ABSTRACT
Background The incidence and progression of glaucomatous optic neuropathy is related to a disturbance of the retrobulbar hemodynamics.Compound anisodine is clinically applied for the treatment of ischemic ocular diseases.Objective To evaluate the effects of compound anisodine injection on the ocular blood flow of glaucoma patients.Methods Twenty-one patients with primary glaucoma were divided into the treatment group and the control group.The eyes of each patient in the treatment group were selected further into the treatment eye group (11 eyes with greater mean deviation [MD]) or the opposite eye group(11 eyes with lesser MD).One of the eyes of each patient in the control group with MD value were selected as control eyes (10 eyes).The treatment eye group received compound anisodine on the para-superficial temporal artery via subcutaneous injection once a day for 2 treatment periods (each period equals 14 days,with 7 days intermittent between periods,totally 35 days) in addition to routine treatment.The retrobulbar blood flow,optic disc data,refraction error,visual field and intraocular pressure were measured in 3 time points:Before treatment period (baseline test),one day after treatment period (the 1st postreatment test) and 35 days after treatment period (the 2nd posttreatment test).Results Compared with the control group,the peak systolic velocity (PSV) and end diastolic velocity (EDV) of short posterior ciliary artery (SPCA) of the treatment eye group were relatively increased significantly in the 1st posttreatment test (P =0.017,0.028),the PSV of SPCA of the opposite eye group was relatively increased significantly in the 1 st posttreatment test (P =0.049),the EDV of central retinal artery (CRA) of the opposite eye group was relatively increased significantly in the 2nd posttreatment test (P =0.035).In contrast to the treatment eye group,the inferior quadrant RNFL thickness of the optic disc decreased significantly in the 2nd posttreatment test in the control group (P =0.009),the 6 o'clock RNFL thicknesses of the optic disc decreased significantly in the 1 st posttreatment test in the control group (P =0.014),and the 6 o'clock and 7 o'clock RNFL thicknesses of the optic disc decreased significantly in the 2nd posttreatment test in the control group (P =0.029,0.011).Conclusions The application of compound anisodine for the treatment of primary glaucoma relatively increases the PSV and EDV of SPCA.
ABSTRACT
Objective To observe the influence of heat-clearing and blood-activating traditional Chinese medicine sitz bath on postoperative wound healing of hemorrhoids Methods 100 cases of hemorrhoids surgery pa-tients were selected.According to random number table method,they were divided into the observation group and con-trol group,100 cases in each group.All of patients underwent hemorrhoids excision surgery,the control group was giv-en potassium permanganate sitz bath, the observation group was given heat-clearing and blood-activating traditional Chinese medicine sitz bath.The two groups were given compound carraghenates cream for external use after sitz bath. The postoperative wound healing time,degree of pain and clinical efficient of the two groups were observed and com-pared.Results In two groups before treatment,the pain scores were (4.06 ±1.34)point,(4.05 ±1.36)point,with no significantly different (t=0.63,P<0.05); compared with before treatment,the two groups after treatment the pain scores were (1.13 ±0.51)point,(2.72 ±0.74)point,the difference was statistically significant (t =3.72, 2.98,P<0.05);the pain scores after treatment in observation group was significantly lower than that of the control group,the difference was statistically significant (t=2.73,P<0.05).In observation group,the wound healing time was (13.23 ±4.27)d,which was shorter than (18.78 ±6.43)d of the control group,the difference was statistically significant (t=6.44,P<0.05).The clinical efficiency of the observation group was 98%,which was significantly higher than 86%of the control group,the difference was statistically significant (χ2 =4.89,P<0.05).Conclusion Heat-clearing and blood-activating traditional Chinese medicine sitz bath can promote the healing of postoperative wound of hemorrhoids,and can effectively reduce the degree of pain.
ABSTRACT
Objective To evaluate the basilar artery hemodynamical changes in cervical rotation and ventral flexion by color Doppler flow imaging(CDFI). Methods Basilar artery blood flow were detected during cervical With cervical right lateral,left lateral rotation and ventral flexion, the detection ratio of basilar artery by ultrasound were 89% ,84% ,81% respectively. There were no difference in statistics between the detction ratio of three kinds during cervical flexion,peak systolic velocity(PSV) and end-diastolic velocity(EDV) decreased apparently during left lateral rotation,which did not change during right lateral rotation. No changing was found with resistant index between the three kinds of cervical position. Conclusions The hemodynamic changing of basilar artery during cervical rotation and flexion could be detected by CDFI accurately,which might be useful in clinical study.
ABSTRACT
Objective To summarize the clinical application of the Tempofilter Ⅱ temporary caval filter.Methods The Tempofilter Ⅱ temporary caval filter was employed in 24 patients from April 2002 to August 2006.Before the implantation,we performed color ultrasonography to detect the extent of thrombus and the situation of inferior vena cava,renal vein,and access vein(right internal jugular vein).Under the guidance of color ultrasonography and X-ray fluoroscopy(free of contrast agent),the temporary filter was placed in the inferior vena cava distal of the renal vein orifice through a guide wire by using the Seldinger technique.Results The filter was successfully implanted and removed in all the 24 patients.The duration of placement was 5 days～6 weeks(mean,16.8 days).Filter thrombosis occurred in 4 patients at 3 days ～ 2 weeks after operation.The thrombi(
ABSTRACT
Objective To evaluate the feasibility and clinical value of color Doppler flow imaging(CDFI) guided inferior vena caval filter insertion(IVCFI). Methods Thirty-one consecutive patients with unilateral lower extremity deep venous thrombosis were selected for IVCFI. Screening CDFI was performed in all the patients. Locations of renal veins (RV),maximum diameter of the inferior vena cava (IVC),and presence or absence of thrombus were documented. If visualization was adequate,IVCFI was performed under guidance of CDFI. CDFI and abdominal plain film of radiograph were used to document proper deployment,and circumferential engagement of the filter struts in the IVC wall. Also,CDFI was repeated each one month to assess IVC filter migration,thrombus adherent to the filter,and IVC patency. Results CDFI visualization was adequate in thirty-one patients(100%) and the average diameter of IVC was 19.7 mm. Thirty-one VenaTech IVC filters were placed without technical difficulty. No technical complication occurred in all the patients. Follow-up examination showed that no filter uncompleted opening and migration and no IVC thrombus were observed. Seven cases (29%) with embolus trapped by IVC filter were found. There had been no report of pulmonary emboli after IVCFI. Conclusions Placement IVC filter is feasible and safe with CDFI. CDFI-guided IVCFI substantially reduces the procedural cost and avoids the need for radiation exposure and intravenous contrast.
ABSTRACT
ObjectiveTo evaluate inferior vena cava (IVC) filter placement guided by color ultrasonography for the prevention of pulmonary embolism(PE) in cases of deep veous thrombosis(DVT) of the lower extremity. Methods From May 2002 to July 2003, 30 DVT cases were admitted and treated by IVC filter placement under the guide of color ultrasound. Fifteen cases received open thrombectomy immediately after filter placement, others were treated conservatively.Results Filters were successfully placed in all patients without complications except for one case in which occlusion was found during follow up of 1～14 months. Four patients surviving previous PE attacks before the placement of a filter had no more PE attacks thereafter. Conclusions IVC filter placement guided by color ultrasonography can prevent PE due to DVT effectively.
ABSTRACT
Objective To report an improved method, color-ultrasonography-guided inferior vena cava (IVC) filter placement, for preventing the pulmonary embolism (PE) caused by the deep venous thrombosis (DVT). Methods Color-ultrasonography-guided IVC filter insertion was performed in 9 patients with DVT of lower limb, 1 of which also had PE accompanied with at the time of admission. Out of the 9 patients, 5 patients underwent embolectomy immediately after the filter placement while the other 4 patients were treated conservatively. Results The placements were all completed successfully. Follow-up observations for 1～7 months (mean 2 months) found no complications or occurrence of PE. No recurrence of PE was found in the patient already with PE. Conclusions The color-ultrasonography-guided IVC filter placement can effectively prevent PE caused by DVT. The method is suitable for severe, immovable patients, as well as patients with renal insufficiency and being allergic to intravenous contrast, and is safe, convenient, cheap and prone to popularization.
