A woman in her 80s with an infrarenal aortic aneurysm was scheduled for endovascular aortic repair (EVAR). The aneurysm had a severely angulated neck (SAN), and the Zenith Flex device was selected. Completion angiography showed migration of the main body resulting in right renal artery stenosis. A Palmaz genesis was placed across the renal orifice. The patient had no renal dysfunction and was discharged 7 days after EVAR. If Zenith Flex devices are used for a SAN, it is necessary to consider not only the position of the renal artery but also the appropriate position of the stent-graft...

We herein report a successful repair of an internal iliac artery aneurysm in a renal transplant patient. At renal transplantation, the main renal artery and accessory renal artery had been anastomosed to the right internal iliac artery and right external iliac artery, respectively. The patient underwent resection and graft replacement of the iliac artery aneurysm with reattachment of the main renal artery to the right external iliac artery through a midline laparotomy with repeated topical cold perfusion for renal protection...

We report the rare case of a 54-year-old man with uncontrolled renovascular hypertension, who was found to have an abdominal aortic aneurysm with congenital solitary pelvic kidney and superior mesenteric artery stenosis. A single renal artery branched from aneurysmal aortic bifurcation, and both the renal artery and the superior mesenteric artery (SMA) had severe stenosis at their origins. The aneurysm was repaired with a bifurcated Dacron graft, to which the renal artery was anastomosed. SMA bypass was created between the graft's left limb and the SMA using another Dacron graft...

OBJECTIVE: Renal artery (RA) aneurysm (RAA) is a rare and complex disease. Treatment options for a RAA include endovascular surgery and open surgery with ex vivo repair or in situ reconstruction. This study evaluated the long-term outcome after vascular reconstruction of RAAs using the tailoring technique. Tailoring or aneurysmorrhaphy means a partial resection of the aneurysm with direct suture of the remaining arterial wall. METHODS: A single-center retrospective study was conducted between January 1990 and December 2015...

Renal involvement of systemic vasculitides is an emergency in nephrology. Although it has become very rare, the diagnosis of polyarteritis nodosa must be considered in some patients. A 70-year-old patient, previously healthy, presented with acute renal failure and malignant hypertension and abundant albuminuria. Subcutaneous nodule, orchitis and mononeuritis appeared subsequently. The search for auto-immunity or viral infection was negative. Markers of thrombotic microangiopathy, present initially, resolved after blood pressure control...

We report a case in which a stent graft and an Amplatzer® vascular plug (AVP) were effective for the treatment of chronic aneurysmal aortic dissection. The patient was a 52-year-old man. At 45 years of age, he developed acute aortic dissection, for which he underwent surgery four times with prosthetic graft replacement in the abdominal aorta, descending thoracic, ascending aorta (without neck branch reconstruction), and thoracoabdominal aorta with the reconstruction of the celiac, superior mesenteric and bilateral renal arteries...

The aim of this study is to present the treatment of a juxtarenal inflammatory aneurysm using a Nellix device (Endologix, Inc., Irvine, CA) to seal the entire aneurysmatic aorta combined with bilateral iliac-renal bypass using the Gore hybrid vascular graft (W. L. Gore & Associates, Inc., Flagstaff, AZ). A 63-year-old man was diagnosed with a 6-cm juxtarenal inflammatory aneurysm. It was initially decided to treat him with an aorto-aortic bypass and to revascularize the 2 renal arteries with "graft to renal artery bypass" using Gore hybrid vascular grafts...

OBJECTIVES: This study sought to evaluate the diagnostic yield of a dedicated computed tomography angiography (CTA) protocol of the chest, abdomen, and pelvis in patients with fibromuscular dysplasia (FMD). BACKGROUND: FMD is an uncommon vascular disease that may result in stenosis, dissection, or aneurysm of nearly all arterial distributions, typically affecting medium-sized arteries. Findings from the United States Registry for Fibromuscular Dysplasia have suggested the potential need to perform screening imaging of the aorta and medium branch vessels...

Pregnancy-related rupture of an arterial aneurysm is an unusual occurrence associated with increased risk of morbidity and mortality. Various pregnancy-related physiologic changes appear to make pregnancy a high-risk situation for rupture of either preexisting arterial aneurysms or those that develop throughout the course of pregnancy. Splenic artery aneurysms are the most common (60%), followed by hepatic (20%), superior mesenteric (5.9%), celiac (4%), ovarian, uterine, and renal (<2%) artery. Even rarer are aneurysms involving the internal iliac artery and its branches, to which there is only one published case report...

Compartment syndrome (CS) is a pathological increase of the interstitial pressure within the closed osseous fascial compartments. Trauma is the most common cause, followed by embolization, burns, and iatrogenic injuries; it usually involves the limbs. The major issue when dealing with CS is the possibility to do an early diagnosis in order to intervene precociously, through a fasciotomy, reducing the risk of tissue, vascular and nervous damage. Although it is an infrequent condition, it is potentially life threatening...

Renal angiomyolipoma (AML) is a benign renal tumor with a risk of rupture in intratumoral aneurysms. Although renal AML in pregnancy is rare, risk of rupture is greater. Management for AML and childbirth is important during pregnancy; however, it is undefined yet. We present a case of hemorrhagic angiomyolipoma in pregnancy that is effectively managed by immediate cesarean section and elective transcatheter arterial embolization.
