ABSTRACT
There have been many reports radial artery grafts (RA) are useful in CABG, but there were very few reports about hand grasping power (GP), edema and sensory disturbance after surgery. From January to April, 1999, RA were used for 14 patients (R group) and were not in 16 patients (C group) among a total of 30 coronary artery bypass grafting procedures. The patients in the two groups were statistically similar. RA were anastomosed to #12 in 9 patients and #14 in 5. GP and the circumference of forearms were examined and sensory disturbance was also checked preoperatively and at 1, 2 and 4 weeks postoperatively. In both groups, left GP decreased slightly after surgery but gradually recovered. Four weeks after surgery, it was 26.2±9.6kg in the R group and 26.2±7.5kg in the C group (NS). The difference between left and right circumference of forearms, which indicates the degree of edema, was significantly larger in the R group than in the C group (3.5±3.6mm vs. -0.5±3.8mm, 1 week postoperatively, <i>p</i><0.05). However, it gradually improved in the R group (2.1±2.6mm at 2 weeks and 1.9±2.6mm at 4 weeks postoperatively). No sensory disturbance was seen at any time. Therefore we conclude that using RA in CABG is not only useful but is also safe and does not increase postoperative risk.
ABSTRACT
Malignant hyperthermia (MH) and antithrombin III (AT III) deficiency are both rare, but once they occur, the patient's prognosis is very poor. A 67-year-old man was referred to our hospital with a diagnosis of unstable angina. A coronary angiography revealed stenosis of LMT and triple vessels. The patient was considered a candidate for CABG. He had been prescribed 50mg/day of dantrolene for frequent muscular convulsions of the lower extremities. He had had a high CK level for a few years. Therefore he was considered to be at high risk for malignant hyperthermia (MH). He underwent CABG (×4). Dantrolene was administered orally at a dose of 25mg and then 160mg intravenously before anesthesia and modified NLA was performed in order to avoid probable MH. During the operation, AT III deficiency was suspected because the reaction of ACT after heparinization was poor. AT III preparation (1, 500 units) was used and CABG under cardiopulmonary bypass was completed without any events. It was proved after the surgery that the AT III volume had been almost normal but its activity had decreased. His postoperative course was good. For possibly fatal MH and AT III deficiency, it is necessary and important to predict, prevent and diagnose as early as possible.
ABSTRACT
We performed a video-assisted thoracoscopic surgery (VATS) to clip the patent ductus arteriosus (PDA), which was 5mm in internal diameter, in an 11-year-old girl, who first underwent a coil embolization ending in failure. Under general anesthesia with one-lung ventilation in a right lateral decubitus position, four thoracostomies were made in the left hemithorax. The PDA was clipped by two titanium clips, the length of which is 11mm at closing. Transesophageal echocardiography confirmed the location of the PDA and the absence of a residual shunt. The patient showed neither left recurrent laryngeal nerve dysfunction nor hemorrhage after operation, and was discharged on the 9th postoperative day. The clipping of the PDA by VATS can be applied for PDA without calcification if the external diameter is up to 7mm. This technique was minimally invasive and reliable. It was excellent in terms of the high quality of life achieved by the patient.
ABSTRACT
A 57-year-old man underwent subtotal graft replacement of the thoracic aorta for aneurysms of both the ascending and descending aorta. On the 20th post-operative day, pus was found to be draining from the sternotomy wound. The wound was opened and irrigated with 2% Povidoneiodine solution for a total of 3 months. Culture of the pus from the irrigation revealed <i>Staphylococcus epidermidis</i>. When there were no clinical indications of infection and wound cultures were negative, the necrotic sternum and surrounding tissue were debrided and an omental graft was placed in the cavity. Upon follow-up examination, the patient is doing well 10 months after the initial surgery.
