Coronary artery fistulas: symptoms may not correlate to size. An emblematic case and literature review
2015
<p>Coronary artery fistulas are rare anatomic abnormalities of the coronary arteries present in 0.002% of the general population and represent 14% of all anomalies of coronary arteries. Their clinical relevance focuses mainly on the mechanism of "coronary steal phenomenon”, causing myocardial functional ischemia even in the absence of stenosis, hence common symptoms are angina or dyspnea. Small size fistulas are mostly asymptomatic and have excellent prognosis if managed medically with regular follow-up consisting also in echocardiography every 2-5 years. Big-sized and symptomatic fistulas, on the contrary, should undergo invasive closure, either with a transcatheter approach or with …
Endovascular treatment of spontaneous isolated abdominal aortic dissection
2016
Isolated abdominal aortic dissection is a rare clinical disease representing only 1.3% of all dissections. There are a few case series reported in the literature. The causes of this pathology can be spontaneous, iatrogenic, or traumatic. Most patients are asymptomatic and symptoms are usually abdominal or back pain, while claudication and lower limb ischemia are rare. Surgical and endovascular treatment are two valid options with acceptable results. We herein describe nine cases of symptomatic spontaneous isolated abdominal aortic dissection, out of which four successfully were treated with an endovascular approach between July 2003 and July 2013. All patients were men, smokers, symptomati…

STUDIO SPERIMENTALE SU PANCREAS DI MAIALE PER L’OTTENIMENTO DI CELLULE PRODUCENTI INSULINA
2014
L’obiettivo del mio studio è stato quello di standardizzare delle tecniche per prelevare, mantenere e transdifferenziare la componente sia esocriche sia endocrine del pancreas in cellule producenti insulina; per poter realizzare tale lavoro sono state seguite diverse fasi. Nella fase preliminare furono prelevate e trans-differenziate cellule provenienti dal dotto di Wirsung di maiale in cellule-ß producenti isulina. Nella seconda fase le ß-cellule furono ottenute dalla componente esocrina di pancreas in toto di maiale dopo exsaguinazio e con l’impiego di due diverse soluzioni di conservazione, al fine di valutare quale delle due potesse mantenere meglio l’organo e potesse dare una successiv…
Composite femoro-tibial bypass as alternative solution in complicated revascolarization: Case report
2021
Introduction Peripheral Arterial Disease (PAD) in diabetic patients is a significant cause of Morbility. Long arterial occlusion in patient previously treated can require unusual and complex solution. Herein we report a case of complicated bypass in diabetic patient with history of bypass for bilateral popliteal aneurysm. Presentation of case A 51-year-old male, smoker, with hypertension and diabetes mellitus was referred to our hospital for rest pain in left limb and peripheral cyanosis. Ultrasound doppler (US) showed an occlusion after common femoral artery with patency of Anterior-tibial artery (ATA) two centimeters after the origin. The unavailability of adequate autologous conduit nece…
Type 1A endoleak detachable coil embolization after endovascular aneurysm sealing: Case report
2021
Introduction Endovascular aneurysm sealing (EVAS) with the Nellix system was introduced to reduce endovascular aneurysm repair (EVAR) perioperative complications, especially endoleaks. Herein we report a case of successful type 1A endoleak managed with detachable coils embolization after EVAS. Presentation of case A 77-year-old male was referred for abdominal pain. The angio-CT scan confirmed the previous EVAS procedure and showed a type Is2 endoleak below the right renal artery resulting in a 2.5 cm aortic blister with contrast medium filling the space between the aortic wall and the endobags. The patient was considered unfit for conventional open surgery and an endovascular approach with …
Surgical Treatment of Coledochal Cyst Associated with an Aberrant Posterior Hepatic Duct: Report of a Case and Brief Literature Review
2011
Choledochal cysts (CCs) are rare congenital cystic or fusiform dilatations of the biliary tree that can involve the extrahepatic and/or intrahepatic biliary tree. We report a case of huge type I CC associated with an aberrant posterior hepatic duct. A 52-year-old man presented with a 3-week history of upper right abdominal pain and jaundice and serologic sign of obstructive jaundice. Ultrasonography (US), magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography were performed with the diagnosis of CC type I according to the classification of Alonso-Lej and Todani-Watanabe. The indication for surgical resection was posed. The cyst was completely resected…
