transcatheter closure of modified blalock taussig shunt with gianturco grifka Vascular Occlusion device
Catheterization and Cardiovascular Interventions, 1999Co-Authors: Mark H Hoyer, Rafael A Leon, Jay F FrickerAbstract:A 15-year-old girl with previous repair of a complex cyanotic congenital heart defect had persistence of a modified left Blalock-Taussig shunt that could not be ligated at surgery. Six years later, antegrade delivery of a Gianturco-Grifka Vascular Occlusion Device resulted in complete closure of the shunt. Cathet. Cardiovasc. Intervent. 48:365-367, 1999.

effects of low load resistance training with Vascular Occlusion on the mechanical properties of muscle and tendon
Journal of Applied Biomechanics, 2006Co-Authors: Keitaro Kubo, Naokata Ishii, Teruaki Komuro, Noriko Ishiguro, Naoya Tsunoda, Yoshiaki Sato, Hiroaki Kanehisa, Tetsuo FukunagaAbstract:The present study aimed to investigate the effects of low-load resistance training with Vascular Occlusion on the specific tension and tendon properties by comparing with those of high-load training. Nine participants completed 12 weeks (3 days/week) of a unilateral isotonic training program on knee extensors. One leg was trained using low load (20% of 1 RM) with Vascular Occlusion (LLO) and other leg using high load (80% of 1 RM) without Vascular Occlusion (HL). Before and after training, maximal isometric knee extension torque (MVC) and muscle volume were measured. Specific tension of vastus lateralis muscle (VL) was calculated from MVC, muscle volume, and muscle architecture measurements. Stiffness of tendon-aponeurosis complex in VL was measured using ultrasonography during isometric knee extension. Both protocols significantly increased MVC and muscle volume of quadriceps femoris muscle. Specific tension of VL increased significantly 5.5% for HL, but not for LLO. The LLO protocol did not alter the stiffness of tendon-aponeurosis complex in knee extensors, while the HL protocol increased it significantly. The present study demonstrated that the specific tension and tendon properties were found to remain following low-load resistance training with Vascular Occlusion, whereas they increased significantly after high-load training.

cooperative effects of exercise and occlusive stimuli on muscular function in low intensity resistance exercise with moderate Vascular Occlusion
Japanese Journal of Physiology, 2004Co-Authors: Yudai Takarada, Tomomi Tsuruta, Naokata IshiiAbstract:To obtain insight into the relative contributions of exercise and occlusive stimuli to these muscular adaptations, the present study investigated the short- and long-term effects of varied combinations of low-intensity exercise and Vascular Occlusion. The subjects were separated into 3 groups (n = 6 for each group): low-intensity with Vascular Occlusion (LIO), low-intensity without Vascular Occlusion (LI), and Vascular Occlusion without exercise (VO). LIO and LI groups performed bilateral knee extension exercises in seated positions with an isotonic extension machine. In the LIO group, both sides of the thigh were pressure-occluded at the proximal end by means of a tourniquet during the entire session of exercise (approximately 10 min), whereas only the Occlusion with the same pressure and duration was given in the VO group. The mean Occlusion pressure was 218 +/- 8.1 mmHg (mean +/- SE). The exercise session consisted of five sets of exercise at an intensity of 10-20% 1RM and was performed twice a week for 8 wk. After the period of exercise training, isometric and isokinetic strengths at all velocities examined increased significantly in the LIO group (p < 0.05), whereas no significant change in strength was seen in the LI and VO groups. The increase in muscular strength in LIO was associated with a significant increase in the cross-sectional area of knee extensor muscles by 10.3 +/- 1.6%. The plasma growth hormone concentration measured 15 min after the session of exercise showed a marked increase only in LIO. The results showed that the low-intensity exercise and occlusive stimuli have cooperative effects in the long-term adaptation of muscle and an acute response to growth hormone.

Applications of Vascular Occlusion diminish disuse atrophy of knee extensor muscles
Medicine and science in sports and exercise, 2000Co-Authors: Yudai Takarada, Haruo Takazawa, Naokata IshiiAbstract:TAKARADA, Y., H. TAKAZAWA, and N. ISHII. Applications of Vascular Occlusion diminish disuse atrophy of knee extensor muscles. Med. Sci. Sports Exerc., Vol. 32, No. 12, 2000, pp. 2035‐2039. Purpose: We have previously shown that the combination of low-intensity resistive exercise and moderate Vascular Occlusion induces in humans a marked increase in growth hormone secretion and muscular hypertrophy. The present study investigated the effects of Vascular Occlusion on the size of thigh muscles in patients who underwent an operation for the reconstruction of the anterior cruciate ligament to see whether it attenuates the disuse muscular atrophy without any exercise combined. Methods: Two sessions of occlusive stimulus, each consisting of five repetitions of Vascular Occlusion (mean maximal pressure, 238 mm Hg) for 5 min and the release of Occlusion for 3 min, were applied daily to the proximal end of the thigh from 3rd to 14th days after the operation. Changes in the cross-sectional area (CSA) of thigh muscles were analyzed with magnetic resonance images taken on the 3rd and 14th day after the operation. Results: Without occlusive stimulus (control), the CSAs of knee extensors and flexors decreased by 20.7 6 2.2% and 11.3 6 2.6% (mean 6 SEM, N 5 8), whereas with the occlusive stimulus, they decreased by 9.4 6 1.6% and 9.2 6 2.6% (N 5 8), respectively. The relative decrease in CSA of knee extensors was significantly (P , 0.05) larger in the control group than in the experimental group. Conclusion: The results indicate that the occlusive stimulus
