Air embolism is often an iatrogenic complication which may occur in venous or arterial circulation depending on the port of entry. We present two cases in which air embolism occurred in venous and arterial circulation after contrast medium injection (CMI) and coronary artery bypass graft (CABG) surgery, respectively. In one case, accumulation of air bubbles was observed in the pulmonary artery after CMI. This was attributed to inadvertent injection of air owing to improper connection of the injector and the catheter...

AIM: The feasibility of videoscopic inguinal-iliac-obturator lymphadenectomy (VIIOL) was assessed in 20 patients with melanoma and compared with a retrospective sample of 24 patients undergoing standard 'open' technique (IIOL). RESULTS: No postoperative death occurred; the mean operative time was lower in the IIOL series (190 min vs. 302 min) but the quality of life was greatly improved in the VIIOL group thanks to earlier bladder catheter removal, no nasogastric suction, less pain, earlier mobilization, lower in-hospital stay, and earlier resumption of daily activities (27...

BACKGROUND: Although the use of temporary shunts in proximal extremity amputations has been reported, no study has described the use of temporary shunts in distal extremity amputations that require vein grafting. Moreover, the total volume of blood loss when temporary shunts are used has not been reported. The aim of this study was to investigate the applicability of a temporary shunt for distal extremity amputations requiring repair by vessel grafting with an ischemia time of >6 hours...

With the recent advent of suction catheters, the use of manual aspiration thrombectomy (MAT) for patients with acute ischemic stroke with large vessel occlusion has increased. Although contrast leakage and subarachnoid hemorrhage have been reported during MAT procedures, pseudoaneurysm formation due to vessel injury by suction catheters has not been. We discuss the case of a 60-year-old woman who presented to our emergency room with dysarthria and left-sided weakness. She underwent suction thrombectomy 5 times for acute middle cerebral artery occlusion and significant contrast leakage occurred during the procedure...

BACKGROUND: The benefits of mechanical thrombectomy for emergent large vessel occlusion (ELVO) have been established. Combined mechanical/aspiration (Solumbra) and a direct aspiration as a first pass technique (ADAPT) are valid procedures requiring an intermediate catheter for clot suction. Recently, SOFIA (Soft torqueable catheter Optimized For Intracranial Access) was developed as a single lumen flexible catheter with coil and braid reinforcement, but its suitability for mechanical thrombectomy had not been evaluated...

Stripped of any sense of comfort or dignity on that hospital bed, my 84-year-old father, my best friend, was enduring raw, intrusive medical procedures against his own wish; defenseless, vulnerable, agonized. A feeding tube went in through his nose; catheter tubes drained urine out of his bladder; a suction pump drew out fluid from his airway. A needle jammed into the central line, making it impossible for him to turn his head. Dialysis took over the job of his kidneys. But no painkillers were given for fear his weak heart could not take more chemicals...

BACKGROUND: Keeping the operating field clean and visible is an important technique in neurosurgery. Continuous irrigation-suction (IS) of the surgical field is currently often done using devices available that are expensive and demand technical proficiency. We report a simple method of continuous ISusing widely available central venous catheter and controlled suction cannula. METHODS: We used a controlled suction cannula attached to a central suction system. Single lumen central venous catheter is passed through the key hole of a controlled suction cannula, which is connected to a continuous irrigation system...

We propose a mechanism of how stroke may be caused by thrombus aspiration during primary percutaneous coronary intervention (PPCI), and how it may be technique-dependent. Two recent meta-analyses report increased risk of stroke in patients undergoing routine thrombus aspiration during STEMI and the value of this technique has been controversial. The mechanism of stroke has not been fully explained. This case demonstrates 2 mechanisms by which aspiration might cause thrombus embolization. We recommend that if thrombus aspiration is performed during PPCI for STEMI, it should be done selectively and carefully...

BACKGROUND: Surgical clipping of paraclinoid aneurysm can be very difficult because strong adhesions may hinder the dissection of the perforators and surrounding anatomical structures from the aneurysm dome. We describe our experience with using retrograde suction decompression during the clipping of paraclinoid aneurysms and discuss the relative advantages and pitfalls. MATERIALS AND METHODS: This study included 23 patients with large and giant paraclinoid aneurysms who underwent surgical treatment consisting of direct clipping with suction decompression between March 2004 and August 2014...

OBJECTIVE Reservoirs integrated into hydrocephalus shunts are commonly used for the removal of CSF and for intra-ventricular pressure measurement. Pumping with the reservoir to diagnose shunt sufficiency is still a matter of controversy. The authors describe an improved flushing device and its characteristic features in vitro and in vivo. METHODS The flushing reservoir is constructed with a sapphire ball in a cage as a nonresistance valve to also enable the detection of distal occlusions. The most important reservoir parameters were investigated in vitro, simulating total and partial proximal and distal shunt occlusions...

BACKGROUND: Wave intensity analysis can distinguish proximal (propulsion) and distal (suction) influences on coronary blood flow and is purported to reflect myocardial performance and microvascular function. Quantifying the amplitude of the peak, backwards expansion wave (BEW) may have clinical utility. However, simultaneously acquired wave intensity analysis and left ventricular (LV) pressure-volume loop data, confirming the origin and effect of myocardial function on the BEW in humans, have not been previously reported...

BACKGROUND AND AIMS: EUS-guided FNA biopsy has been widely performed to aid in the diagnosis of submucosal tumors (SMTs). However, in cases of small tumors, the diagnostic yield of EUS-FNA is poor. Therefore, it is necessary to develop a new needle for the diagnosis. We developed a device with a new mechanism that we refer to as a drill needle aspiration biopsy (DNAB). The aim of this study was to evaluate the use of DNAB in resected gastric SMT specimens. METHODS: A drill needle with a sharp tip and wide ditch was inserted into a catheter for angiography...

BACKGROUND: The insertion of suction devices through endotracheal tubes (ETTs) increases airway resistance and the subsequent suctioning may reduce airway pressures and facilitate atelectasis. The aim of this study was to investigate how airway pressures and tidal volumes change when different combinations of suction equipment and ETT sizes are used, and to what extent unfavorable effects can be ameliorated by choice of ventilator settings. METHODS: A mechanical ventilator was connected to a lung model by ETTs of 9 mm, 8 mm or 7 mm internal diameter (ID) with a pressure transducer inserted distal to the ETT...

Hemostasis is a critical point in endoscopic sinus and skull base surgery. A variety of techniques are presently available for reducing intraoperative bleeding; however, several limitations of the classical instruments should be stated. For example, reaching bleeding points in an anatomically angled site with straightforward bipolar devices could be quite difficult. With the aim of solving this problem, we developed a simple system using a standard curved suction tube, a rubber catheter and a monopolar system...
