The authors describe a sixty-seven-year-old hypertensive, diabetic man with a mycotic abdominal aortic aneurysm infected with Clostridium septicum. The patient had colonic polyps but no malignant disease. They could find only one other report of a mycotic aneurysm infected with C. septicum. In that case, as in most other cases of C. septicum bacteremia, the patient had gastrointestinal cancer. Their case suggests that treatment for a clostridial infection should be considered in patients with known gastrointestinal disease, signs and symptoms of sepsis, and abdominal pain. Conversely, patients known to have a C. septicum infection should be evaluated for gastrointestinal lesions.

338 patients with aorto iliac aneurysms were operated in the Department of vascular surgery (Hosp. E.-Herriot-University A.-Carrel Lyon). Retrospective evaluation found 20 solitary iliac artery aneurysms (AAIS) in 18 patients (2 bilateral AAIS). 77% of aneurysms were on the common iliac artery, 17% on the internal iliac artery, and one case of mycotic aneurysm on the external iliac artery. 8 patients (44.4%) were asymptomatic, 5 (27.8%) had non specific complaints. Rupture or acute ischemia occurred in 5 cases (27.8%). The incidence of non atherosclerotic cause (dysplasia 33.3%, infection 16.7%) in this series shows a real difference with AAA (atherosclerotic dominant etiologic factor). The value of C.T. scanning and sonographic evaluation and their extensive use in vascular and non vascular diagnostic problems are an obvious explanation for increasing AAIS reports. The risk of rupture is probably higher than in AAA because of the incidence of arterial dysplasias (1/3 in this study) and mycotic origin. This occurrence suggests an aggressive surgical management. Aneurysmorrhaphy with graft interposition by intraperitoneal approach is the routine technique for most of surgeons. An alternative procedure (retroperitoneal approach) was performed on ten of our patients (55.5%). No perioperative mortality and low morbidity rate (one case of phlebitis) in our cases support this surgical management. The survival rate based on actuarial method is estimated 64% at five years (all grafts patent).

A case of salmonella infrarenal aortic aneurysm that ruptured and was treated with staged operative procedures and a highly effective antibiotic is reported and analyzed. An emergency situation with a ruptured abdominal aortic aneurysm required prompt surgical intervention with an aortobifemoral graft insertion. In the immediate postoperative period it was realized that a prosthetic graft was placed in the bed of a mycotic aneurysm. The patient had significant arteriosclerotic occlusive disease limiting the distal anastomotic site to the common femorals. Interoperatively the superficial femorals were noted to be occluded chronically. Consequently, revascularization via an extra-anatomical bypass after aortobifemoral graft removal was more complex. This was managed in a staged delayed fashion, while suppressing the infecting organism with Cefotaxime. The details of this complex situation are described within.

Aortic graft infection may result in high mortality ranging up to 88%. Therefore, early diagnosis is imperative in the treatment of this serious complication. Computerised tomography (CT) is considered as a sensitive tool in the diagnosis of aortic graft infection. Some findings used as the criteria for infection, such as periprosthetic gas and fluid are, however, normal postoperative findings. The aim of this prospective study was to compare CT-scan and Tc-99m-HMPAO labelled leucocytes in the early diagnosis of aortic graft infection. The present study includes 24 consecutive patients (all men, age 70 +/- 8 years, range 55-85 years), who were operated on for abdominal aortic aneurysm. Prosthetic and suture materials were the same in all operations. Each patient was examined with the aid of CT-scan and imaged with Tc-99m-HMPAO labelled leucocytes 2 weeks and 3, 6 and 12 months after the reconstructive aortic surgery. Two radiologists and two specialists in nuclear medicine examined the data independently without knowing the clinical picture of the results of any other examinations of the patients. Seven patients (7/24; 29%) showed significant accumulation of labelled leucocytes in the first imaging (2 weeks postoperatively) with Tc-99m-HMPAO labelled leucocytes. Three months after the surgery only four patients (4/24; 17%) were positive in this respect. One of these patients had clinically proven aortic graft infection and another positive was a patient with resected and reconstructed mycotic aneurysm. CT-examination in all scans was suggestive for aortic graft infection in two cases (2/24; 8%), but neither of these patients showed any signs of infection.(ABSTRACT TRUNCATED AT 250 WORDS)

Ruptured abdominal aortic aneurysm is the major surgical emergency in the retroperitoneal compartment. Rupture of an abdominal aortic aneurysm is always fatal without urgent operative repair. Computed tomography is the reference standard for the diagnosis of ruptured abdominal aortic aneurysm in hemodynamically stable patients. At CT, the diagnosis is based on the combination of abdominal aortic aneurysm and extraluminal retroperitoneal blood. Retroperitoneal hemorrhage usually demonstrates both isodense and hyperdense areas. In most cases hemorrhage is located in psoas compartments and perirenal space. In the case of ruptured abdominal aortic aneurysm other findings may be demonstrated such as focal interruption of the aortic wall and active extravasation of contrast media in the retroperitoneal compartments. Inflammatory abdominal aortic aneurysm, that may present as acute abdominal pain, should be recognized and differentiated from ruptured abdominal aortic aneurysm. Inflammatory abdominal aortic aneurysm is characterized by a fibrotic process around the abdominal aorta that may entrap adjacent structures such as ureters, duodenum and inferior vena cava. Aortic dissection, mycotic aneurysm, and inferior vena cava thrombosis are less common. Complications occurring after emergency aneurysm replacement are also considered.

Despite advances in surgical technique and peri-operative care, mortality from ruptured abdominal aortic aneurysm presenting to a hospital remains around 50%. This is in contrast to the mortality rate of < 5% for elective repair. In a two and a half year period,the principal surgeon operated on 10 patients with ruptured AAA, with a peri-operative and overall mortality of 30%. One of the ten patients had a ruptured mycotic aneurysm. We present our experience with these patients and also correlate this with recent publications.

Tuberculous aneurysm of the aorta is exceedingly rare. To date, the standard therapy for mycotic aneurysm of the abdominal aorta has been surgery involving in-situ graft placement or extra-anatomic bypass surgery followed by effective anti-tuberculous medication. Only recently has the use of a stent graft in the treatment of tuberculous aortic aneurysm been described in the literature. We report two cases in which a tuberculous aneurysm of the abdominal aorta was successfully repaired using endovascular stent grafts. One case involved is a 42-year-old woman with a large suprarenal abdominal aortic aneurysm and a right psoas abscess, and the other, a 41-year-old man in whom an abdominal aortic aneurysm ruptured during surgical drainage of a psoas abscess.

Simultaneous treatment of Salmonella typhimurium-induced symptomatic abdominal aortic aneurysm with associated spondylitis. Bacterially infected aneurysms associated with local spondylitis, while representing a potentially fatal clinical picture, are an operative challenge for vascular surgeons and orthopaedic surgeons alike. In this context, the concurrent occurrence of an infection with Salmonella typhimurium as a causative agent is a rare observation. The case report gives an outline of the simultaneous vascular and orthopaedic surgical procedure. The subrenal mycotic aneurysm was removed in a first step. The continuity of the aorta was restored centrally through an autogenic aortic graft with caudal anastomosis to a dacron vascular prosthetic tube. Initially, the latter was chosen of excessive length so as to facilitate the orthopaedic surgeon's approach. Upon completion of stabilising surgery of the vertebral column, the dacron tube was reduced in length as necessary and the surgical area was enclosed with an omentum majus plastic mesh. No complications were noted during the 18-month follow-up period.

During 1993 to 2000 85 patients were treated for a ruptured abdominal aortic aneurysm. The average age of the patients was 72.4 years (46-90). 71 patients showed an infrarenal rupture and the remaining 14 a suprenal rupture. 76 of 85 cases were covered ruptures. All patients were operated upon. A tube graft was required in 43 cases and 31 needed a bifurcated graft. In further two cases an extraanatomical bypass was necessary due to a mycotic aneurysm. The operation on 11 patients could not be completed and 21 patients died in hospital during the postoperative period. On the other hand, 53 patients survived the rupture of the aneurysm. The mortality rate was 37.6 %. The early non-surgical complications dominated during the postoperative period. Respiratory failure, renal failure and cardiac failure were responsible for the mortality rate. It is unforseeable which patients will survive the emergency operation. Therefore it is always appropriate to attempt the reconstruction of an acutely ruptured AAA.

This report describes a 56-year-old man with a ruptured infected abdominal aortic aneurysm secondary to Salmonella bacteremia, initially presenting as acute pyelonephritis. Spike fever with severe back pain continued despite empiric antibiotic treatment at a local hospital. Hypotension with a sudden hemoglobin drop was observed on the second hospitalization day. Abdominal computed tomography to further examine the bleeding focus confirmed a rupture of the mycotic abdominal aortic aneurysm. This case was successfully treated through prompt surgical intervention and aggressive protracted antibiotic therapy. The case presented herein raises concerns about the uncommon but life-threatening mycotic aneurysm presented initially as acute pyelonephritis. Early diagnosis and appropriate surgical and antibiotic treatment of the Salmonella mycotic aortic aneurysm is crucial for a satisfactory outcome.
