Embolization of spontaneous retroperitoneal bleeding fed by aneurysmal arc of Bühler: Case report and technical considerations.
The arc of Bühler (AOB) is a rare embryonic anastomosis between the celiac artery and the superior mesenteric artery, which may become a crucial collateral pathway in cases of celiac axis stenosis. We report a challenging case of a 70-year-old woman presenting with hemorrhagic shock owing to a…
Open repair and subsequent stenting to treat median arcuate ligament syndrome secondary to Roux-en-Y gastric bypass.
Median arcuate ligament syndrome (MALS) is characterized by external compression of the celiac artery (CA) by the median arcuate ligament. There have been three reports of MALS following gastric bypass surgery, but this pathophysiology remains incompletely understood. We report a patient with MALS a…
A novel case report of hepatic artery bypass following pancreaticoduodenectomy in the setting of median arcuate ligament-associated celiac artery stenosis.
Median arcuate ligament-associated celiac artery stenosis (CAS) is a vascular occlusive condition that is asymptomatic in most individuals. However, it can result in hepatic ischemia in patients undergoing pancreaticoduodenectomy (PD), necessitating advanced surgical intervention. Here, we present t…
Survey of tick species and tick-borne pathogens in pet dogs and cats in mainland China.
Ticks are major vectors of zoonotic diseases, harboring and transmitting various bacteria, viruses and parasites. In mainland China, the rapidly growing population of companion animals has rendered pets important tick hosts and a critical bridge for tick-borne pathogens to infiltrate domestic enviro…
A novel molluscan CNS organ culture for the examination of adult nerve regeneration.
Central nervous system (CNS) regeneration is crucial for re-establishing neural connections following injury. Though some adult vertebrates have regeneration-competent CNS, invertebrate CNS also provide useful model systems for examining cellular and molecular mechanisms promoting regeneration. Usin…
How to Deal with Median Arcuate Ligament during Pancreaticoduodenectomy? Management Strategies and Impact on Perioperative Outcomes.
Median arcuate ligament (MAL) can cause coeliac trunk (CT) stenosis, which is often asymptomatic but may lead to severe hepatic, splenic, or digestive ischemia following pancreaticoduodenectomy (PD). Optimal diagnosis and management remain debated. The purpose of this study was to evaluate managemen…
Surgical Management of Pediatric Superior Mesenteric Artery Syndrome: A Single Institution Continued Experience.
Superior mesenteric artery syndrome (SMAS) is an uncommon cause of abdominal pain, emesis, and weight loss in children. While there are many surgical options, we previously reported a small series of laparoscopic duodenal lowering (DL), which became our standard first approach. Here, we report our e…
Can Duodenal Derotation With Duodenoduodenostomy Be Performed Safely Robotically, and Is It the Optimal Surgical Intervention for SMAS?
BackgroundSuperior mesenteric artery syndrome (SMAS) is a rare disorder with 33% mortality. The Cleveland Clinic reported one of the largest series including 18 patients treated with duodenojejunostomy (DDJ), with 33% showing improvement at 3 years. Alvear et al reported 94.7% improvement in 19 pati…
