[Linee guida flebo-linfologiche SIF-SICVE 2016 della Società Italiana di Flebologia e della Società Italiana di Chirurgia Vascolare ed Endovascolare].

Phlebology is not a specialty for its own in Italy. Phlebological patients are treated by vascular and general surgeons, dermatologists, phlebologists, angiologists, internists and even general practitioners. Even tough guidelines present a series of recommendations based on evidence-based medicine, guidelines may also be a tool to unify the diagnostic and therapeutic approach in a vast medical field like phlebology. Since vascular surgeons and phlebologists are particularly involved in phlebology-related pathologies the scientific societies of the Italian Society of Phlebology (SIF) and the Italian Society for Vascular and Endovascular Surgery (SICVE) decided to cooperate for the preparation of phlebo-lymphological guidelines. These guidelines comprehend also an important chapter dealing with the lymphology of the lower extremities; phlebological active physicians are often faced with lymphatic pathologies and a good differential diagnosis can be sometimes very helpful. Sclerotherapy and Surgery as the major therapeutical alternatives are extensively analyzed, but also the compression therapy, the medical and physical therapy are presented under the critical view of evidence based analyses. Separate chapters deal with the treatment alternatives for superficial and deep venous thromboses and the recommendations for the treatment of venous ulcers. The current scientific evidences were confronted with the experiences of Italian specialists and the particular practice and reality in Italy. They represent therefore the actual valid positions and recommendations in Italy which shall be updated regularly.

Favorable effects of carotid endarterectomy on baroreflex sensitivity and cardiovascular neural modulation: a 4-month follow-up.

Carotid surgery variably modifies carotid afferent innervation, thus affecting arterial baroreceptor sensitivity. Low arterial baroreflex sensitivity is a well-known independent risk factor for cardiovascular diseases. The aim of this study was to assess the 4-mo effects of carotid endarterectomy (CEA) on arterial baroreceptor sensitivity and cardiovascular autonomic profile in patients with unilateral carotid stenosis. We enrolled 20 patients (72 ± 8 yr) with unilateral >70% carotid stenosis. ECG, beat-by-beat blood pressure, and respiration were continuously recorded before and 126 ± 9 days after CEA, at rest and during a 75° head-up tilt. Both pharmacological (modified Oxford technique, BRS) and spontaneous (index α, spectral analysis) arterial baroreflex sensitivity were assessed. Cardiovascular autonomic profile was evaluated by plasma catecholamines and spectral indexes of cardiac sympathovagal modulation [low-frequency R-R interval (LFRR), low frequency-to high frequency ratio (LF/HF), high-frequency R-R interval (HFRR)] and sympathetic vasomotor control [low-frequency systolic arterial pressure (LFSAP)] obtained from heart rate and SAP variability. After CEA, both the index α and BRS were higher (P < 0.02) at rest. SAP variance decreased both at rest and during tilt (P < 0.02). Before surgery, tilt did not modify the autonomic profile compared with baseline. After CEA, tilt increased LF/HF and LFSAP and reduced HFRR compared with rest (P < 0.02). Four months after CEA was performed, arterial baroreflex sensitivity was enhanced. Accordingly, the patients' autonomic profile had shifted toward reduced cardiac and vascular sympathetic activation and enhanced cardiac vagal activity. The capability to increase cardiovascular sympathetic activation in response to orthostasis was restored. Baroreceptor sensitivity improvement might play an additional role in the more favorable outcome observed in patients after carotid surgery.
