BACKGROUND: Diffuse dermal angiomatosis (DDA) is a rare, acquired, reactive vascular proliferation, clinically characterized by livedoid erythematous-violaceous plaques, which frequently evolve to ulceration and necrosis. Histopathologically, it is manifested by a diffuse proliferation of endothelial cells within the full thickness of the dermis. DDA has been mainly associated with severe peripheral atherosclerosis. METHODS: We report a 63-year-old woman who presented with multiple erythematous-violaceous plaques with central deep skin ulcers on thighs, lower abdomen, and perianal area, associated with intermittent claudication, low-grade fever, and weight loss...

An isolated stenotic or occluded segment of the descending thoracic and/or the abdominal aorta associated to Takayasu's arteritis (TA) is very uncommon and the clinical expression is known as "middle aortic syndrome." Manifestations depend on the lesion location, and may include hypertension originating from the aortic coarctation or renovascular, buttock, or lower extremity claudication and rarely chronic intestinal angina. We present 2 female patients with TA with occlusive lesions in the infrarenal aorta; both were treated with open surgical reconstruction of the affected segments...

What is the central question of this study? To what extent focal abdominal aortic aneurysmal (AAA) disease is associated with systemic remodelling of the vascular tree remains unknown. The present study examined whether anatomical differences exist between distances of the intervisceral artery origins and AAA location/size in patients with disease compared with healthy patients. What is the main finding and its importance? Intervisceral artery distances were shown to be consistently greater in AAA patients, highlighting the systemic nature of AAA disease that extends proximally to the abdominal aorta and its branches...

BACKGROUND: Renal injury is an important complication of infrarenal aortic occlusion (IAO), which is mainly encountered during the postoperative period. Aortic clamping procedure may lead to turbulent blood flow and eventually vasoconstriction at renal arterial level of the abdominal aorta. IL-18BP has well-known antioxidant and anti-inflammatory properties. In this study, we aimed to determine whether IL-18BP has anti-inflammatory, antiapoptotic, antioxidant, and protective effects on acute kidney damage induced by IAO rat model...

Acute thrombotic or embolic occlusion of the abdominal aorta is a rare vascular emergency associated with high morbidity and mortality rates. Classically, the clinical presentation is a severe peripheral ischemia with bilateral leg pain as the predominant feature. Aortic occlusion presenting as an isolated acute onset of paraplegia due to spinal cord ischemia is very rare and requires improved awareness to prevent adverse outcomes associated with delayed diagnosis. We report the case of a 54-year-old man who presented with sudden paraplegia due to the thrombotic occlusion of the infrarenal aorta involving the first segment of the common iliac arteries on both sides; emergent transperitoneal aorto iliac thrombectomy combined with the endovascular iliac kissing-stent technique were performed achieving perioperative complete regression of the symptoms...

Acute limb ischemia (ALI) is a limb-threatening and life-threatening disease process. Mural aortic thrombosis (MAT) is a rare cause of ALI. While there is limited evidence on the use of bedside ultrasound for the detection of ALI or MAT, duplex ultrasound remains the standard in the diagnosis and ultimate medical decision-making in patients with acute and chronic limb ischemia. Point-of-care ultrasound may be used in the evaluation of patients with signs and symptoms of this disease entity. This is a case of a 79-year-old female with a complicated medical history, who presented with a pulseless right leg and abdominal tenderness...

The authors share herein their experience in reconstructive interventions on the aortofemoral segment in infection of the implant in three 59-to-69-year-old male patients. Infection of the prosthesis was diagnosed by the clinical data, findings of MSCT angiography and duplex scanning of the infrarenal portion of the aorta and arteries of lower limbs. Pseudoaneurysms of distal anastomoses were revealed in two cases. All secondary reconstructions were performed with the use of a cryopreserved aortic bifurcation homograft in the in situ position with simultaneous removal of the infected implant...

Situs inversus is a rare congenital defect defined by a mirror image anatomic variation of the thoracic and abdominal organs. In this situation, abdominal aortic surgery may become particularly challenging. This is the case of a 51-year-old man, who presented with an incapacitating lower limb claudication. On his workup, a complete occlusion of the infrarenal aorta requiring surgical revascularization was found. Additionally, a situs inversus totalis was identified along with a single horseshoe kidney. The patient underwent uneventfully a surgical aortobifemoral interposition...

PURPOSE: Severe local and systemic tissue damage called ischemia/reperfusion (IR) injury occurs during the period of reperfusion. Free oxygen radicals and proinflammatory cytokines are responsible for reperfusion injury. IL-18 binding protein (IL-18BP) is a natural inhibitor of IL-18. The balance between IL-18 and IL-18BP has an important role in the inflammatory setting. The present study aimed to investigate whether IL-18BP had a protective role in remote organ hepatic IR injury. METHODS: Wistar-Albino rats were divided into three groups that contained seven rats...

OBJECTIVE: In our prior study, we showed that delta-opioid peptide [D-Ala(2), D-Leu(5)] enkephalin (DADLE), by regional perfusion into the abdominal aorta, could protect the spinal cord against ischemia-reperfusion (I/R) injury caused by aortic occlusion. However, the relative dose-response effects of DADLE still remain unclear. This study investigated whether DADLE has a dose-dependent efficiency on spinal cord I/R injury. METHODS: New Zealand White rabbits were randomly divided into one of six groups: normal saline (NS; n = 8), DADLE (D) groups D0...
