharged after a mean of 17 days (range 7-38). Follow up with duplex scanning revealed that all grafts were patent. One patient developed a high grade anastomotic stenosis which was followed by recurrence of the symptoms. This was dilated on three occasions by balloon angioplasty within a period of 17 months. On the last occasion a stent was placed and since the patient remains asymptomatic. CONCLUSIONS: Antegrade visceral revascularisation via a thoracoabdominal approach is a durable and effective method of relieving symptoms of chronic visceral ischaemia. The low morbidity in this series justifies larger studies in order to establish the true incidence of complications.  (+info)

Celiomesenteric anomaly with concurrent aneurysm. (3/431)

We describe a rare case of a celiomesenteric anomaly with concurrent aneurysm. The patient, a 53-year-old man, had no abdominal pain or discomfort. The presence of a celiac artery aneurysm was suspected on the basis of the results of abdominal computerized tomographic scanning and echo ultrasound scanning performed because of proteinuria. Intra-arterial digital subtraction angiographic results showed the anomaly and aneurysm. Because of the risk of rupture of the aneurysm, the lesion was repaired surgically, with the placement of an interpositional prosthetic graft. We found no previous reports of celiomesenteric anomaly with concurrent aneurysm repaired with prosthetic graft.  (+info)

NO overproduction by eNOS precedes hyperdynamic splanchnic circulation in portal hypertensive rats. (4/431)

Chronic high blood flow and the hyperdynamic circulatory syndrome in portal hypertension are associated with endothelial constitutive nitric oxide (NO) synthase (eNOS) upregulation and increased NO release. In portal vein-ligated (PVL) rats the splanchnic circulation is not yet hyperdynamic on day 3 postoperatively. In vitro perfused superior mesenteric arteries (SMAs) of day 3 PVL and sham rats were challenged with increasing flow rates or the alpha-adrenoreceptor agonist methoxamine (30 and 100 microM) before and after incubation with the NO inhibitor, Nomega-nitro-L-arginine (L-NNA, 10(-4) M). Perfusate NO metabolite (NOx) concentrations were measured by chemiluminescence. PVL rats expressed a significant hyporesponsiveness to increases in flow rate or methoxamine that was overcome by incubation with L-NNA. The PVL vasculature showed significantly higher slopes of NOx production vs. flow-induced shear stress, higher increases in perfusate NOx concentration in response to methoxamine, and higher eNOS protein levels (Western blot) compared with sham rats. In conclusion, eNOS-upregulation and increased NO release by the SMA endothelium occur before the development of the hyperdynamic splanchnic circulation, suggesting a primary role of NO in the pathogenesis of arterial vasodilatation.  (+info)

Does endothelin-1 reduce superior mesenteric artery blood flow velocity in preterm neonates? (5/431)

AIM: To compare plasma endothelin-1 (ET-1) concentrations in preterm neonates from pre-eclamptic and normal mothers; and to evaluate whether ET-1 has a role in altered arterial blood flow velocity. METHODS: Umbilical arterial blood and neonatal arterial blood were sampled on days 1 and 3 for gas analysis and measurement of plasma ET-1. Doppler ultrasonography of the middle cerebral, renal, and superior mesenteric arteries (SMA) was performed. RESULTS: Neonates in the pre-eclampsia (n = 18) and control (n = 18) groups had mean (SD) gestational ages of 31.1 (2.5) weeks and 30.4 (2.1) weeks; their birth-weights were 1432 (SD 676) g and 1692 (SD 500) g, respectively. In the pre-eclampsia group mean umbilical arterial PO2 was lower--1.88 (0.75) kPa compared with 3.27 (1.41) kPa (p < 0.01)--and mean plasma ET-1 concentration was higher in the umbilical artery--40.6 (SD 15.0) compared with 30.5 (SD 13.8) pg/ml (p = 0.04) and day 1 blood--54.9 (35.0) pg/ml compared with 33.6 (14.6) pg/ml (p = 0.03). Middle cerebral artery peak systolic velocity was higher and SMA time averaged, peak systolic, and mean peak velocities were lower in the pre-eclampsia group. SMA time averaged velocity was inversely related to plasma ET-1 concentration. CONCLUSION: The association between increased production of ET-1 and reduction in SMA time averaged velocity suggests a possible mechanism for hypoperfusion of the intestinal wall in neonates.  (+info)

Effect of caffeine on neonatal splanchnic blood flow. (6/431)

Doppler ultrasound was used to study the effect of the first intravenous dose of caffeine on splanchnic haemodynamics in preterm neonates. Peak systolic velocity in the superior measenteric artery and coeliac axis was significantly reduced for 6 hours after caffeine infusion. The effect of this reduction in blood flow to the neonatal gut is not known.  (+info)

Shear stress-induced nitric oxide antagonizes adenosine effects on intestinal metabolism. (7/431)

The influence of nitric oxide (NO) on adenosine-induced metabolic effects was studied in the intestine. Blood flow supplied an in situ- isolated segment of small intestine in anesthetized cats via the superior mesenteric artery (SMA) and was controlled by a vascular circuit. The SMA and portal samples were taken for analysis of oxygen and lactate. Adenosine (0.4 mg. kg-1. min-1, intra-SMA) reduced oxygen consumption by 25.1 +/- 2.9 from 73.1 +/- 10.8 micromol. min-1. 100 g-1 and increased lactate production by 13.3 +/- 3.0 from 12.8 +/- 4.6 micromol. min-1. 100 g tissue-1 during constant-flow (CF, decreased shear stress) but not during constant-pressure (CP, increased shear stress) perfusion. Blockade of NO synthase using Nomega-nitro-L-arginine methyl ester did not affect the metabolic effects of adenosine during CF but eliminated the differences seen between CP and CF perfusion. A NO donor, 3-morpholinosydnonimine, attenuated the metabolic effects of adenosine during CF perfusion. The results suggested that shear-induced NO antagonized metabolic effects of adenosine but that the inhibition of vascular effects by NO was not shear dependent since it occurred in both CP and CF perfusion.  (+info)

Physiological control of splanchnic blood flow by adrenaline: studies during acute hypoglycaemia in man. (8/431)

Superior mesenteric artery blood flow (SMABF) increases significantly during and after the hypoglycaemia reaction in healthy humans. To investigate the mechanisms controlling this phenomenon, SMABF and plasma catecholamines were measured in healthy human volunteers. In 10 controls, hypoglycaemia was induced by insulin infusion (2.5 m-units.min-1.kg-1). In six subjects, beta-blockade by propranolol infusion (0.7 microgram.min-1.kg-1) preceded insulin infusion and was continued throughout the study. Following the hypoglycaemia reaction, the glucose nadir was similar in both groups. In controls, increases in SMABF [42.4+/-6.1% (mean+/-S.E.M.); P<0. 001], cardiac output (34.3+/-2.3%; P<0.001) and pulse rate (from 63. 9+/-2.7 to 82.5+/-3.1 beats/min; P<0.001) occurred. Superior mesenteric artery resistance fell by 32.4+/-3.3% (P<0.001). Under beta-blockade, decreases in SMABF (34.8+/-2.9%; P<0.001) and pulse rate (from 59.5+/-0.2 to 51.8+/-2.2 beats/min; P<0.001) occurred. Superior mesenteric artery resistance increased (peak +30.8+/-12.3%; not significant). Subjects showed greater increases in adrenaline (P<0.006) and noradrenaline (P<0.022) concentrations than controls. Mesenteric hyperaemia associated with hypoglycaemia in man appears to be mediated by a beta-adrenergic mechanism that is activated by increased circulating levels of adrenaline.  (+info)

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.
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.

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 ...
ABSTRACT: Δ9-tetrahydrocannabinol (THC) produces varying effects in mesenteric arteries: vasorelaxation (third-order branches, G3), modest vasorelaxation (G2), no effect (G1) and vasoconstriction (the superior mesenteric artery, G0). In G3, vasorelaxation to THC was inhibited by pertussis toxin, but was unaffected by the CB1 receptor antagonist, AM251 (1 μm), ... Continue Reading ...
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 ...

Cardiac output, ventral and dorsal aortic blood pressure, heart rate, and coeliac and mesenteric artery blood flow were recorded simultaneously in the Atlantic cod, Gadus morhua L., at rest, during exercise, during hypoxia and after feeding. In the resting unfed animals, coeliac artery blood flow was 4.1 +/− 0.8 ml min-1 kg-1 and mesenteric artery blood flow was 3.5 +/− 1.1 ml min-1 kg-1 (mean +/− S.E.M., N = 10); together, these flows represent approximately 40% of the cardiac output. Exercise or exposure to hypoxia resulted in increased visceral vascular resistance, leading to reductions in the coeliac and mesenteric artery blood flows. Coeliac and mesenteric blood flows were increased 24 h after feeding and the coeliac and systemic vascular resistances decreased in comparison with the prefeeding values. Phentolamine did not affect the gastrointestinal artery blood flow, but produced a significant decrease in the mesenteric and systemic vascular resistance. Treatment with bretylium and ...

Gastric hematoma is a rare disorder. Here we report a case of a large gastric intramural hematoma mimicking an impending rupture of a visceral artery aneurysm. A 60-year-old Japanese woman complained of left flank pain. Computed tomography with intravenously administered contrast agent showed a solid mass of 5 × 5 × 8 centimeter in the left middle abdominal quadrant. On completion of computed tomography, the working diagnosis was an impending rupture of an aneurysm located in a branch of the superior mesenteric artery. Transcatheter arterial embolization was performed, but angiography of the superior mesenteric artery and the inferior mesenteric artery did not indicate extravasation of the contrast agent and we did not observe any aneurysmal structure. We decided to perform surgery. The operational findings revealed that the mass was a gastric intramural hematoma. On encountering an intra-abdominal mass found to be attached to a gastric wall, a gastric intramural hematoma should be considered.
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 ...

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 ...
Objective: Acute mesenteric ischemia (IMA) is a vascular emergency with broad variability of clinical presentations and non-specific laboratory findings. Therefore, there is a significant need for reliable serological markers of ischemia. Various laboratory studies may be performed for suspected AMI, but in general, such studies will not establish the diagnosis.Methods: In a prospective, non-interventional study, from October 2012 to October 2013, we investigated 70 patients with probable diagnosis of AMI. Blood samples were taken from patients and analyzed for complete blood count (CBC), prothrombin time (PT), partial thromboplastin time (PTT), international normalized ratio (INR), urea, creatinine (Cr), sodium (Na), potassium (K), D-dimer, lactate, amylase, PH, partial pressure of carbon dioxide (PCO2), and bicarbonate (HCO3). Finally the results were compared with AMI diagnosis confirmed by computed tomography (CT) angiography.Results: Seventy patients with acute severe abdominal pain were studied.

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 ...

OBJECTIVE. To assess the outcome of surgical (SR) and endovascular (ER) reconstruction for chronic mesenteric ischemia (CMI).. METHODS. Retrospective review of consecutive patients who underwent SR or ER for CMI in 3 UK vascular surgery units between 1996 and 2006. Early (,30 days; technical success, morbidity, mortality, length of hospital stay) and late (,30 days) outcomes (symptom recurrence, vessel/graft patency, reintervention, mortality) were assessed.. RESULTS. A total of 27 patients underwent 32 reconstructions (SR = 17, ER = 15). A total of 44 of 56 (79%) diseased arteries underwent SR (n = 26; bypass = 24, reimplantation = 2; occlusion = 16, stenosis = 10) or ER (n = 18; stenosis = 16, occlusion = 2). Perioperative mortality for SR and ER was 6% and 0%, respectively (P , or = .99). Hospital stay was shorter following ER (mean, 4.3 vs. 14.2 days, P = .0003). Mean (range) follow-up for SR and ER was 34 (1-94) and 34 (0-135) months, respectively. At 2 years, SR demonstrated superior ...

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 ...

Often, the definitive diagnosis of acute mesenteric ischemia cannot be made clinically because of its nonspecific presentation and variable findings on physical examination. However, diffuse abdominal pain out of proportion with other findings should raise suspicion of this diagnosis.1 In stable patients in whom clinical suspicion is high, computed tomography angiography is usually the most appropriate diagnostic test, with a sensitivity and specificity close to 95%.2 However, in patients with peritoneal findings, the diagnosis is usually made with diagnostic laparoscopy3 or laparotomy.4 ...
