A rare manifestation of clinical T1 renal tumor with parasitic arterial supply from the superior mesenteric artery.

A 50-year-old man with von Hippel-Lindau syndrome who had undergone repeated tumor enucleation and transcatheter arterial embolization for multiple renal cell carcinomas (RCC) was referred to our hospital for percutaneous cryoablation (PCA) of an RCC of 42 mm in the midpole region of the right kidney. Transcatheter arterial embolization was planned prior to devascularize the RCC and selective angiography revealed parasitic arterial supply to the tumor by the ileocecal artery. Parasitic arterial supply to RCCs, particularly in patients with history of nephron-sparing treatment, can originate even from an intraperitoneal source and may lead to unexpected embolization.

Effect of Angiotensin II on Matrix Metalloproteinase-2 Secretion in Human Umbilical Vein Endothelial Cells.

Matrix metalloproteinase (MMP), which is secreted from vascular cells, is an enzyme-degrading extracellular matrix protein. MMP molecules, including MMP-2, are involved in the destabilization of atherosclerotic plaque and plaque rupture during the development of cardiovascular disease. Angiotensin II (Ang-II), a vascular stimulant associated with cardiovascular disease progression, has been demonstrated to be mainly involved in cardiovascular remodeling of atherosclerosis and cardiac hypertrophy.

Tokyo Guidelines 2018: surgical management of acute cholecystitis: safe steps in laparoscopic cholecystectomy for acute cholecystitis (with videos).

In some cases, laparoscopic cholecystectomy (LC) may be difficult to perform in patients with acute cholecystitis (AC) with severe inflammation and fibrosis. The Tokyo Guidelines 2018 (TG18) expand the indications for LC under difficult conditions for each level of severity of AC. As a result of expanding the indications for LC to treat AC, it is absolutely necessary to avoid any increase in bile duct injury (BDI), particularly vasculo-biliary injury (VBI), which is known to occur at a certain rate in LC.
