This study describes the risk of thrombotic and hemorrhagic complications, both intraoperatively, and up to 1-month following visceral transplantation. Data from 48 adult visceral transplants performed between 2010-2017 were retrospectively studied (32 multivisceral (MVTx); 10 isolated intestine; 6 modified-MVTx). Intraoperatively, intracardiac thrombosis (ICT)/pulmonary embolism (PE) occurred in 25%, 0% and 0% of MVTx, isolated intestine and modified MVTx, respectively, and was associated with 50% (4/8) mortality...

BACKGROUND/OBJECTIVES: Acute pancreatitis (AP) progresses to necrotizing pancreatitis in 15% of cases. An important pathophysiological mechanism in AP is third spacing of fluids, which leads to intravascular volume depletion. This results in a reduced splanchnic circulation and reduced venous return. Non-visualisation of the portal and splenic vein on early computed tomography (CT) scan, which might be the result of smaller vein diameter due to decreased venous flow, is associated with infected necrosis and mortality in AP...

Antithrombin [AT] is the main inhibitor for activated plasma coagulation serine esterases, inhibiting thrombin, Factors Xa and IXa, but also Factors XIIa, XIa, VIIa, kallicrein, and plasmin. Its activity is highly enhanced by heparin, through binding to the pentasaccharide sequences, for inhibition of all coagulation proteases, except thrombin, which inhibition requires its additional binding to the heparin polysaccharide chain. However, AT is the major inhibitor of thrombin in the blood circulation. Congenital or acquired deficiencies of AT expose affected patients to an increased risk of developing unprovoked and recurrent thrombo-embolic diseases...

Thromboses of the superior and inferior vena cava, either isolated or associated with distal deep venous thrombosis, are uncommon, but confer potentially serious morbidity and mortality. Incidence is increasing, especially with the prominence of intravascular devices. The range of treatment options is also expanding to include medical management, surgery, and endovascular techniques which are now frequently considered first line therapy due to lower reintervention rates and decreased periprocedural morbidity...

BACKGROUND: Thrombomodulin (TM) is a promising therapeutic natural anti-coagulant, which exerts the effects to control disseminated intravascular coagulation. However, little is known whether TM on micro-vessels could play an important role in the regulation of intimal hyperplasia. We investigated the vessel-protective effect of TM in the survival of fully major histocompatibility complex (MHC)-mismatched murine cardiac allograft transplantation. METHODS: CBA recipients transplanted with a C57BL/6 heart received intraperitoneal administration of normal saline or 0...

RATIONALE: The acute respiratory distress syndrome (ARDS) is a devastating illness with limited therapeutic options. A better understanding of early biochemical and immunological events in ARDS could inform the development of new preventive and treatment strategies. OBJECTIVE: To determine select peripheral blood lipid mediator and leukocyte responses in patients at-risk for ARDS. METHODS: Patients at risk for ARDS were randomized as part of a multicenter, double-blind clinical trial of aspirin versus placebo (LIPS-A; NCT01504867)...

PURPOSE OF REVIEW: Atherosclerotic plaque deposition within the coronary vessel wall leads to arterial stenosis and severe catastrophic events over time. Identification of these atherosclerotic plaque components is essential to pre-estimate the risk of cardiovascular disease (CVD) and stratify them as a high or low risk. The characterization and quantification of coronary plaque components are not only vital but also a challenging task which can be possible using high-resolution imaging techniques...

Intrauterine transfusion is the most common and successful intrauterine procedure for the treatment of fetal anemia due to red cell alloimmunization. Fetal intracranial hemorrhage is a very rare complication of intrauterine transfusion in patients with Rh(D) alloimmunization and it has been demonstrated only in a few case reports in the literature. Herein, we described a case of grade IV intraventricular hemorrhage that was diagnosed following the first intrauterine transfusion and reviewed the literature about the fetal intracranial hemorrhage that occurred after intrauterine intravascular transfusion procedure...

Formation of tumor thrombus is an occasional manifestation of renal cell carcinoma (RCC). Intravascular invasion of the renal vein and thereafter the inferior vena cava (IVC) might in very rare cases extend into the cardiac chambers. The subtle course and symptoms of such cases alongside with the engagement of vital anatomical structures marks them as a diagnostic and therapeutic challenge. Aggressive surgical intervention has proven to be critical for survival rates in such cases; however total synchronous resection remains a challenge for the surgical team and a debate for the medical community...

we herein report a rare case of methotrexate (MTX)-associated intravascular large B-cell lymphoma (IVLBCL) in a man with rheumatoid arthritis. Two episodes of a fever of unknown origin accompanied by elevated levels of serum lactate dehydrogenase and the soluble interleukin-2 receptor occurred within a year, so the patient was suspected of having an MTX-associated lymphoproliferative disorder. His clinical symptoms resolved after the cessation of MTX. However, after treatment with iguratimod, another disease-modified anti-rheumatic drug, markedly similar symptoms recurred, and random skin biopsies resulted in a diagnosis of IVLBCL...

Little data are available on the accuracy of phase-contrast magnetic resonance imaging (PC-MRI) velocity mapping in the vicinity of intravascular metal stents other than nitinol stents. Therefore, we sought to determine this accuracy using in vitro experiments. An in vitro flow phantom was used with 3 stent types: (1) 316L stainless steel, (2) nitinol self-expanding, and (3) platinum-iridium. Steady and pulsatile flow was delivered with a magnetic resonance imaging-compatible pump (CardioFlow 5000, Shelley Medical, London, Ontario, Canada)...

BACKGROUND: Symmetrical peripheral gangrene is characterized as acral (distal extremity) ischemic limb injury affecting two or more extremities, without large vessel obstruction, typically in a symmetrical fashion. Risk factors include hypotension, disseminated intravascular coagulation, and acute ischemic hepatitis ("shock liver"). In contrast, venous limb gangrene is characterized by acral ischemic injury occurring in a limb with deep vein thrombosis. Both symmetrical peripheral gangrene and venous limb gangrene present as acral limb ischemic necrosis despite presence of arterial pulses...

Due to significant improvements in morbidity and mortality, surgery with curative intent is now the standard of care for patients with colorectal liver metastases who are surgical candidates. As a result, highly accurate preoperative per-lesion diagnosis is crucial. However, in some instances, this remains limited with standard techniques, including magnetic resonance imaging (MRI) with conventional contrast agents. Delayed retention of contrast of fibrotic liver metastases on MRI with extracellular contrast agents may mimic the late retention of contrast in hemangiomas and represent a diagnostic pitfall that limits diagnosis...

REVIEW
D L Clarke
Feline ureteral obstructions are an increasingly recognised and challenging diagnostic and management problem. Many cats with ureteral obstructions are critically ill at the time of diagnosis, especially if there is dysfunction of the contralateral kidney. They may present with varying severities of acute kidney injury, electrolyte disturbances, and may have comorbidities such as heart disease that complicate perioperative and long-term management. Medical management, which may consist of rehydration and restoration of intravascular volume with intravenous fluid therapy, osmotic diuresis, ureteral muscle relaxation, and antimicrobials for infection, is important in feline ureteral obstruction patients...

Adeno-associated virus (AAV) has provided the gene therapy field with the most powerful in vivo gene delivery vector to realize safe, efficacious, and sustainable therapeutic gene expression. Because many clinically relevant properties of AAV-based vectors are governed by the capsid, much research effort has been devoted to the development of AAV capsids for desired features. Here, we combine AAV capsid discovery from nature and rational engineering to report an AAV9 capsid variant, designated as AAV9.HR, which retains AAV9's capability to traverse the blood-brain barrier and transduce neurons...

The ability to measure the elastic properties of plaques and vessels would be useful in clinical diagnoses, particularly for detecting a vulnerable plaque. This study demonstrates the feasibility of the combination of intravascular ultrasound (IVUS) and acoustic radiation force elasticity imaging for detecting the distribution of stiffness within atherosclerotic arteries ex vivo . A dual-frequency IVUS transducer with two elements was used to induce the propagation of the shear wave (by the 8.5 MHz pushing element) which could be simultaneously monitored by the 31 MHz imaging element...
