Shock Management Without Formal Fluid Responsiveness Assessment: A Retrospective Analysis of Fluid Responsiveness and Its Outcomes.

Background: In order to quantify fluid administration and evaluate the clinical consequences of conservative fluid management without hemodynamic monitoring in undifferentiated shock, we analyzed previously collected data from a study of carotid Doppler monitoring as a predictor of fluid responsiveness (FR).

Methods: This study was a retrospective analysis of data collected from a single tertiary academic center from a previous study. Seventy-four patients were included for post-hoc analysis, and 52 of them were identified as fluid responsive (cardiac output increase > 10% with passive leg raise) according to NICOMTM bioreactance monitoring (Cheetah Medical, Newton Center, MA, USA).

Primary cardiac angiosarcoma masquerading as intracardiac thrombus.

A 49-year-old man with a recent history of atrial tachycardia and intracardiac thrombus presented to the emergency department with melena and cardiac tamponade. Physical examination was notable for a vascular mass at the right lower gingival sulcus and a right chest wall nodule. Enteroscopy revealed a target lesion with friable ulcer in the gastric body.

Takayasu Arteritis With Extensive Cardiovascular, Neurovascular, and Mesenteric Involvement.

Takayasu arteritis is a rare large vessel vasculitis with an incidence of 1 to 3 per million. This disease typically involves the aorta and its primary branches but has been found to involve the coronary arteries in 7% to 9% of cases. We highlight the need for prompt diagnosis and treatment.

Distal Left Main Coronary Artery Aneurysm Resection during 5-Vessel Coronary Artery Bypass Grafting.

Coronary artery aneurysms are abnormal dilations of arterial segments, in some cases associated with underlying atherosclerosis. Although affected patients can be asymptomatic, some are at risk of plaque rupture, dissection, and other complications. Investigations into the optimal management of these vascular malformations are ongoing, because no consensus exists regarding when and how best to intervene.

Gastrointestinal Manifestations of Hereditary Hemorrhagic Telangiectasia (HHT): A Systematic Review of the Literature.

Hereditary hemorrhagic telangiectasia (HHT), also called Osler-Weber-Rendu syndrome, is an autosomal dominant genetic disease that affects the vasculature of numerous organs. The prevalence of HHT is estimated to be between 1.5 and 2 persons per 10,000.
