Abstract

348 cases of abdominal aortic aneurysm were reviewed for typical features of inflammatory aneurysm (IAAA) (marked thickening of aneurysm wall, retroperitoneal fibrosis and rigid adherence of adjacent structures). IAAA was present in 15 cases (14 male, 1 female). When compared with patients who had ordinary aneurysms, significantly more patients complained of back or abdominal pain (p less than 0.01). Erythrocyte sedimentation rate was highly elevated. Diagnosis was established in 7 of 10 computed tomographies. 2 patients underwent emergency repair for ruptured aneurysm. Unilateral ureteral obstruction was present in 4 cases and bilateral in 1. Repair of IAAA was performed by a modified technique. Histological examination revealed thickening of the aortic wall, mainly of the adventitial layer, infiltrated by plasma cells and lymphocytes. One 71-year-old patient operated on for rupture of IAAA died early, and another 78-year-old patient after 5 1/2 months. Control computed tomographies revealed spontaneous regression of inflammatory infiltration after repair. Equally, hydronephrosis due to ureteral obstruction could be shown to disappear or at least to decrease. IAAA can be diagnosed by computed tomography with high sensitivity. Repair involves low risk, but modification of technique is necessary. The etiology of IAAA remains unclear.

HydroCoil embolization of a ruptured infectious aneurysm in a pediatric patient: case report and review of the literature.

INTRODUCTION: Intracranial infectious aneurysms in the pediatric population are rare. Although surgery has been the traditional treatment of ruptured pediatric infectious aneurysms, endovascular coil embolization has become an attractive alternative due to its low rate of morbidity and mortality. CASE REPORT: A 9-year-old boy with a significant medical history of aortic valve replacement, antibiotic-treated infective endocarditis, and multiple embolic cerebral infarcts presented with a high-grade intraventricular hemorrhage due to the rupture of a large infectious proximal posterior circulation aneurysm. Computed tomography and cerebral angiogram demonstrated a right crural/ambient cistern hematoma and an associated infectious aneurysm of the right proximal posterior cerebral artery. The ruptured infectious aneurysm was coil-embolized with hydrogel-coated platinum coils without sacrifice of the distal parent artery. The aneurysm was completely occluded, and the patient regained all neurological function. CONCLUSION: Ruptured infectious aneurysms in the pediatric population occur despite aggressive medical therapy. Patients with infective endocarditis and embolic infarcts should be followed closely due to the risk of major hemorrhagic events, including aneurysm rupture. Hybrid coil embolization of ruptured infectious aneurysms with preservation of the distal parent artery is exceedingly rare and effective in the management of ruptured infectious aneurysms in the pediatric population.

Intrathecal aspergillosis and fusiform arterial aneurysms in an immunocompromised child: a clinico-pathological case report.

CASE REPORT: We describe a 12-year-old boy with subarachnoid hemorrhage. Cerebral angiography revealed multiple fusiform intracranial arterial aneurysms. Surgical therapy other than ventricular drainage was not feasible due to the extent and pattern of pathological changes. Aspergillus antigen was found in the cerebrospinal fluid (CSF). However, cultures of urine, CSF, and samples from the upper airways were negative for Aspergillus and other fungi. The boy was immunocompromised due to prophylactic antibiotic therapy for recurrent pneumonia and continuous steroid therapy for his hemolytic anemia. There were Aspergillus antigens but no evidence of ongoing infection with the fungus was found. The patient suffered recurrent intraventricular hemorrhage and died on the 31st day after admission. PATHOLOGICAL EXAMINATION: Pathological examination showed multiple fusiform aneurysms, hypertrophy of the intima, and destruction of the internal elastic membrane of the cerebral arteries. No fungus infiltration was detected. We speculate that the patient had previously had an Aspergillus infection, causing segmental destruction of the internal elastic membrane. However, we cannot rule out noninfectious vasculitis as possible etiology. CONCLUSIONS: In the immunocompromised child, fusiform segmental intracranial arterial aneurysms may be secondary to the destruction of the internal elastic membrane by fungus infection. The condition may present with aneurysm rupture and subarachnoid hemorrhage. In this patient group, surgical therapy is rarely an option and the prognosis is poor.
