Testicular Pain as A Warning Symptom of a Symptomatic Abdominal Aortic Aneurysm: Case Report and Review of The Literature.

BACKGROUND: Isolated testicular pain is an unusual clinical presentation of symptomatic abdominal aortic aneurysms (AAA). We present two patients hemodynamically stable with an isolated acute testicular pain related to an AAA and a review of the published literature up to present. METHODS: Two adult-old males with an acute isolated testicular pain presented to the emergency department. Although both cases had their symptoms for more than 24 hours and were hemodynamically stable, the misdiagnosis of a urological condition in one case and a delay of the intervention in the second resulted in a sudden drop of vital signs and the need of an urgent open surgery. RESULTS: A bibliographic review of the 15 published cases is presented. Most cases occurred without a previous diagnosis of AAA. Aneurysms were characteristically very large (mean 10 cm). The initial diagnosis was frequently wrong, attributing the pain mostly to genito-urinary conditions. The testicular pain presented days and even weeks before rupture, which may offer a convenient window of hemodynamic stability for repair. CONCLUSIONS: Acute testicular pain in adult-old patients with aneurysm risk factors and specially with a first urological evaluation discarding a genitourinary disorder should alert clinicians to consider the diagnosis of a symptomatic abdominal aortic aneurysm. The early and accurate recognition of these cases may increase the survival.

Changing trends in inferior vena cava filter indication for venous thromboembolism over the last two decades: a retrospective observational study.

BACKGROUND: The present study aimed to evaluate changes in the incidence, patients' profile and indications of inferior vena cava filters at a single center over the past two decades. METHODS: We retrospectively analyzed 187 consecutive patients with a venous thromboembolism requiring a filter at a tertiary hospital between 1999-2018. Within this period the availability of retrievable filters (since 2007) and the withdrawal of filter indication for recurrent venous thromboembolism from guidelines (since 2008) may have contributed to change practice patterns. Patients' profile, filter indication and survival were compared between decades (1999-2008 vs. 2009-2018). RESULTS: The filter insertion rate doubled (60 vs. 127 cases) over 2009-2018. In this later period there was an unexpected rise (15 vs. 68 cases, P<0.001) of patients with isolated pulmonary embolism as baseline venous thromboembolism episode, without other relevant changes in patients' profile or survival. Regarding indications, there was an increase in filters for bleeding risk (23 vs. 45) and a reduction for venous thromboembolism recurrence (20 vs. 7), but also an unexpected increase of cases for bleeding (15 vs. 72). Among the 116 retrievable filters indicated for a temporary cause, 70 (60.3%) were finally not removed, being persistence of filter indication (n=33, 47.1%) the most common cause. CONCLUSIONS: The number of filters inserted at our institution has raised over the last two decades. This increase was partly unexpected and perhaps related to the availability of retrievable filters. Unfortunately these devices remain frequently non-removed being persistence of the indication the most frequent cause.

Tratamiento de las trombosis de prótesis arteriovenosas para hemodiálisis asociadas a estenosis anastomóticas venosas mediante trombectomía quirúrgica, stenting cubierto y angioplastia a alta presión / Treatment of arteriovenous haemodialysis graft thrombosis associated to venous anastomotic stenosis by surgical thrombectomy, covered stenting and high-pressure angioplasty

INTRODUCCIÓN/OBJETIVO: La guía de la National Kidney Foundation-Kidney Disease Outcomes Quality Initiative (NKF-K/KDOQI) recomienda que la repermeabilización de prótesis arteriovenosas (AV) para hemodiálisis trombosadas debe alcanzar resultados favorables en el 40 % a 3 meses si es por técnica endovascular, o en el 50 % a 6 meses y el 40 % al año si es por un procedimiento quirúrgico. Este estudio evalúa los resultados de un tratamiento híbrido (endovascular y quirúrgico mínimamente invasivo) de las trombosis de prótesis AV asociadas a estenosis anastomóticas venosas. PACIENTES Y MÉTODOS: Entre 2008 y 2012 se intervinieron 27 pacientes consecutivos (edad media: 69,7 años; 52 % varones) con trombosis de prótesis AV (74,1 % extremidad superior) asociadas a estenosis anastomótica venosa mediante trombectomía abierta (miniincisión en trayecto), stent cubierto autoexpandible (Fluency(R), Bard) y angioplastia a alta presión (> 20 atm). RESULTADOS: La permeabilidad inmediata con hemodiálisis eficaz fue del 89 %, con una estancia media de 1,9 días y ausencia de complicaciones posoperatorias. La permeabilidad primaria a 3, 6 y 12 meses fue, respectivamente, del 51,9 %, 44,4 % y 16,2 % (seguimiento medio: 15 meses). La permeabilidad secundaria tras un nuevo episodio trombótico y procedimiento de similares características (62,9 % de los casos) fue del 70,4 %, 51,9 % y 37 %, respectivamente. CONCLUSIONES: A pesar de ser seguro y poco invasivo, este tratamiento híbrido de las trombosis de prótesis AV asociadas a estenosis anastomóticas venosas solo alcanza resultados competitivos respecto a la cirugía abierta tras un segundo procedimiento iterativo. Debido a esto y a su coste, esta técnica debería reservarse para estenosis a las que sea difícil acceder quirúrgicamente

INTRODUCTION/OBJECTIVE: The NKF-K/DOQI guidelines recommend that the repermeabilisation of thrombosed arteriovenous (AV) grafts for haemodialysis must achieve positive results in 40% at 3 months, if it is performed by endovascular technique, or 50% at 6 months and 40% at one year if it is performed by surgical procedure. This study assesses the results of a hybrid treatment (minimally invasive surgical and endovascular treatment) of AV graft thrombosis associated to venous anastomotic stenosis. PATIENTS AND METHOD: Between 2008 and 2012, 27 consecutive patients underwent surgery (average age: 69.7, 52% male) due to AV graft thrombosis associated to venous anastomotic stenosis (74.1% upper extremity) by open thrombectomy (mini-incision in the graft), covered self-expanding stent (Fluency(R), Bard), and high pressure angioplasty (> 20 atm). RESULTS: Immediate patency with effective haemodialysis was 89%, with an average stay of 1.9 days and no postoperative complications. Primary patency at 3, 6, and 12 months was 51.9%, 44.4%, and 16.2% respectively (mean follow-up: 15 months). Secondary patency after a new thrombotic episode and similar procedure (62.9% of cases) was 70.4%, 51.9%, and 37% respectively. CONCLUSIONS: Despite being safe and minimally invasive, this hybrid treatment for AV graft thrombosis associated to venous anastomotic stenosis only achieves competitive results compared to open surgery after a second iterative procedure. Because of this and the associated costs, this technique should be reserved for difficult surgical approach stenoses
