Methods A total of 174 patients with coranaria disease from July 2003 to July 2009 were randomly divided into a control group and an observed group. The patients underwent the intervention treatment through femoral arteries in control group and through radial arteries in observed group. The duration and achievement rate of paracentesis and operation, and the incidence rate of complications were observed and the results in the two groups were compared. Results There were no differences in the duration and achievement rate of paracentesis and operation, and the achievement rate of operation between the control and observed groups. Compared with the control group, the incidence rate of complications and achievement rate of paracentesis were lower in observed group. Conclusion Intervention treatment through radial arteries on coranaria disease could reduce the post-operative complications with reliable therapeutic effect.
ObjectiveTo discuss the importance of early identification and effective management of puncture-associated complications after trans-radial percutaneous coronary procedures. MethodsA total of 698 patients undergoing trans-radial percutaneous coronary procedures from June to December 2012 were included and followed up. The puncture associated complications and their clinical managements were summarized in the present study. ResultsWe found that trans-radial approach was safe. The main puncture-associated complications included access-site pain, tension blisters and hemorrhagic complication. Complications with severe clinical consequence were rare. Most of the complications could be successfully treated with conservative management including access-site nursing and psychological nursing. ConclusionTrans-radial approach is safe for percutaneous coronary procedures, but close clinical monitoring and nursing are essential.
Objective To summarize the experiences of off-pump coronary artery bypass grafting (off-pump CABG) and on-pump coronary artery bypass grafting (onpump CABG) for patients with coronary artery diseases and to improve the surgical techniques and clinical results. Methods Coronary artery bypass grafting(CABG) were performed from January 2000 to March 2009 on 698 consecutive cases, including 551 male and 147 female with a mean age of 67.2 years(range, 28.0-79.0). There were 552 cases with angina pectoris and 131 with old myocardial infarction. Preoperative cardiac function showed 301 cases in New York Heart Association classⅡ, 339 in class Ⅲ,and 58 in class Ⅳ. Coronary angiography revealed single vessel disease in 21 cases, 2vessel disease in 87, 3vessel disease in 590, and 201 cases had concomitant left main lesions.There were 687 elective CABG and 11 emergency / urgent ones. Offpump CABG were performed on 346 cases and the others received onpump CABG . Results A total number of 2 025 grafts ( range,1-6 grafts, mean, 2.9 grafts /case ) were constructed with 693 left internal mammary arteries,115 free right mammary arteries,229 left radial arteries, and 81 right radial arteries. Total arterial bypass grafting was feasible on 126 cases. Postoperative ventilation duration varied from 0-127 hours (mean, 11.5 hours). Fasttrack procedure was offered to 38 cases with good results.Introaortic balloon pump support were provided to 1 patient preoperatively and 27 postoperatively. There were 25 deaths with a mortality of 3.64% for the elective cases with the cause of acute myocardial infarction ( 5 cases ), low cardiac output syndrome (3 cases),protamine reaction (2 cases),respiratory failure (3 cases), renal failure (2 cases),and multiorgan failure (10 cases).Four deaths occurred to urgent cases with a mortality of 36.36% from low cardiac output syndrome ( 3 cases) and acute myocardial infarction (1 case). One hundred and fiftyone cases（21.63%）developed atrial fibrilation among which 147（97.35%）returned to sinus rhythem with administration of electrolytes and Amiodarone. Resternotomy were performed for bleeding in 12 cases. Upon discharge from the hospital, 511 patients were free from angina while 20 other patients still had coexisting relieved angina. Postoperative followup was carried out on 415 cases（62.03%）for a period of 1month to 8.2 years with 3 deaths for lung cancer (1 case), car accident(1case), and unknown reasons (1 case). Number of patients who were free from angina was 317 and 21 for those who had recurrent angina. The cardiac function improved with 269 cases（65.29%）in New York Heart Association class Ⅱ, 142（34.46%）class Ⅲ, and 1（0.24%） class Ⅳ. Conclusion Good surgical results could be achieved with careful analysis of native Chinese patients’ coronary vessels, individualized operative plan, control of operative risk factors, and proper selection of bypass conduits. Aggressive use of IABP can provide essential support for patients with poor left ventricular function and other high risk factors.
With the development of interventional therapy technology, trans radial access (TRA) has gradually become the main approach of interventional therapy. Compared with trans femoral access (TFA), TRA has obvious advantages, which can shorten the time of lying in bed and reduce the incidence of complications. However, the radial artery is thinner than the femoral artery, the incidence of spasm is high, and the success rate of puncture is low, so the technical level of operation is required to be high. Nowadays, TRA has been gradually applied to lung cancer, aortic disease, hepatocellular carcinoma, spleen disease, renal artery disease, and other peripheral vascular diseases. With the confirmation of the safety and feasibility of TRA in interventional therapy in different fields, the popularization of TRA in different interventional fields will be supported.
Abstract: Objective To compare the effects of nitroglycerine (NTG)， Verapamil(VP), papaverine(PA) and the mixed solution of Verapamil and nitroglycerine (VG) on relaxing function of human radial arteries. Methods The radial arteries of thirty patients were used during the operation of coronary artery bypass grafting (CABG). A short segment (1.0-1.5cm) of radial arteris were taken from the distal end of radial arteries of each patient and were cut into vascular rings, which were mounted in the organ bath chamber and then subject to a series of tests for vascular smooth muscle viability and endothelial integrity. The effects of five storage solutions on the relaxing function were evaluated by “OrganBath” technique. The five solutions included: (1) Ringer’ s solution (control group); (2) VP solution (VP group); (3) NTG solution (NTG group); (4) PA solution (PA group); (5) VG solution (VG group). First, challenged with phenylephrine (10-5mol/L), vasorelaxant effect of these drugs (effect onset and efficacy) was observed at different time point and resting tension was recorded. Second, after 30min preincubation with either verapamil, papaverine, phenoxybenzamine or VG mixture, potassium chloride (final concentration of 60mmol/L) was added in the organ bath chamber and then vasoconstriction was observed subsequently. Finally, after 30min pretreatment of different antispasmodic agent in the same way as described above, the vascular rings were mounted in organ bath chamber and challenged with phenylephrine(10-5mol/L). Vascular spasticity and vosospasm duration were observed at different time point which might provide guidance for optimal timing of clinical application. Results The radial arteries in VG, VP, NTG and PA solutions were relaxed in 11 min after vasospasm and there was no difference between them (Pgt;0.05). But during the initial three minutes，the relaxation effect of VG and NTG was significantly better than other two groups. Relaxation curve showed that the ability of vasodilatation of VG, NTG, VP and PA decreased in order. In the experiment about antivasospasm pretreatment of radial arteries, there was no difference between VG and VP group (Pgt;0.05 ), whose effects were better than NTG and PA group(Plt;0.05 ). After cold storage for 24h, VG and VP still could prevent vasospasm. But NTG and PA hardly had any function and there was no difference compared with the control group (Pgt;0.05 ). Conclusion Although in the final all these drugs could prevent and relieve vasospasm of radial arteries in the different level, it appeared that a combination of verapamil and nitroglycenn is more fit for treating radial artery during CABG operation than other drugs.
ObjectiveTo explore the clinical application of the flap supported by perforating branch of the radial artery superior wrist catena-form blood vessel in repairing hand and wrist wound. MethodsBetween March 2010 and March 2013, 24 cases of severe wounds in wrist were repaired with the flap supported by perforating branch of forearm radial artery and catena-form blood vessel. There were 15 males and 9 females, aged 19-54 years (mean, 37 years). In 22 patients with trauma, there were 9 cases of machine injury, 5 cases of traffic accident injury, 5 cases of crash injury of heavy objects, 1 case of sharp instrument injury, and 2 cases of electrical injury, with a mean disease duration of 11 days (range, 2-20 days). In 2 patients with tumor excision wound, there were 1 case of right forearm liposarcoma and 1 case of left forearm squamous-cell carcinoma, with the disease duration of 7 days and 3 months, respectively. All cases complicated by bone and tendon exposure. The size of defect was 4.5 cm×4.0 cm to 10.0 cm×7.5 cm, and the size of the flap was 6.0 cm×4.0 cm to 20.0 cm×8.5 cm. The donor site was directly sutured or repaired by skin graft. ResultsPartial flap necrosis occurred in 1 case, and was cured after dressing change; the other flaps survived, and primary healing of incision was obtained. The patients were followed up 6-36 months (mean, 20 months). The flap featured good color and texture, and also recovered protective sensation at 6 months after operation, with a mean two-point discrimination of 12 mm (range, 11-14 mm). No ulcers of the flap was observed. At last follow-up, according to Hand Surgery Society of Chinese Medical Association for functional evaluation of upper limb, the function was rated as excellent in 19 cases, good in 4 cases, and fair in 1 case. ConclusionThe flap supported by perforating branch of forearm radial artery and catena-form blood vessel can be used to repair wound in wrist, which has no injury to the radial artery, and it also could be used for the patients with ulnar and radial artery injuries. Thus it is an ideal method to repair wound in the wrist because the operation is simple, and the flap has good appearance and texture.
Objective To investigate the clinical application of micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist to repair skin defect of finger. Methods Twenty-six cases (26 fingers) with skin defect of finger were repaired with micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist between December 2011 and February 2013. There were 20 males and 6 females with the average age of 31.5 years (range, 20-56 years). The causes of injury included cutting injury in 20 cases and crushing injury in 6 cases. The time from injury to admission was 1-5 hours with an average of 2 hours. Injured fingers included thumb in 6 cases, index finger in 6 cases, middle finger in 6 cases, ring finger in 4 cases, and little finger in 4 cases; the locations were the dorsal side of the finger in 6 cases, lateral side in 6 cases, and the volar of the finger tip in 14 cases; there were 4 cases on the proximal phalangeal skin, 8 cases on the middle phalangeal skin, and 14 cases on the distal phalangeal skin. The defect area ranged from 2.0 cm × 1.5 cm to 4.0 cm × 2.0 cm, and the flap area ranged from 2.5 cm × 2.0 cm to 4.5 cm × 2.5 cm. All the donor sites were directly sutured. Results The flaps of 25 cases survived well after operation, and wound healed by first intention； 1 case had partial necrosis and the wound had a scar healing by changing dressing. All cases were followed up 6-12 months (mean, 10 months). The color and appearance of the flaps were satisfactory with tender texture. The two-point discrimination of the flap was 5-8 mm (mean, 6.8 mm). The donor sites healed primarily without scar contracture and limitation of wrist flexion or extension. Conclusion The micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist is a good option to repair skin defect of finger. It has the advantages of hidden donor site, the same operative field, great comparability of flap and finger skin, and it can be used as a vascularized tendon or nerve graft.
