This is the first reported case of successful management of a mycotic aneurysm of the inferior mesenteric artery. The only helpful clinical manifestations were episodes of previous abdominal pain and a history of bacterial endocarditis. The surgical management involved simple excision without revascularization of the inferior mesenteric artery.

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.

We report a case of a patient with mycotic pseudoaneurysm of the gastroduodenal artery who presented with hemoperitoneum and subcapsular hematoma of the liver. The diagnosis was established with contrasted abdominal CT scanning. Visceral angiography was not needed. Prompt recognition and surgical intervention led to a favorable outcome. Pseudoaneurysm of visceral vessels is an uncommon disease process, and to our knowledge, this is the first reported case that has presented with free blood in the peritoneal cavity and beneath the liver capsule. This case may also represent a rare complication of therapeutic ERCP procedures. Mycotic aneurysm or pseudoaneurysm of visceral vessels may develop from bacteremia and its dissection or rupture should be suspected in patients presenting with sepsis and abdominal pain.

Although mycotic aneurysms of small visceral arteries are rare, they have a high morbidity and mortality due to rupture and sepsis. Any patient with abdominal pain and bacterial endocarditis should be suspected of having a mycotic aneurysm. Selective arteriography confirms the diagnosis. In the case we have reported, diagnosis of a mycotic aneurysm of the inferior pancreaticoduodenal artery was established by angiography, and the patient was treated by percutaneous transcatheter embolization. This case demonstrates that mycotic aneurysms of small visceral arteries may be managed nonoperatively with antibiotics and percutaneous transcatheter embolization therapy.

A 44-year-old man died suddenly, shortly after admission to the hospital with complaints of abdominal pain. Medical history was significant for chronic alcoholism and homozygous hemoglobin C disease. Autopsy revealed vegetations on the aortic valve, especially on the left coronary cusp. There was anomalous origin of the coronary arteries from the left sinus of Valsalva. The large vegetation on the left coronary cusp had extended into the left main-stem coronary artery and obstructed it. There was evidence of prior embolization to the right coronary artery with mycotic aneurysm formation and myocardial infarction. Other lesions included a cerebral artery mycotic aneurysm and metastatic abscesses within the myocardium and spleen. Although the aortic valve was free of underlying chronic pathology, the causative organism was Streptococcus viridans. This case illustrates several unusual, and, in some instances, unique findings in infective endocarditis.

The superior mesenteric artery is a frequent site of mycotic aneurysm formation. With the increasing popularity of parenteral drug abuse the incidence of superior mesenteric aneurysms is likely to increase. It should be suspected in any patient who has a history of bacterial endocarditis, sepsis, and abdominal pain. Abdominal CT scanning and visceral angiography are most useful in establishing the diagnosis, and surgical therapy should ensue with minimal delay. The various intraoperative methods of eradicating this lesion are described, with a review of the literature and report of successful management of one such case.

The authors report a case of rupture of a mycotic aneurysm of the duodenal pancreatic arcade in a 68 year old man presenting with shock, abdominal pain and rigidity, complicating a case of infectious endocarditis. Emergency treatment consisted of selective embolisation with a coil. This treatment, proposed in view of the clinical condition of the patient and the anatomical particularity of the regional arterial vascularisation, may be a valuable alternative to classical surgery in this type of pathology.

Arteriovenous fistula between common iliac vessels is uncommon. Most of the reported cases are secondary to lumbar disc surgery. Mycotic aneurysm of iliac vessels caused by bacterial infection is even rarer. We describe the case of a 63 year old man with dyspnea, abdominal pain, bipedal edema, chills and fever. He had a right common iliac AVF as a result of a ruptured salmonella mycotic aneurysm, and the diagnosis was made by vascular duplex color scan.

Mycotic aneurysms have been associated with many clinical conditions. A tender pulsatile abdominal mass in association with fever, chills, and unrelenting back pain is suggestive of a leaking mycotic aneurysm. However, the extracranial manifestations of Tolosa-Hunt syndrome (THS) may mimic several of these symptoms. We report the case of a woman who was successfully treated with high-dose steroids for THS. Two months later, she was admitted to another hospital with rigors and unremitting back and abdominal pain. CT-guided aspiration of an L5-S1 paravertebral mass was done. The aspirate and blood cultures grew Staphylococcus aureus. Intravenous antibiotics and analgesics were administered with good relief. A month after discharge from that hospital, she was admitted to our hospital with classic signs and symptoms of a leaking mycotic aneurysm. She was treated surgically and has remained asymptomatic for 21 months. Tolosa-Hunt syndrome associated with mycotic aortic aneurysms has not been previously reported.

Aneurysms of the superior mesenteric artery (SMA) are an uncommon but lethal entity, which must be treated expeditiously to avoid mortality and high incidence of ischemic small bowel complications. In the past 7 years the authors have treated 4 patients with a variety of types of aneurysms involving the SMA and its branches at a university-based teaching hospital. The first was a mycotic SMA aneurysm as a result of septic mitral valve, the second a jejunal aneurysm in a patient with pancreatitis, the third a spontaneous dissection distal to a small SMA aneurysm with thrombus partially occluding the distal vessel, and the fourth an SMA aneurysm associated with the diagnosis of mesenteric insufficiency. All patients presented with abdominal pain. The diagnosis was made initially in 1 patient on plain abdominal films with a calcified aneurysm, on duplex scan in the second, and on computed tomography (CT) scans in the remaining 2. Treatment consisted of bowel resection and ligation of mycotic aneurysm in the first patient, of catheter embolization of jejunal aneurysm in the patient with pancreatitis, and of vein graft bypass in the patient with a large SMA aneurysm. The patient with SMA aneurysm and distal dissection with partially occluding thrombus received anticoagulation and is being followed up with serial CT scans. There were no deaths. One patient required bowel resection, which did not result in short gut syndrome. Improved abdominal duplex scanning and CT technology facilitates the diagnosis of mesenteric aneurysm. The broad spectrum of etiologies mandates that treatment be tailored to the individual patient, and it varies from endovascular techniques to traditional bypass surgery. Prompt diagnosis and treatment results in the lowest mortality rate and minimizes the prevalence of intestinal infarction.
