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.展开更多

Methods: 70 patients were divided into two groups according to the presence or absence of percutaneous transluminal angioplasty and stenting. Results: The mean circumferential diameter difference between the affected limbs and the healthy limbs and the knees at 15 cm was statistically significant. The cure rate and effective rate of the research group were higher than those of the control group (P<0.05). Conclusion: Percutaneous transluminal angioplasty and stenting are of high value in acute lower extremity deep venous thrombosis.展开更多

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.展开更多

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.展开更多
