Repetitive contained rupture of an infected abdominal aortic aneurysm with concomitant vertebral erosion

Vertebral body erosion by a chronic contained rupture of thoraco-abdominal aortic aneurysm: systematic review and spine surgical recommendations

BACKGROUND

Vertebral body erosion (VBE) is commonly caused by neoplastic, inflammatory or infectious diseases: it can be rarely associated with aortic wall disorders, such as contained rupture of aortic aneurysm (CCR-AA). CCR-AA is a rare event consisting of less than 5% of all reported cases. This condition is easily undiagnosed, differential diagnosis may be challenging, and there is no consensus or recommendation that dictates guidance on management of spinal surgical treatment.

MATERIAL AND METHODS

We performed a systematic review of literature of all cases of VBE secondary to CCR-AA to identify clinical, radiological, and surgical outcome characteristics with the aim of providing a basis for future research studies.

RESULTS

The search returned a total of 80 patients. All reported cases have a history of hypertension. In almost all cases the AA size reported was very high (mean diameter of 7.056 cm). The treatment of this condition involves various reported treatment strategies: a totally conservative approach, treatment of the aortic aneurysm through a minimally invasive endovascular procedure, or through open surgery and combined approach. Despite the wide variability in therapeutic strategy, the rate of good outcomes was 80%, relatively high.

CONCLUSIONS

''Back pain'' and pain along the vertebral column are such frequent complaints that unusual etiologies or serious and life threatening complications may be overlooked. In addition to the common traumatic and degenerative causes of back pain, AA must also be considered. A combined approach between vascular and spine surgery could be achieved without any increased risk.

Extensive Erosion of Vertebral Bodies Due to a Chronic Contained Ruptured Abdominal Aortic Aneurysm

This report describes a case of chronically ruptured abdominal aortic aneurysm contained within the lumbar vertebral bodies that presented with dull abdominal pain. Sudden, massive hemorrhage is an uncommon, yet well-known complication of an untreated abdominal aortic aneurysm. In addition, misleading clinical and radiological findings present difficult diagnostic challenges in such cases. This report emphasizes the findings obtained with multidetector computed tomography and delineates the differentiation of this condition from similar pathologies.

Ruptured Pneumococcal Aortic Aneurysm Presenting as ST-Elevation Myocardial Infarction: Case Report and Literature Review

Ruptured mycotic aneurysms occur infrequently in current clinical practice, and a pneumococcal etiology is even more rare. This case report describes a patient who initially presented with catheter lab activation for an acute ST-elevation myocardial infarction, receiving a full Plavix load. She was subsequently found to have a ruptured aortic aneurysm and underwent emergency surgical repair, with intraoperative findings of an aorta seeded with Streptococcus pneumonia. A retrospective evaluation of her history revealed clues of a previous upper respiratory infection and long-standing back pain. The subsequent literature review summarizes presentations and outcomes in previously reported, ruptured pneumococcal aneurysms and describes the relatively common occurrence of aortic conditions masquerading as acute myocardial infarctions. We provide recommendations to help approach similar situations in the future.

A migrated aortic stent graft causing erosive spondylopathy

We report about a patient presenting with back pain 4 months after an uneventful endovascular implantation of an aortic stent graft. Computed tomography scan revealed a migration of the stent with consecutive endoleakage, kink formation, and movement of the stent toward the spine, which caused destruction of the aortic wall as well as vertebral necrosis. Explantation of the stent and replacement of the native aorta relieved the patient of his symptoms.

Infectious or noninfectious? Ruptured, thrombosed inflammatory aortic aneurysm with spondylolysis

Osteolysis of vertebrae due to inflammatory aortic aneurysm is rarely observed. However, it is estimated that up to 10 % of infectious aneurysms coexist with bone tissue destruction, most commonly the vertebrae. Inflammatory aneurysms with no identified infection factor, along with infiltration of adjacent muscle and in particular extensive destruction of bone tissue have rarely been described in the literature. A case of inflammatory aneurysm with posterior wall rupture and inflammatory infiltration of the iliopsoas muscle and spine, together with extensive vertebral body destruction, is presented. The aneurysm was successfully treated with endovascular aneurysm repair EVAR.
