While benefits of total parenteral nutrition (TPN) are well documented in a wide range of surgical conditions, deaths of two children secondary to mural thrombi from central venous catheters underscore the potential risks of such therapy. With the proven accuracy and widespread availability of echocardiography for diagnosis of mural thrombi, routine surveillance of all patients receiving TPN via central venous catheters is recommended, if fevers are present or if Candida is isolated on blood cultures. While treatment may involve surgical intervention, most mural thrombi will respond to thrombolytic agents. New approaches to long-term venous access are needed to prevent this lethal complication.

Magnetic resonance imaging and pathological findings of aortoiliac thromboembolism with a thoracic aortic mural thrombus in a Japanese Black calf.
J Vet Med Sci

A 24-day-old female Japanese Black calf presented a sudden paraplegia after a history of watery diarrhea. Antemortem magnetic resonance imaging confirmed the suspicion of thrombotic component in the abdominal aorta, without any spinal cord abnormality at the lumbar region. On necropsy, a massive thrombus occupied the lumen from the distal abdominal aorta to the bifurcation of the external iliac arteries.

Acute aortic occlusion (AAO) is a rare and life-threatening condition, mostly secondary to acute thrombosis or embolism. It usually presents as bilateral lower limb ischemia; however, in rare cases, spinal cord infarction might coexist, mimicking cauda equina syndrome. We present a rare case of AAO by saddle embolism of a thoracic aortic mural thrombus.

Central venous catheter-related thrombosis is a frequent non-infectious complication, typically associated with catheter dysfunction and hemodialysis inadequacy. Central venous catheters (CVCs) are categorized into non-tunnelled and tunnelled types, wherein the choice depends on patient's clinical conditions and the diagnostic and therapeutic workup. Tunnelled CVCs (tCVCs) are sought whenever an arteriovenous fistula is unfeasible or as primary access in patients with poor prognosis.

Left ventricular thrombus formation is not an uncommon complication. There are a variety of reasons for this, for example, myocardial infarction, aneurysm formation and hypercoagulability. This usually has different fates; the most serious of which is propagation and embolization causing distal organ dysfunction.

Background: Acute ischemic stroke (AIS) is a complication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We aimed to explore neurovascular imaging patterns in patients with SARS-CoV-2-related AIS.
Methods: We retrospectively analyzed clinical and radiological data of patients hospitalized with AIS and a positive PCR test for SARS-CoV-2 prior to AIS onset.
