The use of the retrograde approach to treat chronic total occlusion (CTO) has improved overall success rate in this lesion subgroup. Its use to treat complex non-CTO lesions unable to be revascularized by an antegrade approach has not been described. We report a case of the use of the retrograde approach to recanalize a non-CTO lesion under Impella support in a patient with critical stenosis and poor left ventricular function. The retrograde approach may be an alternate pathway in selected non-CTO lesions where the antegrade has been unsuccessful.

A Novel Technique of "Drag-Drill" for Retrograde Chronic Total Occlusion Revascularization in Heavily Calcified Tortuous Lesions: A Case Report.

We report the case of a 73-year-old male with a history of recurrent coronary interventions who presented with progressive angina and was diagnosed with a chronic total occlusion (CTO) of a heavily calcified and tortuous right coronary artery (RCA). Standard antegrade and retrograde techniques were attempted but failed due to the complexity of the lesion. A novel "Drag-Drill" technique was employed, utilizing a retrogradely externalized RG3 guidewire as a rotational atherectomy wire, enabling successful rotational atherectomy and percutaneous coronary intervention (PCI).

Traditional approaches have often focused on individual brain regions and connections that do not capture the topographic organization of forebrain connectivity. We performed co-injections of anterograde and retrograde tract tracers in rats to provide novel high-spatial resolution evidence of topographic connections that elaborate a previously identified closed-loop forebrain circuit implicated in affective and motivational processes.

A supernumerary kidney is a rare birth defect where an extra kidney is present. This extra kidney has its own separate outer covering, blood supply, and collection system. Normally, percutaneous nephrolithotomy (PCNL) is the treatment of choice for large kidney stones, but its ideal use for supernumerary kidneys is unknown.

Lemmel syndrome involves a periampullary duodenal diverticulum (PAD), a pouch-like outpouching near the ampulla of Vater, compressing the common bile duct. We describe a case of severe abdominal pain in a patient who had a large periampullary diverticulum, managed with surgical intervention after an initial failed endoscopic retrograde cholangiopancreatography (ERCP). An elderly female patient in her early 90s arrived at the emergency department with severe cramping pain localized to the right upper quadrant of her abdomen, progressively intensifying over several weeks.

Purpose Of Review: Neuroendocrine tumours (NET) are rare entities arising from hormone producing cells in the gastroentero-pancreatic (GEP) tract. Surgery is the most common treatment of GEP-NETs.
Recent Findings: Improvements in surgical techniques allow for more locally advanced and metastasised GEP-NETs to be resected.
