Malignant hypertension secondary to iliac artery stenosis after kidney transplantation: a case report.

Iliac artery stenosis is a rare complication after renal transplantation. This complication affects elderly patients and related to atheromatous disease. It mimics the same clinical presentation as a transplant renal artery stenosis or renal artery stenosis. This entity is can be responsible for serious complications such as renal dysfunction, malignant hypertension and acute pulmonary oedema. We present in this paper the case of a 51-year-old patient, who benefited 7 years early of renal transplantation, with a good initial result, and who was admitted actually for malignant hypertension and renal function impairment due to an iliac artery stenosis proximal to the renal transplant and who was treated with a stenting angioplasty of the external iliac artery with a mixed outcome. Our case highlights the importance of the early diagnosis and treatment of such complications to avoid definitive renal failure and permanent hypertension.

Case Report: Mycotic common carotid artery pseudoaneurysm in a child. A case report.

Extracranial carotid artery aneurysms in children are extremely rare, nevertheless associated with a great potential of thromboembolic episodes and rupture especially those with mycotic origin. The surgical treatment is very challenging, and there is still a controversy concerning revascularisation after the resection of the aneurysm. In this manuscript, we report the observation of an 8-year-old boy with the medical history of Leukemia who is admitted urgently for a mycotic right common carotid artery aneurysm, occurring after a chemoport infection who was operated on in our cardiovascular surgery department with surgical resection and ligation. It is the second report in the pediatric literature of a mycotic pseudoaneurysm situated in the common carotid artery, but the first documented by medical imagery. Through this case, we highlight that ligation of the infected carotid artery can be a safe and efficient alternative especially in Children.

[Hybrid repair of aortic arch aneurysm]. / Traitement hybride des anévrismes de l'arche aortique.

BACKGROUND: The management of aortic arch aneurysms is challenging. If conventional surgery cannot be performed in high risk patients, endovascular treatment is confronted to the problem of endoleaks at long term. However, the hybrid repair combining a first surgical step and a second endovascular step is a new technique recently introduced in the therapeutic alternatives of aortic arch aneurysm but its long-term results are not well known. METHODS: We report a series of four patients who received hybrid treatment for aortic arch aneurysms in our department between 2016 and 2018. RESULTS: These were 3 men and 1 woman with an average age of 63 years [55-80 years]. All were hypertensive and only one patient had diabetes. The aneurysm was symptomatic of chest pain in all cases and it was ruptured in only one case. Preoperatively, the hemodynamic state was stable in the four patients with a mean aneurysm diameter of 60 mm [48-79 mm] on CT angiography and the landing zone was zone 0 in all cases. Under general anesthesia, the 1st step was surgical with the performance of an aorto-bicarotid bypass associated with a re-implantation of the left subclavian artery and a disconnection of the supraortic trunks. The 2nd stage was endovascular by the femoral route; with release of an aortic stent graft covering the ostia of all supraortic trunks. The final angiographic check-up showed complete exclusion of the aneurysm in all cases. The immediate postoperative follow-up was straightforward except for the onset of septic shock and death in a patient with an aneurysm ruptured in the left pulmonary branch initially. The mean follow-up was 12 months with a CT scan control which confirms the complete exclusion of the aneurysm and the absence of endoleak.
