Objective: To analyze the experience with diagnosis and surgical treatment of visceral artery aneurysms (VAAs).
Methods: From June 2003 to December 2008, 8 patients (2 male and 6 female) with 9 VAAs underwent surgical treatment. Mean age was 49 years (ranged from 30 to 72 years). The site of aneurysmal disease was splenic artery in 4 cases, superior mesenteric artery in 2 cases, renal artery in 2 cases (3 aneurysms). In 1 patient of splenic artery aneurysm, portal vein hypertension coexisted. All the VAAs of preoperative diagnostic workup consisted of a ultrasound, computed tomography (CT) scan, and digital subtraction angiography. Six patients were operated on and two patients was treated with endovascular procedures. Only one small VAAs was treated with follow-up.
Results: No deaths or major complications occurred in the perioperative period. All the patients remained symptom free during a follow-up of 26.5 months (ranged from 2 to 60 months). Follow-up consisted of clinical and ultrasound scan examinations or CT scan at 1 and 6 months, and yearly thereafter.
Conclusions: Aggressive approach to the treatment of VAAs is essential. Elective open surgical treatment and an endovascular procedure of visceral artery aneurysms are both safe and effective, and offers satisfactory early and long term results. There is some evidence that small (< 2 cm) and asymptomatic VAAs may be safely observed.

The management of visceral artery aneurysms is evolving with endovascular coiling and covered stent placement used as alternatives to open repair. Celiac artery occlusion or compression complicates ablative endovascular management. The purpose of this report was to discuss the etiology of this uncommon phenomenon and describe a novel hybrid approach to treatment.

Background: With increasing early-stage non-small cell lung cancer (NSCLC) diagnoses, sublobar resections including segmentectomy and wedge resection have become commonly used in clinical settings. The success of lung segment surgery hinges on the accurate identification of intersegmental planes (ISPs), which is typically achieved by the modified inflation-deflation method; however, this technique is associated with a prolonged duration for identifying ISP. The "partial pressure of oxygen control method" represents an optimization of the inflation-deflation technique, designed to facilitate rapid identification of ISP during surgical procedures.

Background: Magnetic particle imaging (MPI) allows for radiation-free visualization of tracers without background signal. With the first human-sized interventional MPI scanner being recently developed, the aim of the present study was to test its performance for guiding of endovascular procedures in a realistic perfusion model.
Methods: Three fresh-frozen cadaveric legs were prepared to establish continuous circulation in the superficial femoral artery via introducer sheaths in the inguinal and infragenicular region.

Purpose: This study aims to evaluate the safety and efficacy of the Derivo peripher and Derivo 2 Embolization Device Flow Diverter Stents (DEDs, Acandis GmbH) in treating visceral aneurysms.
Materials And Methods: This multicentric registry with core-lab evaluation involves 29 Italian Interventional Radiology and Vascular Surgery units, targeting 100 patients. Inclusion criteria include visceral artery aneurysms without signs of rupture and adherence to correct DED stent sizing and anticoagulant and antiplatelet protocols.

Background: Surgical resection is a frontline management option for early-stage non-small cell lung cancer (NSCLC). Evolving techniques may be refining patient outcomes. This study compares the long-term survival of patients undergoing lobectomy for a primary NSCLC between video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT).
