Achilles tendon rupture is thought to be increasing with participation in sports activities. Both operative and non-operative treatments of Achilles tendon rupture include a period of immobilization. Complications following treatment of the Achilles tendon rupture include recurrence of rupture, flexor weakness, infection, and wound problems. However, deep vein thrombosis (DVT) after operative treatment of the Achilles tendon has not been reported. We report on a case of DVT after Achilles tendon repair.

From July 1988 to January 1991 six patients, aged 29 to 70 years underwent transfemoral thrombectomy for the treatment of deep vein thrombosis. Preoperative venograms showed thrombi in the following locations: calf veins[five], superficial femoral or popliteal veins [four], common femoral veins[three], and iliac veins[three], Durations of symptoms before admission were from 1 day to 20days. Operations were performed under local anesthesia and all the patients were requested for doing Valsalva maneuver during thrombectomies. All patients were received heparin pre-and postoperatively, which was switched to Coumadin for preventing of rethrombosis. One patient was transferred to other hospital 4 months after operation due to regional reason, and the remained five patients were evaluated with a mean follow-up time of 20 months. There was no evidence of postoperative pulmonary embolism. Three of five patients were clinically asymptomatic. One complained of the heaviness of involved leg in the evening, and the other had discomfort on walking Even though our cases were a few in number, we concluded that thrombectomy is a valuable treatment modality of deep vein thrombosis.

Mechanical valve thrombosis is a serious and potential lethal complication unless early diagnosis & prompt therapy are made. We have been experienced 3 cases of valve thrombosis. From Aug. 1988 to July 1994, reoperations of mitral valve replacement [MVR] with mechanical prostheses [all mitral] were performed in three patients[2 men, 1 woman] due to valve thromboses. All three patients were diagnosed by means of cineradiography. Preoperative status of was shock status and he was applied intra-aortic balloon pump [IABP]. All three cases of prosthetic valve failure [PVF] were treated by Redo-MVR. Time intervals of reoperations were 5months, 40months, and 35months, respectively. In all cases, valve thromboses were excised successfully. Cineradiography provided an accurate diagnosis in all cases, which was utilized as safe, reliable & noninvasive imaging modalities. There were no operative death & complication. All three patients were fully recovered and returned to their employements, and active lives.

Drones of honeybee (Apis mellifera) have been regarded as a useful value only when mating with queen bee. However, the drone pupae have been reported to be nutritionally valuable, and a potential beekeeping product. In this study, drone pupae extracted with 5% acetic acid were used to measure anti-thrombosis related fibrinolytic activity using Strup and Mullertz fibrin plate method. As a result, the drone pupae extract showed higher effect of fibrinolytic activity(clear zone diameter 20.83mm) compared to the human plasmin (clear zone diameter 12.93mm) used as a positive control. It was suggested that the extract of drone pupae can be developed as a functional material helping prevention or treatment of various vascular diseases.

Lower extremity deep vein thrombosis (DVT) is a serious medical condition that can result in local pain and gait disturbance. DVT progression can also lead to death or major disability as a result of pulmonary embolism, postthrombotic syndrome, or limb amputation. However, early thrombus removal can rapidly relieve symptoms and prevent disease progression. Various endovascular procedures have been developed in the recent years to treat DVT, and endovascular treatment has been established as one of the major therapeutic methods to treat lower extremity DVT. However, the treatment of lower extremity DVT varies according to the disease duration, location of affected vessels, and the presence of symptoms. This article reviews and discusses effective endovascular treatment methods for lower extremity DVT.

Objectives: This study examined the effects of 8 types of herbal prescriptions prescribed to alleviate dementia symptoms in a rat model of arterial thrombosis induced by ferric chloride ($FeCl_3$). Methods: Thirty minutes before 35% $FeCl_3$ treatment, SD rats were intraperitoneally injected with the 8 types of herbal prescriptions, respectively. We tested the effects of the herbal prescriptions on time to occlusion (TTO) in an arterial thrombosis model using a laser Doppler flow meter. In addition, thrombus weight (TW) and collagen fiber damages were evaluated in the same condition. Results: Herbal prescriptions showed the following rank-order based on their TTO: Chong-myung-tang (CMT) > modified Jangwonhan 02 (LMK02) > Toki-shakuyaku-san (TSS) ${\geq}$ Oren-gedoku-to (OGT) ${\geq}$ Yokukansan (YKS). In particular, CMT (100 mg/kg, i.p.) and LMK02 (100 mg/kg, i.p.) delayed the TTO the most ($14.83{\pm}0.98$ and $13.67{\pm}1.03$ min, respectively) compared with the vehicle group ($7.95{\pm}0.78$ min, P<0.001). In addition, CMT, LMK02, and OGT treatment ($0.63{\pm}0.01$, $0.66{\pm}0.02$ and $0.67{\pm}0.01$ mg/mm, respectively) significantly reduced thrombus weight compared with the vehicle treatment ($0.78{\pm}0.03$, P<0.001) and also alleviated collagen fiber damage (CMT; $28.40{\pm}2.22$%, LMK02; $30.79 {\pm} 4.07$%, OGT; $26.20{\pm}1.48$%) in the vessels injured by $FeCl_3$. Therefore, CMT and LMK02 showed the greatest preventive activity in rat model of arterial thrombosis induced by $FeCl_3$. Conclusions: These results provide experimental evidence for traditional use of herbal prescriptions, suggesting that CMT and LMK02 extracts could be used to prevent vascular injury and thrombosis in the early stages of dementia.

Objectives: The aim of this study was to examine the antithrombotic effects of the four herbal ingredients (Mume Fructus, MF; Santali Albi Lignum, SAL; Amomi Tsao-Ko Fructus, ATF; and Amomi Fructus, AF) of modified Jeho-tang (MJHT) in a ferric chloride ($FeCl_3$)-induced carotid arterial thrombosis model. Methods: Thirty minutes prior to a 35% $FeCl_3$ application, Sprague-Dawley (SD) rats were injected with saline, MF, SAL, ATF or AF (100 mg/kg, intraperitoneal injection), respectively. The effect of the MJHT ingredients was examined for time to occlusion (TTO) and thrombus weight (TW) in a $FeCl_3$-induced thrombosis model. Histological analysis was performed to examine the effect of the MJHT ingredients on collagen fiber damage using hematoxylin & eosin and Masson's trichrome staining. Results: Compared with vehicle treatment, MF, SAL and ATF treatment delayed TTO (vehicle, $8.11{\pm}0.60$ min; MF, $16.67{\pm}1.03$ min; SAL, $17.50{\pm}1.52$ min and ATF, $13.33{\pm}1.21$ min; P < 0.001) and inhibited thrombus formation (vehicle, $0.79{\pm}0.03$ mg/mm; MF, $0.61{\pm}0.07$ mg/mm; SAL, $0.57{\pm}0.03$ mg/mm and ATF, $0.72{\pm}0.02$ mg/mm; P < 0.001). In addition, each herbal ingredient of MJHT except for AF prevented the collagen fiber damage induced by a 35% $FeCl_3$ application. These results indicate that the MJHT ingredients MF ${\geq}$ SAL ${\geq}$ ATF ${\geq}$ AF possess antithrombotic activity in a $FeCl_3$-induced carotid arterial thrombosis. Conclusions: Altogether, these results are the first evidence that the MJHT ingredients MF, SAL and ATF have the ability to prevent vascular damage and thrombus formation in $FeCl_3$-induced carotid arterial thrombosis.

Thrombosis in valve or left atrium after mechanical mitral valve replacement causes prosthetic valve dysfunction or thromboembolism. Early and adequate therapy is very important but clinically not easy. Thrombolysis can avoid reoperation-related risks and act as an optimal therapy for prosthetic valve thrombosis. This report describes three patients who were treated by using low molecular weight heparin (LMWH) and wafarin. Two patients, including one pregnant woman, had prosthetic valve thrombosis and immobility of valve leaflets, and one patient with recent cerebral infarction due to thromboembolism had thrombus in left atrium. Fraxiparine 0.3 cc (7,500 ICU AXa) was administrated subcutaneously twice or triple daily. At discharge, thrombosis in valve and left atrium were completely or near totally lysed and valve leaflets were normally mobile. During the period of thrombolysis and follow up, there were no complications in all patients.

Mechanical valve is one of the most widely used implantable artificial organs of which the reliability is so important that its failure means the death of patient. Therefore early noninvasive detection is essentially required, though mechanical valve failure with thrombosis is the most common. The objective of this paper is to detect the thrombosis formation by spectral analysis and neural network. Using microphone and amplifier, we measured the sound from the mechanical valve which is attached to the pneumatic ventricular assist device. The sound was sampled by A/D converter(DaqBook 100) and the periodogram is the main algorithm for obtaining spectrum. We made the thrombosis models using pellethane and silicon and they are thrombosis model on the valvular disk, around the sewing ring and fibrous tissue growth across the orifice of valve. The performance of the measurment system was tested firstly using 1 KHz sinusoidal wave. The measurement system detected well 1KHz spectrum as expected. The spectrum of normal and 5 kinds of thrombotic valve were obtained and primary and secondary peak appeared in each spectrum waveform. We find that the secondary peak changes according to the thrombosis model. So to distinguish the secondary peak of normal and thrombotic valve quantatively, 3 layer back propagation neural network, which contains 7, 000 input node, 20 hidden layer and 1 output was employed The trained neural network can distinguish normal and valve with more than 90% probability. As a conclusion, the noninvasive monitoring of implanted mechanical valve is possible by analysing the acoustical spectrum using neural network algorithm and this method will be applied to the performance evaluation of other implantable artificial organs.
