Iliac Artery Reconstruction with Femoral Vein After Bare Metal Stent Infection

Introduction Primary infection of a bare metal stent is a rare condition, associated with significant morbidity and mortality. Definitive treatment includes stent removal and arterial reconstruction. Report This study details a common iliac stent infection after re-intervention for iliac stent occlusion, complicated by pseudoaneurysm formation and septic embolisation. Potential risk factors for stent infection were identified. An open surgical resection of the affected artery along with all stent material was performed, followed by reconstruction with autologous interposition superficial femoral vein. There were no complications and no recurrent infection at 6 months follow-up. Conclusion Although rare, bare metal stent infection may occur, and a high index of suspicion is required. Stent surgical removal and arterial in situ reconstruction with autologous femoral vein proved to be a definitive procedure with no mid-term morbidity.

Ovarian hyperstimulation syndrome as a rare cause of acute bilateral limb and renal ischemia

Ovarian hyperstimulation syndrome (OHS) is a rare and potentially fatal condition, particularly when it is associated with arterial thromboembolic events. We present a case of acute ischemia of both lower limbs and left kidney due to OHS. The clinical presentation included voluminous ascites, pleural effusion, and significant ovarian enlargement. Subsequently, bilateral severe acute limb ischemia and left kidney segmental infarction were established. Surgical thromboembolectomy and muscle débridement of the lower limbs were necessary, and the patient recovered with partial limitations. A high index of suspicion and timely treatment are essential to minimize consequences of arterial thrombosis associated with OHS.

Bridging thoracic endovascular aneurysm repair for a late rupture following aortic coarctation angioplasty.

UNLABELLED Introduction Thoracic endovascular aneurysm repair has been employed to treat late complications after aortic coarctation correction. However, its use in children has seldomly been reported. Case report We present the case of a 15-year-old child who presented with a ruptured aneurysm of the descending aorta complicated later by an aortic-oesophageal fistula following aortic coarctation stenting that was managed with multiple bridging endovascular interventions until a definitive repair was performed. CONCLUSION Thoracic endovascular aneurysm repair may be used successfully as a bridging intervention to a definitive repair in children with life-threatening aortic complications following aortic coarctation repair.

Estenose intra-stent na artéria femoral superficial: soluções actuais para um problema crescente

Resumo Os ultimos anos de tratamento da doenca arterial obstrutiva periferica na arteria femoral superficial observaram uma mudanca de paradigma, da cirurgia classica para a endovascular, o que se traduziu na utilizacao progressiva de stents metalicos para a manutencao da permeabilidade a longo prazo. Apesar dos avancos tecnologicos, a restenose intra-stent e uma das principais limitacoes do tratamento endovascular, com um tratamento complexo e nao consensual, traduzindo a escassez de resultados obtidos ou a sua manutencao no tempo. Os autores procuraram recolher os dados mais recentes sobre este tipo de patologia e as principais opcoes disponiveis para o seu tratamento.
