Transient alteration of consciousness in spinal cord injury secondary to Baclofen use: a case report.

Spinal Cord Ser Cases 2022 May 21;8(1):56. Epub 2022 May 21.

Department of Spinal Cord Injury, Veterans Affairs New Jersey Health Care System, East Orange, NJ, 07018, USA.

Introduction: Oral baclofen is commonly used for spasticity management, especially with neurogenic bladder in spinal cord injury (SCI). A less common side effect of baclofen is transient alterations of consciousness, which can easily be confused for altered mental status secondary to orthostatic hypotension in SCI.

Case Presentation: A 43-year-old man with an acute SCI secondary to an aortic dissection was found to have episodes of confusion after titrating oral baclofen from 5 mg three times per day to 10 mg three times per day at an acute rehabilitation facility. Read More

Can We Better Differentiate Type A Dissections: Evaluating the Role of Aortic Ratios.

Heart Lung Circ 2022 May 18. Epub 2022 May 18.

Department of Cardiothoracic Surgery, Waikato District Health Board, Hamilton, New Zealand; Waikato Institute of Surgical Education and Research (WISER), Hamilton, New Zealand; Department of Surgery, University of Auckland, Hamilton, New Zealand.

Objectives: Type A aortic dissection (ATAAD) is hypothesised as a progression of aneurysmal dilation, but 60% of patients in the International Registry of Acute Aortic Dissection (iRAD) registry had a maximum aortic diameter (MAD)<55 mm. We aim to demonstrate that size ratios and aortic wall stress, assessed using a simplified markers, are unique to aortic patients who have had adverse events (ATAAD) compared to those who have not (thoracic aortic aneurysm [TAA]).

Methods: A retrospective cohort analysis of patients who underwent aortic intervention at Waikato Hospital, New Zealand between 2015-2020, comparing dissection (ATAAD) to TAA patients. Read More

Endovascular Repair in Patients with Marfan Syndrome: Concerns Amid Controversy.

Ann Vasc Surg 2022 May 17. Epub 2022 May 17.

Division of Cardiothoracic Surgery, Michael E. DeBakey Department of Surgery, Baylor College of Medicine, Houston, Texas, USA; Department of Cardiovascular Surgery, Texas Heart Institute, Houston, Texas, USA; Department of Cardiovascular Surgery, CHI St Luke's Health-Baylor St Luke's Medical Center, Houston, Texas, USA; Cardiovascular Research Institute, Baylor College of Medicine, Houston, Texas, USA. Electronic address:

Endovascular aortic repair is widely used to treat patients with degenerative aneurysms or aortic dissection within the distal aorta. Thoracic endovascular aortic repair (TEVAR) is generally associated with fewer short-term complications than open surgical repair, which is particularly important for older patients with significant comorbid conditions. However, for patients with Marfan syndrome, a heritable thoracic aortic disease associated with aortic dilatation, dissection, and rupture, the utility of endovascular aortic repair remains questionable.

Front Cardiovasc Med 2022 3;9:840946. Epub 2022 May 3.

Department of Cardiovascular Surgery, First Affiliated Hospital of Anhui Medical University, Hefei, China.

It has been found that postoperative progressive dilatation of aortic root is not rare for adult patients with repaired Tetralogy of Fallot (TOF), which leads to severe aortic regurgitation or even fatal dissection. Therefore, clinically, surgical treatment for both regurgitated aortic valve and dilated root is needed based on preoperative assessments and individual treatment strategies. Read More

Identification of a novel pathogenic variant in FBN1 associated with Marfan Syndrome.

Cold Spring Harb Mol Case Stud 2022 May 19. Epub 2022 May 19.

Universidade Estadual do Norte Fluminense Darcy Ribeiro

Aortic diseases arising in Marfan Syndrome (MFS), such as in aneurysms and dissections of the thoracic aorta, are related to genetic alterations in the FBN1 gene. Databases, such as Universal Mutations-FBN1, ClinVar and The Human Gene Mutation, contain more than a thousand FBN1 mutations associated with MFS. The FBN1 gene, which encodes fibrillin-1, is responsible for the integral production of different protein domains. Read More

Semin Thorac Cardiovasc Surg 2022 May 16. Epub 2022 May 16.

Department of Cardiac Surgery, Michigan Medicine, Ann Arbor, Michigan. Electronic address:

With increasing specialization within the field of cardiac surgery and a positive relationship between case volume and surgical outcomes in many areas, the concept of dedicated aortic surgeons performing acute type A aortic dissection (ATAAD) repair was investigated. From 1996 to 2014, 436 patients underwent open surgical repair of an ATAAD and were subsequently divided based on surgeon subspecialization, aortic-surgeon (AS, n=401) vs. non-aortic-surgeon (NAS, n=35).

Case report of Modified Viabahn Open Revascularization TEChnique (VORTEC) as a rescue strategy for hepatic artery dissection after initial endovascular treatment of postpancreaticoduodenectomy hemorrhage.

Medicine (Baltimore) 2022 May 13;101(19):e29176. Epub 2022 May 13.

Department of General Surgery, Kaohsiung Chang Gung Memorial Hospital, Kaohsiung, Taiwan.
