Myeloproliferative neoplasms (MPNs) present a unique challenge in surgical management due to their inherent predisposition to both bleeding and thrombosis. MPNs are a heterogenous group of acquired clonal conditions. The three classic MPNs are essential thrombocythemia (ET), myelofibrosis (PMF), and polycythemia vera (PV). All subtypes of MPN are associated with both thrombotic and bleeding complications. There are four risk categories for thrombosis in MPN patients: age, thrombosis history, and JAK -2 mutation...

BACKGROUND: Intracranial dural arteriovenous (AV) fistula classifications focus on presence/absence of retrograde flow in the cortical veins of the brain as this angiographic finding portends a worse prognosis. However, prior categorization systems of AV shunts in the spine do not incorporate these features. We propose an updated classification for spinal shunting lesions that terms any shunting lesion with retrograde flow in any cortical vein of the brain or spinal cord medullary vein as "high risk"...

BACKGROUND: Failure to achieve timely arteriovenous fistulae (AVF) utilization due to excessive depth (>6mm) remains an ongoing concern for dialysis access. This study evaluates the outcomes of radio cephalic (RCF) and brachiocephalic (BCF) fistula elevation required for access utilization. METHODS: A retrospective review of all patients undergoing first-time autologous access over 10 years was undertaken. RCF and BCF were analyzed, and cases of initial access failure due to depth alone were selected for study...

Hepatic portal venous gas is often referred to as the "sign of death" because it signifies a very poor prognosis if appropriate treatments are not promptly administered. The etiologies of hepatic portal venous gas are diverse and include severe complex abdominal infections, mesenteric ischemia, diving, and complications of endoscopic surgery, and the clinical manifestations are inconsistent among individual patients. Thus, whether emergency surgery should be performed remains controversial. In this report, we present three cases of hepatic portal venous gas...

Systematic review/meta-analysis of cumulative incidences of venous thromboembolic events (VTE) after metabolic and bariatric surgery (MBS). Electronic databases were searched for original studies. Proportional meta-analysis assessed cumulative VTE incidences. (PROSPERO ID:CRD42020184529). A total of 3066 records, and 87 studies were included (N patients = 4,991,683). Pooled in-hospital VTE of mainly laparoscopic studies = 0.15% (95% CI = 0.13-0.18%); pooled cumulative incidence increased to 0...

BACKGROUND: Evidence regarding the application of the multispectral camera for blood flow measurement is insufficient, and its performance has not been compared with the conventional indocyanine green (ICG) method. Therefore, we retrospectively compared the effectiveness of a new multispectral camera for non-invasive, real-time, quantitative imaging of tissue oxygen (O2 ) saturation and hemoglobin (Hb) levels and commercially available ICG fluorescence imaging in hemodynamic assessment of gastric tubes in esophagectomy...

INTRODUCTION: Dural arteriovenous fistula (DAVF) is an uncommon malformation involving an abnormal connection between dural arteries, or the pachymeningeal branches of cerebral arteries, and dural veins. Its exact pathogenesis remains elusive. Known potential triggers for DAVF include cerebral venous sinus thrombosis (CVST), trauma, ear infections, and cranial surgeries. Due to its rarity and diverse clinical presentations, diagnosing DAVF can be a challenge. CASE DESCRIPTION: We present a case of DAVF associated with CVST, manifesting as rapidly advancing parkinsonism accompanied by dementia over a month...

OBJECTIVES: Prolonged intubation (PI) is a frequently encountered severe complication among patients following cardiac surgery (CS). Solely concentrating on preoperative data, devoid of sufficient consideration for the ongoing impact of surgical, anesthetic, and cardiopulmonary bypass procedures on subsequent respiratory system function, could potentially compromise the predictive accuracy of disease prognosis. In response to this challenge, we formulated and externally validated an intelligible prediction model tailored for CS patients, leveraging both preoperative information and early intensive care unit (ICU) data to facilitate early prophylaxis for PI...

BACKGROUND Aortic dissection is rare after coronary artery bypass grafting (CABG). It is a potentially fatal complication of cardiac surgery. Reoperation may pose problems with thoracotomy, adhesiolysis, and myocardial protection. No standard treatment guidelines exist for chronic aortic dissection after CABG. We present a case of chronic type A aortic dissection after cardiac surgery, which was successfully treated. CASE REPORT A 65-year-old female patient presented with a medical background of hypertension, type 2 diabetes mellitus, and hyperlipidemia...

BACKGROUND: Autogenous arteriovenous fistula (AVF) is the preferred vascular access mode. However, the earliest possible time for AVF puncture and whether premature puncture affects the AVF patency rate remain unclear. METHODS: In this multicenter retrospective cohort study, adult uremic patients who underwent AVF surgery for the first time at Taizhou Hospital or Enze Hospital of Zhejiang Province between September 1, 2018 and August 31, 2021 were enrolled. All patients were followed up for 1 year after puncture, and the status of fistula establishment and puncture, subsequent patency, loss to follow-up, renal transplantation, conversion to peritoneal dialysis, abandonment of the fistula, and death, were recorded...

INTRODUCTION: Venous ulcers are a late and severe form of CVI and account for 70% of all etiologies that cause leg ulcers in the lower limb and they account for 20% of the 2.5 million cases complaining of chronic venous disease. Our study aims to investigate the effect of venous stenting of the deep veins on the healing of the venous ulcer. METHODS: This is a single-center, retrospective study conducted on prospectively recorded medical records of 78 patients with chronic deep venous diseases - C6 (either non-occlusive iliac venous lesion or post-thrombotic syndrome)...

PURPOSE: This study aims to conduct a comparative analysis of the clinical efficacy and safety between pharmacomechanical thrombectomy (PMT) and catheter-directed thrombolysis (CDT) in the context of acute lower-extremity deep venous thrombosis (LEDVT). MATERIALS AND METHODS: A retrospective review of our institution's patient database spanning from February 2011 to December 2019 was performed to identify cases of acute LEDVT. The patients were categorized into two distinct groups based on the thrombolytic interventions administered: the PMT group, specifically denoting PMT with AngioJet in our investigation, and the CDT group...

This retrospective study investigates to analyze the effect of RARC-ERAS nursing program on VTE and other clinical outcomes in patients undergoing RARC surgery. This retrospective study included 216 patients undergoing RARC surgery From January 1, 2022 to December 30, 2023, and propensity score adjustment analysis was applied. The study compares a control group receiving traditional nursing and an observation group receiving RARC-ERAS nursing program...

Varicosis is a chronic progressive disease characterized by varicose veins of the lower extremities. Pain, swelling and heaviness of the legs are typical symptoms. These symptoms are caused by a pathological venous reflux, arising from a weakness of the vein wall and progressive venous insufficiency. The indications for invasive surgery are the symptomatic clinical, etiological, anatomical, pathophysiological (CEAP) stages C2s-C6. Compression therapy and venoactive drugs can be recommended for conservative therapy...

Treatment of oral vascular anomalies (OVA) has focused on minimally invasive techniques rather than radical surgery. We investigated the efficacy and safety of diode laser using the photocoagulation technique in the management of OVA. Forty-seven subjects with OVA were treated with forced dehydration with induced photocoagulation (FDIP) using diode laser (808 nm/4.5 W). This series consisted mostly of male (63.8%) and non-white (63.8%) patients with a mean age of 57.4 years. Varices (91.5%), venous malformations (6...

BACKGROUND: Sparsity of recipient vessels poses a challenge for microsurgical free flap reconstruction of sternal defects following deep sternal wound infection after cardiac surgery. METHODS: From January 2013, a standardized algorithm for dealing with sparse recipient vessels was strictly followed. In this retrospective study including 75 patients, we compared operative details, surgical complications, and reconstructive outcomes of patients treated according to this algorithm (group A: January 2013-May 2021; n = 46) with a historical control group (group B: January 2000-December 2012, n = 29)...
