PULMONARY BLOOD DISTRIBUTION AFTER TOTAL CAVOPULMONARY CONNECTION OF DIFFERENT TYPES 总被引:2,自引:0,他引:2
Objective. To assess the feature of pulmonary blood flow distribution after total cavopulmonary connection (TCPC) of different types, and to provide the selection of the best type .Methods. Thirty-two consecutive survival patients after TCPC underwent radionuclide lung perfusion imaging. According to the radionuclide counts in the left and right lungs, analyses of the distribution of blood flow from superior venous cava (SVC) and inferior venous cava (IVC) and the whole pulmonary blood flow in both lungs were made. All patients were divided into 4 groups by the the anastomosis between IVC and pulmonary artery.Results. Group Ⅰ: The flow ratio of the IVC to left lung was greater than that to the right lung , P≤0. 01; the flow ratio of the SVC to right lung was greater than that to the left lung, P≤0. 01; and the whole pulmonary blood flow went dominantly to the left lung, P≤0. 05, which is not in line with physiological distribution. Group Ⅱ: the flows from the SVC and IVC were mixed in the middle of 相似文献

We report a prospective trial comparing the effectveness of a post-operative flexion regime versus a standard extension regime
on the early outcome and on the post-operative blood loss of total knee arthroplasty. Fourty-eight knees were divided to two
different post-operative rehabilitation regimes: a flexion regime and an extension regime. The two groups were well matched
with respect to age, gender, operation side and pre-op diagnosis All patients were implanted with a NexGen cemented total
knee prosthesis and all operations were performed by the same surgeon. Patients were assessed pre-operatively, at the time
of discharge, at 6 weeks and at 12 weeks, and were evaluated by means of the Knee Society Score (KSS) and the WOMAC score,
the Clarkson criteria for range of motion and muscolar strength measurement, and the Verbal Numeric Scale (VNS) for the pain.
Futhermore, postoperative blood loss was assessed by comparing the volume of blood in the drain at the time of their removal
and measuring the difference in preoperative and postoperative blood haemoglobin (Hb) in the 2 groups. Patients subjected
to the flexion regime had a better KSS and Womac score after 12 weeks and had less post-operative blood loss, requiring fewer
blood transfusions. No differences were found between the two groups in terms of pain and muscolar strength. We believe a
flexion regime after a total knee arthroplasty is a valid option of rehabilitation treatment and does not result in an increase
in wound problems. 相似文献

We examined the clinical and radiographic results of 93 patients affected by knee arthritis or osteonecrosis subjected to
unilateral cementless mobile-bearing total knee arthroplasty with the LCS prothesis (Depuy/Johnson & Johnson). The mean follow-up
was 9.5 years (range, 7–12 years). Clinical evaluation was performed using the Knee Society rating system, while radiographic
evaluation was done according to the Knee Society roentgenographic system. At the latest follow-up, the mean knee score was
87 points: the functional score improved from 40 to 90. Radiolucent lines were small and not progressive. The implant survival
at 12 years was 88%. Six knees (7%) required revision for implant-related problems. We conclude that the mobile-bearing prosthesis
is a successful device even at long-term follow-up. 相似文献

Unicompartmental knee arthroplasty (UKA) is considered the treatment of choice in patients with single compartment arthritis
of the knee at early stages or with osteonecrosis limited to one compartment. However, results in the literature are still
controversial and it is a technically difficult procedure. The main goal of UKA is to restore the articular space of the afflicted
compartment, without influencing the limb alignment. Selection of patients and pre-operative planning are crucial. The necessity
to improve functional results and to reduce immobilization of the patients has led to the development of minimally invasive
surgery. Applied to UKA, this approach reduces blood loss and surgical time, causes fewer symptomatic postoperative complications,
and permits earlier recovery compared to the traditional incision. The shorter incision makes careful pre-operative planning
essential. We briefly review the indications for UKA, the pre-operative clinical and radiological assessment, and the surgical
procedure.

Objective Stiffness and severe deformity pose a major challenge in total knee arthroplasty. Numerous techniques have been described
to gain exposure and improve knee flexion. Tibial tubercle osteotomy provides excellent and safe exposure of the joint, although
mechanical and wound complications have been reported.
Materials and methods We present a series of 32 consecutive complex primary total replacements where an osteotomy of the tibial tubercle was utilised.
Results The patients had a mean follow-up of 2 years and 11 months. Following the procedure, with the exception of one case complicated
with deep infection, all of the patients had improved clinically. The mean postoperative range of motion had increased to
102° (give P value < 0.005) and there were no cases of delayed union or non-union. A mechanical complication related to technique occurred
in one patient; there were no other cases with a postoperative extension lag.
Conclusion In this challenging population group, we have found a tibial tubercle tuberosity osteotomy to greatly facilitate exposure
without compromising the clinical and radiographic outcome. 相似文献

Assessment of possible low-wear with some former metal-on-metal (MoM) total hip arthroplasties (THA) led to the reintroduction
of metallic bearings in the late 80’s. The author reports on two studies of Metasul-28 mm cementless THA. In the first one
in a general population, impingement has been the main cause of osteolysis and Co level survey has been a good indicator of
Metasul bearing behaviour. In the second study, in a group of 83 less than 50-year-old and active patients, Metasul bearings
showed good wear resistance at 7.2 years mean follow-up. In both studies, no general toxic effect could have been detected
thus far. According to the current knowledge, it is always reasonable to expect low-wear and better THA longevity with use
of MoM bearings under the following conditions: 1) use of a CoCr alloy with high carbide concentration; 2) reduce impingement
risk (head without sleeve, slimmer as possible neck, perfectly adapted Morse cone from the same manufacturer, well — oriented
components); and 3) prefer cementless acetabular fixation. 相似文献
