Background: Several trials support the trans-radial route of percutaneous coronary intervention (PCI) since it reduces access site vascular complications and bleeding. 

Objectives: To examine the effects of trans-radial interventions (TRI) on clinical outcomes in a 'real world' cohort of patients undergoing PCI.

Methods: We analyzed 4873 consecutive patients who underwent PCI at a tertiary center and identified 373 patients who underwent TRI. Patients (radial vs. femoral) were compared using a propensity score analysis to best match between groups. Outcome parameters included total mortality, myocardial infarction (MI), repeat target vessel revascularization (TVR) rates, length of hospitalization and ∆Ht/Hb/creatinine values during hospitalization. These were evaluated at 6 months and 1 to 3 years after PCI.

Results: The rates of major adverse cardiovascular event (MACE) and its constituents were similar in the trans-radial vs. trans-femoral groups at all time intervals: 6.7% vs. 5.5% at 6 months, 10.3% vs. 10% at 1 year, 15.7% vs. 15% at 2 years, 15.7% vs. 16% at 3 years, respectively (P = 0.6). The length of hospitalization was shorter in the TRI group (2.87 days ± 2.04 vs. 3.3 days ± 3.12, P = 0.023). We did not find significant differences between the groups in the mean ∆Ht/Hb/creatinine values during the hospitalization course.

Conclusions: In a 'real-world' setting of PCI, the TRI route of PCI is as safe and efficient as the femoral approach. TRI is associated with shorter duration of hospitalization.

 

Abstract

Background: Iatrogenic ureteral injury may be seen following abdominopelvic surgeries. While ureteral injuries identified during surgery should be immediately and surgically repaired, those that are postoperatively diagnosed may be treated non-surgically by draining the ipsilateral kidney. Data regarding the outcome of this approach are still missing.

Objectives: To evaluate the success rates of non-surgical management of ureteral injuries diagnosed following abdominopelvic surgeries.

Methods: We retrospectively reviewed the files of all patients treated for iatrogenic ureteral injuries diagnosed following abdominopelvic surgeries. Patients' ipsilateral kidney was percutaneously drained following diagnosis of injury by either nephrostomy tube (NT)/nephro-ureteral stent (NUS) or double-J stent (DJS) inserted retrogradely. The tube was left in place until a pyelogram confirmed healing or a conservative approach was abandoned due to failure.

Results: Twenty-nine patients were identified as having ureteral injury following abdominopelvic surgery. Median time from injury to renal drainage was 9 days, interquartile range (IQR) 4–17 days. Seven cases (24%) had surgical repair. Among the other 22 patients, in 2 oncology patients the conservative approach was maintained although renal drainage failed to resolve the injury. In the remaining 20, median drainage length was 60 days (IQR 43.5–85). Calculated overall success rates following renal drainage was 69% (18/29), and with NS approached 78.5%.

Conclusions: Ureteral injuries diagnosed following abdominopelvic surgeries can be treated conservatively. Ipsilateral renal drainage should be the first line of treatment before surgical repair, and NUS may be the preferred drainage to obtain spontaneous ureteral healing. 

Background: The efficacy of subcutaneous immunotherapy for the treatment of allergic rhinitis, allergic conjunctivitis, allergic asthma and stinging insect hypersensitivity has been demonstrated in several studies.

Objectives: To investigate the effectiveness and side effects of immunotherapy in Israel and the relationship between local and systemic side effects.

Methods: This retrospective study was based on patient records and a computerized database for drug dispensing over a 5 year period. Success was rated as partial or complete. Side effects were classified as local or systemic. Systemic side effects were further classified according to severity, as mild (cutaneous), moderate (respiratory symptoms), or severe (cardiovascular).

Results: Of the 135 patients on aero-allergen immunotherapy who reached maintenance, 120 (88.9%) exhibited complete or partial improvement and 15 (11.1%) did not improve. All of the 44 patients on hymenoptera immunotherapy reached effective maintenance doses. The mean percent side effects calculated per treatment (injection) were 2.49 for local and 1.58 for a systemic reaction during the build-up phase, and 1.13 and 1.12 during the maintenance phase, respectively. Rates of systemic reactions were 1.3% for cutaneous, 1.14% for respiratory and 0.97% for cardiovascular reactions during the build-up phase, and 1.11%, 0.53%, and 0.51% during the maintenance phase, respectively. The odds of systemic reactions were significantly higher in patients with local reactions both in the build-up phase (P = 0.03) and in the maintenance phase (P = 0.0003). The number of annual medications dispensed per patient decreased from 31.5 to 26.0 during the first year after reaching maintenance, and to 22.5 in the second year. Pharmaceutical costs were 67% lower 1 year after the start of the maintenance phase, compared to the year before the start of immunotherapy, and 63% lower in the second year (P = NS).

Conclusions: Immunotherapy was effective and safe. Recognizing the benefits and safety of immunotherapy is necessary for physicians and health authorities in order to provide better care for allergic patients.

Objectives: To present our initial experience with MitraClip implantation in 20 high risk patients at Sheba Medical Center.

Methods: Twenty high surgical risk patients with symptomatic significant MR underwent MitraClip implantation. Clinical and echocardiographic parameters were recorded at baseline and at follow-up.

Results: The patients’ mean age was 76 years and 65% were male. Coronary artery disease was present in 85% and 45% had previous bypass surgery. Renal failure was present in 65%, atrial fibrillation in 60%, and 30% had an implantable cardioverter defibrillator/cardiac resynchronization therapy device. Mean left ventricular ejection fraction was 36%. Grade III-IV MR was present in all patients with the vast majority suffering from functional MR secondary to ventricular remodeling. New York Heart Association (NYHA) class was III-IV in 90%. Patients were followed for a mean of 231 days. Acute reduction of MR grade to ≤ 2 was accomplished in 19 of the 20 patients (95%) with a 30 day mortality of 5%. At follow-up MR was reduced to ≤ 2 in 64% of patients, and NYHA class improved in 70% of patients. An additional 2 patients (11%) died during follow-up.

Conclusions: MitraClip implantation is feasible and safe in high risk highly symptomatic patients with significant MR. Acute and mid-term results are comparable to similar high risk patient cohorts in the literature. Continued surveillance and longer follow-up are needed to elucidate which patients are most likely to benefit from the procedure.

Background: Delays in diagnosis and inadequate treatment of acute scaphoid fractures can lead to non-unions, presenting surgeons with unique challenges regarding optimal management.

Objectives: To evaluate the clinical and radiographic outcome of scaphoid non-unions treated with percutaneous screw fixation.

Methods: The study group comprised12 patients with scaphoid non-unions of an average duration of 8.7 months. There were 11 males and 1 female with an average age of 24 years (range 14–47 years). All patients were initially treated with percutaneous screw fixation without bone grafting. A volar percutaneous approach was used in eight patients and a dorsal percutaneous approach in four. Wrist range of motion (ROM) and disabilities of the arm, shoulder, and hand (DASH) questionnaires were used to assess clinical outcomes. Postoperative radiographs were reviewed to assess the fracture union, carpal alignment and screw position.

Results: Eleven of the 12 (92%) fractures united successfully with no additional procedures. These fractures achieved radiographic union at an average of 4 months. One patient with sickle cell anemia required revision fixation, which consisted of repeat percutaneous fixation and bone grafting. In this patient his non-union healed 3 months after the revision procedure. The average DASH score at final follow-up was 6 (range 0–16). Average wrist ROM was extension of 66 degrees (range 50–80) and flexion 71 degrees (range 55–90). None of the patients showed radiographic signs of osteoarthritis, osteonecrosis of the scaphoid, or hardware-related complications.

Conclusions: For scaphoid waist nonunions without collapse, percutaneous fixation without supplementary bone grafting provides satisfactory results with a high union rate, early return of function and minimal complications.
 

Background: The 20%–60% rate of acute anterior myocardial infarction (AAMI) patients with concomitant left ventricular thrombus (LVT) formation dropped to 10–20% when thrombolysis and primary percutaneous coronary intervention (PPCI) were introduced.

Objective: To test our hypothesis that prolonged anticoagulation post-PPCI will lower the LVT incidence even further.

Methods: Included in this study were all 296 inpatients with ST elevation AAMI who were treated with PPCI (from January 2006 to December 2009). Treatment included heparin anticoagulation (48 hours) followed by adjusted doses of low molecular weight heparin (3 more days). All patients underwent cardiac echocardiography on admission and at discharge. LVT and bleeding complications were reviewed and compared.

Results: LVT formation was present on the first echocardiogram in 6/296 patients. Another 8/289 patients displayed LVT only on their second echocardiogram (4.7%, 14/296). LVT patients had significantly lower LV ejection fractions than non-LVT patients at admission (P < 0.003) and at discharge (P < 0.001), and longer time to reperfusion (P = 0.168). All patients were epidemiologically and clinically similar. There were 6 bleeding episodes that required blood transfusion and 11 episodes of minor bleeding.

Conclusions: Five days of continuous anticoagulation therapy post-PPCI in inpatients with AAMI is associated with low LVT occurrence without remarkably increasing bleeding events.
 

Background: The presence of stones in the common bile duct (CBD) may cause complications such as obstructing jaundice or ascending cholangitis, and the stones should be removed.

0bjectives: To report our results with percutaneous elimination of CBD stones from the gallbladder through the papilla.

Methods: During a 4 year period, six patients (five men and one woman, mean age 71.5 years) who had CBD stones and an existing gallbladder drain underwent percutaneous stone push into the duodenum after balloon dilatation of the papilla, with a diameter equal to that of the largest stone. Access into the CBD was from the gallbladder, using an already existing percutaneous gallbladder drain (cholecystostomy tube).

Results: Each patient had one to three CBD stones measuring 7–14 mm. Successful CBD stone elimination into the duodenum was achieved in five of the six patients. The single failure occurred in a patient with choledochal diverticulum, who was operated successfully. There were no major or minor complications during or after the procedures.

Conclusions: Trans-cholecystic CBD stone elimination is a safe and feasible percutaneous technique that utilizes existing tracts, thus obviating the need to create new percutaneous access. This procedure can replace endoscopic or surgical CBD exploration.
