Abstract
OBJECTIVES Our goal was to describe a single-center's experience in managing acute and chronic mesenteric ischemia with endovascular therapies. BACKGROUND Open surgical revascularization has been considered the historical gold standard treatment for mesenteric ischemia though it poses considerable morbidity and mortality risk. An aging population with increased comorbidities makes endovascular treatment a more attractive treatment option. METHODS Consecutive subjects receiving percutaneous mesenteric interventions for acute and chronic mesenteric ischemia from 2004 to 2010 were identified retrospectively. Information on comorbidities, symptoms, screening tests, procedural outcomes, and follow up was obtained. RESULTS Thirty-one patients received percutaneous mesenteric interventions during this period. The mean age of the population was 65.0 years with roughly equal proportions of males (48.4%) and females (51.6%). Traditional cardiovascular risk factors were highly prevalent (hypertension 45.2%, diabetes 25.8%, dyslipidemia 38.7%, nicotine use 45.2%). Procedural success was 93.5%; no periprocedural complications were reported. During a mean follow up of 13 months, 16.1% required repeat revascularization and 22.6% died. Endovascular treatment of acute mesenteric ischemia was successful (n = 8) and no patient required open surgical revascularization acutely or during follow-up. CONCLUSIONS Endovascular treatment of mesenteric ischemia is a safe and effective therapy with acceptable long-term results. Our experience with acute mesenteric ischemia suggests that percutaneous treatment may be an effective alternative to surgical revascularization in appropriately selected patients.

Abstract
Intestinal ischemia, or inadequate blood flow to the intestine, is caused by a variety of disorders and conditions. The quickness with which the problem is brought to medical attention for diagnosis and treatment has great effects on the outcome of ischemic injury. Recently, hyperspectral sensors have advanced and emerged as compact imaging tools that can be utilized in medical diagnostics. Hyperspectral imaging provides a powerful tool for noninvasive tissue analyses. In this paper, the hyperspectral camera, with visible and invisible wavelengths, has been evaluated for detection and analysis of intestinal ischemia during surgeries. This technique can help the surgeon to quickly find ischemic tissues. Two cameras, a visible-to-near-infrared camera (400-1000 nm) and an infrared camera (900-1700 nm) were used to capture the hyperspectral images. Vessels supplying an intestinal segment of a pig were clamped to simulate ischemic conditions. A key wavelength range that provides the best differentiation between normal and ischemic intestine was determined from all wavelengths that potentially reduces the amount of data collected in subsequent work. The data were classified using two filters that were designed to discriminate the ischemic intestinal regions.

Abstract
Chronic mesenteric ischemia is primarily a disease of the elderly, who have widespread atherosclerosis of the celiac, superior mesenteric, and inferior mesenteric arteries. Risk factors include smoking, vasculitis, fibromuscular dysplasia, and arterial dissection. Presented here are 2 cases of women under age 50 years burdened with this condition, owing primarily to advanced arteriosclerosis. These cases illustrate a need for increased awareness of mesenteric ischemia as a cause for postprandial abdominal pain in young patients with other stigmata of advanced arterial occlusive disease.

Abstract
PURPOSE To assess the efficacy and durability of percutaneous transluminal angioplasty (PTA)/stent placement for treatment of chronic mesenteric ischemia (CMI). MATERIALS AND METHODS A retrospective review of patients treated from January 1986 to August 2003 was conducted. Twenty-nine patients (mean age, 62 years) were treated for clinical symptoms consistent with CMI. Clinical diagnosis was verified with angiographic assessment and PTA with or without stent placement was performed based on angiographic and/or pressure gradient findings. Outcomes were estimated with the Kaplan-Meier method. RESULTS A total of 63 interventions were performed in 29 patients during the study period. Of these 63 interventions, 46 PTA and 17 stent implantation procedures were performed. Thirty-four interventions were performed for SMA stenosis/occlusion, 17 interventions for celiac artery stenosis/occlusion, and four interventions were performed on aorto-mesenteric graft stenoses. Technical success was 97%, and clinical success (defined as clinical resolution of symptoms) was 90% (26 of 29 patients). Mean duration of follow-up was 28.3 months. Primary patency for all interventions at 3, 6, and 12 months was 82.7% (95% CI: 68.7-96.7), 78.9% (66.7-91.1), and 70.1% (55.1-85.6), respectively. Primary assisted patency for all interventions at 3, 6, and 12 months was 87.9% (79.0-95.3), 87.9% (79.2-95.1), and 87.9% (77.3-98.3), respectively. An average of 1.9 interventions per patient was required. One major complication occurred (3.4%). There were three minor complications (10.3%). CONCLUSIONS Percutaneous intervention for CMI is safe with durable early and midterm clinical success. However, repeated intervention is often required for improved primary assisted patency.

Abstract
Our aging population may result in a rise in the prevalence of chronic mesenteric ischemia. This report reviews our contemporary experience with a tailored surgical approach to chronic mesenteric ischemia. The medical records of 17 patients operated on for chronic mesenteric ischemia were retrospectively reviewed. Symptom-free survival and long-term patency documented by duplex scanning when available were also analyzed. Sixteen patients ranging in age from 32 to 80 years were included in the study. Seventy-five per cent of the patients were female. The most common preoperative complaints were postprandial abdominal pain and weight loss. Revascularization was tailored to the arterial anatomy and included bypass to the superior mesenteric artery (SMA) alone (eight), bypass to the celiac artery and SMA (six), SMA reimplantation onto the aorta (one), SMA/inferior mesenteric artery reimplantation (one), and transaortic endarterectomy of the celiac artery/SMA (one). Bypass conduits included Dacron (eight), saphenous vein (four), and polytetrafluoroethylene (two). Bypass grafts originated from the supraceliac aorta in 12 patients; the remaining bypass originated from the left limb of an aortofemoral graft. There was one perioperative death (mortality 5.6%). Follow-up duplex scans at a mean of 34 months (range 1–114) showed no graft thromboses. We conclude that a variety of surgical techniques can provide durable relief of mesenteric ischemia. A tailored approach to revascularization optimizes patency and provides long-term symptom-free survival.

Abstract
The purpose of this study was to define the place of endovascular treatment in chronic intestinal ischemia (CII). We report here a series of 19 consecutive patients treated with percutaneous angioplasty of the intestinal arteries. We excluded patients with acute ischemia, from the study. From January 1, 1989 to December 31, 2001, 19 patients with symptomatic CII were treated by endovascular techniques. This study group included 11 men and 8 women with a mean age of 59 years (range 30 to 90 years). The clinical presentation included postprandial pain in 16 patients, weight loss in 14 patients, with a mean weight loss of 7.4 kg (range 0 to 30 kg); and gastroparesis in 2 patients. Stenoses were significant in the single superior mesenteric artery (SMA) in 2 patients and in two arteries in 17 patients, including the celiac artery (CA) and SMA (n = 13), CA and inferior mesenteric artery (IMA) (n = 1), and SMA and IMA (n = 3). Balloon angioplasty was performed in only one of the arteries in each patient, 15 times in the SMA and 4 times in the CA. In 7 patients, angioplasty required stenting because of recoil (n = 5) or dissection (n = 1). In one patient the lesion was stented primarily, because of adjacent thrombus on the stenosis. Our results showed that initial treatment of CII can be endovascular. Focus on one artery only, seems to be reasonable and efficient in the short and long term.

Abstract
Major breakthroughs in catheter, guidewire, and other angiographic equipment currently allow interventional radiologists to diagnose massive life-threatening upper and lower GI hemorrhage and to stop the bleeding safely and effectively using superselective catheterization and microcoil embolization. Similarly, the interventional radiologist can treat acute intestinal ischemia safely and effectively with selective catheterization and papaverine administration and treat chronic mesenteric ischemia by percutaneous angioplasty and stent placement. A multidisciplinary approach, including the gastroenterologist, radiologist, and surgeon, is critical in managing GI bleeding and intestinal ischemia, particularly in patients at high risk or presenting as diagnostic dilemmas.

Abstract
Mesenteric arterial diseases are a heterogeneic group of clinically significant illnesses that have become recognized with increasing frequency because of the more common imaging of the intestinal circulation when studying both vascular and nonvascular diseases of the abdomen. Considerable knowledge exists regarding some of these diseases, whereas the understanding of others is anecdotal. It is important for clinicians to recognize differences among common ischemic diseases and common splanchnic aneurysms.

Abstract
Ischaemia of the bowel may arise from a number of causes affecting the arterial and venous compartments of the vascular tree. This article addresses the causes and consequences of arterial obstruction, which may compromise the supply of oxygenated blood to the bowel. These events may occur as an acute phenomenon, or they may present in a chronic fashion. The therapeutic options available to treat this condition are largely dependent on the mode of presentation and the amount of time that is available before irreversible damage occurs to the bowel integrity. In the acute phase, the viability of the bowel is in doubt, and this necessitates an open operative approach to assess the amount of bowel infarction which has already occurred. A variety of operative procedures are then available to limit this bowel loss and to secure the viability of the remaining bowel. In the more chronic phase there are alternative, less invasive procedures that may be appropriate for the patient, who may have suffered a prolonged period of undernourishment and dehydration. In such cases the immediate bowel viability is not in doubt, but the medium/long-term survival is compromised. Treatment options appropriate to each clinical scenario are discussed, along with the major technical issues associated with these treatments. A team approach to the most appropriate management plan is stressed, and the published outcomes reviewed.

Abstract
Chronic splanchnic ischaemia is a relatively unusual clinical entity consisting of pain and/or weight loss and caused by chronic splanchnic disease (i.e. stenosis and/or occlusion of the coeliac and superior mesenteric artery). The occlusive disease is usually caused by atherosclerosis and is in itself not rare in older individuals. Extensive collateral circulation can develop between the three splanchnic arteries and may compensate for the decreased splanchnic perfusion over time. The pathophysiology of chronic splanchnic ischaemia has still not been completely elucidated.A reliable diagnosis of chronic splanchnic ischaemia, based on a proven causal relationship between the occlusive disease and the symptoms, can be very difficult. Traditionally, tests for evaluating the haemodynamic consequences of the vascular stenoses were not available. Important improvements in establishing a more reliable diagnosis have been achieved with duplex ultrasound and magnetic resonance evaluation of the splanchnic circulation. Tonometry is another promising functional test that may prove useful not only for gaining greater insight into the pathophysiology of chronic splanchnic ischaemia but also for the clinical evaluation of this syndrome. The natural history of chronic splanchnic disease suggests that progressive disease may result in acute mesenteric ischaemia. Surgical reconstruction of the coeliac and/or the superior mesenteric artery is the therapeutic standard with excellent short and long-term results. Satisfactory early results using angioplasty with or without stent suggest that this type of intervention may relieve symptoms in selected patients with a higher surgical risk.

Abstract
OBJECTIVE The aim of the study was to evaluate the safety and efficacy of percutaneous angioplasty and stenting (PAS) in comparison with traditional open surgical (OS) revascularization for the treatment of chronic mesenteric ischemia. METHODS Over a 3.5-year period, 28 patients (32 vessels) underwent PAS (balloon angioplasty alone, 5 [18%] of 28; angioplasty and stenting, 23 [82%] of 28) for symptoms of chronic mesenteric ischemia. These patients were compared with a previously published series of 85 patients (130 vessels) treated with OS (bypass grafting, 60 [71%] of 85; transaortic endarterectomy, 19 [22%] of 85; or patch angioplasty, 6 [7%] of 85). RESULTS The PAS and OS groups were similar with respect to baseline comorbidities, duration of symptoms (median: 6.7 vs 10.5 months, P =.52), and the number of vessels involved, but the patients differed in their age at presentation (median: 72 vs 65 years, P =.005). Fewer vessels were revascularized per patient in the PAS group (1.1 +/- 0.4) compared with the OS group (1.5 +/- 0.6, P =.001). Overall, 85.7% (24/28) had one vessel and 14.3% (4/28) had two vessels revascularized in the PAS group versus 48.2% (41/85) with one-vessel and 47.1% (40/85) with two-vessel revascularization in the OS group. No difference was noted in the early in-hospital complications (median: 17.9% [PAS] vs 32.9% [OS], P =.12) or mortality rate (10.7% [PAS] vs 8.2% [OS], P =.71). A reduced length of hospital stay in the PAS patients did not attain statistical significance (median: 5 days [PAS] vs 13 days [OS], P =.08). Although the 3-year cumulative recurrent stenosis (P =.62) and mortality rate (P =.99) did not differ, the PAS treatment group had a higher incidence of recurrent symptoms (P =.001). CONCLUSION Although the results of PAS and OS were similar with respect to morbidity, death, and recurrent stenosis, PAS was associated with a significantly higher incidence of recurrent symptoms. These findings suggest that OS should be preferentially offered to patients deemed fit for open revascularization.

Abstract
PURPOSE The purpose of this study was to determine the safety and efficacy of the elective surgical treatment of symptomatic chronic mesenteric occlusive disease (SCMOD) and to identify the factors that influence the results of this procedure. METHODS From 1977 to 1997, 85 patients (mean age, 62 years) underwent elective surgical treatment of SCMOD. The presenting symptoms were abdominal pain in 78 patients (92%) and weight loss in 74 patients (87%). The surgical procedures included retrograde bypass grafting in 34 patients (40%), antegrade bypass grafting in 24 patients (28%), transaortic endarterectomy in 19 patients (22%), local arterial endarterectomy with patch angioplasty in six patients (7%), thrombectomy alone in one patient (1%), and superior mesenteric artery reimplantation in one patient (1%). Thirty-five patients (41%) underwent concomitant aortic replacement. All the involved mesenteric vessels were revascularized in 21 patients (25%), whereas revascularization was incomplete for the remaining 64 patients (75%). Late information was available for all 85 patients at a mean interval of 4.8 years. RESULTS There were seven early (<35 days) postoperative deaths (8%). The cumulative 5-year survival rate was 64% (95% confidence interval [CI], 53% to 75%), and the 3-year symptom-free survival rate was 81% (95% CI, 72% to 90%). Serious complications occurred in 28 patients (33%). The results of univariate analysis identified advancing age at operation (P <.001), cardiac disease (P =.03), hypertension (P =.03), and additional occlusive disease (P =.05) as variables associated with mortality. Concomitant aortic replacement (P =.037), renal disease (P =.011), advancing age ( P =.035), and complete revascularization ( P =.032) were associated with postoperative morbidity including mortality. Late recurrent mesenteric occlusive disease was seen in 21 patients (16 symptomatic and five asymptomatic). Nine patients (43%) died, and 8 patients (38%) required subsequent surgical or endovascular procedures to treat their recurrent lesions. The 3-year survival rate from recurrent mesenteric occlusive disease was 76% (95% CI, 66% to 86%). CONCLUSION We conclude that the elective surgical treatment of SCMOD may be performed with reasonable early and late mortality rates and that most of the patients remain free from recurrent symptoms of mesenteric ischemia. Advancing age, cardiac disease, hypertension, and additional occlusive disease significantly influenced the overall mortality rates, and concomitant aortic replacement, renal disease, and complete revascularization were significantly associated with postoperative morbidity rates. Surveillance and appropriate correction of recurrent disease appear to be necessary for optimal long-term results.

Abstract
Intestinal ischemia/reperfusion (I/R) is a serious disorder that is prevalent in elderly patients. Reactive oxygen species are implicated in the pathogenesis of intestinal I/R injury. Reactive oxygen species are also implicated in cellular senescence and aging. To test the hypothesis that aging exacerbates intestinal I/R injury, the effects of intestinal I/R on tissue injury were compared between young (3 month old) and aged (12 month old) mice. Intestinal ischemia was induced by occluding the superior mesenteric artery with a microbulldog clamp. Reperfusion was initiated by removing the clamp. Mortality due to intestinal ischemia followed by reperfusion was significantly higher in aged mice. There were no differences in the baseline levels of malondialdehyde or myeloperoxidase activity (indicators of lipid peroxidation and neutrophil infiltration, respectively) between young and aged mice. Although intestinal I/R caused a significant increase in malondialdehyde levels and myeloperoxidase activity in aged mice, similar increases were also observed in young mice. There were no significant differences in the activities of antioxidant enzymes including superoxide dismutase, glutathione peroxidase and catalase between young and aged mice that underwent sham operation. Intestinal I/R caused a significant decrease in catalase activity only in aged mice. In conclusion, our results indicate that aged mice are more susceptible to mortality due to intestinal I/R and that an age-dependent decrease in catalase activity may contribute to the observed mortality.

Abstract
Revascularization for chronic mesenteric ischemia is an infrequent vascular procedure whose objective long-term patency results have been described in relatively few patients. We reviewed our experience with such procedures and report on the objective and symptomatic long-term results. We retrospectively reviewed a consecutive series of 42 patients who underwent mesenteric arterial reconstruction of 66 vessels during an 11-year period from 1986 to 1997. All patients were treated for symptomatic chronic mesenteric ischemia. The results support the clinical efficacy and durability of visceral artery bypass procedures for patients with symptomatic chronic mesenteric ischemia. Patency rates for females were better than for males independent of graft type.

Abstract
Ischemic colitis accounts for approximately half of all cases of mesenteric vasculopathy. The clinical presentation varies depending on underlying cause, extent of vascular obstruction, rapidity of ischemic insult, degree of collateral circulation, and presence of comorbidity. Ischemic colitis is usually diagnosed by colonoscopy. Only approximately 20% of patients require surgery because of signs or laboratory findings of peritonitis or because of clinical deterioration. Approximately 20% of patients develop chronic colitis from irreversible colonic ischemic injury, which manifests clinically as persistent diarrhea, rectal bleeding, or weight loss and endoscopically as a colonic stricture or mass. Chronic mesenteric ischemia is almost always caused by significant atherosclerotic stenosis involving at least two mesenteric arteries, usually the superior mesenteric artery and celiac axis. The classic symptomatic triad of postprandial pain, fear of eating, and involuntary weight loss occurs with advanced disease.

Abstract
PURPOSE Recurrent visceral ischemia after a failed visceral revascularization occurs in up to one third of patients, yet no comprehensive report has described the management of this problem. The purpose of this study was to examine the presentation, surgical management, and outcome of patients with recurrent visceral ischemia. METHODS Between 1959 and 1997, 109 patients underwent primary visceral revascularization at the University of California, San Francisco. Nineteen patients (17.4%) had recurrent visceral ischemia (12 chronic visceral ischemia, seven acute visceral ischemia). Fourteen additional patients with recurrent chronic visceral ischemia were referred after failed primary revascularization (two patients underwent multiple operations before referral). Thirty visceral reoperations were performed for recurrent visceral ischemia in 24 patients (10 patients with recurrence at University of California, San Francisco, 14 referred patients). Symptom-free and overall survival rates were determined by life table analysis. RESULTS Of seven patients (6.4%) who had recurrent acute visceral ischemia, six (85.7%) died of bowel infarction. Twelve patients (11%) had recurrent chronic visceral ischemia. Patients with recurrent chronic visceral ischemia received their diagnoses earlier and lost less weight than at their initial presentation (p = 0.004 and 0.001, respectively). Recurrent ischemia was associated with younger age, greater weight loss, and modification of surgical technique at the time of initial operation (p = 0.5, 0.009, and 0.02, respectively). For 20 (90.9%) of the 22 first reoperations, antegrade aortovisceral bypass (n = 10) or transaortic visceral endarterectomy (n = 10) was used. Multiple techniques (four antegrade bypass, two retrograde bypass, one endarterectomy, one anastomotic revision) were used in the eight second or third reoperations. Postoperative mortality and complication rates were 6.7% and 33.3%, respectively. Symptoms recurred in six of 22 patients (27.3%) after the first reoperation, three of whom were cured or improved after additional reoperations. The life table symptom-free survival rate after reoperation was 77.3% and 62.8% at 1 and 5 years, respectively. The life table overall survival rate after reoperation was 74.6% at 5 years. CONCLUSIONS Recurrent visceral ischemia is not uncommon after primary visceral revascularization. These results show that reoperation for recurrent chronic visceral ischemia can be accomplished safely and effectively with established revascularization techniques. Furthermore, after repeat visceral revascularization patients achieve durable relief of symptoms and have life expectancy rates comparable with those of patients who undergo primary visceral revascularization.

Abstract
Owing to a heightened awareness of the disease as well as improved diagnostic tests, chronic mesenteric ischemia is now recognized as a more common cause of abdominal pain. The classic symptoms of postprandial abdominal pain with weight loss are evident in the majority of proven cases; most patients also have other evidence of advanced atherosclerotic vascular disease. Several new diagnostic techniques are being developed and tested, most notably color duplex imaging, although angiography still remains the diagnostic gold standard. It is hoped that better noninvasive testing may eventually eliminate the need for angiography, as well as lead to a more expedient diagnosis of chronic mesenteric ischemia.

Abstract
Although the technique of endoscopic reflectance spectrophotometry has been applied in clinical studies, factors that modify the reproducibility of measurements have not been assessed systematically. To determine the limitations of the technique, measurements were made while endoscopic light intensity, systemic oxygen saturation, and orientation of the measuring probe were varied. The effects of hemorrhagic hypotension and exposure of the mucosa to 10% dextrose were also studied. When a large number (n = 480) of measurements in the human colon were considered, endoscopic light significantly decreased the index of oxygen saturation (ISO2) and increased the index of hemoglobin concentration (IHB). The decrease in ISO2, however, was small and unlikely to be of clinical importance despite being statistically significant. In one subject with chronic lung disease and baseline hypoxemia, administration of supplemental oxygen significantly increased oxygen saturation at the finger tip as measured by an oximeter and ISO2 of the buccal mucosa as measured by reflectance spectrophotometry. Varying the angle between the measuring probe and the gastric mucosa in rats from 90 degrees to 60 degrees did not affect ISO2 or IHB measurements. At 45 degrees, however, IHB but not ISO2 was significantly increased. Ischemia subsequent to induction of hemorrhagic hypotension and hyperemia induced by administration of 10% dextrose could be demonstrated reproducibly. We conclude that by lowering the intensity of endoscopic light and providing supplemental oxygen, errors in the measurement of IHB and ISO2, respectively, can be minimized. Minor deviations from the perpendicular orientation do not significantly affect ISO2 and IHB measurements. Attention to these details enhances the accuracy of endoscopic reflectance spectrophotometric recordings of ISO2 and IHB in clinical studies.

Abstract
Vascular catastrophe resulting in a bowel infarction requiring massive resection is one of the most common indications for long-term total parenteral nutrition (TPN). The causes of mesenteric artery disease include embolic and thrombotic occlusions, nonocclusive mesenteric ischemia, and chronic mesenteric ischemia. This paper describes a case of a patient with chronic ischemia. The indication for TPN was intestinal angina limiting oral intake, not short-bowel syndrome as a result of bowel infarction and surgery. The patient had an extensive history of atherosclerotic disease and abdominal symptoms. Her nutritional status was maintained with TPN and oral intake as symptomatically tolerated. She eventually developed catheter sepsis. Her cardiopulmonary status deteriorated and she died. Progressive mesenteric ischemia and possible infarction may have contributed to her death. The patient had indicated she did not want surgery for a bowel infarction. She did consent to surgical correction of her disease, if feasible. Although TPN can maintain the nutritional and metabolic status of a patient with chronic mesenteric ischemia, the associated risk of catheter sepsis emphasizes the necessity for expedient treatment of the primary pathology.

Abstract
Complete revascularization for chronic intestinal ischemia is controversial. Fifty-eight patients (119 arteries) underwent mesenteric revascularization between 1981 and 1988. There were 46 women and 12 men (mean age: 63 years). Sixty percent of patients had three-vessel disease. Twenty-one patients underwent concomitant aortic reconstruction. Operative mortality was 10%. Four of the six deaths occurred in patients undergoing aortic surgery. Late graft failure occurred in five patients (10%). Five-year survival for patients with three-vessel involvement who underwent three-vessel repair was 73%, compared with 57% for two-vessel repair and 0% for one-vessel repair (p = NS). Similarly, graft patency in patients with three-vessel disease was highest in those patients who had complete revascularization (90%, 54%, and 0%, respectively) (p = NS). We conclude that increased graft patency and survival in patients with three-vessel disease was most frequent with complete revascularization. Diseased inferior mesenteric arteries should be repaired if feasible. Concomitant aortic operations should be avoided if possible.

Abstract
Angiography is an essential component of the diagnosis and treatment of patients with acute and chronic intestinal ischemia. Aortography and selective angiography permit identification of the cause and precise anatomy of intestinal ischemic syndromes, and also help plan their potential correction. Direct intra-arterial infusion of pharmacologic agents into splanchnic vessels has now become part of the therapy of these conditions. This article reviews angiographic techniques and their applications in the management of intestinal ischemic syndromes.
