PASTA repair

Alan M Hirahara, Wyatt J Andersen
PASTA (partial articular supraspinatus tendon avulsion) lesions of greater than 50% thickness are usually repaired, whereas those of less than 50% thickness receive subacromial decompression and debridement. However, tears of greater than 25% thickness of the tendon result in increased strain of the adjacent, intact tendon fibers. Re-creating the tendon footprint at the greater tuberosity is the goal of a repair. Transtendon repairs have been considered the gold standard in repair but have shown varying outcomes and are technically difficult procedures...

OBJECTIVES: Pledget-assisted suture tricuspid valve annuloplasty (PASTA) is a novel technique using marketed equipment to deliver percutaneous trans-annular sutures to create a double-orifice tricuspid valve. BACKGROUND: Tricuspid regurgitation is a malignant disease with high surgical mortality and no commercially available transcatheter solution in the US. METHODS: Two iterations of PASTA were tested using trans-apical or trans-jugular access in swine...

The simultaneous arthroscopic exposure of the subacromial and intra-articular space of the shoulder is challenging in the presence of only partial-thickness rotator cuff tears. We present our experience and method of entering the joint through the opened rotator cuff interval from an anterosuperior portal between the coracoid process and anterior acromion. With moderate (approximately 30°) abduction and external rotation, the rotator interval opens readily, offering a view with the camera toward the anterior edge of the supraspinatus tendon...

Background Specific findings on magnetic resonance arthrography (MRA) that indicate the need for surgery in patients with partial articular-sided supraspinatus tendon avulsion (PASTA) are not well understood. Purpose To determine which MRA findings are characteristic of patients who undergo surgery for PASTA. Material and Methods From July 2011 to February 2014, MRA findings for patients treated for PASTA were retrospectively reviewed. The patients were divided into two groups: conservative treatment and surgical repair...

We performed a pre-dissection computational fluid analysis of an ascending aortic aneurysm associated with unicuspid aortic valve. The analysis showed an abnormal helical flow pattern inside the aneurysm and an increased wall stress on the right postero-lateral wall of the ascending aorta. These values were largely higher than the theoretical cut-off for aortic wall dissection, their topographic distribution followed the intimal tear site as subsequently diagnosed by computed tomography scan and confirmed during the operation for dissection repair...

UNLABELLED: Rotator cuff pathology can contribute to shoulder pain and may affect the performance of sport activities, work, and activities of daily living. The partial articular supraspinatus tendon avulsion (PASTA) lesion represents a very common type of rotator cuff pathology seen in rehabilitation. When conservative treatment fails, surgery is generally required. Success of recovery depends on several factors, including: repair techniques, healing process related to timing, rehabilitation programs, and patient compliance with home exercises...

BACKGROUND: Partial articular supraspinatus tendon avulsions (PASTA) lesions remain challenging with regard to diagnosis and treatment. DIAGNOSTICS: For the diagnosis of PASTA lesions, arthroscopic evaluation of the supraspinatus tendon is key. Preoperative imaging alone is usually not sufficient to make the treatment decision. OPERATIVE TECHNIQUE: For non-significant partial tears of less than 50 % of the tendon thickness a simple debridement is indicated...

Hemodynamic alterations occur when the elephant trunk (ET) technique is adopted to treat extensive aortic aneurysms. In planning the 2nd stage operation to complete ET repair, surgeons must weigh an adequate recovery time after initial surgery against the risk of postoperative ET-related complications. The purpose of this study was to understand the mechanistic link between the flow alteration caused by the ET graft and the development of premature aortic rupture before the 2nd stage operation. Specifically, fluid-structure interaction (FSI) analysis was performed using the CT imaging data of aorta at different stages of ET repair, and then computational variables were compared to those observed in patients who underwent a prophylactic 2nd stage operation to complete aortic repair...

Endografts placed in the aorta for thoracic endovascular aortic repair (TEVAR) may determine malappositioning to the lesser curvature of the aortic wall, thus resulting in a devastating complication known as endograft collapse. This premature device failure commonly occurs in young individuals after TEVAR for traumatic aortic injuries as a result of applications outside the physical conditions for which the endograft was designed. In this study, an experimentally-calibrated fluid-structure interaction (FSI) model was developed to assess the hemodynamic and stress/strain distributions acting on the excessive protrusion extension (PE) of endografts deployed in four young patients underwent TEVAR...

Recent studies have shown that DNA damage occurs more often in hypertensive patients than non-hypertensive individuals. Here, we analyzed the in vivo effect of pasta containing 30% of tartary buckwheat sprouts (TBSP) on spontaneously hypertensive rats (SHRs) and normotensive Wistar Kyoto rats (WKY) to elucidate if TBSP could have an anti-genotoxic effect in hypertensive animal models. Both SHRs and WKY rats were divided into two groups and fed for six weeks with 5 g of TBSP and durum wheat flour commercial pasta, respectively...

OBJECTIVE: To evaluate clinical efficacy of arthroscopic transtendinous repair of partial articular-sided PASTA (partial articular supraspinatus tendon avulsion) injury. METHODS: From February 2011 to July 2014, 12 cases of PASTA, aged 29 to 72 years with an average of 52.9 ± 13.3 years, were treated arthoscopically. To repair PASTA, articular-sided rotator cuff tear was explored, injury site was punctured and labeled with PDS absorbable monofilament suture (Ethicon, Somerville, NJ, USA) suture, subacromial bursa was cleaned up with acromioplasty, and integrity of bursa-side rotator cuff was assessed...

Nitric oxide (NO) levels increase considerably after 24h of exposure of skin to ultraviolet B (UVB) radiation, which leads to nitrosative skin injury. In addition, increased NO levels after exposure to UVB radiation are associated with inhibition of cell proliferation. Compared to the UV-control group, UV-genistein at 10 mg/kg (UV-GEN10) group showed tissue protection, decreased lipid peroxide and nitrotyrosine formation, and low CAT activity. Furthermore, NO levels and iNOS labeling remained high. In this group, the reduction in lipid peroxides and nitrotyrosine was accompanied by upregulation of cell proliferation factors (Ki67 and PCNA), which indicated that prevention of nitrosative skin injury promoted cell proliferation and DNA repair...

There is no current consensus in the literature on the optimal technique for surgical treatment of partial articular-sided supraspinatus tendon avulsion (PASTA) lesions, although most techniques described to date require takedown of the partially torn tendon or passage of an anchor through the already damaged tendon. We describe a novel inside-out repair technique for partial articular surface supraspinatus tears that does not require further disruption of the partially torn tendon by passage of an anchor.

Surgical and conservative management of partial tears of the rotator cuff has long been a controversial topic for many generations of shoulder surgeons. These tears frequently occur on both the articular and bursal surfaces and within the intrasubstance of the rotator cuff. The term "PASTA lesion" describes the partial articular supraspinatus tendon avulsion-type injury. A less common variant of this injury is the bony PASTA lesion or partial articular bony avulsion of the supraspinatus tendon (PABAST).

Over the past years, products of non-animal origin have been increasingly linked to foodborne diseases caused by the enterohemorrhagic pathogen Escherichia coli O157:H7. Contaminated fresh produce and derived ready-to-eat meals are of major concern, since no further or only minimal processing is applied. In this study, flow cytometry was evaluated as a rapid technique to detect E. coli O157:H7 by immunofluorescence, using polyclonal antibodies conjugated to R-phycoerythrin, in refrigerated ready-to-eat pasta salad containing acetic acid and benzoic acid...
