Arterial catheter

Temporary epicardial pacing wires (TEPWs) are widely used during open heart surgery to treat postoperative bradycardia or arrhythmia. They are usually removed, but the wire is cut at the skin entrance site if there is resistance upon removal. Residual TEPWs have risks of complications such as infection, but they rarely migrate to distant organs. We report a case of TEPW migration from the right ventricle to the pulmonary artery during the early stage after acute type A aortic dissection surgery. Residual TEPW migration was detected incidentally during follow-up imaging for aortic dissection, and no other complications, such as residual wire infection or thrombus, were noted...

CASE PRESENTATION: 42-year-old male presented with massive per rectal bleeding for one day duration. He is a known type 2 diabetes mellitus patient and not known to having any bleeding disorders or on any anticoagulant medication. He had no gastrointestinal red flag symptoms. He was hemodynamically stable, and rest of the examination was unremarkable...

BACKGROUND: Cardiogenic shock (CS), a complex and life-threatening medical condition, has an astounding hospital mortality rate spanning from 40 % to 59 %. Frequently, CS requires the use of pulmonary artery catheters (PACs) for management. OBJECTIVE: This literature review aims to investigate the relationship between PAC utilization in CS patients and in-hospital 30-day mortality rates compared to noninvasive vital sign monitoring alone. METHODS: An integrative literature search was conducted from January 1, 2003, until August 1, 2023...

PURPOSE: The purpose of this study was to evaluate the accuracy of peripheral oxygen saturation (SpO2) measurements from Polar ElixirTM pulse oximetry technology compared to arterial oxygen saturation (SaO2) measurements during acute stepwise steady state inspired hypoxia at rest. A post hoc objective was to determine if SpO2 measurements could be improved by recalibrating the Polar ElixirTM algorithm with SaO2 values from a random subset of participants. METHODS: The International Organization for Standardization (ISO) protocol (ISO 80601-2-61:2017) for evaluating the SpO2 accuracy of pulse oximeter equipment was followed whereby five plateaus of SaO2 between 70-100% were achieved using stepwise reductions in inspired O2 during supine rest...

Purpose: Specialized pressure transducers for arterial pulse waveform analysis (S-APWA) devices are dedicated kits connected to an arterial pressure catheter that monitors hemodynamic parameters, such as cardiac output, pulse pressure variation, and stroke volume variation, less invasively. While the association between the use of S-APWA devices and clinical outcomes in perioperative patients has been previously evaluated, its assessment in patients with septic shock remains inadequate. Materials and Methods: This retrospective cohort study utilized a nationwide Diagnosis Procedure Combination database in Japan...

The clinical management of coronary artery disease and the prevention of acute coronary syndromes require knowledge of the underlying atherosclerotic plaque pathobiology. Hybrid imaging modalities capable of comprehensive assessment of biochemical and morphological plaques features can address this need. Here we report the first implementation of an intravascular catheter system combining fluorescence lifetime imaging (FLIm) with polarization-sensitive optical coherence tomography (PSOCT). This system provides multi-scale assessment of plaque structure and composition via high spatial resolution morphology from OCT, polarimetry-derived tissue microstructure, and biochemical composition from FLIm, without requiring any molecular contrast agent...

BACKGROUND: There is insufficient information regarding the bleeding sites and surgical strategies of cardiac tamponade during catheter ablation for atrial fibrillation (AF). CASE PRESENTATION: Of the five patients with cardiac tamponade, three required surgical intervention and two required pericardiocentesis. In the first case of three cardiac tamponades requiring surgical intervention, considering that the peripheral route was used, the catecholamines did not reach the heart, and due to unstable vital signs, venoarterial extracorporeal membrane oxygenation (VA-ECMO) was inserted...

BACKGROUND: Hepatic artery infusion pump (HAIP) with floxuridine/dexamethasone and systemic chemotherapy is an established treatment regimen, which had been reported about converting 47% of patients with stage 4 colorectal liver metastasis from unresectable to resectable.1,2 To this effect, HAIP chemotherapy contributes to prolonged survival of many patients, which otherwise may not have other treatment options. Biliary sclerosis, however, is a known complication of the HAIP treatment, which occurs in approximately 5...

OBJECTIVE: To investigate the accuracy, precision, and trending ability of noninvasive bioreactance-based Starling SV and the mini invasive pulse-power device LiDCOrapid as compared to thermodilution cardiac output (TDCO) as measured by pulmonary artery catheter when assessing cardiac index (CIx) in the setting of elective open abdominal aortic (AA) surgery. DESIGN: A prospective method-comparison study. SETTING: Oulu University Hospital, Finland...

Arterial hypertension is a global leading cause of cardiovascular, cerebrovascular, and renal disease, as well as mortality. Although pharmacotherapy is safe and effective in lowering blood pressure (BP) and cardiovascular disease risk, BP control remains poor, and the mortality rates associated with high BP have been steadily increasing. Device-based therapies have been investigated to overcome barriers to pharmacotherapy, including non-adherence and low rates of persistence to daily medications. Among these device-based therapies, catheter-based renal denervation (RDN) has been most extensively examined over the past 15 years...

The Indigo Aspiration System (Penumbra Ltd., Alameda, CA, USA), a catheter-based device intended for the endovascular removal of clots from peripheral arteries and veins, was launched in Japan to treat acute limb ischemia after the cessation of urokinase sales. The initial application of this system in Japan was on a 96-year-old male patient. He was diagnosed with acute lower limb ischemia, which was caused by an embolism from a left common iliac artery aneurysm. The treatment significantly enhanced the perfusion to his left foot...

BACKGROUND: Treatment of calcified lesions with conventional angioplasty balloons can be difficult due to insufficient lumen expansion, high dissection rates, and repeated revascularization. We report a case in which a scoring balloon was used in lesions resistant to angioplasty with a semi-compliant balloon. CASE DESCRIPTION: A 72-year-old man presented with severe stenosis and a highly calcified lesion in the right cervical internal carotid artery. Right carotid artery stenting (CAS) was planned to prevent future ischemic stroke events...

BACKGROUND: The persistent primitive trigeminal artery (PPTA) is a persistent embryological carotid-basilar connection. Endovascular thrombectomy (EVT) for hypoplastic PPTA occlusion is a challenge. This case report aims to describe the successful recanalization of simultaneous occlusions in both the PPTA and basilar artery (BA) using the Solitaire FR (RECO SR)/Stent and Intermediate Catheter Assisting (SWIM) technique in a patient with acute cardiogenic cerebral embolism. To the best of our knowledge, this is the first report of such a case...

Selective intra-arterial radiotherapy (SIRT) is a technique which has evolved over the past 30 years. In present this is primarily used to treat primary and secondary tumors in the liver. The technique normally depends on the delivery of a therapeutic radiopharmaceutical or radiolabeled particulate via a radiologically placed intra-arterial catheter in the hepatic artery. This is because most of these tumors have a single arterial blood supply but normal hepatocytes are supplied by both the hepatic artery and portal vein...

OBJECTIVE: To describe the microvascular anatomy of the equine hind limb suspensory ligament. ANIMALS: 18 hind limbs harvested from 9 adult horses euthanized for reasons unrelated to lameness. METHODS: A catheter was placed in the transected cranial tibial artery at the level of the mid-distal tibia for each hind limb and used to inject 120 to 150 mL of contrast medium (2 limbs) to identify principal vasculature using contrast-enhanced CT or India ink (11 limbs) to identify microvasculature using the Spalteholz tissue-clearing technique...

We report a patient with history of recurrent invasive rectal adenocarcinoma complicated by obstructive uropathy requiring nephro-ureteral catheter placement. Two years later during a regular catheter exchange, the patient developed unusually bloody urine raising suspicion for possible vascular injury. CT angiogram and conventional angiogram were negative. However, an antegrade nephrostogram revealed a fistulous communication between the right ureter and the right internal iliac artery. Subsequently, the artery was sacrificed using detachable coils...

When starting a mechanical thrombectomy, manual aspiration with balloon guide catheters inserted into the internal carotid artery (ICA) is an efficient method for thrombus aspiration. However, no complications associated with this procedure have been reported. This study describes the case of a 76-year-old man who presented to our hospital with total aphasia and complete right-sided paralysis due to chronic atrial fibrillation and left occlusion of the ICA. When the balloon guide catheter was inserted and inflated at the origin of the left ICA, the patient's systolic blood pressure suddenly decreased from 114 mm Hg to 44 mm Hg...

A 39-year-old man presented for mechanical thrombectomy after receiving systemic tissue plasminogen activator (tPA) for a basilar artery occlusion. The anesthesiology team was initially unable to intubate the patient due to oropharyngeal bleeding and a large epiglottis. Two-handed, 2-provider mask ventilation with an oral airway proved difficult. The team successfully placed a supraglottic airway (SGA) through which an oral endotracheal tube (ETT) was advanced over a fiberoptic bronchoscope into the trachea...

BACKGROUND: Pulmonary embolism (PE) is the leading cause of in-hospital death and the third most frequent cause of cardiovascular death. The clinical presentation of PE is variable, and choosing the appropriate treatment for individual patients can be challenging. CASE SUMMARY: A 64-year-old man presented to hospital with acute chest pain, shortness of breath, and pulmonary oedema. Electrocardiogram revealed ST-elevation myocardial infarction. D-dimer was 18.8 mg/L fibrinogen equivalent units (FEU) (normal <0...
