First results of the use of a novel method of percutaneous coronary angioplasty of chronic occlusions of coronary arteries are presented. In 8 patients (men aged 54 - 75 years, mean age 60,4 +/- 7.1 years, mean duration of occlusion 45.5 +/- 7.9 months) retrograde recanalization was carried out through collateral branches of right coronary artery (RCA, 6 patients) or left anterior interventricular artery (LAIA, 2 patients). In all cases the procedure was preceded by unsuccessful attempts of antegrade recanalization of occlusion. Retrograde intervention was successful in 6 of 8 cases (5 RCA, 1 - LAIA). Technique of retrograde recanalization is described, criteria of selection of collateral branch, and instrumentation for optimization of the method are presented. As collateral branch in 6 cases we used septal branches either from LAIA (in case of recanalization of RCA) or from posterior interventricular branch of RCA (intervention on LAIA). In 2 cases retrograde recanalization of RCA was performed through posterior-lateral collateral branch of the circumflex artery. 相似文献

Angiography with a pre-diagnosis of acute coronary syndrome was performed in a 76-year-old female patient presenting to another hospital with symptoms of chest pain and syncope. Upon determination of type III aortic dissection, the patient was referred to our clinic. On CT angiography, the ascending aortic diameter was 57 mm and no dissection flap was observed. There was a filling defect suggestive of intimo–intimal intussusception at the level of the aortic arch, occlusion of the left arteria carotid communis, and a double-channel aorta extending from the left subclavian artery to the iliac artery. On transoesophageal echocardiography, the ascending aorta was seen to be larger than normal and no dissection flap was observed. There were findings suggestive of haematoma and intimo–intimal intussusception at the proximal part of the aortic arch. The dissection flap causing occlusion in the vascular structures was resected. Supracoronary graft replacement of the ascending aorta was performed. Transoesophageal echocardiography is an invasive investigative method with high sensitivity and specificity for the diagnosis of intimo–intimal intussusception. 相似文献

STUDY OBJECTIVES: To determine if transcutaneous electrical nerve stimulation (TENS) can produce fingertip analgesia. DESIGN: Randomized, crossover trial. PARTICIPANTS: Fifteen healthy volunteers, naive to the technique of TENS. INTERVENTIONS: TENS stimulation was applied to the middle and ring fingers of each subject's hands by means of small carbon electrodes placed over the digital nerves. Patients received one fingertip puncture from a mechanically driven sterile lancet device to each digit corresponding to one of four conditions: sham, one minute of TENS, ten minutes of TENS, and 20 minutes of TENS. The TENS unit was operated in the "burst" mode, with two eight-pulse burst groups per second (pulse width, 225 mu sec; pulse frequency, 80 Hz). The order of the conditions and the finger used for each condition were assigned randomly. The pain of each puncture was rated on a 10-cm visual-analog scale. Data were analyzed using a repeated-measures analysis of variance with Duncan's multiple comparisons procedure. MEASUREMENTS AND RESULTS: Mean visual-analog scale scores decreased sequentially from sham in each experimental condition: one minute of TENS, 24.4% (P < .025); ten minutes of TENS, 28.2% (P < .025); and 20 minutes of TENS, 55.7% (P < 10(-6)). Two patients had total anesthesia of the fingertip (visual-analog scale = 0 cm) in the 20-minute TENS condition. CONCLUSION: TENS significantly reduces the pain of lancet-induced trauma to the fingertip. Further studies are warranted to determine if this technique is useful clinically as an alternative or adjunct to digital nerve block anesthesia for fingertip surgical procedures. 相似文献

A new concept of hepatic segmentation along with the Glissonean pedicle tree, and the basis of hepatic resection by the Glissonean pedicle transection method are presented. The portal triad continues from the hepato-duodenal ligament to the intra-hepatic portion as the Glissonean pedicle. That is, the artery, portal vein and bile duct, together with connective tissue, are sheathed by the peritoneum to form a fibroid bundle. The entire length of the primary branches of the Glissonean pedicle and the origin of the secondary branches are located outside the liver and the trunks of the secondary and more peripheral branches run inside the liver. The ramification pattern of the tertiary branches which branch out from each secondary branch is different from patient to patient. The liver is nourished by the secondary branches of the Glissonean pedicle. Each secondary branch feeds one segment. The liver can thus be separated into three segments and an additional caudate area. The area fed by each one of the tertiary branches is cone-shaped; fermed a “cone unit”. Each segment conists of six to eight cone units. In limited resections, the number of cone units to be respected is adjusted and the tertiary branches which feed these areas must be transected selectively through a hilar or a parenchymal approach. To date we have experienced no complications with this procedure, employed for 832 patients with hepatocellular carcinoma. 相似文献

Digital vasculopathy and subsequent digital ulceration are common and painful complications of limited cutaneous systemic sclerosis. Although the use of hydrocolloid occlusive dressings has been found to reduce pain, frequently required surgical or chemical debridement can be intensely painful in such ulcers. Acoustic pressure wound therapy is a noncontact, low-frequency ultrasound therapy used for painless debridement in a variety of acute and chronic wounds. It was administered to treat an intensely painful, methicillin-resistant Staphylococcus aureus-infected finger ulcer resulting from peripheral, bilateral vasculopathy in a 68-year-old man with a history of three prior fingertip amputations secondary to limited cutaneous systemic sclerosis-associated digital vasculopathy. At treatment initiation, 90% of the 11 cm2 wound was covered with firmly adherent fibrin slough. Acoustic pressure wound therapy was performed three times weekly for 5 minutes per treatment and the wound was covered with a hydrocolloid occlusive dressings. Pain scores decreased from 10 (visual analog scale, 0 = none, 10 = extreme) at the beginning of treatment to 0 at the week 8 assessment and his analgesics were discontinued. After 10 weeks (31 acoustic pressure wound therapy treatments), the wound was completely closed. 相似文献

Electrophysiological studies demonstrate the existence of chemo- and baroreceptors in the dorsal carotid artery of the tortoise, Testudo hermanni Gmelin. A fine nerve branch, 5-7 microns in diameter, originates from the glossopharyngeal nerve and terminates in the part of the dorsal carotid artery between its origin at the subclavian artery and the bifurcation of the tracheal branch. When afferent impulses were recorded from this fine nerve simultaneously with the blood pressure, two kinds of activity were observed. One, synchronous with blood pressure fluctuation, appears to originate in baroreceptors. The other, non-rhythmic, consisted of an increase of impulse frequency to hypoxia, hypercapnia and NaCN, characteristics of an arterial chemoreceptor. Thus this fine nerve seems to correspond to the mammalian carotid nerve. Afferent innervation of the truncal region including the aorta and the pulmonary artery was nearly the same as that in some turtles. 相似文献
