To reduce the risk of persistent sequelae after fasciotomy, careful preoperative planning and meticulous perioperative care is needed to avoid multiple operations and post-fasciotomy complications. Patients whose wounds healed by secondary intention showed the best outcome.
The good discrimination of these scoring systems indicates their value as an adjunct to clinical assessment but should not be used on an individual basis as a clinical decision-making tool.
The RCRI's discriminatory capacity is low, and this raises difficulties in assessing cardiac risk in patients undergoing vascular intervention. The AMI is highest in the OMT group without prior cardiac intervention, which mandates protocols to identify patients requiring cardiac intervention prior to vascular procedures.
Case descriptionWe report a case of a 67-year-old male admitted to our services with a spontaneous contained rupture of the suprarenal abdominal aorta. Four months prior to his presentation to the vascular services, this gentleman was diagnosed with HIV and was subsequently reviewed by the infectious disease physicians. His CD4 count at that time was 128 (7.4%) and it was noted that he had had a reactivation of Herpes zoster suggestive of immunosuppression. It was thus decided to start him on highly active antiretroviral therapy (HAART) commencing with Combivir (lamivudine and zidovudine) and efavirenz. On routine screening, he was negative for both Hepatitis B and C; however, his venereal disease research laboratory serology test was positive, a diagnosis of latent syphilis was made and a course of benzylpenicillin was commenced.Four months post-HIV diagnosis, he presented as an emergency admission with right upper and lower limb weakness, slurred speech and right facial droop. In the first week of that admission, he developed sudden severe lower back pain and worsening of his lower limb weakness. An MRI scan was performed demonstrating an infiltrating mass at the level of the juxtarenal aorta and thought initially to be consistent with an infiltrating Kaposi's sarcoma. A CT angiogram was obtained and this confirmed the mass to be a suprarenal aortic haematoma with the aortic rupture site located immediately below the origin of the superior mesenteric artery and involving the aorta at the level of the right renal artery (Figure 1).He underwent an endovascular repair using a right renal chimney graft to extend the landing zone for an aortic exclusion graft. The aortic main body graft comprised a Talent TM (Medtronic, Santa Rosa, CA, USA) aortic extension graft (AXF3030W28AX: 30 mm  28 mm). The right renal artery 'chimney graft' was a Viabahn TM (Gore Medical, Flagstaff, AZ, USA) endoprosthesis (PAH080502: 8 mm  50 mm  120 mm) deployed via the left brachial
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
