A 69-year-old man with portal hypertension was admitted with decompensated alcoholic cirrhosis and diuretic resistant ascites. Ultrasound revealed partial portal thrombosis. Due to diuretic intolerance, transjugular intrahepatic portosystemic shunt (TIPS) was decided during which a hepatic arterial branch was inadvertently catheterized. Finally, TIPS was created, but the patient continued gaining weight. Color-Doppler ultrasonography (CDUS) showed upper stent part patency with absence of flow in lower stent portion. Twenty-five days later, the patient presented melena. Endoscopy revealed blood emerging from the Vater papilla. Hepatic angiography revealed arteriovenous shunt between a hepatic arterial branch and the proximal part of the TIPS shunt. Covered stent placement restored sufficient TIPS flow. The patient deteriorated and died 1 month later. We found out that our major technical drawback was that we did not inject a small amount of contrast after puncturing the supposed portal vein, in order to confirm correct position of the needle.

Introduction: Patients with end-stage renal disease usually undergo hemodialysis as a way of renal function replacement therapy which comes with a wide array of systemic and cutaneous complications. The aim of this study was to evaluate the most frequent dermatological manifestations including xerosis, pruritis and other nail, hair and oral conditions, as these are a very important aspect to be considered while managing the patients psychological and physical needs to improve their outcomes and quality of life.
Methods: This retrospective cross-sectional study was performed by selecting 77 patients on hemodialysis based on a certain criteria and data was then collected on a sheet using patients database on Hakeem National E-Health Program, in addition to information from interviews with patients during their hemodialysis sessions after taking an oral informed consent and insuring patients' privacy.

Introduction: The 2019 Kidney Disease Outcome Quality Initiative guidelines emphasize the importance of selecting dialysis based on the life expectancy of the patient. However, it is difficult to predict the life expectancy of a patient during arteriovenous fistula creation. We investigated whether neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios measured before dialysis could predict mortality.

Hemodialysis for chronic kidney disease (CKD) relies on vascular access (VA) devices, such as arteriovenous fistulas (AVF), grafts (AVG), or catheters, to maintain blood flow. Nonetheless, unpredictable progressive vascular stenosis due to neointimal formation or complete occlusion from acute thrombosis remains the primary cause of mature VA failure. Despite emergent surgical intervention efforts, the lack of a reliable early detection tool significantly reduces patient outcomes and survival rates.

Autogenous arteriovenous fistula (AVF) is the vascular access of choice for chronic kidney disease to patients requiring hemodialysis. However, there still needs to be more consensus on whether the best surgical approach is an end-of-vein to side-of-artery (ETS) or a side-of-vein to side-of-artery (STS) anastomosis. This study aims to compare venous maturation rates, mid-term patency and post-operative steal syndrome rates between ETS and STS techniques for arteriovenous fistulas.

Objective: This study aims to evaluate the short-term efficacy of right-to-left shunt closure in vestibular migraine patients, and compare the efficacy between patent foramen ovale (PFO) closure and pulmonary arteriovenous malformation (PAVM) embolization. Additionally, the study identifies factors related to surgical outcomes.
Methods: Forty-one patients with vestibular migraine and medium to large right-to-left shunts underwent surgery: PFO closure, PAVM embolization, or both.
