[Deep venous thrombosis of the upper limb in a violin player: The "bow syndrome"]

Results of a Flexible Patient-Centered Approach to the Timing of Thoracic Outlet Decompression in Paget Schroetter Syndrome

BACKGROUND

Treatment algorithms for subclavian vein (SCV) effort thrombosis (Paget-Schroetter syndrome- PSS) are multiple, ranging from thrombolysis (TL) with immediate or delayed thoracic outlet decompression (TOD) to conservative treatment with anticoagulation alone. We follow a regimen of TL/pharmacomechanical thrombectomy (PMT) followed by TOD with first rib resection, scalenectomy, venolysis, and selective venoplasty (open or endovascular) performed electively at a time convenient for the patient. Oral anticoagulants are prescribed for 3 months or longer based upon response. The aim of this study was to evaluate outcomes of this flexible protocol.

METHODS

Clinical and procedural details of consecutive patients treated for PSS from January 2001 to August 2016 were retrospectively reviewed. Endpoints included success of TL and eventual clinical outcome. Patients were divided into 2 groups-Group I: TL/PMT + TOD; Group II: medical management/anticoagulation + TOD.

RESULTS

PSS was diagnosed in 114 patients; 104 (62 female, mean age 31 years) who underwent TOD were included in the study. Group I: 53 patients underwent TOD after initial TL/PMT (23 at our institution and 30 elsewhere) with success (acute thrombus resolution) in 80% (n = 20) and 72% (n = 24) respectively. Adjunctive balloon-catheter venoplasty was performed in 67%. TL failed to recanalize the occluded SCV in 11% (n = 6). Complete thrombus resolution was seen in 9% (n = 5). Residual chronic thrombus in 79% (n = 42) resulted in median SCV stenosis of 50% (range 10% to 80%). With continued anticoagulation, further thrombus retraction was noted with median 40% improvement in stenosis including in veins with unsuccessful TL. TOD was performed at a median of 1.5 months (range 2-8 months). Rethrombosis of the SCV occurred in 3 patients 1-3 days postoperatively and was managed with MT/SCV stenting/balloon angioplasty and anticoagulation. Symptomatic relief was achieved in 49/53 (92%) patients at a median follow-up of 14 months. Group II: 51 patients underwent TOD following medical treatment elsewhere with anticoagulation alone for an average 6 months (range 2-18 months) with recurrent SCV thrombosis in 5 (11%). Thirty-nine patients (76%) had persistent symptoms; the remaining had asymptomatic compression of the SCV with maneuvers. SCV occlusion persisted in 4 patients (7%); the indication for TOD being residual symptoms from compression of collateral veins, the median residual stenosis was 70% (range 30-90%). TOD was performed at a median of 6 months after diagnosis of PSS. Open venous reconstruction with endovenectomy and patch was performed in 4 patients and stenting in 2. Symptomatic relief was achieved in 46/51 (90%) at a median follow-up of 24 months.

CONCLUSIONS

For Paget Schroetter syndrome a management protocol encompassing elective thoracic outlet decompression at a convenient time following thrombolysis is safe and effective, with low risk of rethrombosis. Continued anticoagulation in the interim results in further recanalization of the subclavian vein and may reduce the need for open venous reconstruction.

Paget-Schroetter syndrome from manual handling at work: Case report and review of the literature

Paget-Schroetter syndrome (PSS) is a primary deep venous thrombosis of the subclavian-axillary vein complex occurring after repetitive and strenuous use of the shoulders and arms. Here, we report the case of a 24-year-old man who presented with left subclavian and axillary vein thrombosis after loading and unloading labor, who was diagnosed with PSS confirmed with Doppler ultrasound, and treated with anticoagulation. By comparing our case with 45 published case reports, we also aim to analyze patient characteristics, diagnostic methods, and treatment options for the disorder.

Two Patients with Paget-Schroetter Syndrome That Were Successfully Diagnosed by Doppler Ultrasonography: Case Studies with a Literature Review

We herein report on two male patients (age, 22 and 44 years) who were referred to our department with swelling of the upper right arm after attending other hospitals. Right subclavian vein thrombosis was demonstrated by ultrasonography and they were then further evaluated by contrast-enhanced computed tomography (CT). Successful treatment involved venous thrombectomy in one patient and anticoagulant therapy in the other. Paget-Schhroetter syndrome was confirmed using standard vascular ultrasonography. Despite the accuracy of this method for diagnosing Paget-Schroetter syndrome, some cases are difficult to confirm. We reviewed 29 previously published case reports of Paget-Schroetter syndrome and analyzed the patient baseline characteristics, time to diagnosis, and the diagnostic methods used.

Paget-Schroetter syndrome as a result of 1st rib stress fracture due to gym activity presenting with Urschel's sign - A case report and review of literature

BACKGROUND

Paget-Schrotter Syndrome (PSS) also known as "effort thrombosis" is a form of primary thrombosis in the subclavian vein at the costoclavicular junction is usually seen in younger patients after repeated strenuous activity of the shoulders and arms. When occurring in younger patients, PSS presents itself with predisposing factors such as unilateral dull, aching pain in the shoulder or axilla and swelling of the arm and hand.

CASE PRESENTATION

We report a rare case of unusual left axillo-subclavian vein thrombosis following narrowing of thoracic outlet due to stress injury of rib fracture likely during gym activity in absence of other clear risk factors and a negative hypercoagulable workup in a 27-year-old man who was admitted as left deltoid rupture 5 days after his usual gym. Subsequently he was transferred under vascular surgery for thrombectomy.

CONCLUSION

In addition to the unusual location in the left upper extremity in our case, the absence of common etiologic factors makes our case of Paget-Schroetter Syndrome a very unique one. This case report aims to discuss the common causes of PSS in order to raise a high index of suspicion in certain groups of patients. This will allow early identification and avoidance of catastrophic outcomes such as pulmonary embolism and stroke.

[Skin and mucosal diseases in musicians]

Whether they are professional or amateur, musicians are exposed to a various number of complications in relation to their practice, including cutaneous ones. The latter are often a simple musical stigma and a reason for pride for the musician. If they are symptomatic and disturb the musician, they have to be treated and prevented. We reviewed here those occupational and peculiar lesions that are often not that well known to the dermatologist.
