Abstract
to characterize the clinical presentation of patients with acute thrombo-embolic occlusion of the superior mesenteric artery (SMA).
prospective study.
twenty-four consecutive patients admitted to Blekinge County Hospital, Karlskrona, Sweden, with acute thrombo-embolic occlusion of the SMA, over a three-year period from April 1999 through March 2002.
clinical data were registered prospectively. Incidence, diagnostic procedures and factors associated with survival were analysed.
the diagnosis was verified at operation in 20, and at autopsy in 4 patients. The incidence was 5.3 per 100 000 inhabitants per year. Among the 20 patients with embolic disease, atrial fibrillation was present in 95%, synchronous embolic events in 30% and warfarin treatment in 10%. D-dimer was elevated on admission in 13/13. Four patients were diagnosed at first consultation. Fifteen underwent curative revascularisation (6) or bowel resection only (9). Five were alive at one-year follow-up, of whom one had short bowel syndrome. Length of bowel ischaemia predicted institutional (p = 0.004) and one-year mortality (p = 0.005).
the incidence was higher than expected. Embolic occlusions predominated. Old age, atrial fibrillation, severe abdominal pain and synchronous embolus suggest the diagnosis of acute bowel ischaemia. Length of bowel ischaemia predicted outcome.

Abstract
To identify risk factors for intestinal ischaemia after aortoiliac surgery.
Among 2824 patients operated on during 1987-93 and registered prospectively in the Swedish Vascular Registry, 62 cases of postoperative intestinal ischaemia were identified. They were compared with the remaining 2762 patients through the registry and with a random sample of 127 controls through patient records. Multivariate analysis was performed.
Patients in shock operated on for ruptured aneurysms were at greatest risk of developing postoperative intestinal ischaemia. Excluding patients in shock, operation for aneurysmal disease and for occlusive disease carried the same risk. Renal disease, emergency surgery, age, type of hospital, aortobifemoral graft, operating time, cross-clamping time and ligation of one or both internal iliac arteries were independent risk factors.
Patient-related haemodynamic risk factors together with surgical skill and decision making defines the risk for this serious complication.

Abstract
To study the incidence and clinical presentation of intestinal ischaemia after aortoiliac/femoral surgery, and to validate a vascular registry concerning a serious complication.
In the Swedish Vascular Registry (SWEDVASC) the outcome and complications of all vascular procedures are registered prospectively.
All 2930 patients operated in 1987-93 were analysed for notified complications. A 5% random sample of all patients and a 20% random sample of fatal cases were analysed for un-notified complications. Of 415 requested patient records 413 were analysed.
The estimated incidence of bowel ischaemia was 2.8%. Among patients operated on for a ruptured aneurysm in shock it was 7.3%. Of the 63 patients with intestinal ischaemia only 15 presented with early passage of bloody stools. In 60 patients (95%) the lesion affected the left colon within the reach of a sigmoidoscope. Bowel ischemia was unnotified only in fatal cases, the estimated un-notified complication rate was 0.7%.
The incidence in this study on unselected patients did not differ from previous reports from specialised centres. Diagnosis is difficult and justifies a high index of suspicion and early use of sigmoidoscopy. The validity of the SWEDVASC registry was confirmed by a high report-rate for this complication.

Abstract
OBJECTIVE To determine the long-term results of above-knee femoro-popliteal bypass with autologous saphenous vein (SV) or expanded polytetrafluoroethylene (ePTFE) in routine surgical practice.
Data from the Swedish vascular registry, Swedvasc, was reviewed retrospectively. Patients with bypass surgery in 1996 and 1997 were assessed 5-7 years later. Data were gathered from the case-records and from clinical follow-up. The composite endpoint of graft failure included death within 30 days, occlusion, major amputation, extension of the graft to below-knee position and removal of an infected graft. Kaplan-Meier curves and Cox' proportional hazard ratios were calculated.
Four hundred and ninety-nine patients undergoing bypass for critical limb ischemia (CLI) (56%) or claudication (44%), SV (28%) or ePTFE (72%), were included. There were no significant differences in patient characteristics between patients with SV or ePTFE. CLI and ePTFE were risk factors for graft failure. For patients with both claudication and CLI SV grafts yielded better long-term results than ePTFE grafts ( p

Abstract
Acquiring contemporary data on prevalence and natural history of abdominal aortic aneurysms (AAA) is essential in the effort to optimise modern screening programmes. The primary aim of this study was to determine the fate of a 65-year-old male population 5 years following an invitation to an aortic ultrasound (US) examination.
In this population-based cohort-study, men were invited to US examination at age 65, and were re-invited at age 70. Mortality, AAA repair, and risk factors were recorded. An AAA was defined as a diameter =30 mm, and a sub-aneurysmal aorta as 25-29 mm.
In 2006-2007, 3,268 65-year-old men were invited, and 2,736 (83.7%) were examined. After 5 years, 24 had completed AAA repair (6 died within 0-4 years), an additional 239 had died, and 194 had moved. Thus, 2,811 70-year-old men were re-invited, and 2,247 (79.9%) were examined. The AAA prevalence increased from 1.5% at 65 to 2.4% (95% CI: 1.8 to 3.0) at 70, and of sub-aneurysmal aortas from 1.7% at 65 to 2.6% (2.0 to 3.3), at 70. Of 2,041 with

Abstract
Nationwide vascular registries offer rapid feed-back in an environment of fast new technical development, as is the case with the treatment of abdominal aortic aneurysm (AAA). Furthermore, they offer an opportunity to study non-selected, population-based data. The aim of this review was to analyze time-trends in published papers from nationwide registries on AAA-repair. In contrast to several US reports, an increased rate of intact AAA repair, associated with the introduction of endovascular repair, was reported in a recent publication based on the Swedish Vascular Registry (Swedvasc). The rate of ruptured abdominal aortic aneurysm (rAAA) repair is stable in most reports, while some report a decreasing incidence. Most nationwide studies report a reducing mortality over time after intact AAA repair, while time trends on the mortality after ruptured AAA repair are more heterogenic.

Abstract
To study external validity of the Swedvasc registry concerning numbers of procedures and mortality.
Vascular registry data for carotid, infrainguinal bypass and aortic aneurysm (AAA) procedures were compared to the Swedish Hospital Discharge Register (SHDR) data, and the National Population Registry (for mortality) by matching every individual patient using the unique personal identity numbers (PINs). The time-period studied was 2000-2004 (5 years) for carotid and infrainguinal procedures. A separate analysis was performed for AAA-surgery in 2006.
The external validity for carotid, infrainguinal bypass and AAA repair was 93.4%, 93.0% and 93.1%, respectively. The 30-day mortality was 0.86% after carotid and 2.9% after infrainguinal bypass procedures. Mortality was 2.6% after planned and 25.9% after unplanned AAA repair. Although there was a general trend towards inferior outcomes after procedures not registered in the Swedvasc, those procedures were so few that in none of the analyses did the inclusion of non-registered procedures affect general outcomes significantly. Combining data from both registries, the incidence for carotid, infrainguinal bypass and AAA procedures was 7.8, 15.2 and 13.6 per 100,000 person-years, respectively. In the hospital-specific analysis for 2006 it was shown that the non-registered procedures for AAA were localized to one non-compliant county hospital, and small district hospitals not performing elective AAA-surgery but only rare emergency operations.
The external and internal validity of the Swedvasc registry allows to confidently assess volumes of, and mortality after, vascular surgery in Sweden.

Abstract
Treatment of abdominal aortic aneurysm (AAA) has changed over time, with endovascular repair (EVAR) being the main technical revolution. This study assessed the effect of this change on outcome on a national basis over a 17-year interval.
Primary infrarenal AAA repairs in Swedish residents aged 50 years and older, in the Swedish Vascular Registry (Swedvasc) 1994-2010, were analysed. The rate per 100,000 population, patient characteristics, operative technique and outcome were assessed for the intervals 1994-1999, 2000-2005 and 2006-2010.
Some 11,336 intact aneurysm repairs were performed. The overall rate per 100,000 increased (18.4 in 1994-1999, 19.4 in 2000-2005 and 24.0 in 2006-2010; P
