Abstract

An abdominal aortic aneurysm (AAA) is a dangerous condition characterized by an abnormal dilation of the abdominal aorta (a major artery), usually reflecting a structural weakness in the wall of the vessel. Rupture of the AAA can be fatal due to massive hemorrhage. Inflammatory aneurysms of the abdominal aorta (IAAA) are characterized by inflammation and extensive fibrous (scar-like) tissue growth causing adhesion to surrounding organs, making surgical isolation of the aneurysm extremely difficult. In cases where the standard operative approach (through the abdomen) has been used in treating IAAAs, the incidence of damage to adjacent organs ranged between 5 and 15 percent of the cases. A new and highly successful approach, accessing the aneurysm from the back (extraperitoneal approach), is much less risky than the standard approach. In a series of 45 patients treated for IAAA over the past 12 years, the results for patients operated on by the standard abdominal approach have been much bleaker than when the extraperitoneal approach has been used. Of 41 patients undergoing standard approach treatments, over 15 percent suffered significant complications during and after surgery, including heart attack, kidney failure, and loss of blood supply to the gastrointestinal tract. Three patients had died within 30 days of surgery (7.7 percent mortality). In four patients treated with the extraperitoneal method, there were no significant complications and no deaths. Computerized tomographic (CT) visualization of IAAA in 12 patients revealed that there was significantly more fibrosis (scar tissue formation) on the anterior wall of the aneurysm (the route of the abdominal approach) than the left posterolateral wall (route of the extraperitoneal approach).

Abstract

One other advantage of the single-vendor approach is the availability of pre-verified hardware/software platform combinations, not only for delivering functionality but also providing a path for users to meet the IEC 624433-3 cybersecurity standard. Greater than the sum of the parts Developers have a lot of hardware and software options for building industrial automation, visualization and data connectivity/analytics projects.

Abstract

The infection of a prosthetic vascular graft (PVGI), although rare, is the most severe complication in reconstructive vascular surgery. The early diagnosis of this complication reduces the death rate from surgery. Aortofemoral graft infections differ clinically from peripheral graft infections in significant ways. The aim of this article is to evaluate separately the reliability of the 99mTc-HMPAO-labeled leukocyte scan or white blood cell count (WBC) in the early detection of both aortofemoral and peripheral graft infections.One hundred sixty-two WBCs were performed on 129 consecutive patients with suspected aortofemoral (122 scans) and peripheral (40 scans) graft infection and in a 12-patient control group. Patients with suspected PVGI were categorized into three groups on the basis of their signs and symptoms on readmission: (a) patients with specific signs of graft infection (Group A); (b) patients with nonspecific signs of graft infection (Group B); and (c) patients with anastomotic aneurysms (Group C). Gram's stains of the perigraft exudate and graft cultures were performed and used as the gold standard in patients who underwent surgery. An 18-mo clinical follow-up was done to assess the presence or absence of graft infection in patients who did not have surgery.In patients with suspected aortofemoral graft infections, the overall sensitivity, specificity and accuracy of WBCs (Groups A, B, C) were 100%, 92.5% and 97.5%, respectively, whereas sensitivity, specificity and accuracy calculated in the patients with nonspecific signs of graft infection (Groups B, C) were 100%, 92.3% and 96.9%, respectively. In patients with suspected peripheral graft infections, sensitivity, specificity and accuracy were 100%.The white blood cell scan seems a reliable diagnostic method for early diagnosis of PVGI, and it is more useful in aortofemoral graft infections.
