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 …
CT imaging findings of abdominopelvic vascular compression syndromes: what the radiologist needs to know.
2020
AbstractAbdominopelvic vascular compression syndromes include a variety of uncommon conditions characterized by either extrinsic compression of blood vessels by adjacent anatomical structures (i.e., median arcuate ligament syndrome, nutcracker syndrome, May-Thurner syndrome) or compression of hollow viscera by adjacent vessels (i.e., superior mesenteric artery syndrome, ureteropelvic junction obstruction, ureteral vascular compression syndromes, portal biliopathy). These syndromes can be unexpectedly diagnosed even in asymptomatic patients and the predisposing anatomic conditions can be incidentally discovered on imaging examinations performed for other indications, or they can manifest wit…
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…
PANCREATICODUODENAL ARTERIES ANEURYSMS: EVALUATION OF FREQUENCY AND ASSOCIATION WITH CELIAC ARTERY STENOSIS DUE TO COMPRESSION BY MEDIAN ARCUATE LIGA…
2019
The aim of the study is to evaluate the prevalence of pancreaticoduodenal arteries (PDA) aneurysms in a large population, and to define possible correlations with celiac artery stenosis due to compression by the median arcuate ligament. Radiological reports of abdominal contrast-enhanced CT scans of 18,180 patients were scrutinized to identify patients with true PDA aneurysms. Two abdominal radiologists classified the aneurysms according to size, location and morphology and scored the presence of celiac artery stenosis due to either median arcuate ligament compression or atherosclerotic disease. Eleven true PDA aneurysms were identified in 10 patients. Nine out of 10 patients had stenosis o…
Iatrogenic lumbar artery pseudoaneurysm after lumbar transpedicular fixation: Case report
2019
Only a few cases of iatrogenic lumbar injury have been reported in the literature. A 58-year-old male with severe back pain was admitted to our department. The patient was qualified for the transpedicular stabilization with interbody fixation at L4/L5 and L5/S1 levels. On the first day after surgery, the patient was mobile and reported significant pain relief. He was discharged the same day. After 2 weeks, the patient returned with severe right lower abdominal pain and radicular pain in his right leg. He was administered to the Neurology Department where the presence of a lumbar muscle hematoma and lumbar artery pseudoaneurysm were discovered. He was transferred to the Vascular Surgery Depa…
Coronary bifurcations - anatomy, physiology and treatment with selected aspects of left main stem bifurcation
2021
Bifurkacja wieńcowa jest miejscem szczególnym w obrębie krążenia wieńcowego. Charakterystyczna anatomia oraz cechy przepływu krwi w złożony sposób wiążą się z rozmieszczeniem blaszek miażdżycowych. Wybór strategii leczenia zmian bifurkacji wieńcowych wymaga szczególnej uwagi, gdyż wszelkie powikłania w tym rejonie narażają na niedokrwienie istotnie większy obszar miokardium niż w przypadku pojedynczego naczynia. Niniejsza publikacja stanowi przegląd podstawowych informacji o anatomii, klasyfikacji oraz kolejnych krokach aktualnie zalecanych technik leczenia przezskórnego zmian bifurkacji wieńcowych, poczynając od kwalifikacji, przygotowania, poprzez wybór stentu, po optymalizację efektu zab…
Mediterranean diet impact on cardiovascular diseases: a narrative review
2017
Cardiovascular disease (CVD) accounts for more than 17 million deaths per year worldwide. It has been estimated that the influence of lifestyle on CVD mortality amounts to 13.7% for smoking, 13.2% for poor diet, and 12% for inactive lifestyle. These results deeply impact both the healthy status of individuals and their skills in working. The impact of CVD on productivity loss accounts for the 24% in total costs for CVD management. Mediterranean diet (MedD) can positively impact on natural history of CVD. It is characterized by a relatively high consumption of inexpensive and genuine food such as cereals, vegetables, legumes, nuts, fish, fresh fruits, and olive oil as the principal source of…

Correlation Between Smoking Paradox and Heart Rhythm Outcomes in Patients With Coronary Artery Disease Receiving Percutaneous Coronary Intervention
2022
BackgroundThe effect of smoking on short-term outcomes among patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) is controversial. However, little is known about the impact of smoking on long-term outcomes in patients with stable coronary artery disease (CAD) who receive PCI.MethodsA total of 2,044 patients with stable CAD undergoing PCI were evaluated. They were divided into two groups according to smoking status (current smokers vs. non-smokers). Baseline characteristics, exposed risk factors, angiographic findings, and interventional strategies were assessed to compare the long-term clinical outcomes between groups. Predictors for myocardial in…
