Post-thrombotic syndrome, functional disability and quality of life after upper extremity deep venous thrombosis in adults.

The post-thrombotic syndrome (PTS) after upper extremity deep venous thrombosis (UEDVT) has not been well characterized. The objective of our study was to describe and quantify residual symptoms, functional disability and quality of life associated with PTS after UEDVT in adults. Twenty-four patients with objectively diagnosed UEDVT (bilateral in 1 patient) at least 6 months previously were recruited from two Canadian thrombosis clinics. Data were collected on demographic characteristics, DVT risk factors and affected venous segments. The Villalta PTS scale, modified for the upper extremity, was used to diagnose PTS. Patients completed questionnaires on degree of functional disability (DASH questionnaire), and generic (SF-36) and disease-specific (VEINES-QOL) quality of life. Results were compared in patients with and without PTS. Patients were assessed a median of 13 months after the diagnosis of UEDVT. Daily ipsilateral arm or hand swelling was reported by 52% of patients and daily ipsilateral arm pain by 20% of study patients, compared with 0% and 0%, respectively, in the contralateral arm. PTS was present in 11/25 (44%) limbs (11/24 patients). One patient had severe PTS. Patients with PTS, compared with those without PTS, had significantly more functional disability (mean DASH score 20.9 vs. 3.7, p=0.009) and poorer quality of life (mean VEINES-QOL score 45.6 vs. 53.6; p=0.001; mean SF-36 Physical Component Score (PCS) 40.8 vs. 50.2; p=0.12). PTS scores were higher and quality of life was poorer when PTS involved the dominant arm. In conclusion, PTS occurs frequently after UEDVT and is associated with significant functional disability and reduced quality of life. Patients with dominant arm PTS appear to fare worse than those with non-dominant arm PTS. Larger, prospective studies to identify prognostic factors that lead to PTS after UEDVT are warranted.

The impact of venous thrombosis on quality of life.

Quality of life (QOL) is increasingly seen as an important outcome in clinical care. Etiology, diagnosis, and management of venous thrombosis have been studied extensively, but only few studies have examined the impact of venous thrombosis on quality of life. The purpose of this study was to examine the impact of venous thrombosis on quality of life in a well-defined population of patients with venous thrombosis, by using both a generic and a disease-specific quality of life measure. A total of 45 patients from the thrombosis clinic of the University of Vermont in Burlington, VT, returned a mailed questionnaire including the Short-Form 36 (SF-36) and a disease-specific venous thrombosis-quality of life (VT-QOL) questionnaire about the problems faced by patients with venous thrombosis. The sample consisted of 13 men (28.9%) and 32 women (71.1%). The mean age was 44.1 years, with a range from 21 to 80 years. Compared with population norms of a general U.S. population that were adjusted for age and sex (N= 2463), venous thrombosis patients scored significantly lower (p < 0.05) on all subscales of the SF-36. Patients with the postthrombotic syndrome (PTS) appeared to have more impairment in their quality of life as measured by both the SF-36 and the disease-specific questionnaire. All correlations between the SF-36 subscales and the subscales of the VT-QOL were significant, most of them on a p < 0.01 level. Given the impact of venous thrombosis and the postthrombotic syndrome on quality of life, assessment of QOL should be included in future studies on the outcome of venous thrombosis.

Automated computer interviews to elicit utilities: potential applications in the treatment of deep venous thrombosis.

OBJECTIVE: To assess the practicality of an automated computer interview as a method to assess preferences for use in decision making. To assess preferences for outcomes of deep vein thrombosis (DVT) and its treatment. STUDY DESIGN: A multimedia program was developed to train subjects in the use of different preference assessment methods, presented descriptions of mild post-thrombotic syndrome (PTS), severe PTS and stroke and elicited subject preferences for these health states. This instrument was used to measure preferences in 30 community volunteers and 30 internal medicine physicians. We then assessed the validity of subject responses and calculated the number of quality-adjusted life years (QALYs) for each individual for each alternative. RESULTS: All subjects completed the computerized survey instrument without assistance. Subjects generally responded positively to the program, with volunteers and physicians reporting similar preferences. Approximately 26.5% of volunteers and physicians had preferences that would be consistent with the use of thrombolysis. Individualization of therapy would lead to the most QALYs. CONCLUSIONS: Utilization of computerized survey instruments to elicit patient preferences appears to be a practical and valid approach to individualize therapy. Application of this method suggests that there may be many patients with DVT for whom treatment with a thrombolytic drug would be optimal.

[Artificial edema of the extremity]. / Zum Problem des artefiziellen Extremitätenödems.

Our report describes a 46-year-old woman with self-inflicted oedema of the left leg and the left arm. She induced leg oedema by an elastic bandage tourniquet and arm oedema by holding her arm dependent and immobile. A preexisting disorder of the affected leg (postthrombotic syndrome) and of the affected arm (hypoesthesia subsequent to surgical injury of the plexus brachialis) delayed the diagnostic proceedings. Our case report shows that: Confirmed presence of organic disease does not exclude limb oedema of self-inflicted origin. Oedema resulting from a tourniquet and "hysterical oedema" can be developed by one and the same patient. Effective care of such patients is only possible if dermatologist and psychiatrist work together all the time (liaison psychiatry).
