Management of traumatic superficial palmar arch pseudoaneurysm: a therapeutic challenge.

Pseudoaneurysm of the palmar arch is a rare entity. Diagnosis is dependent on high clinical suspicion. We present a case referred to the emergency department, with a history of glass penetrating trauma to the palmar surface with a pulsatile mass and jet bleeding. Doppler ultrasound evidenced a partially thrombosed pseudoaneurysm. A CT angiography examination showed a saccular formation arising from the superficial palmar arch. A conventional surgical approach was indicated. A clinical suspicion must be ventured to arrive at the correct diagnosis. Imaging modalities are needed to identify the pseudoaneurysm and plan the treatment course. Nonetheless, the sequence of diagnosis is individual, because further evaluation with different imaging methods may not change the rationale for the intervention. In our experience, conventional surgical removal is preferable, due to its safety and well-established outcomes.

Apresentamos o caso de um paciente encaminhado ao pronto-socorro com história de traumatismo penetrante por vidro na face palmar, com massa pulsátil e sangramento em jato. A ultrassonografia com Doppler evidenciou pseudoaneurisma parcialmente trombosado, e a angiotomografia demonstrou formação sacular originada do arco palmar superficial. Uma abordagem cirúrgica convencional foi indicada. Para prosseguir com o diagnóstico correto, essa suspeita clínica deve ser aventada.

Association between the degree of iliac venous outflow obstruction by intravascular ultrasound and lower limb venous reflux.

OBJECTIVE: The present study aims to evaluate the association between the degree of iliac venous outflow obstruction (IVOO) identified by intravascular ultrasound (IVUS) and venous reflux presentation in the lower limbs on duplex ultrasound (DU). METHODS: Patients with bilateral chronic venous insufficiency, CEAP (clinical-etiology-anatomy-pathophysiology) C3 to C6, and a visual analog scale score for pain >5 underwent DU for reflux evaluation of the deep venous system (reflux ≥1 second); superficial system, great saphenous vein, and small saphenous vein (reflux ≥0.5 second); and perforator system (reflux ≥0.35 second). All patients underwent IVUS in the iliac venous territory. The area of the impaired venous segments was categorized as obstruction <50% (category 1), 50% to 79% (category 2), and ≥80% (category 3). The venous clinical severity score and reflux multisegment score (RMS) were assessed. RESULTS: A total of 51 patients (n = 102 limbs; age, 50.53 ± 14.5 years; 6 men) were included. The predominant clinical severity CEAP class was C3 in 54 of 102 limbs (52.9%). The mean VCSS was 14.3 ± 6.7. A severe RMS (≥3) was registered in 63.4% of the limbs. Of the 102 limbs, 51 (50%) presented with category 1, 27 (26.5%) with category 2, and 24 (23.5%) with category 3. Previous deep vein thrombosis (DVT) was associated with critical obstruction (odds ratio [OR], 3.65; 95% confidence interval [CI], 1.29-10.38; P = .015). The superficial and perforator venous systems had no association with the degree of IVOO. Deep venous reflux (DVR) had a significant association with significant IVOO (obstruction ≥50%; OR, 6.44; 95% CI, 2.19-18.93; P = .001) and critical IVOO (obstruction ≥80%; OR, 4.57; 95% CI, 1.70-12.27; P = .003) and a significant linear association with the IVOO degree and reflux in the femoral veins (P < .001) and popliteal vein (P = .008). Significant lesions were significantly more likely to develop in the left limb (OR, 5.76; 95% CI, 2.46-13.50; P < .001). After multivariate analysis, DVR remained a predictor for significant and critical obstruction (P < .003 and P < .012, respectively). Left limb and previous DVT remained as predictors for IVOO of ≥50% and ≥80% (P < .001 and P = .043, respectively). CONCLUSIONS: We found a significant linear association between the degree of IVOO and reflux in the deep venous system on DU. Limbs with DVR, a severe RMS, loss of respiratory variation on DU, and previous DVT were more likely to be affected by IVOO of ≥50%, especially with left leg involvement.

Association between the degree of iliac venous outflow obstruction by intravascular ultrasound and lower limbs venous reflux

OBJECTIVE: This study aims to evaluate the association between the degree of iliac venous outflow obstruction (IVOO) identified by Intravascular Ultrasound (IVUS) and venous reflux presentation in lower limbs on Duplex Ultrasound (DU). METHODS: Patients with bilateral chronic venous insufficiency, CEAP C3-6 (Clinical-Etiology-Anatomy-Pathophysiology classification), and with Visual Analogic Scale score for pain > 5, underwent DU for reflux evaluation: deep venous system (reflux ≥ 1 s); superficial system, great saphenous vein (GSV) and small saphenous vein (SSV) (reflux ≥ 0.5 s); perforator system (reflux ≥ 0.35s). All patients underwent IVUS in the iliac venous territory. The area of the impaired venous segments was categorized as obstructions< 50% (Cat. 1); 50-79% (Cat. 2), and ≥ 80% (Cat. 3). Venous clinical severity scale (VCSS) and reflux multisegment score (RMS) were assessed. RESULTS: 51 patients (n=102 limbs; 50.53 ± 14.5 years, 6 men) were included. The predominant clinical severity CEAP class was C3 in 54/102 (52.9%) limbs. VCSS mean was 14.3 ± 6.7. Severe RMS (≥ 3) was registered in 63,4% of the limbs. In 51/102 limbs (50%) presented cat. 1, 27/102 (26.5%) cat. 2, and 24/102 (23.5%) cat. 3. Previous DVT was associated with critical obstruction (OR 3.65; 95% CI: 1.29-10.38; p=0.015). Superficial and perforator venous systems had no association with the degree of iliac obstruction. Deep venous reflux (DVR) had a significant association with significative IVOO (obstruction ≥ 50%) (OR 6.44; 95% CI: 2.19-18.93; p=0.001) and critical IVOO (obstruction ≥ 80%) (OR 4.57; 95% CI: 1.70-12.27; p=0.003), and significant linear association with IVOO degree and reflux in femoral veins (p<0.001) and popliteal vein (p=0.008). Significant lesions had 5.76 (95% CI: 2.46-13.50; p<0.001) more odds of happening in the left limb. After a multivariate analysis, DVR remained as predictor for significant and critical obstruction (p<0.003, p< 0.012; respectively). Left limb and previous DVT remained as predictors for IVOO ≥50% and IVOO≥ 80% (p<0.001, p=0.043; respectively) CONCLUSIONS: There is a significant linear association between the degree of iliac venous outflow obstruction and reflux in the deep venous system on DU. Limbs with DVR, severe RMS, loss of respiratory variation on DU, and previous DVT, were more likely to be affected by IVOO ≥ 50%, especially with the left leg involvement.

Endovascular treatment of aortic saccular aneurysms associated with Adamantiades-Behçet disease.

Adamantiades-Behçet disease is a multisystemic disorder that classically presents with oral and genital ulcers and ocular involvement, with vascular involvement in up to 38% of cases. Aortic involvement is one of the most serious manifestations and is associated with high mortality rates, occurring in 1.5 to 2.7% of cases. We report a case of a saccular abdominal aorta aneurysm in a 49-year-old male patient with complicated Adamantiades-Behçet disease that was treated with endovascular repair.

Remodeling technique using T-stenting and coils to treat complex renal aneurysm.

Renal artery aneurysm is a rare condition that is being diagnosed with increasing frequency because of wider use of angiotomography. We describe a case of complex type II renal artery aneurysm in a patient with systemic arterial hypertension and non-dialysis chronic kidney disease. The treatment performed was endovascular repair using the remodeling technique with T-stenting and coils to preserve the renal arterial branches, obtaining satisfactory arteriographic results and good clinical outcomes.
