No surgery without previous compression ultrasound in patients with a superficial venous thrombosis: A case of massive paradoxical embolism.
We report a case of a LLSVT complicated with a massive bilateral PE and an ischemic cerebral stroke, occurring immediately after a varicose vein surgery. Venous ultrasonography of the lower limbs must be systematically performed in case of LLSVT, in order to evaluate the presence of an associated LLDVT. A rigorous diagnostic and therapeutic approach is the only way to optimize the treatment of this disorder, and to avoid the occurrence of dramatic venous thromboembolic complications.

Renovascular hypertension: A report of 21 cases.
Abstract Renovascular hypertension (RVH) is among the most common forms of secondary hypertension. We studied 21 patients (eight male and 13 female) with RVH who were encountered during a period of 16 years. The average age of the patients was 34.75 years. Trans-renal Doppler ultrasound confirmed the diagnosis of renovascular stenosis (RAS) as the cause of RVH in 95% of the patients. Computed tomography angiography was performed in ten cases, which confirmed the diagnosis in all these cases. Magnetic resonance angiography was performed in only three patients. Renal scintigraphy was performed in 11 patients, with D...

MRI-guided Sonothrombolysis of Rabbit Carotid Artery
The potential of magnetic resonance imaging–guided focused ultrasound (MRgFUS) combined with the thrombolytic drug recombinant tissue plasminogen activator (rt-PA) to dissolve clots in the carotid of a New Zealand rabbit in vivo is evaluated. A spherically focused transducer of 5-cm diameter, focusing at 10 cm and operating at 1 MHz, was used. A pulsed ultrasound protocol was used that maintains a tissue temperature increase of less than 1°C in the clot (called safe temperature). MRgFUS has the potentials to dissolve clots that are injected in the carotid of rabbits in vivo. It was found that the time needed for ope...

Towards Effective and Safe Thrombolysis and Thromboprophylaxis: Preclinical Testing of a Novel Antibody-Targeted Recombinant Plasminogen Activator Directed Against Activated Platelets.
CONCLUSIONS: Targeting of scuPA to activated GPIIb/IIIa allows effective thrombolysis and the potential novel use as a fibrinolytic agent for thromboprophylaxis without bleeding complications. PMID: 24508759 [PubMed - as supplied by publisher]

Posterior transverse plication of the internal carotid artery to correct for kinking
Conclusions: Although the indications for additional shortening procedures following CEA need to be defined, in this small series, PTP as an additional shortening procedure of the ICA following CEA seems feasible and safe with no additional periprocedural risk for narrowing at the plicature or thrombosis of the endarterectomy plane. However, restenosis at the plicature may hamper the long term benefit of carotid reconstruction.

Coagulation management with factor concentrates in liver transplantation: a single-center experience.
CONCLUSION: In LT, ROTEM-guided treatment with fibrinogen concentrate and/or PCC did not appear to increase the occurrence of thrombosis and ischemic events compared to patients who did not receive these concentrates. PMID: 24827116 [PubMed - as supplied by publisher]

In Vitro and In Vivo Evaluation of a Magnetic Resonance Imaging–guided Focused Ultrasound System for Dissolving Clots in Combination with Thrombolytic Drugs
Conclusions: The MRgFUS technique was proven successful in dissolving clots in vitro and in vivo. It was found that the volume of dissolved clot increases with acoustic intensity and beam size and decreases with frequency. With this system, it was possible to push ultrasound through a plastic phantom skull using a .5 MHz transducer. The beam of ultrasound through the phantom skull was monitored using the MRI technique of fast spoiled gradient. Finally, the thrombus in the in vivo model (ear artery) was successfully destroyed with the therapeutic protocols investigated in the in vitro models. This study shows that FUS ...

A Traveling “Spot Sign” in Recurrent Amaurosis Fugax and Central Retinal Artery Occlusion
In conclusion, this case report describes a single case of repeated amaurosis fugax and deterioration to CRAO via embolization into the central retinal artery and consecutive downstream dislodgment. It emphasizes that ultrasound may render valuable diagnostic information in patients with acute central retinal artery embolization toward its embolic etiology and its risk of subsequent deterioration.

Arterial Closure Devices for Treatment of Inadvertent Large-Caliber Catheter Insertion Into the Subclavian or Carotid Artery: A Case Series of Five Patients
CENTRAL VENOUS CATHETERIZATION is a common procedure in today`s medicine. Iatrogenic complications occur in up to 34% of catheter placements including 5% of arterial puncture. A variety of complications by arterial puncture have recently been described, including airway obstruction, pseudoaneurysms, arteriovenous fistulas, and even stroke caused by arterial thrombosis or embolization. Although 2-D ultrasound assisted insertion of large central venous catheters may reduce adverse events, it might not be available in an emergency setting, and the use of ultrasound guidance requires training. Depending on anatomic localizatio...

Venous thromboembolism in children with acute lymphoblastic leukemia
Abstract Venous thromboembolism (VTE) occurs in 0.95–36 % of children with acute lymphoblastic leukemia almost exclusively during chemotherapy. It is most commonly associated with concurrent l-asparaginase and steroid therapy, central venous line use, and inherited thrombophilia. Clinical manifestations regarding the location of VTE include central nervous system thrombosis (sinus venous thrombosis, cerebral infarct/stroke), upper-/lower-limb deep venous thrombosis, pulmonary embolism, and right atrial/intracardiac and superficial venous thrombosis and can be both symptomatic and asymptomatic. The majority of ...

Heme Oxygenase-1 Gene Promoter Microsatellite Polymorphism Is Associated With Progressive Atherosclerosis and Incident Cardiovascular Disease.
CONCLUSIONS: This study found a strong association between the HO-1 variable number tandem repeat polymorphism and cardiovascular disease risk confined to subjects with a high number of repeats on both HO-1 alleles and provides evidence for accelerated atherogenesis and decreased antioxidant defense in this vascular high-risk group.

Computed tomography angiography vs 3 T black-blood cardiovascular magnetic resonance for identification of symptomatic carotid plaques
Conclusions: Bb-CMR is superior to MDCTA at identifying symptomatic carotid plaques, while MDCTA offers high specificity at the cost of low sensitivity. Results were only slightly improved over bb-CMR alone when combining both techniques.

P-020 Emergent Carotid Artery Stenting with or without Intracranial Tandem Occlusion Lesions Following Carotid Endarterectomy
Conclusion Emergent endovascular evaluation in the setting of acute post CEA thrombosis is a safe and timely treatment option, with the benefit of detecting and treating embolic intracranial lesions. More investigation is necessary to define the role of immediate angiography and intervention in this rare surgical complication.
