Successful Coil Embolization with Sclerotherapy for Bleeding Stomal Varices Using a Direct Percutaneous Approach: A Case Report.

Patients with portal hypertension who have undergone stoma surgery are at risk of developing stomal varices, which can occasionally lead to bleeding. Recurrent stomal bleeding can be life-threatening; however, the optimal treatment for this condition remains unestablished due to the rarity of such varices. We report a case of a 73-year-old man with liver cirrhosis and a history of abdominoperineal resection with colostomy for rectal cancer, in whom stomal variceal bleeding was successfully treated with coil embolization and sclerotherapy via a direct percutaneous approach to the afferent vein.

Neurologic symptoms as a hallmark of glymphatic alteration in recovered patients with COVID-19.

Background: The glymphatic system is a glial-based perivascular network that facilitates the clearance of metabolic waste from the brain. Dysfunction of the glymphatic system, along with neurological symptoms such as cognitive deficits and olfactory dysfunction, has been reported in patients with coronavirus disease (COVID-19). However, the link between these neurological symptoms and alterations in the glymphatic system remains unclear.

Effectiveness of Continuous Intra-Arterial Nimodipine Infusion for the Treatment of Refractory Vasospasm after Aneurysmal Subarachnoid Hemorrhage.

Objective: Delayed cerebral ischemia (DCI) is a severe complication following aneurysmal subarachnoid hemorrhage (aSAH), potentially leading to functional impairments. Cerebral vasospasm (CVS) is one of the primary mechanisms of DCI. In cases of medically refractory CVS, intra-arterial (IA) nimodipine is a rescue treatment, but its effectiveness can be insufficient.

Given that the disability in patients with MS may depend on the underlying structural connectivity of the brain, our study aimed to examine the association between white matter tracts affected by MS and the patients' disability using a new tract density index (TDI).

Method: This study included 53 patients diagnosed with MS, examined between 2019 and 2020.

Anatomical Variations Encountered during Adrenal Venous Sampling: A Report of Three Case Series and Review of Literature.

Primary aldosteronism is a group of disorders in which the autonomous secretion of aldosterone is associated with hypertension and hypokalemia. It is crucial to determine the laterality of aldosterone hypersecretion because treatment options differ accordingly. Adrenal venous sampling (AVS) is considered the most reliable method for assessing the laterality of primary aldosteronism.

[Adrenal Vein Sampling in Primary Aldosteronism: A Pictorial Essay for Optimal Left-Side Sampling].

Primary aldosteronism (PA) is a curable cause of hypertension. Recent studies have revealed that the actual prevalence of PA is higher than previously recognized. Adrenal vein sampling (AVS) is an essential diagnostic procedure for revealing the cause of PA and determining the treatment plan.
