RESUMEN
Catheter-related thrombosis (CRT) is a relatively frequent and potentially fatal complication arising in patients with cancer who require a central catheter placement for intravenous treatment. In everyday practice, CRT remains a challenge for management; despite its frequency and its negative clinical impact, few data are available concerning diagnosis and treatment of CRT. In particular, no diagnostic studies or clinical trials have been published that included exclusively patients with cancer and a central venous catheter (CVC). For this reason, many questions regarding optimal management of CRT remain unanswered. Due to the paucity of high-grade evidence regarding CRT in cancer patients, guidelines are derived from upper extremity DVT studies for diagnosis, and from those for lower limb DVT for treatment. This article addresses the issues of diagnosis and management of CRT through a review of the available literature and makes a number of proposals based on the available evidence. In symptomatic patients, venous ultrasound is the most appropriate choice for first-line diagnostic imaging of CRT because it is noninvasive, and its diagnostic performance is high (which is not the case in asymptomatic patients). In the absence of direct comparative clinical trials, we suggest treating patients with CRT with a therapeutic dose of either a LMWH or a direct oral factor Xa inhibitor, with or without a loading dose. These anticoagulants should be given for a total of at least 3 months, including at least 1 month after catheter removal following initiation of therapy.

Many patients with cancer require palliative care at some stage and the vast majority of people followed in palliative care are cancer patients. Patients with cancer are at high risk of venous thromboembolism (VTE), and this is particularly true during the advanced palliative phase when mobility is limited or absent. Patients with cancer in palliative care are at higher bleeding risk compared to non-cancer patients. Decisions to treat VTE or withhold anticoagulation for these patients have proven to be difficult and depend largely on an individual clinician's judgment. For this reason, we have developed a consensus proposal for appropriate management of cancer-associated thromboembolism (CAT) in patients in palliative care, which is presented in this article. The proposal was informed by the recent scientific literature retrieved through a systematic literature review. In cancer patients in advanced palliative care, the benefit/risk ratio of anticoagulation seems unfavourable with a higher haemorrhagic risk than the benefit associated with prevention of CAT recurrence and, above all, in the absence of any benefit on quality of life. For this reason, we recommend that patients should be prescribed anticoagulants on a case-by-case basis. The choice of whether to treat, and with which type of treatment, should take into account anticipated life expectancy and patient preferences, as well as clinical factors such as the estimated bleeding risk, the type of VTE experienced and the time since the VTE event.
RESUMEN
Coronavirus disease 2019 (COVID-19) is associated with an increase in venous thrombotic and cardiovascular (CV) events has been reported during hospitalization. No systematic ultrasound follow-up to evaluate sequelae was ever that took place carried out prospectively associated with the evaluation of CV morbidity-mortality at 3 months post-discharge. Consecutive patients hospitalized for COVID-19 in the Amiens-Picardie University Hospital between 1st February and 31st August 2020 were included. The primary objective was the thrombosis incidence at 3 months after hospital discharge. Thrombosis was defined as either venous thromboembolism (VTE) or a CV event (CVE: myocardial infarction (MI), stroke or peripheral arterial disease). A secondary objective was to determine the risk factors for thrombotic events. We included 498 patients (279 men; 56%) of median age 66 (55-76) years. The primary composite outcome occurred in 27 patients (5.4%); 19 patients (3.8%) presented a CVE (stroke, n = 5; MI, n = 9; and peripheral arterial disease, n = 5). Two patients (0.8%) presented VTE. Six patients (1.2%) died. In multivariate analysis, a previous CVE was associated with thrombosis (OR 3.11; 95% CI 1.17-8.24). COVID-19 was significantly associated with thrombotic events post hospital discharge. Special attention should be given to CVE in the follow-up of patients with a previous thrombotic event.
RESUMEN
The OPTIMEV (OPTimisation de l'Interrogatoire dans l'évaluation du risque throMbo-Embolique Veineux) study has provided some important and innovative information for the management of lower extremity isolated distal deep vein thrombosis (distal DVT). Indeed, if distal deep-vein thrombosis (DVT) therapeutic management is nowadays still debated, before the OPTIMEV study, the clinical relevance of these DVT itself was questioned. Via the publication of 6 articles, between 2009 and 2022, assessing risk factors, therapeutic management, and outcomes of 933 patients with distal DVT we were able to demonstrate that: - When distal deep veins are systematically screened for suspicion of DVT, distal DVT are the most frequent clinical presentation of the venous thromboembolic disease (VTE). This is also true in case of combined oral contraceptive related VTE. - Distal DVT share the same risk factors as proximal DVT and constitute two different clinical expressions of the same disease: the VTE disease. However, the weight of these risk factors differs: distal DVT are more often associated with transient risk factors whereas proximal DVT are more associated with permanent risk factors. - Deep calf vein and muscular DVT share the same risk factors, short and long-term prognoses. - In patients without history of cancer, risk of unknown cancer is similar in patients with a first distal or proximal DVT. - After 3years and once anticoagulation has been stopped, distal DVT recur twice less as proximal DVT and mainly as distal DVT; However, in cancer patients, prognosis of distal and proximal DVT appear similar in terms of death and VTE recurrence.

Arterial blood flow to the organs of the upper abdomen is provided by the celiac axis (CA) and the superior mesenteric artery (SMA) that communicate between each other via the gastro-duodenal artery, the anterior and posterior pancreatico-duodenal arcades, the branches of the dorsal pancreatic artery and inconsistently, though a supplementary arcade that connects the CA and the SMA (arcade of Bühler). Celiac axis stenosis may or may not have a hemodynamic impact on the splanchnic circulation. Hemodynamically significant CA stenosis can be asymptomatic, or symptomatic with variables clinical consequences. Management depends on whether the mechanism of stenosis is extrinsic or intrinsic. When upper gastrointestinal interventional radiology or surgery is indicated, stenosis can pose technical difficulties or create severe ischemia requiring good understanding of this entity in the planning of operative steps and adapted management. Management of CA stenosis is therefore multidisciplinary and may involve interventional radiologists, gastrointestinal surgeons, vascular surgeons as well as medical physicians. Even though the prevalence of CA stenosis is relatively low (between 5 and 10%) and irrespective of its etiology, surgeons, radiologists and physicians must be aware of it because it can intervene in the management of upper gastrointestinal disease. It must be sought, and treatment must be adapted to each particular situation to avoid potentially severe complications.

Cancer associated thrombosis (CAT) has been demonstrated a long time ago and is a frequent comorbid condition. Some risk factors are well established and related to the treatment of cancer: surgery, chemotherapy, radiation therapy, indwelling catheters. Other risk factors depend on tumour type and patient presentation, in particular pancreatic and brain cancer, bed resting and previous venous thrombosis. With the advances in cancer treatment and care, patients with cancer live longer and experience various therapies, sometimes during a long time. There is a need to better define the incidence and prevalence of CAT in the light of new therapeutic strategies and patient survival. This article focuses on the description of incidence and prevalence of CAT in the literature and on the description of risk factors, traditional but also emerging ones.

Catatonia is defined as a psychiatric syndrome. This syndrome is strongly associated with venous thromboembolism. As a difficult diagnosis in these patients, psychiatrists and vascular physicians should be aware of this association. We report here a clinical case of this association and discuss the diagnosis difficulties and therapeutics options.

Lower extremity peripheral artery disease is a frequent disease. Arterial Doppler waveforms analysis is a key element in vascular medicine, especially to diagnose lower peripheral artery disease. Although Doppler waveforms are often used, descriptions are highly heterogeneous. This review presents the simplified Saint-Bonnet classification that is tought to vascular medicine residents in order to homogenize arterial flow description.
