Surgical bypass of superior and inferior mesenteric arteries with Dacron graft in a patient with acute on chronic mesenteric ischaemia with atherosclerotic complete occlusion of the infrarenal aorta.

A 67-year-old male presented to us with symptoms of postprandial abdominal pain for the last 3 months and was not able to take meals for the last month. The computed tomography (CT) angiogram showed complete occlusion in the coeliac artery (CA), superior mesenteric artery (SMA) and inferior mesenteric artery (IMA) with complete occlusion of infrarenal aorta and bilateral iliac arteries. While waiting for elective surgical mesenteric bypass, patient suddenly developed signs of peritonitis for which emergency surgery was done using a Dacron bifurcated graft 12 × 6 mm size.

Use of roller pump in venovenous extracorporeal membrane oxygenation as an emergency rescue procedure.

A 41 years old male patient, having acute respiratory distress syndrome (ARDS) due to viral pneumonia, was put on venovenous (VV) extracorporeal membrane oxygenation (ECMO). After 3 h of initiation, the ECMO pump malfunctioned. The patient was initially managed on a hand crank for 5 h.

Decoloniality and anti-oppressive practices for a more ethical ecology.

Ecological research and practice are crucial to understanding and guiding more positive relationships between people and ecosystems. However, ecology as a discipline and the diversity of those who call themselves ecologists have also been shaped and held back by often exclusionary Western approaches to knowing and doing ecology. To overcome these historical constraints and to make ecology inclusive of the diverse peoples inhabiting Earth's varied ecosystems, ecologists must expand their knowledge, both in theory and practice, to incorporate varied perspectives, approaches and interpretations from, with and within the natural environment and across global systems.

Physiological Lung Exclusion in Tetralogy of Fallot Without Left Pulmonary Artery With Aspergilloma.

Tetralogy of Fallot with unilateral absence of the pulmonary artery is a rare congenital cardiac disorder that makes the ipsilateral lung susceptible to opportunistic infections. This disorder adds to the complexity of the case and tests the surgical and decision-making skills of the surgeon. We present an adult male patient with tetralogy of Fallot and absent left pulmonary artery who underwent physiologic exclusion of the left lung for aspergilloma along with intracardiac repair as a single stage procedure.
