Carotid artery stenting with contralateral carotid occlusion in a rare aortic arch configuration

We present the case of a 47-year-old man admitted to our department with an episode of aphasia. Duplex scan showed an occluded right internal carotid artery and severe left internal carotid artery stenosis. Contrast-enhanced computer tomography demonstrated a common trunk for both common carotid arteries anterior to the trachea and aberrant right subclavian artery posterior to the esophagus. The patient was considered to be a high risk for carotid endarterectomy and, consequently, we performed stenting of the left carotid artery. To our knowledge, this is the first case reporting the combination of these two aortic arch anomalies and the concomitant endovascular treatment of atherosclerotic carotid stenosis

Laparoscopic treatment of abdominal unicentric castleman's disease: a case report and literature review.

BACKGROUND: Castleman's disease is a rare lymphoproliferative disorder of unknown etiology that most commonly presents as a mediastinal nodal mass. It is exceptionally uncommon for Castleman's disease to present in the mesentery and, only 53 cases have ever been described in the literature. Standard treatment for this lymphoproliferative disorder involving a single node is a complete "en bloc" surgical resection which has proven to be a curative approach in almost all cases without recurrence after 20 years of follow up. All 53 reported cases of mesenteric Castleman's disease, except one, were treated with laparotomy. CASE PRESENTATION: We report on a case of mesenteric Castleman's disease localized in the mesentery which is the second reported case if its kind and was treated by a laparoscopic-assisted procedure. Our female patient had an uneventful postoperative course and was discharged in the 5th post-operative day. No signs of recurrence were present as evidenced by physical examination and total body CT scan 24 months after the operation. We compare our case with the other reported cases in which Castleman's disease presented as an isolated mass in the abdomen. CONCLUSION: Although a rare disease, Unicentric Castleman's disease should always be considered when a solid asymptomatic abdominal mass is occasionally presented. The laparoscopic approach (LA) allows for the achievement of better results than open surgery, including a reduction in postoperative pain and length of hospital stay. In cases of masses of an uncertain nature, LA must be considered the last diagnostic tool and the first treatment one

Endograft connector technique to treat popliteal artery aneurysm in a morbid obese patient.

Surgical repair of popliteal artery aneurysm in morbid obese patients poses additional challenges. We report a morbid obese patient who had a 59mm right popliteal artery aneurysm which was successfully treated with the endograft connector technique. This technique was used to perform the distal anastomosis of the below-knee femoro-popliteal bypass. A 10mm Dacron graft was used as a main graft bypass and an 11 mm/10 cm stentgraft as endograft connector. Following the respective tunnel of the Dacron graft, an end-to-side proximal anastomosis was performed at distal femoral artery. The aneurysm exclusion was obtained through a proximal and a distal ligation. Postoperative duplex showed adequate bypass patency. Knee x-rays demonstrated no signs of stent kinking/fractures. The postoperative course was uneventful and the patient was discharged home on fourth day post operative. The six-month computed tomography scan and the 12-month duplex control showed a patent bypass with no signs of stenosis

Mycotic pseudoaneurysms complicating renal transplantation: a case series and review of literature

<p>Abstract</p> <p>Introduction</p> <p>Kidney transplantation can be complicated by infection and subsequent development of mycotic aneurysm, endangering the survival of the graft and the patient. Management of this condition in five cases is discussed, accompanied by a review of the relevant literature.</p> <p>Case presentations</p> <p>Five patients, three men 42-, 67- and 57-years-old and two women 55- and 21-years-old (mean age of 48 years), all Caucasians, developed a mycotic aneurysm in the region of the anastomosis between renal graft artery and iliac axes. Four patients presented with systemic fever and iliac fossa pain and one presented with hemorrhagic shock. Morphologic investigation by color doppler ultrasonography revealed a pseudoaneurysm at the anastomotic site. A combination of antibiotic therapy, surgery and interventional procedures was required as all kidney transplants had to be removed. No recurrence was recorded during the follow-up period.</p> <p>Conclusions</p> <p>A high index of suspicion is required for the timely diagnosis of a mycotic aneurysm; aggressive treatment with cover stents and/or surgical excision is necessary in order to prevent potentially fatal complications.</p

An evaluation of coronary atherosclerosis using coronary CT in subjects with asymptomatic carotid lesions.

The evaluation of coronary lesions in patients with asymptomatic carotid plaque represents a very promising line of research to assess cardiovascular risk and the possible implementation of a more aggressive prevention therapy. METHODS: In this study we enrolled 102 patients with intermediate to high cardiovascular risk but no history of coronary artery disease. The first group, consisting of 51 patients, underwent a Coronary CT scan (CCT-group) as well as carotid ultrasonography. The second group, also consisting of 51 patients, underwent coronary angiography (CA) and carotid ultrasonography. RESULTS: The absence of a statistically significant difference between the involvement of both coronary and carotid sites, assessed by CCT and CA, confirms the role of coronary CT as a useful method in the preclinical evaluation of cardiovascular risk. In the CCT group, the correlation between atherosclerosis of carotid artery and coronary disease, as well as between the mean carotid intimal medial thickness and the number of involved coronary vessels, and between the maximum values of carotid plaque and the presence of coronary artery stenosis > 50%, were statistically significant. The Agatson calcium score was also statistically associated with carotid plaque size. CONCLUSION: The imaging biomarkers have a key role in the evaluation of subclinical atherosclerotic disease. Moreover, carotid ultrasound examination and a CT-scan of coronary arteries, in a particular sub-group of patients with intermediate to high cardiovascular risk, can play a crucial role to assess the preventive therapeutic strategies
