Establishment of a nomogram model for predicting therapy complications in patients with polycythemia and deep venous thrombosis

BACKGROUND Patients with deep venous thrombosis(DVT)residing at high altitudes can only rely on anticoagulation therapy,missing the optimal window for surgery or thrombolysis.Concurrently,under these conditions,patient outcomes can be easily complicated by high-altitude polycythemia(HAPC),which increases the difficulty of treatment and the risk of recurrent thrombosis.To prevent reaching this point,effective screening and targeted interventions are crucial.Thus,this study analyzes and provides a reference for the clinical prediction of thrombosis recurrence in patients with lower-extremity DVT combined with HAPC.AIM To apply the nomogram model in the evaluation of complications in patients with HAPC and DVT who underwent anticoagulation therapy.METHODS A total of 123 patients with HAPC complicated by lower-extremity DVT were followed up for 6-12 months and divided into recurrence and non-recurrence groups according to whether they experienced recurrence of lower-extremity DVT.Clinical data and laboratory indices were compared between the groups to determine the influencing factors of thrombosis recurrence in patients with lowerextremity DVT and HAPC.This study aimed to establish and verify the value of a nomogram model for predicting the risk of thrombus recurrence.RESULTS Logistic regression analysis showed that age,immobilization during follow-up,medication compliance,compliance with wearing elastic stockings,and peripheral blood D-dimer and fibrin degradation product levels were indepen-dent risk factors for thrombosis recurrence in patients with HAPC complicated by DVT.A Hosmer-Lemeshow goodness-of-fit test demonstrated that the nomogram model established based on the results of multivariate logistic regression analysis was effective in predicting the risk of thrombosis recurrence in patients with lowerextremity DVT complicated by HAPC(χ^(2)=0.873;P>0.05).The consistency index of the model was 0.802(95%CI:0.799-0.997),indicating its good accuracy and discrimination.CONCLUSION The column chart model for the personalized prediction of thrombotic recurrence risk has good application value in predicting thrombotic recurrence in patients with lower-limb DVT combined with HAPC after discharge.

Deep Venous Thrombosis: Commonly Affected Veins in the Lower Limbs

Aim and Objectives: This study aimed to record the commonly affected veins in the lower limbs, to compare the affected sides and gender and to correlate the Doppler findings and stages of deep venous thrombosis (DVT). Materials and Methods: A descriptive retrospective study of 46 already diagnosed cases of lower limb DVT. Results: Out of 46 cases of DVT, 71.74% were females. The majority of patients (93.47%) were affected in unilateral lower limb with significant predominance (65.22%) to affect the left lower limb (p Conclusion: Lower limb deep venous thrombosis affects left lower limb more than right and females more than males. Superficial femoral vein (SFV) and common femoral vein (CFV) are the most common affected veins. Lower limb DVT predominantly present in acute stage with venous distension and absent blood flow.

Combined effect of Traditional Chinese Medicine decoction and low-molecular-weight heparin calcium on the postoperative deep venous thrombosis in patients with lower limb fracture

OBJECTIVE: To investigate the combined effect of Traditional Chinese Medicine(TCM) decoction and low-molecular-weight heparin calcium on deep vein thrombosis(DVT) induced by surgery in patients with lower limb fracture.METHODS: Totally 86 hospitalized patients with DVT after surgery of lower limb fracture between September 2012 and January 2015 were recruited and randomly divided into control group and observation group, 43 cases in each group. The patients in the control group were treated with subcutaneous injection of low-molecular-weight heparin calcium, and those in the observation group were additionally given Danshen Injection and TCM decoction. The differences between two groups in occurrence rate, medication time, therapeutic effects,recurrence rate of thrombosis, activated partial thromboplastin time(APTT), and prothrombin time(PT) were compared.RESULTS: The occurrence rate of DVT in observation group(4.65%, 2/43) was lower than that in control group(27.91%,12/43)(P<0.05). The medication time of observation group was(6.15±2.94) d, shorter than(9.76±3.12) d in the control group(P<0.05). In observation group, 2 cases of DVT were cured(2/2); in the control group, 9 cases presented therapeutic effects and the total effective rate was 75.00%(9/12). The improvement of APTT and PT in the observation group was better than that in the control group(P<0.05).CONCLUSION: Integrative TCM decoction plus low-molecularweight heparin calcium is superior to applicaton of low-molecularweight heparin calcium alone in reducing and treating DVT in the postoperative patients with lower limb fracture.

Deep Vein Thrombosis of the Upper Limb: About 6 Cases Collected in Dakar

Deep vein thrombosis of the upper limb is a rare location of venous thromboembolic disease. Data on this form of thrombosis are limited. We report six cases collected in Dakar. The sex ratio was 0.5 and the average age was 27.6 years with extremes of 17 and 39. Painful limb edema was the most constant sign and involved the non-dominant limb in almost all patients. Thrombosis occurred in a field of peripartum cardiomyopathy in two patients and SS sickle cell disease in one patient taking oral contraception. There was neither cancer nor venous catheter in medical history. The diagnosis was made by venous Doppler ultrasound in all patients. Subclavian involvement was the most common. The thrombophilia assessment, done for two patients, was normal. It was about exertion thrombosis on three (3) patients. All the patients had received antivitamin K treatment relaying a low molecular weight heparin. Venous limb compression was associated with anticoagulation for all patients. The treatment duration was six (6) months. There were no reports of pulmonary embolism or death. One patient presented a post-thrombotic syndrome.

Pitfalls and sources of error of color duplex ultrasonography in detecting deep vein thrombosis of proximal lower extremities

Purpose To analyze the sources of errors and discuss the techniques to eliminate pitfalls in detecting deep vein thrombosis (DVT) of the proximal lower extremities with color duplex ultrasonography (CDUS). Methods Sixty-eight cases with initial and repeat venous CDUS of the proximal lower extremities were retrospectively reviewed. The repeat was done within 24 hours after initial CDUS scanning. Comparing repeated images to initial ones, the pitfalls and sources of error in CDUS of the proximal lower extremities were discussed. Results In total 68 repeat studies, there were 62 results as same as initials and 4 cases of false negative DVT and 2 cases of false positive DVT. Conclusion Venous CDUS in detecting DVT is observer dependent. Some pitfalls and errors can be eliminated and corrected with proper scan techniques. CDUS is the most valuable imaging modality for assessing suspected DVT in the proximal lower extremities.

Ultrasound-Guided Superior Gluteal Nerve Hydrodissection in the Treatment of Deep Gluteal Syndrome

Background: Deep gluteal syndrome is a common cause of posterior hip pain. It results from peripheral nerves, such as the sciatic or superior gluteal nerve, being compressed in the deep gluteal space. Hydrodissection is a novel technique for the treatment of nerve pain due to entrapment. The use of hydrodissection for the treatment of deep gluteal syndrome has not been reported. Methods: A case report involved a 42-year-old female presenting with deep gluteal syndrome. Case report: We report, with patient consent, an ultrasound-guided superior gluteal nerve hydrodissection method used for treating the deep gluteal syndrome. A previously healthy 42-year-old female patient sought medical attention due to persistent left gluteal pain. Trials of joint injections, physiotherapy, and epidural blocks were unsuccessful. Hydrodissection under ultrasound-guidance allowed separation of the fascial plane in areas with significant neural innervation. We targeted the superior gluteal nerve with hydrodissection offering the patient immediate and persistent relief from her symptoms. Conclusion: Ultrasound-guided hydrodissection of the superior gluteal nerve offers an effective and novel diagnostic and treatment option for deep gluteal syndrome.

An Unwonted, Pedagogic Case Report on Effort Thrombosis of Right Brachial Vein

Deep vein thrombosis (DVT) is one or more blood clots formed inside the deep vein in the body resulting in complete or partial blockage of blood flow through the affected vein. Upper Extremity DVT (UEDVT) accounts for 5% - 10% of all cases of DVTs. Previously it was thought to be a rare disorder. However in recent years with the advent of various indwelling intravenous devices, hypercoagulable state like COVID-19, secondary UEDVT did not remain infrequent presentation anymore. Though primary UEDVT, also known as Effort Thrombosis, that takes place without any underlying obvious pathology is a rare form till now. We presented a case of 46 years female who presented to the emergency with complaints of progressively increasing pain (7 days) and swelling (3 days) of her right forearm since last 7 days following strenuous and heavy work by her dominant/ right hand during the period of festival. She initially ignored her condition because of the Durga Puja festival. As her symptoms deteriorated she eventually had to attend the emergency department. Eventually an urgent ultrasonography color Doppler was done on emergency basis which diagnosed underlying DVT of her right brachial vein. She was managed with low molecular weight heparin, urgent fasciotomy owning to her impending compartment syndrome. Other tests ruled out any secondary underlying pathology. She improved and discharged without any complications on oral anticoagulant. Exigent events in her history were trauma followed by fall on her right elbow 2 months back and then presenting signs & symptoms commencing at the same region following strenuous, tedious activities over 7 days and consequential effort thrombosis of her right brachial vein. All of that compelled us to ruminate on rare differentials of her presentation and eventually come to this rare diagnosis. The author hence brought this pedagogic case to the readers, especially emergency & primary care physicians and emphasised the importance of being intuitive about rare but deadly differentials which come from proficiency & experience in the field of medicine.
