Critical Limb Ischemia: A Practical Up-To-Date Review.

Critical limb ischemia (CLI) is the most advanced form of peripheral artery disease. It is associated with significant morbidity and mortality and high management costs. It carries a high risk of amputation and local infection. Moreover, cardiovascular complications remain a major concern. Although it is a well-known entity and new technological and therapeutic advances have been made, this condition remains poorly addressed, with significantly heterogeneous management, especially in nonexperienced centers. This review, from a third-level dedicated inpatient and outpatient cardioangiology structure, aims to provide an updated summary on the topic of CLI of its complexity, encompassing epidemiological, social, economical and, in particular, diagnostic/imaging issues, together with potential therapeutic strategies (medical, endovascular, and surgical), including the evaluation of cardiovascular risk factors, the diagnosis, and treatment together with prognostic stratification.

[Asymptomatic Takayasu's arteritis: an incidental diagnosis]. / Arterite asintomatica di Takayasu: una diagnosi occasionale.

We present the case of a 56 years-old female patient that was admitted to our Unit after an incidental observation of bilateral absence of the radial pulses, with impossibility of brachial arterial pressure measurement. The patient reported being completely asymptomatic in occasion of the episode, thus like previously and later on to it. We diagnosed the patient being affected of Takayasu arteritis and adeguate therapy had been undertaken.

An uncommon clinical condition: chronic thrombosis of the inferior vena cava. A case report and review of literature.

The lifetime incidence of deep vein thrombosis (DVT) is approximately 0.1% in general population and even more uncommon in subjects below 40 years of age. Thrombosis of the inferior vena cava (IVC) is an exceptionally rare clinical condition, with etiological factors similar to lower limb DVT. We present a case of post-traumatic chronic obstruction of the IVC in 41 years-old man, caused by a prolonged squatted position, while he was working as a bricklayer. We visited the patient fifteen years after the onset of the first clinical setting showing a severe post thrombotic syndrome, as a consequence of the already diagnosticated thrombosis, involving predominantly the right inferior leg. Thrombophilia screening tests showed patient to be a heterozygous carrier of methylenetetrahydrofolate reductase (MTHFR) gene mutation. Computed tomography (CT) scan confirmed the thrombotic obstruction of the infrahepatic IVC, both common iliac veins, right external and internal iliac veins, with multiple collateral pathways. Because of thrombosis extension, inherited prothrombotic condition and the young age of the patient, we decided to continue life-long oral anticoagulant therapy.

[Appropriateness of prescription of exercise stress test, echocardiography, Holter monitoring and vascular echography]. / L'appropriatezza dei test cardiologici non invasivi. studio osservazionale sull'appropriatezza della prescrizione del test da sforzo, dell'ecocardiogramma, dell'ECG dinamico e dell'ecografia vascolare.

BACKGROUND: The aim of this study was to evaluate the appropriateness of prescription of non-invasive cardiological tests (exercise stress test, echocardiography, Holter monitoring and vascular echography), consecutively performed in our outpatient laboratory during 4 weeks. METHODS: We collected the following data: the appropriateness of prescription (according to the Italian Federation of Cardiology guidelines); test indications; the prescribing physician (cardiologist/non-cardiologist); type of prescription (elective/urgent); clinical utility (useful/useless) and result (normal/abnormal) of each test. RESULTS: We evaluated 960 prescriptions (320 exercise tests; 282 echocardiograms; 158 Holter tests; 200 vascular echographies). Test indications were appropriate (class I) in 37%, doubtfully appropriate (class II) in 39% and inappropriate (class III) in 24% of the cases. The appropriateness was slightly better for vascular echography and echocardiography (class I: 44% and 43%, respectively), markedly worse for exercise test (class I: 27%). The tests were considered useful in 46% and abnormal in 39% of the cases. Cardiologist-prescribed exams resulted more often appropriate (class I: 53 vs 30%; class II: 41 vs 38%; class III: 6 vs. 32%; p = 0.0001), more often useful (74 vs. 34%; p = 0.0001) and more frequently abnormal (43 vs. 37%; p = 0.05), when compared to non-cardiologist-prescribed exams. No differences in appropriateness, utility and test result have been detected between elective and urgent exams. Exercise test, echocardiogram and Holter monitoring resulted more often appropriate and useful when prescribed by cardiologists. CONCLUSIONS: This study confirms that only one third of prescriptions for non-invasive cardiological tests are appropriate. Cardiologist-prescribed exams are more often appropriate, useful and abnormal.

[Acute antineoplastic drug cardiotoxicity: a case report of life-threatening left ventricular failure associated with severe hyperglycemia]. / Cardiotossicità acuta da antineoplastici: descrizione di un caso di grave insufficienza ventricolare sinistra associata a severa iperglicemia.

Anthracyclines represent an established therapy for various hemopoietic and solid tumors; however the cardiotoxicity of these agents continues to limit their therapeutic potential in many cancer patients. Acute life-threatening cardiac toxicity which occurs immediately after a single dose of therapy is very rare under current treatment protocols. This form of toxicity occurs unexpectedly owing to a large variation in individual sensitivity. It may cause transient arrhythmias, hypotension, a pericarditis-myocarditis syndrome, or acute left ventricular failure. We report the case of a 43-year-old woman recently operated on for breast cancer, with acute life-threatening left ventricular failure associated with severe hyperglycemia, occurring a few hours after the first dose of anthracyclines for adjuvant chemotherapy. Severe regional wall motion abnormalities and a significant impaired systolic left ventricular function associated with high creatine phosphokinase-MB and troponin levels were observed. At discharge the regular insulin treatment was interrupted since glycemia was normalized, and complete recovery of the cardiac function was observed 1 month later. Differential diagnosis and the underlying pathogenetic mechanisms are discussed. This life-threatening event is rare, but considering the widespread use of anthracyclines in cancer treatment, it is important for the cardiologist to be aware of the potential acute cardiac toxicity of these agents for early diagnosis and management.
