Chronic rupture of an abdominal aortic aneurysm (AAA) is a rare occurrence, the presentation of which is unusual, often mimicking other conditions such as femoral neuropathy or radicular compression syndrome. We report herein the case of an 87-year-old woman found to have a contained rupture of an AAA after presenting with back pain and obstructive jaundice. A computed tomography (CT) scan revealed the contained rupture of the aneurysm with a large hematoma compressing the common bile duct. Surgical repair of the aortic aneurysm was successfully performed and the patient remains well.

A 37-year-old patient with back pain and somatomegaly was found to have a penetrating aneurysm of sections IV and V of the abdominal aorta. Results of a family history and clinical examination confirmed suspicions of Marfan's syndrome. Further angiologic studies depicted an aneurysmatic dilatation of the left popliteal artery. Aneurysmatic dilatations are primarily located in sections I and II of the thoracic aorta, whereas aneurysms in sections IV and V are much rarer. The rare combination of an abdominal aortic aneurysm and left-sided popliteal aneurysm accompanying Marfan's syndrome is presented.

The effect of active absorbable algal calcium (AAA Ca) with collagen and other matrix components on aging-associated skin changes and backache and joint pain was tested in a case-controlled study of 40 test subjects and 40 age-matched control subjects (mean age, 65 years) complaining of backache and knee joint pain due to osteoarthritis, spondylosis deformans, and/or osteoporosis. Supplementation with 900 mg calcium (given as AAA Ca) and 3.5 g collagen and other matrix components, including glucosamine, daily for 4 months resulted in a marked alleviation of subjective pain, assessed by the face scale. A fall of skin impedance in response to exercise loads, such as standing up, walking, squatting, and climbing up and down stairs, reported as an objective manifestion of pain, was also alleviated. The basal skin impedance, which increases with age, was significantly reduced in response to the Ca-collagen-matrix supplementation, suggesting a change of skin properties similar to rejuvenation, along with subjective smoothening and moistening of the skin. Urinary excretion of N-terminal crosslinking telopeptide of type I collagen (NTx) was decreased in the Ca-collagen-matrix supplementation group, but not in the control group. In addition to calcium suppression of parathyroid hormone, preventing bone resorption, collagen, acting on the intestinal lymphatic system, may protect collagen from degradation through the inhibition of cytokine-induced release of metalloproteinases, including collagenase.

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.

A 93-year-old patient with a cardiac pacemaker and biochemical renal failure presented with back pain suspicious for dissection. We performed gadolinium-enhanced thoracoabdominal multidetector CT angiography using eight-channel multidetector CT. Uniform aortic enhancement of 140 HU was sufficient to exclude aortic dissection and defined an unruptured infrarenal abdominal aortic aneurysm.

The authors present the issue of rare causes of retrospinal back pain. Particular attention has been given to abdominal aortic aneurysm--it's clinical picture, diagnostic problems and treatment modes. A retrospective evaluation of 65 operated patients was performed. Diagnostic problems in a 66-year-old patient are also presented: the final diagnosis was determined at the time of surgery, although a low back pain treatment regimen had been formerly applied to this patient. The authors emphasise the frequent occurrence of atypical clinical signs accompanying abdominal aortic aneurysm, frequent correlation with degenerative changes of the spine, and the importance of differential diagnostics in patients with atypical symptoms of low back pain.

Unusual as well as well-known complications can occur after aortic reconstruction. In an effort to heighten awareness of these possibilities, a case is presented of a 71-year-old male who was brought to the emergency department with severe back pain of 2 days duration and hypotension. He had undergone repair of an infrarenal abdominal aortic aneurysm 6 years earlier. An emergency computed tomography scan demonstrated a 10-cm abdominal aortic aneurysm extending from just above the celiac axis, through the aortic bifurcation, with retroperitoneal and intraperitoneal hematoma. He was found at operation to have extension of his aneurysmal disease proximally, with complete separation of the proximal suture line, and rupture of the distal aortic wall. Since the aneurysm had been closed around the graft at the time of the original operation, his aneurysm had essentially been restored, and the diseased wall was again exposed to the tensile stresses from the pulsatile column of blood. Emergency repair was successful, despite postoperative complications including myocardial infarction, and later rupture of an iliac artery aneurysm. Patients presenting with signs and symptoms consistent with a ruptured abdominal aortic aneurysm after previous repair should be addressed aggressively with computed tomography if it is immediately available and the diagnosis is in doubt. The patient should then undergo an immediate operation. Such recurrence, although rare, must always be considered a possibility. Similar scenarios may be encountered secondary to endoleaks occurring after endoluminal aortic repairs.

We present the case of a 16-year old student with Marfan's syndrome and abdominal aortic aneurysm who presented with a diagnostic conundrum. He presented with a three months history of progressive painful left upper abdominal mass and back pain. It became severe in the last two weeks before presentation and was associated with constipation. This mass was thought to be of splenic origin but the initial ultrasound suggested a pancreatic pseudocyst. Review of his previous hospital record revealed that he had been treated for severe myopia which started at infancy. Another opthalmic review at our centre revealed bilateral ectopia lentis. He had no cardiac signs and no family history of cardiovascular diseases. He is the 6th of 8 siblings, all the family members are alive and healthy except one sibling who died at 7 months. The diagnosis of abdominal aortic aneurysm was only made at laparotomy and confirmed by on-table aortogram. He had excision of the aneurysmal sac and replacement with on-lay dacron tube graft. He died on the 4th post-operative day. A diagnosis of abdominal aortic aneurysm was not made at initial presentation because of the rarity of this condition in our environment and incompetence of the ultrasonographer. Aortic aneurysm in Marfan's syndrome is commonly found in the thoracic part of the aorta, however in this case, it is abdominal. A high index of suspicion is necessary to avoid missing this pathology, therefore the need for vigilance.

Four cases among the 149 patients who required repair of an infrarenal abdominal aortic aneurysm (AAA) during the last five years, were chronic contained rupture. The first symptom at onset was back pain and physical examination revealed the patients to be in no acute distress. The sites of rupture were posterior in all cases. They were operated through an extraperitoneal approach. There was no operative mortality and all survived. The CT features, (1) discontinuity of the rim of calcification in the true aneurysm wall, (2) well defined soft tissue density adjacent to the aorta, (3) the concealed psoas muscle and the displaced viscera depending on the size of the lesion, and (4) no appearance of contrast material in the hematoma in some cases, led to the correct diagnosis of contained rupture.

Endotension leading to enlargement of the aneurysm sac following the endoluminal grafting is still handled as an exclusive phenomenon of the endovascular aneurysm repair (EVAR). We report on a case with aneurysm sac enlargement caused by endotension leading to aneurysm rupture after conventional, open aneurysm repair, a so far not described complication. In a 74-year-old patient, following open surgical standard resection and reconstruction of an abdominal aortic aneurysm, a routinely performed abdominal ultra-sonography demonstrated a slowly growing enlargement of the peri-prosthetic aneurysm sac without endoleak. During the pre-operative work-up of the cardiac and pulmonary risk profiles, he complained of abdominal pain and back pain. Control CT revealed contrast inside the aneurysm sac as well as in the right-sided retroperitoneum. At the emergency operation a retroperitoneal haematoma was noticed. Opening the ballooned aneurysm sac, a fresh haematoma was also found. Lifting up the prosthesis, back bleeding at the dorsal circumference of the proximal anastomosis was confirmed due to a 2 cm long disruption of the anastomosis. In patients who present with abdominal or back pain after conventional surgery of an abdominal aortic aneurysm, a contrast CT should be performed to exclude an endoleak as well as other pathologies. The enlargement of the aneurysm sac without endoleak could be interpreted as endotension, with the consequence of urgent re-operation to prevent rupture.
