Multiple renal arteries are a common renal vascular variant. A study with 800 kidneys from cadaver donors demonstrated 1% prevalence of quadruple renal arteries.1 During thoracoabdominal aortic aneurysm (TAAA) repair, this anomaly implies longer time of renal ischemia and well-defined reperfusion strategy.2 Acute kidney injury during TAAA repair is a common complication with 6% to 7% incidence.3,4 It can be prevented by histidine-tryptophan-ketoglutarate solution (Custodiol; Dr Franz-K öhler Chemie GmbH, Bensheim, Germany) renal perfusion.

Suprarenal abdominal aortic coarctation (SAAC) is a congenital midaortic syndrome that develops owing to a developmental anomaly in the fusion of the embryonic dorsal aortae. This condition is associated with severe hypertension, which is usually the indication for intervention. Open surgery is the primary treatment and it typically involves thoracoaortic bypass (TAB), and less commonly patch aortoplasty (PA). Bypass to the visceral vessels has also been performed in conjunction with TAB or PA. The majority undergoing intervention for SAAC are children and adolescents; therefore, the benefits of surgical intervention must ...

We present the case of a 46-year-old woman with a presumed diagnosis of multiple unprovoked pulmonary emboli. Her cardiorespiratory function continued to deteriorate despite optimal medical therapy. At surgical thrombectomy she was identified to have an intimal soft tissue lesion arising from the right pulmonary artery. This lesion was subsequently diagnosed as a pulmonary artery sarcoma, a rare neoplasm that carries a poor prognosis. It typically presents at an advanced stage with pulmonary vascular obstruction. Surgical debulking is the mainstay of therapy to restore ventilation perfusion mismatching and relieve right-si...

Michael Deeb, Bo YangBackgroundIt is controversial if extension of aortic dissection into arch branches should be an indication for replacement of the arch and its branches in acute type A aortic dissection.MethodsFrom 2008 to April 2018, 399 patients underwent open repair for an acute type A aortic dissection, and 190 patients had known innominate and/or left common carotid artery dissection without malperfusion syndrome, including no arch ...

ConclusionsFor patients without aortic dissection and who require more than 30 minutes of circulatory arrest, optimal cerebral protection strategies are deep hypothermia with either antegrade or retrograde cerebral perfusion and moderate hypothermia with antegrade cerebral perfusion.

Ex vivo lung perfusion (EVLP) creates a proinflammatory environment leading to deterioration in graft quality which may contribute to posttransplant graft dysfunction. Triptolide has been shown to have a therapeutic potential in various disease states due to its anti-inflammatory properties. Based on this, we investigated the impact of Triptolide on graft preservation during EVLP as well as associated post-transplant outcomes in a rat transplant model.

Every year in Unites States more than 350,000 patients suffer an out of hospital cardiac arrest, with an overall survival at the hospital discharge around 10%.1 The standard treatment of cardiac arrest is the cardiopulmonary resuscitation (CPR) that includes the manual chest compressions which unfortunately, provides a low perfusion state, generating about 25% –33% of the normal cardiac output and for a limited time period.2 In order to restore circulation during cardiac arrest and improve the outcome it has been proposed the use of extracorporeal cardiopulmonary resuscitation (ECPR) in addition to standard treatment.

We report a patient with pituitary macroadenoma who was subjected to stress-MPI study for pre-anesthetic clearance. The post-stress raw image showed the liver radiotracer activity in close approximation to the anteroseptal wall of the left ventricular myocardium, secondary to right hemi-diaphragmatic eventration.
