Rupture of a True Giant Aneurysm of the Posterior Tibial Artery: A Huge Size of 6 cm on Diameter

True aneurysms of tibial artery are rare occurrences and their rupture is really rare. We report the case of a 59-year-old man who, after an episode of bacterial endocarditis, presented a posterior tibial aneurysm formation evolved in rupture. To our knowledge, this is the first case of a true giant aneurysm rupture of the posterior tibial artery (diameter, 6 cm). The treatment consisted of aneurysmectomy and surgical arterial ligation. A follow-up of 24 months was performed with good results.

Use of Contrast-Enhanced Ultrasound in Carotid Atherosclerotic Disease: Limits and Perspectives

Contrast-enhanced ultrasound (CEUS) has recently become one of the most versatile and powerful diagnostic tools in vascular surgery. One of the most interesting fields of application of this technique is the study of the carotid atherosclerotic plaque vascularization and its correlation with neurological symptoms (transient ischemic attack, minor stroke, and major stroke) and with the characteristics of the “vulnerable plaque” (surface ulceration, hypoechoic plaques, intraplaque hemorrhage, thinner fibrous cap, and carotid plaque neovascularization at histopathological analysis of the sample after surgical removal). The purpose of this review is to collect all the original studies available in literature (24 studies with 1356 patients enrolled) and to discuss the state of the art, limits, and future perspectives of CEUS analysis. The results of this work confirm the reliability of this imaging study for the detection of plaques with high risk of embolization; however, a shared, user-friendly protocol of imaging analysis is not available yet. The definition of this operative protocol becomes mandatory in order to compare results from different centers and to validate a cerebrovascular risk stratification of the carotid atherosclerotic lesions evaluated with CEUS.

Popliteal Artery Entrapment Syndrome in a Young Girl: Case Report of a Rare Finding

The popliteal artery (PA) entrapment syndrome, a rare cause of arterial thrombosis, is most often encountered in young male athletes. Here, we report a very unusual case of PA entrapment syndrome in a 14-year-old girl who presented with a 1-month history of calf claudication to our observation facility. Diagnostic work-up revealed obesity, sedentary lifestyle, and an aberrant accessory slip of the medial head of gastrocnemius around the PA. Arterial echo color Doppler ultrasonography and computed tomographic angiography studies were performed. Surgical treatment involved revascularization with resection of the medial head of gastrocnemius, the cause of the arterial entrapment, and enlargement angioplasty using an autologous saphenous vein patch, in combination with antiplatelet therapy, resulting in restitution ad integrum of the affected limb and, finally, an improved quality of life of the patient. This case underscores the importance of clinical suspicion, diagnosis, and treatment of lower-limb claudication in very young patients presenting with unusual symptoms. If missed, the condition may evolve dramatically. Prompt diagnosis and surgical treatment are key to complete recovery and the prevention of irreversible complications that may result in limb loss.

Preoperative and Postoperative Evaluation of New Double Mesh Carotid Stents with Contrast-Enhanced Ultrasound and Diffusion-Weighted Imaging

In this case series, we selected 4 patients with asymptomatic severe carotid stenosis due to unstable plaques, which were identified with contrast-enhanced ultrasound. These patients underwent carotid stenting with a new generation double mesh stent. Diffusion-weighted magnetic resonance imaging (DW-MRI) was executed before and after the procedure to detect early cerebral microembolizations. No early neurological complications occurred nor cerebral microembolizations were detected at DW-MRI. New double mesh carotid stents appear to be a safe option also in asymptomatic patients with unstable plaques at high risk for surgery.

Primary Aortoenteric Fistula of a Saccular Aneurysm: Case Study and Literature Review

Primary aortoenteric fistula is a direct communication between the aorta and intestinal lumen and it represents a rare but potentially lethal complication of an abdominal aortic aneurysm. However, it may occur less frequently in a naive non-aneurysmatic aorta. Diagnosis is often difficult and delayed in most cases, unless there is a high level of clinical awareness. Urgent surgery is still the recommended treatment. We describe the case of primary aortoenteric fistula of a saccular aneurysm. A 55-year-old woman was referred to our center with hematemesis, melena, and severe anemia who was dignosed previously with unknown saccular abdominal aneurysm.

Successful Management with 2 Overlapping Bare Stents for Post–Carotid Endarterectomy Carotid Pseudoaneurysm Secondary to Carotid Shunt

Pseudoaneurysms are a rare complication of carotid endarterectomy. We successfully excluded with 2 overlapping bare stents a distal carotid artery pseudoaneurysm very likely induced by a Pruitt-Inahara shunt 2 months after carotid endarterectomy.

Rupture of giant superficial femoral artery aneurysm in a leukemic patient submitted to chemotherapy.

The superficial femoral artery (SFA) is a relatively rare location for lower limb aneurysmatic disease. In the literature, this disease is described an association between a relatively high growth rate and/or the rupture of aneurysms and chemotherapeutic agents. We report a case of the rupture of a giant SFA aneurysm in a patient during chemotherapy for acute lymphatic leukemia.

A severe cause of pulsating varicose veins

In June, 2010, a 66-year-old woman presented to us with a 2 month history of a bilateral pulsatile swelling in her groin. On examination she was in chronic atrial fi brillation. She had been on oral anticoagulant therapy since a mitral valve replacement in 1998. Her medical history also included arterial hypertension and bilateral varices along both great saphenous veins, but without oedema, skin dyschromia or phlebostatic ulcers. Physical examination showed abnormal bilateral pulsatile groin swelling, with holosystolic thrill and pulsating varices along the entire course of the great saphenous veins. Cardiac auscultation showed severe tricuspid insuffi ciency, although she was still in class 1 of the New York Heart Association (NYHA) classifi cation system. Doppler sonography showed bilateral incontinence of the saphenofemoral junction and the entire course of the great saphenous vein, with dilatation of the iliaco-caval segment and the suprahepatic veins associated with hepatomegaly. A reversed arteriallike pulsating fl ow was seen in the veins of the abdomen and of the limbs, and in particular in the great saphenous veins. Neither arteriovenous fi stula nor an apparent pulsatile fl ow transmitted by an artery was detected. The arterial trunks were normal. Transthoracic echocardiography showed an ejection fraction of 55%, confi rming the presence of severe tricuspid insuffi ciency (fi gure), with dilatation of the tricuspid annulus (44 mm), the inferior vena cava (39 mm), and the suprahepatic veins with reverse systolic fl ow. On the basis of clinical and sonography fi ndings, we diagnosed severe tricuspid insuffi ciency with reper cussions on the Lancet 2011; 378: 2138

Contrast-Enhanced Sonographic Follow-up After Stenting of Visceral Artery Aneurysms

We report 2 cases of exclusion of visceral artery aneurysms. The first was a common hepatic artery aneurysm treated with a multilayer stent; the second was a celiac trunk aneurysm excluded by a covered stent. Computed tomographic angiography was performed at regular intervals after each procedure, together with echo color Doppler imaging and contrast‐enhanced sonography. Computed tomographic angiography and contrast‐enhanced sonography were able to detect endoleaks in both patients and the related inflow vessel; moreover, diameter measurements of the sacs were identical. In our preliminary experience, contrast‐enhanced sonography appeared to be as accurate as computed tomographic angiography after endovascular visceral artery aneurysm exclusion.
