BACKGROUND/AIMS: Brain shift during the exposure of cranial lesions may reduce the accuracy of frameless stereotaxy. We describe a rapid, safe, and effective method to approach deep-seated brain lesions using real-time intraoperative ultrasound placement of a catheter to mark the dissection trajectory to the lesion. METHODS: With Institutional Review Board approval, we retrospectively reviewed the radiographic, pathologic, and intraoperative data of 11 pediatric patients who underwent excision of 12 lesions by means of this technique...

Radiofrequency catheter ablation is increasingly being used to treat patients who have ventricular tachycardia, and anesthesiologists frequently manage their perioperative care. This narrative review is intended to familiarize anesthesiologists with preprocedural, intraprocedural, and postprocedural implications of this ablation. Ventricular tachycardia typically arises from structural heart disease, most often from scar tissue after myocardial infarction. Many patients thus affected will benefit from radiofrequency catheter ablation in the electrophysiology laboratory to ablate the foci of arrhythmogenesis...

BACKGROUND: Liver metastases are relatively common in patients with metastatic medullary thyroid carcinoma (MTC), carrying a negative impact on disease prognosis. The options for selective therapy of liver metastases in MTC patients are limited to catheter guided procedures such as trans-arterial chemoembolization (TACE). Data regarding the effectiveness and safety of this procedure in MTC is limited. AIM: To explore the clinical outcome, survival and safety profile of TACE for liver metastases in a group of MTC patients...

The increased popularity of paravertebral block (PVB) can be attributed to its relative safety and comparable efficacy when compared with epidural analgesia. It has thus been recommended for open cholecystectomy and other less painful surgeries such as inguinal herniorraphy and appendectomy. We performed a systematic review of PVB in paediatric abdominal conditions to assess its clinical efficacy and side effects compared with other analgesic therapies.A search of Medline, Embase, and Web of Science and hand-searching references from inception date to May 2016 was done...

Totally subcutaneous intravascular portals have been increasingly used to administer long-term chemotherapy and parental nutrition. The reported complications are rare. Accidental endovascular rupture of a fragment of catheter is one of the most formidable complications of the central vein catheterization. The Authors report a case of deployment of a Port-a-Cath catheter and its percutaneous retrieval. The catheter accidentally detached and migrated from the reservoir of the port-a-cath placed in the left subclavian vein to the right heart cavities through the blood stream...

PURPOSE: We have discussed the diagnosis and treatment approaches in patients with discontinued (disconnected or fractured) ventriculoperitoneal (VP) shunts that caused mechanical dysfunction. METHODS: Between 2006 and 2016, VP shunt surgery was performed on 1357 pediatric patients in our clinic. In follow-up examinations, we retrospectively reviewed patients who underwent revision surgery. Except for diagnosis of discontinued VP shunt, by excluding revision-surgery patients, only those patients who underwent surgical treatment owing to discontinued (fracture or disconnection) catheter were included in the study...

BACKGROUND: The majority of incident hemodialysis (HD) patients initiate dialysis via catheters. We sought to identify factors associated with initiating hemodialysis with a functioning arterio-venous (AV) access. METHODS: We conducted a retrospective chart review of all adult patients, age >18 years seeing a nephrologist with a diagnosis of CKD stage 4 or 5 during the study period between 06/01/2011 and 08/31/2013 to evaluate the placement of an AV access, initiation of dialysis and we conducted a survey of providers about the process...

Lower-extremity ischemia is a significant complication in children on femoral venoarterial extracorporeal membrane oxygenation (VA ECMO). Our institution currently routinely uses distal perfusion catheters (DPCs) in all femoral arterial cannulations in attempts to reduce ischemia. We performed a single-center, retrospective review of pediatric patients supported with femoral VA ECMO from January 2005 to November 2015. The outcomes of patients with prophylactic DPC placement at cannulation (prophylactic DPC) were compared to a historical group with DPCs placed in response only to clinically evident ischemic changes (reactive DPC)...

BACKGROUND: Rectal leiomyosarcoma (LMS) is an extremely rare disease. Previously, LMS was not properly distinguishable from gastrointestinal stromal tumor (GIST) until c-kit, a characteristic marker of GIST, was discovered in 1998. No standard therapeutic strategy for gastrointestinal LMS has been established except for surgical resection because of its rarity. Rectal LMS is often accompanied by symptoms, which can enable detection at a small size. However, when a large LMS is detected at the lower rectum, it is difficult to excise due to the narrow pelvic space...

AIMS: Adenosine may unmask dormant PV conduction and facilitate consolidation of PV isolation. We performed a meta-analysis to determine the impact of adenosine administration on clinical outcomes in patients undergoing PVI. METHODS: References and electronic databases reporting AF ablation and adenosine following PVI were searched through to 22nd November 2015. The impact of adenosine on freedom from AF was assessed in twenty publications after radiofrequency ablation (RFA), and in four publications after cryoablation to achieve PVI...

BACKGROUND AND OBJECTIVES: Venous thromboembolism (VTE) is a common cause of preventable harm. Perioperative thoracic epidural analgesia (TEA) presents a challenge to optimal VTE prophylaxis. Our primary aim was to characterize missed doses of VTE prophylaxis associated with epidural catheter placement and removal. Our secondary aim was to measure the effect of an enhanced recovery after surgery (ERAS) pathway on the rate of TEA-associated missed VTE prophylaxis. METHODS: We retrospectively reviewed a prospectively collected database of 1264 colorectal surgery patients at a single academic center...

Anticoagulation after a recent neuraxial procedure poses risk for development of spinal hematoma. Clinical evidence supports prompt IV tissue plasminogen activator administration after onset of ischemic stroke. There is an absence of data regarding emergency fibrinolytic therapy for patients experiencing a stroke with recent neuraxial procedures, resulting in highly disparate, nonevidence-based guidelines. This report describes a patient who developed ischemic stroke when receiving postoperative epidural analgesia...

PURPOSE: Epidural anesthesia and analgesia has a reported failure rate ranging from 13% to 32%. We describe a technique using colour Doppler and M-mode ultrasonography to determine the position of the epidural catheter after placement in adults. METHODS: This retrospective review included 37 adult patients who received postoperative epidural analgesia and underwent technically difficult epidural catheter placement. The demographic characteristics, type of surgery, use of ultrasonography, method of insertion, intervertebral level, and success of epidural localization using colour Doppler were noted for each patient...

Vasopressors are an integral component of the management of septic shock and are traditionally given via a central venous catheter (CVC) due to the risk of tissue injury and necrosis if extravasated. However, the need for a CVC for the management of septic shock has been questioned, and the risk of extravasation and incidence of severe injury when vasopressors are given via a peripheral venous line (PVL) remains poorly defined. We performed a retrospective chart review of 202 patients who received vasopressors through a PVL...

Cord trauma is a risk with a cervical and thoracic interlaminar epidural approach to the epidural space. Intermittent lateral fluoroscopic imaging to detect needle depth is often cumbersome and may be difficult to interpret. In comparison, the contra-lateral oblique (CLO) fluoroscopic view is efficient and easy to interpret. However, the in vivo reliability and safety of this technique has not been formally investigated.The senior author collected fluoroscopic images on 278 consecutive patients undergoing an interlaminar epidural block at the T1-T2 level performed using a 17 gauge Tuohy needle...

It is almost a quarter of century that a pioneering work of 2 researchers named Brugada brought the entire scientific community to understanding the molecular, clinical, and electrophysiological aspects of a distinctive syndrome. It affects mainly young adults with syncope and/or sudden cardiac death caused by polymorphic ventricular tachycardia or ventricular fibrillation in the absence of any sign of cardiac degeneration or alteration. Although the involvement of the epicardial layer of the right ventricular outflow tract, and the requirement of pharmacologic challenge for unveiling concealed forms, have been fully characterized, many areas of uncertainties remain to be elucidated, such as the unpredictable usefulness of programmed ventricular stimulation, the role of radiofrequency catheter ablation for reducing ST-segment elevation, and the value of risk stratification in patients diagnosed with upper displacement of right precordial leads...
