INTRODUCTION: Laser and radiofrequency ablation are two thermal ablation methods currently widely used to treat lower limb venous insufficiency. However, very few studies have been conducted on the use of microwaves, a form of thermal ablation, for the treatment of small saphenous vein (SSV) insufficiency. This study aimed to examine the efficacy and safety of endovenous microwave ablation (EMA) for the treatment of SSV insufficiency. METHODS: The clinical data of 126 patients (126 lower limbs) with SSV insufficiency (SSV trunk reflux time ≥ 500 ms on lower limb color Doppler ultrasound) treated at the Surgery Department of The Sixth People's Hospital of Zhuji from January 2020 to June 2022 were analyzed retrospectively; 64 patients underwent EMA and 62 underwent endovenous laser ablation (EVLA)...

BACKGROUND: Patients with amyotrophic lateral sclerosis present perioperative challenges for clinical anesthesiologists for anesthesia-associated complications. CASE PRESENTATION: A 54-year-old Han woman with a 2-year history of amyotrophic lateral sclerosis was scheduled for hemorrhoidectomy and hemorrhoidal artery ligation. We performed real-time ultrasound-guided sacral plexus block with dexmedetomidine under standard monitoring. The anesthesia method met the surgical demands and avoided respiratory complications during the procedures...

INTRODUCTION: Chimney technique (chimney graft in abdominal aortic aneurysm repair [ChEVAR]) can be used to treat patients with pararenal aortic aneurysm unfit for open surgery and not suitable for custom-made fenestrated endograft. Since almost 1 in 5 patients undergo a reintervention within 3 years, features associated with higher risk of complications need to be investigated to tailor the follow-up schedule to each patient. The aim of our study was to assess the impact of mural thrombus in the pararenal aorta on perioperative and follow-up complications after ChEVAR...

BACKGROUND: Pneumothorax following shoulder arthroscopy, although rare, is documented in over 30 PubMed case reports as occurring during or within 10 hours post-procedure. CASE PRESENTATION: A fit septuagenarian underwent a two-hour arthroscopic rotator cuff repair with IV anaesthesia and laryngeal mask airway, without a nerve block. With one hour remaining of the operation, the patient had desaturation and hypotension. Lung sliding was absent on ultrasound and x-ray confirmed left-sided tension pneumothorax...

OBJECTIVES: Central venous catheterization is used widely in critical pediatric patients. The authors sought to compare the success rate and safety of ultrasound-guided subclavian vein cannulation performed via infraclavicular and supraclavicular approaches. DESIGN: The authors compared the success rate of the first puncture and other information for cannulation in the children with congenital heart disease requiring central venous catheterization who were assigned randomly to the supraclavicular approach group (group A) or infraclavicular approach group (group B)...

BACKGROUND: Postoperative pancreatic fistula (POPF) remains the most common and serious complication after distal pancreatectomy. Many attempts at lowering fistula rates have led to unrewarding insignificant results as still up to 30% of the patients suffer from clinically relevant POPF. Therefore, the development of new innovative methods and procedures is still a cornerstone of current surgical research.The cavitron ultrasonic surgical aspirator (CUSA) device is a well-known ultrasound-based parenchyma transection method, often used in liver and neurosurgery which has not yet been thoroughly investigated in pancreatic surgery, but the first results seem very promising...

PURPOSE: Point-of-care ultrasound (POCUS) allows for rapid bedside assessment and guidance of patient care. Recently, POCUS was included as a mandatory component of Canadian anesthesiology training; however, there is no national consensus regarding the competencies to guide curriculum development. We therefore aimed to define national residency competencies for basic perioperative POCUS proficiency. METHODS: We adopted a Delphi process to delineate relevant POCUS competencies whereby we circulated an online survey to academic anesthesiologists identified as POCUS leads/experts (n = 25) at all 17 Canadian anesthesiology residency programs...

The purpose of preoperative biliary drainage (PBD) is to reduce complications during the perioperative period. The extrahepatic bile duct comprises distal and hilar bile ducts and assessing the need for PBD must be considered separately for each duct, as surgical procedures and morbidities vary. The representative disease-causing distal bile duct obstruction is pancreatic cancer. A randomized controlled trial has revealed that PBD carries the risk of recurrent cholangitis and pancreatitis before surgery, thus eliminating the need for PBD when early surgery is feasible...

BACKGROUND Diaphragmatic thickness fraction (DTF), measured by ultrasound, can predict the occurrence of postoperative residual neuromuscular blockade (RNMB). We hypothesized that the utilization of diaphragmatic ultrasound during the postoperative awakening phase of anesthesia in patients offers a successful means of avoiding RNMB in a notably comfortable manner, as compared to the use of acceleromyograph. MATERIAL AND METHODS Patients who underwent elective thyroid cancer radical surgery were enrolled in this prospective clinical study...

INTRODUCTION: Hip fractures cause severe pain during positioning for spinal anesthesia (SA). Intravenous systemic analgesics can lead to various complications in elderly patients, hence peripheral nerve blocks are emerging as a standard of care in pain management for hip fractures, among which femoral nerve block (FNB) is widely known and practiced. Pericapsular nerve group (PENG) block is a recently described technique that blocks the articular nerves of the hip with motor-sparing effects and is used to manage positional pain in hip fractures...

BACKGROUND: With the increasing prevalence of colorectal cancer (CRC), optimizing perioperative management is of paramount importance. This study investigates the potential of stellate ganglion block (SGB), known for its stress response-mediating effects, in improving postoperative recovery. We postulate that preoperative SGB may enhance the postoperative recovery of patients undergoing laparoscopic CRC surgery. METHODS: We conducted a randomized controlled trial of 57 patients undergoing laparoscopic colorectal cancer surgery at a single center...

BACKGROUND: Perioperative hypotension is frequently observed following the initiation of general anesthesia administration, often associated with adverse outcomes. This study assessed the effect of subclavian vein (SCV) diameter combined with perioperative fluid therapy on preventing post-induction hypotension (PIH) in patients with lower ASA status. METHODS: This two-part study included patients aged 18 to 65 years, classified as ASA physical status I or II, and scheduled for elective surgery...

BACKGROUND: The shift towards outpatient total knee arthroplasties (TKAs) has led to a demand for effective perioperative pain control methods. A surgeon-performed "low"-adductor canal block (ACB) technique, involving an intraoperative adductor canal block, is gaining popularity due to its efficiency and early pain control potential. This study examined the transition from traditional preoperative anesthesiologist-performed ultrasound-guided adductor canal blocks ("high-ACB") to low-ACB, evaluating pain control, morphine consumption, first physical therapy visit gait distance, hospital length-of-stay, and complications...

Improvements in fetal ultrasound have allowed for the diagnosis and treatment of fetal diseases in the uterus, often though surgery. However, little attention has been drawn to the assessment of fetal pain. To address this gap, a fetal pain scoring system, known as the Fetal-7 scale, was developed. The present study is a full validation of the Fetal-7 scale. The validation involved two steps: i. four fetuses with indication of surgery were evaluated in three conditions perioperatively: acute pain, rest, and under loud sound stimulation...

PURPOSE: Partial nephrectomies in the salvage setting after ablative or surgical therapy remain challenging cases that are underreported in the literature (1-5).

This article provides a comprehensive analysis of modern techniques used in the assessment of cutaneous flaps in reconstructive surgery. It emphasizes the importance of preoperative planning and intra- and perioperative assessment of flap perfusion to ensure successful outcomes. Despite technological advancements, direct clinical assessment remains the gold standard. We categorized assessment techniques into non-invasive and invasive modalities, discussing their strengths and weaknesses. Non-invasive methods, such as acoustic Doppler sonography, near-infrared spectroscopy, hyperspectral imaging thermal imaging, and remote-photoplethysmography, offer accessibility and safety but may sacrifice specificity...

BACKGROUND: Pulmonary aspiration syndrome remains a significant complication of general anesthesia, particularly in unfasted patients. Gastric point-of-care ultrasound (POCUS) allows for both qualitative and quantitative assessment of gastric content, providing a safe and reliable method to assess gastric emptying and reduce the risk of aspiration during general anesthesia. METHODS: The survey was distributed to Belgian certified anesthesiologists and trainees between April 2020 and June 2021...

PURPOSE OF REVIEW: Surgical procedures on obese patients are dramatically increasing worldwide over the past few years. In this review, we discuss the physiopathology of predominantly respiratory system in obese patients, the importance of preoperative evaluation, preoxygenation and intraoperative positive end expiratory pressure (PEEP) titration to prevent pulmonary complications and the optimization of airway management and oxygenation to reduce or prevent postoperative respiratory complications...

A 9-year-old boy presented to the emergency department after noticing a painless mass on the right testicle during self-examination in the shower. On physical examination, both testes were mobile and painless, with the right testis twice as big as the left and exhibiting palpable resistance. Sonographic examination revealed a uniformly demarcated mass with a ventral protrusion on the right testis. Tumor markers and blood tests were normal. The testis was exposed inguinally and the tumor was enucleated, which revealed a dermoid cyst...
