Hybrid Management of Acute Portal Vein Thrombosis Complicated by Mesenteric Ischemia

Treatment for portal vein thrombosis complicated by mesenteric ischemia can be treated in the operating room following a hybrid approach. This allows for efficient care of the patient, avoids the need for transhepatic cannulation for obtaining a venogram and placing a thrombolysis catheter, and obviates the need to obtain percutaneous venous access.

Challenges of elderly patients with short bowel syndrome

Objective: This is a case report presenting two elderly patients; one with mesenteric ischemia and the second with gallstone ileus, in which their operative management has resulted in short bowel syndrome (SBS). Case: This pathology required prolonged post-operative care and monitoring with the management of different related complications. Conclusion: This case report will cover the pathophysiology, medical and operative management in addition to the acute and chronic complications of SBS

Acute Mesenteric Ischemia in COVID-19 Patients

Acute mesenteric ischemia is a rare but extremely severe complication of SARS-CoV-2 infection. The present review aims to document the clinical, laboratory, and imaging findings, management, and outcomes of acute intestinal ischemia in COVID-19 patients. A comprehensive search was performed on PubMed and Web of Science with the terms “COVID-19” and “bowel ischemia” OR “intestinal ischemia” OR “mesenteric ischemia” OR “mesenteric thrombosis”. After duplication removal, a total of 36 articles were included, reporting data on a total of 89 patients, 63 being hospitalized at the moment of onset. Elevated D-dimers, leukocytosis, and C reactive protein (CRP) were present in most reported cases, and a contrast-enhanced CT exam confirms the vascular thromboembolism and offers important information about the bowel viability. There are distinct features of bowel ischemia in non-hospitalized vs. hospitalized COVID-19 patients, suggesting different pathological pathways. In ICU patients, the most frequently affected was the large bowel alone (56%) or in association with the small bowel (24%), with microvascular thrombosis. Surgery was necessary in 95.4% of cases. In the non-hospitalized group, the small bowel was involved in 80%, with splanchnic veins or arteries thromboembolism, and a favorable response to conservative anticoagulant therapy was reported in 38.4%. Mortality was 54.4% in the hospitalized group and 21.7% in the non-hospitalized group (p < 0.0001). Age over 60 years (p = 0.043) and the need for surgery (p = 0.019) were associated with the worst outcome. Understanding the mechanisms involved and risk factors may help adjust the thromboprophylaxis and fluid management in COVID-19 patients.

Retrograde Superior Mesenteric Artery Stenting in Case of SMA Shuttering

This case describes a patient who underwent endovascular repair for an extent V thoracoabdominal aneurysm with planned coverage of the celiac artery. Following deployment of the stent graft, the superior mesenteric artery was shuttered, and the patient subsequently developed signs and symptoms of bowel ischemia. The patient underwent successful retrograde open superior mesenteric artery stenting with resolution of her symptoms. Although retrograde open mesenteric artery stenting (ROMS) has been primarily shown to be effective in acute mesenteric ischemia, this case demonstrates that ROMS can be used as a salvage option for shuttering during endovascular procedures.

Ethical Dilemma: Is it Worthwhile Operating an End-Stage Pancreatic Cancer Patient with Acute Mesenteric Artery Ischemia?

Pancreatic cancer is as an aggressive malignancy with low survival rates. We present the first case of an operation of acute mesenteric ischemia performed in a patient with end-stage pancreatic adenocarcinoma. Through this case, we also discuss raising concerns regarding the management of severe complications such as acute mesenteric ischemia in patients with progressed pancreatic carcinoma. How ethical is to leave patients untreated? The decisions for management of patients with advanced disease are strongly based on the expected quality of life, ethical principles, different religions and spiritualities, and the burden of healthcare cost.
