Preemptive VAE-An Important Tool for Managing Blood Loss in MVT Candidates With PMT.

Transplant Direct 2021 Mar 11;7(3):e670. Epub 2021 Feb 11.

Department of Surgery, Duke University Hospital, Durham, NC.

Explantation of native viscera in multivisceral transplant candidates, particularly in those with extensive portomesenteric thrombosis (PMT), carries considerable morbidity due to extensive vascularized adhesions. Preemptive visceral angioembolization has been previously described as a technique to minimize excessive blood loss during mobilization of the native viscera but is not well described specifically in patients with extensive PMT.

Methods: In a series of 5 patients who underwent mutivisceral transplant for PMT from June 2015 to November 2018, we performed preoperative superior mesenteric, splenic, and hepatic artery embolization to reduce blood loss during explanation and evaluated the blood loss and blood product utilization, as well as 30-day rates of infectious complications.

Right paraduodenal hernia accompanying superior mesenteric vein thrombosis: a rare case.

BMJ Case Rep 2021 Jun 4;14(6). Epub 2021 Jun 4.

General Surgery Department, Koç University Hospital, Istanbul, Turkey.

A 59-year-old man with abdominal pain was admitted to the emergency department. Investigations had revealed a right-sided paraduodenal hernia and superior mesenteric vein (SMV) twisting around the superior mesenteric artery in rotation, the 'whirlpool sign'. Owing to the increasing severity of abdominal pain and the presence of SMV thrombosis complicated with strangulated paraduodenal herniation associated with high mortality rates, diagnostic laparoscopy was performed.

Occlusion of the Superior Mesenteric Artery in Rats Reversed by Collateral Pathways Activation: Gastric Pentadecapeptide BPC 157 Therapy Counteracts Multiple Organ Dysfunction Syndrome; Intracranial, Portal, and Caval Hypertension; and Aortal Hypotension.

Biomedicines 2021 May 26;9(6). Epub 2021 May 26.

Department of Pharmacology, School of Medicine, University of Zagreb, 10000 Zagreb, Croatia.

Gastric pentadecapeptide BPC 157 therapy counteracts multiple organ dysfunction syndrome in rats, which have permanent occlusion of the superior mesenteric artery close to the abdominal aorta. Previously, when confronted with major vessel occlusion, its effect would rapidly activate collateral vessel pathways and resolve major venous occlusion syndromes (Pringle maneuver ischemia, reperfusion, Budd-Chiari syndrome) in rats. This would overwhelm superior mesenteric artery permanent occlusion, and result in local, peripheral, and central disturbances. Read More

Targeting the Rat's Small Bowel: Long-Term Infusion into the Superior Mesenteric Artery.

J Vis Exp 2021 04 8(170). Epub 2021 Apr 8.

Department of Emergency Surgery, Università Cattolica del S. Cuore.

The superior mesenteric artery can be cannulated in humans through minimally invasive radiological catheterization of the femoral or axillary artery. SMA cannulation is more difficult in rats due to small anatomical dimensions. The aim of the study is to describe a surgical technique for cannulation of the SMA in rats to perform long-term infusion of drugs into the SMA vascular bed in unrestricted animals, which will result in a high rate of catheter patency after the post surgical recovery for 24 hours.

Predictors and risk factors for intestinal necrosis in patients with mesenteric ischemia.

Ann Transl Med 2021 Feb;9(4):337

Department of Gastrointestinal Surgery, Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University, Beijing, China.

Background: Mesenteric ischemia results in blood flow that is insufficient to meet metabolic demands and subsequent dysfunction of visceral organs, including arterial obstruction and venous thrombosis. Sustained mesenteric ischemia exhausts the ability of capillaries to provide oxygen and initiate an inflammatory reaction, and eventually leads to intestinal mucosal necrosis, a serious and potentially life-threatening condition. Therefore, it is essential that the predictors and risk factors for intestinal necrosis in patients with mesenteric thrombus are explored. Read More

Two-way Revascularization to Manage Celiac Artery Stenosis during Pancreaticoduodenectomy: A Case Report.

Plast Reconstr Surg Glob Open 2021 Feb 15;9(2):e3423. Epub 2021 Feb 15.

Department of Dermatology, Yamaguchi University Graduate School of medicine, Ube, Japan.

Celiac artery (CA) occlusion, or stenosis, is not uncommon, and most cases are asymptomatic. If the CA is occluded, collateral circulation from the superior mesenteric artery (SMA) is maintained through the pancreaticoduodenal arcade. However, the pancreaticoduodenal arcade is removed if pancreaticoduodenectomy (PD) is performed, which results in ischemia of the liver, stomach, and residual pancreas. Read More

Splenoportal-mesenteric axis thrombosis and splenic artery occlusion as initial presentations of COVID-19 disease.

Eur Rev Med Pharmacol Sci 2021 Feb;25(3):1680-1683

Interventional Radiology Unit, Department of Biomedicine and Prevention, University Hospital Policlinico Tor Vergata, Rome Italy.

Objective: Although pulmonary involvement represents the primary and most characteristic presentation of Sars-Cov-2 infection, due to its innate tropism for endothelium, it is also associated with systemic pro-coagulative changes and thromboses. This paper describes a COVID-19 atypical presentation with massive thrombotic occlusion of the splenoportal-mesenteric axis and the splenic artery in the absence of clinical or radiological manifestation of pulmonary involvement.

Patients And Methods: Female patient, with no history of disease, trauma or fever in the last 30 days, was admitted to ER for persistent left subcostal pain. Read More

Back-table surgery pancreas allograft for transplantation: Implications in complications.

World J Transplant 2021 Jan;11(1):1-6

Department of General and Digestive Surgery, Reina Sofia University Hospital, Cordoba 14004, Spain.

To describe the main aspects of back-table surgery in pancreatic graft and the problems arising from poor technique. Back-table surgery for pancreatic graft is a complex, meticulous and laborious technique on which the success of implant surgery and perioperative results depends. The technique can be described in the following steps: Preparation of the sterile table, inspection of the pancreas-spleen block, management of the duodenum, identification of the bile duct, preparation of the portal vein, preparation of the own graft arteries and anastomosis to the arterial graft, spleen management and graft preservation prior to implantation in the recipient.

Proximal Aortic Coverage and Clinical Results of the Endovascular Repair of Juxta-/Para-renal and Type IV Thoracoabdominal Aneurysm with Custom-made Fenestrated Endografts.

Ann Vasc Surg 2021 May 4;73:397-406. Epub 2021 Jan 4.

Vascular Surgery, Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, Bologna, Italy.

Background: Juxta-renal (JAAA)/para-renal (PAAA) and type IV-thoracoabdominal (TAAA) aneurysms can be repaired by custom-made fenestrated endografts (CM-FEVAR). Differently from open repair, a relatively long segment of healthy proximal aorta needs to be covered to achieve a durable sealing, and this may be considered a disadvantage of the endovascular approach. We aimed to quantify the additional proximal aortic coverage in JAAAs, PAAAs, and type-IV TAAAs treated with CM-FEVAR and to evaluate its impact on early/follow-up clinical outcomes. Read More
