How should I treat concomitant post-endarterectomy carotid pseudoaneurysm and contralateral symptomatic stenosis?
Background A 74-year-old male patient complaining of crescendo TIAs, hypertension and hyperlipidaemia. Investigation Duplex ultrasound scan MR angiography. Diagnosis Pseudoaneurysm stemming from the ICA. Treatment An open or endovascular procedure for the right pECCA repair, or a left CEA or CAS.
Anastomotic Pseudoaneurysm Complicating Renal Transplantation: Treatment Options
Introduction: Anastomotic pseudoaneurysm following renal transplantation is uncommon. Indications for repair, treatment options and outcomes remain controversial. Report: We present 6 renal transplant recipients with large anastomotic pseudoaneurysms. Five of the patients underwent open repair while one had a stent-grafting and delayed transplant nephrectomy for a ruptured pseudoaneurysm. A transplant nephrectomy was needed in all cases but one. Arterial reconstruction enabled limb salvage in all cases. One patient died of sepsis postoperatively. No patient presented late infection, failure of vascular reconstruction, nor pseudoaneurysm recurrence. Conclusions: Surgical excision of anastomo…

Altered expression of inflammation-related genes in human carotid atherosclerotic plaques.
Abstract Objective Inflammation is a pivotal process in atherosclerosis development and progression, but the underlying molecular mechanisms remain largely obscure. We have conducted an extensive expression study of atherosclerotic plaques to identify the inflammatory pathways involved in atherosclerosis. Methods We studied 11 human carotid plaques, their respective adjacent regions and 7 control arteries from different subjects. Expression of 92 genes was studied by TaqMan low-density array human inflammation panel. Human aortic endothelial and smooth muscle cells were used for in vitro experiments. Results The mRNA levels of 44/92 genes (48%) differed significantly between the tissues exa…

Endovascular versus open surgical repair of abdominal aortic aneurysm with concomitant malignancy
Background The management of patients with abdominal aortic aneurysm (AAA) and concurrent malignancy is controversial. This study retrospectively assessed the outcome of endovascular repair (EVAR) and open repair (OR) for the treatment of AAA in patients undergoing curative treatment for concomitant malignancies. Methods All patients who underwent surgery for a nonruptured infrarenal AAA of ≥5.5 cm and concomitant malignancy between 1997 and 2005 were retrospectively reviewed. Results Identified were 25 patients (22 men; mean age, 70.3 years) with nonruptured infrarenal AAA of ≥5.5 cm (mean size, 6.4 cm) and concomitant malignancy amenable for curative treatment. EVAR was used to treat 11 p…
Decreased Paraoxonase-2 Expression in Human Carotids During the Progression of Atherosclerosis
Objective— Many gene products involved in oxidation and inflammation are implicated in the pathogenesis of atherosclerosis. We investigated paraoxonase 2 (PON2), 5-lipoxygenase (5-LO), and 5-LO activating protein (FLAP) expression and malondialdehyde (MDA) levels in carotid lesions to assess their involvement in plaque formation. Methods and Results— We measured gene expression and MDA levels in atherosclerotic plaques from 59 patients undergoing carotid endarterectomy, and in plaque-adjacent tissue from 41/59 patients. Twenty-three fetal carotids and 6 mammary arteries were also investigated. Real-time polymerase chain reaction and immunohistochemistry revealed decreased PON2 expression i…
