Deep vein thrombosis of the lower limbs in Duhok: a descriptive study using Doppler ultrasound

Deep vein thrombosis [DVT] is a major medical problem, used to be assessed clinically and diagnosed by venography with all its hazards. Doppler Ultrasound [US] has replaced venography as the method of choice in diagnosis DVT of the lower limbs. This study was carried out to describe DVT cases detected by Doppler US among patients clinically suspected of having DVT. One hundred and sixty-two patients [86 males and 76 females] with clinically suspected DVT, referred to the Department of Radiology in Azadi Hospital in Duhok, were involved in this study. Color Doppler US was done for all patients in a systematic way, mapping all lower limb veins. DVT was found in 64 [38.1%] patients out of the 162 patients examined. Their ages ranged from 19-90 years, with the commonest age group affected being the 30-49 [43.7%] year age group. Popliteal vein was the commonest site affected [32.81%], followed by the posterior tibial vein [26.56%], perforators of varicose vein [25%], femoral vein [15.62%]. Color Doppler is a reliable method of diagnosis of DVT in symptomatic patients. The color Doppler has become the first line in investigation of DVT in many centers as it provides a non-invasive method of investigation. The technique has some limitations in patients with obesity, pregnancy or swollen edematous legs

Trombosis venosa del sistema yúgulosubclavio inducida por catéteres: su estudio con ecografía Doppler duplex pulsado / Doppler US deep venous thrombosis of the jugular and subclavian veins induced by catheters

En los últimos años el adelanto experimentado en el manejo y tratamiento de pacientes en situación crítica y condición grave, internados en salas de Terapia Intensiva o de Cuidados Críticos, llevaron a la necesidad de utilizar catéteres centrales, canalizaciones, etc. para efectuar el tratamiento por vía endovenosa adecuado. Todos ellos utilizan habitualmente como vía de acceso a la vena subclavia y en otras oportunidades la yugular. La cateterización de dichas venas llevan a la trombosis en el 28% de los casos y al tromboembolia pulmonar (TEP) en el 12%. Se presentan 9 casos de trombosis venosa profunda (TVP) del sistema yúgulosubclavio inducida por la colocación de catéteres: 6 casos de TVP de la vena subclavia y 3 casos de la vena yugular. Se describen los signos ecográficos característicos de TVP y en especial se remarca el signo de la "ausencia del batido de la válvula venosa" y el cut off sing (pérdida de los límites de la vasculatura normal con pobre definición del trombo) descriptos por Wiessleder para trombosis de la vena yugular interna

Complicaçöes da flebografia dinâmica profunda dos membros inferiores / Complications of deep dynamic phlebography of the legs

Foram avaliadas as complicaçöes da flebografia dinâmica profunda realizada em 40 membros de 29 pacientes portadores de varizes recidivadas de membros inferiores. Nos 16 casos em que foi empregado contraste com metrizoato de meglumina e cálcio, as complicaçöes imediatas observadas foram: dor do tipo queimaçäo durante a injeçäo em quatro pacientes (13,8%) e náuseas e vômitos em um (3,4%). Houve reaçäo alérgica em um (3,4%) entre 13 que receberam ioxaglato de meglumina e sódio. Näo houve nenhuma complicaçäo tardia. A flebografia dinâmica profunda continua a ser um exame de grande valor no estudo das doenças venosas
