Advancing remote sensing and machine learning-driven frameworks for groundwater withdrawal estimation in Arizona: Linking land subsidence to groundwater withdrawals.

Groundwater plays a crucial role in sustaining global food security but is being over-exploited in many basins of the world. Despite its importance and finite availability, local-scale monitoring of groundwater withdrawals required for sustainable water management practices is not carried out in most countries, including the United States. In this study, we combine publicly available datasets into a machine learning framework for estimating groundwater withdrawals over the state of Arizona.

Management of Aortic Pseudoaneurysms: Evolving Concepts and Controversies.

Background:  Techniques to repair aortic pseudoaneurysms have been rapidly evolving. We present our results following open and endovascular repair of aortic pseudoaneurysms from 2009 to 2013.

Methods:  A total of nine patients underwent pseudoaneurysm repair from April 2009 to February 2013.

Role of Moderate Hypothermia and Antegrade Cerebral Perfusion during Repair of Type A Aortic Dissection.

The goal of this study was to compare early postoperative outcomes and actuarial survival between patients who underwent repair of acute type A aortic dissection with deep or moderate hypothermia. A total of 132 consecutive patients from a single academic medical center underwent repair of acute type A aortic dissection between January 2000 and June 2014. Of those, 105 patients were repaired under deep hypothermia (< 24 C°), while 27 patients were repaired under moderate hypothermia (≥24 C°).

Bovine arch anatomy influences recoarctation rates in the era of the extended end-to-end anastomosis.

Objectives: Arch branching has never been shown to influence recoarctation after extended end-to-end anastomosis via thoracotomy, yet in each study bovine arch identification is grossly underreported. This study aims to (1) assess chart review reliability in bovine arch identification; (2) determine recoarctation risk with a bovine arch; and (3) explore an anatomic explanation for recurrent arch obstruction based on arch anatomy.

Patients: A total of 49 consecutive patients underwent thoracotomy with extended end-to-end aortic coarctation repair at a single institution (2007-2012).

Effects of Gender on Outcomes and Survival Following Repair of Acute Type A Aortic Dissection.

Previous studies have demonstrated gender-related differences in early and late outcomes following type A dissection diagnosis. However, it is widely unknown whether gender affects early clinical outcomes and survival after repair of type A aortic dissection. The goal of this study was to compare the early and late clinical outcomes in women versus men after repair of acute type A aortic dissections.

A minimally invasive, algorithm-based approach for anomalous aortic origin of a coronary artery.

Objective: Operative repair for anomalous aortic origin of a coronary artery (AAOCA) has been described using various innovative techniques. Common to each series is the use of a full sternotomy. As demand for minimally invasive approaches to adult cardiac surgery has increased, the upper hemisternotomy has emerged as a safe and effective technique for aortic valve and root replacement.

Improved clinical outcomes and survival following repair of acute type A aortic dissection in the current era.

Objectives: The goal of this study was to compare early postoperative outcomes and actuarial-free survival between patients who underwent repair of acute type A aortic dissection during 2000-2005 and 2006-2010.

Methods: A total of 251 patients from four academic medical centres underwent repair of acute type A aortic dissection between January 2000 and October 2010. Of those, 111 patients underwent repair during 2000-2005, whereas 140 patients underwent repair during 2006-2010.

Effects of Hemodynamic Instability on Early Outcomes and Late Survival Following Repair of Acute Type A Aortic Dissection.

Background: The goal of this study was to compare operative mortality and actuarial survival between patients presenting with and without hemodynamic instability who underwent repair of acute Type A aortic dissection. Previous studies have demonstrated that hemodynamic instability is related to differences in early and late outcomes following acute Type A dissection occurrence. However, it is unknown whether hemodynamic instability at the initial presentation affects early clinical outcomes and survival after repair of Type A aortic dissection.

Renal artery implantation angles in thoracoabdominal aneurysms and their implications in the era of branched endografts.

Purpose: To determine the renal artery to aorta relationship in the setting of thoracoabdominal aortic aneurysm (TAAA) in order to help strategize preoperative stent-graft planning, device design, and deployment technicalities.

Methods: The preoperative computed tomography (CT) studies of 147 patients who underwent TAAA repair between 2005 and 2008 were retrospectively reviewed. The Crawford classification of the TAAA, the renal artery implantation angle (RAIA), and the maximal aortic diameter were determined using 3-dimensional imaging analysis (centerline of flow).
