We report an extremely rare case of spontaneous closure of grade 1 coronary perforation by the snowplow phenomenon during the revascularization of a subtotal occlusion in the left anterior descending coronary artery. Coronary artery perforation is usually a nightmare during coronary intervention in the cardiac catheterization laboratory. While large coronary perforation requires the deployment of a covered stent, small perforations require heparin reversal, prolonged balloon inflation, deployment of small coils, or gel foam closure...

We present a successful case of treating an infected popliteal aneurysm in a 71-year-old man who arrived at the emergency department in a septic state, reporting a three-week history of fever, lethargy, general malaise, and pain and swelling in the right popliteal fossa. Previously diagnosed with a sizable right popliteal aneurysm, the patient had undergone endovascular treatment using a Viabahn (WL Gore & Associates, Flagstaff, USA) endoprosthesis two months earlier. His fever and malaise emerged a week following minor surgery for a toe infection (panaritium) on the right foot, leading to subsequent necrotic lymphangitis on the dorsum of the same foot...

BACKGROUND: Hyperglycemia, characterized by elevated blood glucose levels, is frequently observed in patients with acute coronary syndrome, including ST-elevation myocardial infarction (STEMI). There are conflicting sources regarding the relationship between hyperglycemia and outcomes in STEMI patients. We aimed to compile evidence to assess the association between hyperglycemia and adverse outcomes. METHODS: We conducted a comprehensive search for articles on PubMed and Embase using search strategies which yielded 4,061 articles...

Coronary stents have saved millions of lives in the last three decades by treating atherosclerosis especially, by preventing plaque protrusion and subsequent aneurysms. They attenuate the vascular SMC proliferation and promote reconstruction of the endothelial bed to ensure superior revascularization. With the evolution of modern stent types, nanotechnology has become an integral part of stent technology. Nanocoating and nanosurface fabrication on metallic and polymeric stents have improved their drug loading capacity as well as other mechanical, physico-chemical, and biological properties...

REVIEW
Pardhu Neelam Bharath, Surinder Singh Rana
Endoscopic transmural drainage is usually performed for symptomatic well-encapsulated walled-off necrosis (WON) that usually develops in the delayed phase (> 4 weeks after disease onset) of acute necrotising pancreatitis (ANP). Endoscopic drainage is usually not advocated in the early (< 4 weeks after disease onset) stage of illness because of the risk of complications due to an incompletely formed encapsulating wall and poor demarcation of viable from necrotic tissue. However, emerging data from expert tertiary care centres over the last few years shows that the early endoscopic transluminal drainage approach is effective and safe...

PURPOSE: : Endotension is a rare late complication characterized by an increase in sac size without any type of endoleak following endovascular aortic aneurysm repair (EVAR). Due to its rarity, few studies have demonstrated the mechanism behind and the management of endotension. In this study, we aimed to better understand the treatment and the long-term outcome of endotension in a single-center cohort. MATERIALS AND METHODS: : This study was designed for a retrospective review of the patients diagnosed with endotension between January 2006 and December 2017...

PURPOSE: Self-expandable metallic stent (SEMS) placement is widely used as a bridge to surgery (BTS) procedure for obstructive colorectal cancer. However, evidence regarding the optimal interval between SEMS placement and elective surgery is lacking. METHODS: We retrospectively collected data from patients with BTS between January 2013 and October 2021. Inverse probability treatment-weighted propensity score analyses were used to compare short- and long-term outcomes between the short-interval (SI) and long-interval (LI) groups, using a cutoff of 20 days...

Small animal transplant models are indispensable for organ tolerance studies investigating feasible therapeutic interventions in preclinical studies. Rat liver transplantation (LTx) protocols typically use an orthotopic model where the recipients' native liver is removed and replaced with a donor liver. This technically demanding surgical procedure requires advanced micro-surgical skills and is further complicated by lengthy anhepatic and lower body ischemia times. This prompted the development of a less complicated heterotopic method that can be performed faster with no anhepatic or lower body ischemia time, reducing post-surgery stress for the recipient animal...

A 73-year-old man was admitted with four weeks of intermittent fever. He had a history of total aortic arch replacement for aortic arch aneurysm four years prior. CT scans showed no abnormalities before admission. Repeated blood cultures yielded Streptococcus anginosus and Prevotella melaninogenica, suggesting infective endocarditis (IE). Transesophageal echocardiography revealed a vegetation on the aortic valve, confirming IE. He suddenly presented with massive hematemesis and hypotension. Endoscopy revealed an elevated lesion with a laceration but no active bleeding in the esophagus...

In vitro testing methods offer valuable insights into the corrosion vulnerability of metal implants and enable prompt comparison between devices. However, they fall short in predicting the extent of leaching and the biodistribution of implant byproducts under in vivo conditions. Physiologically based toxicokinetic (PBTK) models are capable of quantitatively establishing such correlations and therefore provide a powerful tool in advancing nonclinical methods to test medical implants and assess patient exposure to implant debris...

Left-sided portal hypertension (LSPH), an uncommon manifestation of portal hypertension, is characterized by conditions such as isolated gastric varices and splenomegaly, which result from impeded splenic venous drainage in the presence of pancreatic disease. We employed a percutaneous transhepatic technique to achieve regression of isolated gastric varices by implanting a covered stent within a blocked splenic vein and by embolizing the posterior gastric vein and varices using N-butyl-2-cyanoacrylate. We report the successful treatment of stenting for LSPH by the covered stent placement...

Retroportal artery is one of the communicating arteries between the hepatic artery and the superior mesenteric artery, but it is often a small artery and usually unrecognized. We report a 60-year-old man that was successfully treated for postpancreatectomy hemorrhage from the retroportal artery with compression of the celiac trunk by the median arcuate ligament. Following the pancreaticoduodenectomy, the bloody discharge was discovered through the drainage catheter. We underwent transcatheter arterial embolization for the bleeding from the retroportal artery associated with a postoperative pancreatic fistula...
