Upper extremity vein thrombosis (UE-VT) are more and more frequent pathologies and yet little studied. The aim is to describe the clinical and ultrasound features, UE-VT-related diseases, and the prevalence of pulmonary embolism (PE) and associated deaths. All UE-VT patients diagnosed by Doppler-ultrasound in Nantes University Hospital, from January 2015 to December 2017, were included retrospectively. UE-VT suspicion patterns, clinical features, UE-VT topography, and prevalence of PE and death were analyzed. Seven hundred and fifty-five UE-VT were analyzed, including 427 deep thrombosis (UE-DVT) and 328 superficial thrombosis (UE-SVT). In 86.2% (n = 651) UE-VT were related to endovascular devices. Among these thrombosis, one third is in connection with a PICC LINE and one quarter with a peripheral venous line. Forty nine percent (n = 370) of the patients had solid neoplasia or hematological malignancies. An inflammatory or systemic infectious context was found in 40.8% (n = 308) of the cases. The most frequently observed clinical sign at the UE-VT diagnosis was edema (28.6%). Among the UE-SVT it was the presence of an indurated cord (33.2%) and among the UE-DVT the indication of the Doppler-ultrasound was mainly a suspicion of infection on endovascular device (35.1%). In 10.6% (n = 80) of the cases the UE-VT were asymptomatic. The most frequently thrombosed veins were brachial basilic veins (16.7% of all thrombosed segments) followed by jugular (13%) and subclavian (12.3%) veins; 61.3% (n = 463) of UE-VT were in the right upper extremity; 63.3% (n = 478) UE-VT were occlusive. The occurrence of PE is 4% and the death rate is 10.2%, mainly related to the severe comorbidities of patients with UE-VT. UE-VT occurs in particular clinical contexts (hematological malignancies, solid cancers, systemic infections) and in the majority of endovascular devices (86.2%). The occurrence of PE is low.

Background: Endovenous interventional procedures can be used in addition to therapeutic anticoagulation to treat deep vein thrombosis in selected patients with proximal vein involvement (vena cava, iliac and/ or common femoral). The aim of this study was to compare venous patency and the post-thrombotic syndrome (PTS) in patients treated with pharmaco-mechanical catheter-directed thrombolysis (PMT) versus recanalization-stenting for PTS after a proximal lower limb deep vein thrombosis. Methods: Between January 2014 and December 2020, this retrospective and monocentric study included patients with very symptomatic acute iliofemoral deep vein thrombosis treated with PMT within 21 days after diagnosis (PMT group) and patients with PTS caused by chronic venous obstruction treated with recanalization and stenting (CRS group).Results: A total of 116 patients were included (26 PMT, 90 CRS). The rate of primary patency was 81.8% (18/22 patients) in the PMT group and 78.4% (69/88) in the CRS group (P>0.99). The rate of venous patency at the last follow-up was 76.9% (20/26) in the PMT group and 82.2% (74/90) in the CRS group (P=0.57).The median number of stents was 2 (range, 0-5) in the PMT group and 3 (range, 0-7) in the CRS group (P<0.001). The median stent length was 150 mm (range, 60-390 mm) and 280 mm (range, 120-820 mm), respectively (P<0.001). The median last Villalta score was 2 (range, 0-10) in the PMT group and 2 (range, 0-21) in the CRS group (P=0.55). The rate of venous claudication at the last follow-up was 19.0% (4/21) in the PMT group and 12.0% (10/83) in the CRS group (P=0.47).Conclusions: In this study, there was no difference in venous patency and in the rate and severity of PTS between the PMT and CRS groups. The number of stent and their length were significantly lower in the PMT group compared with the CRS group.

Upper extremity digital ischaemia (UEDI) is a rare heterogeneous condition whose frequency is 40 times less than that of toe ischaemia. Using a large cohort, the aim of this study was to evaluate aetiologies, prognosis and midterm clinical outcomes of UEDI. All patients with UEDI with or without cutaneous necrosis in a university hospital setting between January 2000 to December 2016 were included. Aetiologies, recurrence of UEDI, digital amputation and survival were analyzed retrospectively. Three hundred twenty three patients were included. UEDI due to cardio-embolic disease (DICE) was the highest occurring aetiology with 59 patients (18.3%), followed by DI due to Systemic Sclerosis (SSc) (16.1%), idiopathic causes (11.7%), Thromboangiitis obliterans (TAO) (9.3%), iatrogenic causes (9.3%), and cancer (6.2%). DICE patients tended to be older and featured more cases with arterial hypertension whereas TAO patients smoked more tobacco and cannabis. During follow-up, recurrences were significantly more frequent in SSc than in all other tested groups ( P < .0001 vs idiopathic and DICE, P = .003 vs TAO) and among TAO patients when compared to DICE patients ( P = .005). The cumulated rate of digital amputation was higher in the SSc group (n = 18) ( P = .02) and the TAO group (n = 7) ( P = .03) than in DICE (n = 2). This retrospective study suggests that main aetiologies of UEDI are DICE, SSc and idiopathic. This study highlights higher frequency of iatrogenic UEDI than previous studies. UEDI associated with SSc has a poor local prognosis (amputations and recurrences) and DICE a poor survival. UEDI with SSc and TAO are frequently recurrent.
