Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by acute severe headache with or without additional neurological symptoms and reversible vasoconstriction. Unruptured aneurysms have been reported in some cases RCVS. We describe a case of 50-year-old woman RCVS presenting as cortical subarachnoid hemorrhage. Cerebral angiogram demonstrated the typical angiographic findings two very small unruptured left internal carotid artery. The patient was treated calcium channel...

The use of platelet-rich plasma (PRP) for the treatment nonhealing ulcers is a relatively new technique. Although it seems to result in satisfying level healing and low complication rates, data regarding its effectiveness remain sparse. This study aims evaluate potential therapeutic effects PRP on chronic ulcers.This was prospectively designed comparing outcomes between patients treated with (Group A, n=15) conventionally B, n=12) different types ulcers. In Group produced from patients' own...

Cavernous malformations (CM) of the central nervous system constitute rare vascular lesions. They are usually asymptomatic, which has allowed their management to become quite debatable. Even when they symptomatic optimal mode and timing treatment remains controversial.A consensus may navigate neurosurgeons through decision-making process selecting for asymptomatic CMs.A 17-item questionnaire was developed address controversial issues in relation aspects treatment, surgical planning, strategy...

Preoperative risk stratification in the elderly surgical patient is an essential part of contemporary perioperative care and can be done with use American College Surgeons Surgical Risk Calculator (ACS-SRC). However, data on generalizability ACS-SRC scarce. In this study, we report external validation ACS-RC a geriatric cohort. A retrospective analysis prospectively maintained database was performed including patients aged > 65 who underwent general surgery procedures during 2012–2017...

Abstract Aim This study aims to assess the outcomes of Laparoscopic Common Bile Duct Exploration (LCBDE) as a single-stage procedure for symptomatic choledocholithiasis. Methods In this retrospective analysis we included 87 patients with high suspicion common bile duct (CBD) stones, imaging proven choledocholithiasis or failed Endoscopic Retrograde cholangiopancreatography (ERCP). These underwent either LCBDE CBD exploration under fluoroscopy between 2019 and 2023. Results Among selected...

Hintergrund: Die einzige Chance auf Heilung bei Patienten mit Pankreaskarzinom besteht in der kompletten Turmorresektion. Trotz verbesserter bildgebender Verfahren ist die definitive Beurteilung Resektabilität erst intraoperativ nach sorgfältiger Exploration möglich. und Methoden: Wir berichten über 17 einem Pankreasmalignom, aufgrund einer auswärtigen Laparotomie als inoperabel eingestuft wurden eine Second-Look-Operation unserer Klinik erhielten. Ergebnisse: Im Rahmen erwies sich das...

Emerging mission-critical and functional safety applications require high-performance processors that meet strict reliability requirements against random hardware failures. These touch even sub-systems within the core that, so far, may have been considered as low-significance contributors to processor failure rate. This paper identifies register renaming sub-system of an out-of-order a prime example where cost-efficient non-intrusive protection can enable future their goals. We propose two...

Cerebral Arteriovenous Malformations (AVM) are complex vascular formations, variable in size and angioarchitecture they may locate at any part of the brain. They present with epilepsy or focal neurological signs occasionally discovered incidentally. also rupture, creating intracranial hemorrhage associated considerable morbidity mortality. As a consequence these lesions should be, most time, be treated. There three treatment options: surgery, embolization radiosurgery. What modality is best...
