A carotid artery resection and replacement including neck dissection are used as a method of treatment for head and neck cancer with infiltration into the carotid artery. The recent development of imaging technique makes it easy to estimate the detailed anatomical relationship between the tumor infiltration into the carotid artery, it's resection and replacement are indicated at radical neck dissection. To detect any possibility of cerebral ischemia at the time of ligation of carotid artery, a temporary occlusion test of internal carotid artery with a ballon catheter (balloon occlusion test) is performed. Recently, we performed a carotid artery resection and replacement using an artificial vessel Gore-Tex) in a case of neck cancer with infiltration into the carotid artery.

Lumbar spinal stenosis is a commonly treated with epidural injections of local anesthetics and corticosteroids, however, these therapies may relieve leg pain for weeks to months but do not influence functional status. Furthermore, the majority of patients report no substantial symptom change over the repeated treatment. Utilizing balloon catheters, we successfully treated with three patients who complained persistent symptoms despite repeated conventional steroid injections. Our results suggest that transforaminal decompression using a balloon catheter may have potential in the nonsurgical treatment of spinal stenosis by modifying the underlying pathophysiology.

This study aimed to identify the error rates in Catheter Calibration Mode, Auto Calibration Mode, and Segment Calibration Mode among many calibration modes as a quantitative evaluation tool used for predicting the diameter and length of balloon or stent in percutaneous intravascular balloon dilatation or stent insertion. Our experiment was conducted with Copper Wire of 2 mm × 80 mm (diameter × length) manufactured elaborately for quantitative evaluation in calibration and Metal Ball of 5, 10, 15, 30, and 40 mm and Acryl Phantom of 25 mm, 50 mm, 75mm, 100 mm, 125 mm, 150mm, 175 mm, and 200 mm. At each height, subtraction images were acquired with a cineangiograph and Stenosis Analysis Tool as a software provided by the equipment company was used for measurement. To evaluate the error rates in Catheter Calibration Mode, Copper Wire was put on each acryl phantom before shooting. Copper Wire of 2 mm in diameter was set as a diameter for catheter, and Copper Wire of 8 mm in length was measured with Multi-segments. As a result, the error rates appeared at 1.13 ~ 5.63%. To evaluate the error rates in Auto Calibration Mode, the height of acryl was entered at each height of acryl phantom and the length of 8 mm Copper Wire was measured with Multi-segments and as a result, the error rates appeared at 0 ~ 0.26%. To evaluate the error rates in Segment Calibration Mode, each metal ball on the floor of table was calibrated and the length of 8 mm Copper Wire on each acryl phantom was measured and the length of 8 mm Copper Wire depending on the changes of acryl phantom height was measured with Mutli-segments and as a result, the error rates appeared at 1.05 ~ 19.04%. And in the experiment on OID changes in Auto Calibration Mode, the height of acryl phantom was fixed at 100mm and OID only changed within the range of 450 mm ~ 600 mm and as a result, the error rates appeared at 0.13 ~ 0.38%. In conclusion, it was found that entering the height values in Auto Calibration Mode, among these Calibration Modes for evaluating quantitative vascular dimensions provided by the software was the calibration method with the least error rates and it is thus considered that for calibration using a metal ball or other objects, putting them in the same height as that of treatment sites before calibrating is the method that can reduce the error rates the most.

Background: Conservative treatment is performed for isolated anterior wall of the maxillary sinus fractures, in many cases when the fracture is clinically not severe and asymptomatic. Despite the absence of symptoms, complications such as sinusitis, rhinitis, and chronic purulent secretion may develop; therefore, successful reduction is required. We attempted to reduce the risk of complications using an alternative technique: reduction of the fracture with two urinary balloon catheters inserted through the maxillary ostium and fixation using fibrin glue, which minimizes the damage to the bony fragments and sinus mucosa. Methods: In this study, 38 patients who were diagnosed with an isolated anterior wall of the maxillary sinus fracture at our hospital between January 2014 and January 2017 were enrolled. The fracture site was exposed via the Caldwell-Luc approach followed by reduction through the insertion of two urinary balloon catheters using a nasal endoscope and fixation with fibrin glue. The sex, cause of fracture, physical examination, and presence of complications were examined and patient's medical records and facial bone computed tomography scans were analyzed. Results: Radiological evaluation showed that there was no evidence of collapsed reduction fragments. Although some patients had remaining symptoms of hypoesthesia (15%; 3 patients), there were no complications such as infection, rhinitis, sinusitis, and chronic purulent secretion at the surgical site. Conclusion: In this study, we present an alternative surgical technique using two urinary balloon catheters and fibrin glue for the successful reconstruction of an isolated anterior wall of the maxillary sinus fracture. This technique enables precise restoration with a reduced risk of complications.

It is important to choose which approaches should be used to correct the fracture if the operation is indication for surgery in patients with orbital floor fracture. Transorbital, transantral, and endonasal approaches are methods for correcting the orbital floor fracture. The approach needs to be considered the location of the fracture, the degree, the severity of the fracture, the least remaining patient's disability, and preference of the surgeon. We report a case of orbital floor fracture using transorbital approach and endonasal catheter ballooning to resolve the limitations of transorbital approach alone.

Eight dogs were presented with anal sacculitis with purulent exudates and/or open in the right or left anal sac. Patient dogs, ranging in size from 3-to-8 kg, were treated with closed anal sacculectomies, in which the balloon of a Foley catheter (No. 6, 1.5 ml) was used to facilitate surgical dissection of the sac. In all cases, the Foley catheter successfully distended the anal sac during its removal. Clinical signs associated with the diseased anal sac were abated In the all dogs for a follow-up period of one-to-three months. Anal sacculectomy is a good therapeutic option for cases of chronic anal sacculectomy or impaction. The use of a small Foley catheter to distend the anal sacs during surgery was easy, Inexpensive, and successful.

The purpose of this study was to evaluate the absorbed dose to the coronary artery segment from various sized balloon angio catheters. The liquid form of Ho-166 was produced at the KAERI by (n, ${\gamma}$ ) reaction. We used GafChromic film for the estimation of the absorbed dose by beta particles. The exposed films were read using a videodensitometer. Several film exposures were made with varying irradiation times and activities. A modified micrometer was used for the measurement of the absorbed dose distribution near the balloon surface. Four balloons of coronary catheters evaluated were 30 m long and 2.5, 3.0, 3.5 and 4.0 mm in diameter. All doses are plotted in units of Gy/min/GBq/ml as a function of radial distance in mm from the surface of balloon. The absorbed dose rate was 0.86, 1.01, 1.11 and 1.24 Gy/min/GBq/ml at a balloon surface for various balloon diameter 2.5, 3.0, 3.5 and 4.0 mm respectively. Using a vacuum pump, the air in the balloon was evacuated prior to instillation of the Ho-166 source. By removing air bubbles in the balloon, the absorbed dose distribution was more uniform.

Background: We assessed the efficacy of intraoperative intra-aortic balloon pump therapy for achieving hemodynamic instability during off-pump coronary artery bypass surgery. Material and Method: We studied seven hundred ninety-six patients who underwent off-pump coronary artery bypass between January 2000 and December 2006. The patient were divided into group I (n=39), which received intraoperative intra-aortic balloon pump therapy, and group II (n=757), which did not receive intraoperative intra-aortic balloon pump therapy. Result: There were no differences in the operative mortalities (2.6%, 1/39 vs 0.8%, 6/757; p=0.195) and morbidities such as atrial fibrillation (p=0.691), stroke (p=0.908) and mediastinitis (p=0.781) between the 2 groups, although the ventilator support time, the length of the intensive care unit stay and the length of the hospital stay were longer in group I than in group II (p<0.05). Multivariate analysis failed to prove that group I was a high risk group for operative mortality (p=0.549). There were 3 intraoperative intra-aortic balloon pump-related complications in group I (7.9%). However, no longer complications occurred after 2003, when the surgeons began using a smaller sized 8 F catheter that was inserted using a sheathless technique. Conclusion: Intraoperative intra-aortic balloon pump therapy for achieving hemodynamic instability during off-pump coronary artery bypass surgery can be performed safely and it showed comparable clinical results to that of not using intraoperative intra-aortic balloon pump therapy.
