[Quality standards for ultrasonographic assessment of peripheral vascular malformations and vascular tumors. Report of the french society for vascular medicine. 2018 Update]. / Standards de qualité pour la pratique de l'examen écho-Doppler dans l'étude des malformations et tumeurs vasculaires. Rapport de la Société française de médecine vasculaire (SFMV) : actualisation 2018.

The quality standards of the French Society of Vascular Medicine for the ultrasonographic assessment of vascular malformations are based on the two following requirements: (1) technical know-how: mastering the use of ultrasound devices and the method of examination; (2) medical know-how: ability to adapt the methods and scope of the examination to its clinical indication and purpose, and to rationally analyze and interpret its results. AIMS OF THE QUALITY STANDARDS: To describe an optimal method of examination in relation to the clinical question and hypothesis. To homogenize practice, methods, glossary, and reporting. To provide good practice reference points, and promote a quality process. ITEMS OF THE QUALITY STANDARDS: The 3 levels of examination; their clinical indications and goals. The reference standard examination (level 2), its variants according to clinical needs. The minimal content of the examination report; the letter to the referring physician (synthesis, conclusion and proposal for further investigation and/or therapeutic management). Commented glossary (anatomy, hemodynamics, semiology). Technical bases. Setting and use of ultrasound devices. Here, we discuss ultrasonography methods of using of ultrasonography for the assessment of peripheral vascular malformations and tumors (limbs, face, trunk).

[Pulmonary embolism and sibilant types of chronic obstructive pulmonary disease decompensations]. / Embolie pulmonaire et formes sibilantes des décompensations de bronchopneumopathie chronique obstructive.

Pulmonary Embolism (PE) poses an important diagnostic problem in patients with chronic obstructive pulmonary disease (COPD). Indeed PE may aggravate the already precarious respiratory state of these fragile patients. Moreover, these two conditions share common symptoms: dyspnoea, wheezing, pleural pain, haemoptysis, palpitations and signs of right cardiac insufficiency. In two studies, one retrospective and the other prospective, we investigated the incidence of PE in patients with non-infective exacerbations of their COPD. The retrospective study was carried out over two years and involved 50 COPD patients with non-infective respiratory exacerbations. In this population, 10 patients out of 50 (20%) had a documented PE. No predictive factor was identified. The prospective study was conducted over one year and COPD patients admitted to hospital with exacerbations were included in the study if they had a positive D-dimer blood test and no evidence of acute respiratory infection. 31 patients were studied with Doppler ultra-sound examination of the legs and a lung perfusion scan. The presence or absence of PE was determined and the two groups were compared. 9 patients out of 31 (29%) had a documented PE. Six of these nine patients had a deep venous thrombosis (DVT). Two predictive factors of PE were identified: existence of a DVT and a significant fall in PaO(2) from baseline state (DeltaPaO(2) > 22 mmHg). We conclude that PE is a frequent (20 to 30%) of non-infective respiratory decompensation in COPD patients. Faced with an unexplained respiratory exacerbation in these patients, a lung perfusion scan should be routinely undertaken to rule out a PE when the D-dimers are positive.

Treatment of popliteal arterial aneurysm using a superficial femoral artery autograft.

The usefulness of aggressive surgical management of popliteal arterial aneurysm is now widely accepted. Reconstruction is usually performed using either prosthesis or saphenous vein autograft. Autografts are preferable but not always possible because of problems of availability and congruence. An alternative conduit for cases involving lesions spanning the articular midline of the knee is the superficial femoral artery. From 1993 to 1998, we used superficial femoral artery autografts to treat a total of 18 aneurysms in 12 patients. All patients were male with a mean age of 66 years (range, 42 to 75). Fourteen aneurysms were treated during elective procedures, including four in combination with aortic repair. The remaining four were treated on an emergency basis. Exposure was achieved via the internal medial route in all cases. Treatment consisted of exclusion or aneurysmorraphy. The mean length of the autograft harvested from the ipsilateral thigh was 10.2 cm (range, 6-18). The harvested graft was replaced by a PTFE prosthesis. Our results show that superficial femoral artery autografts are a suitable alternative for two indications: for patients with small aneurysms located in the middle of the popliteal artery, since autografts provide excellent congruence, and for patients with no other useable donor vein or concurrent deep venous thrombosis.

[Effect of meteorological variations on the emergence of deep venous thrombosis of the leg]. / Influence des variations météorologiques sur la survenue de thrombose veineuse profonde des membres inférieurs.

INTRODUCTION: Recent articles have established a significant relationship between metereology variables and the development of vascular disease. We performed a retrospective study to determine relationships between the development of deep vein thrombosis in the lower limb and certain meteorology variables. MATERIALS AND METHODS: We identified 345 cases of phlebitis in 1995. We studied the distribution of the number of venous thrombosis per day, per month and per season. We compared certain meteorological data (atmospheric pressure, temperature, mean hygrometery) for days with and days without venous thrombosis and the atmospheric variations during the 48 hours prior to venous thrombosis. RESULTS: There was a significant relationship (p < 0.004) between the mean number of cases of phlebitis recorded per day and season with winter predominating. On days when phlebitis occurred, the atmospheric pressure was significantly lower (p < 0.05). The number of thrombotic events was significantly different on days when the variation was greater than 10 hectopascals than on days when the variation was less than 10 hectopascals (p < 0.05). CONCLUSIONS: In our study, deep vein thrombosis of the lower limb was significantly associated with certain meteorology variables. Prospective multicentric studies are needed to confirm these relationships.
