Chest wall reconstruction for deep radiation necrosis: case report and overview of surgical options.

INTRODUCTION: To report a case of radiation necrosis after reirradiation for breast cancer and the difficulties encountered when treating these complex cases. PATIENTS AND METHODS: We present an 86-year-old woman with a history of right-sided intraductal breast cancer treated with a right mastectomy followed by local adjuvant radiotherapy (50 Gray). Twelve years later, she was diagnosed with a local recurrence in the mastectomy scar which was treated with local resection (including resection of rib four) and adjuvant radiotherapy up to 32 Gray. In July 2020 she presents at the Department of Plastic and Reconstructive Surgery with a chronic ulcer on the right-sided hemithorax. RESULTS: A multi-staged, multidisciplinary approach was necessary to secure lasting coverage of the extensive defect. CONCLUSION: Thoracic radiation necrosis should be subject to a multidisciplinary approach (plastic and thoracic surgeons) pre-, per-, and post-operatively. Each case may require a different surgical approach depending on the size and depth of the defect, patients' age, comorbidities, and previous medical treatment.

BRAVISSIMO: 12-month results from a large scale prospective trial.

The BRAVISSIMO study is a prospective, non-randomized, multi-center, multi-national, monitored trial, conducted at 12 hospitals in Belgium and 11 hospitals in Italy. This manuscript reports the findings up to the 12-month follow-up time point for both the TASC A&B cohort and the TASC C&D cohort. The primary endpoint of the study is primary patency at 12 months, defined as a target lesion without a hemodynamically significant stenosis on Duplex ultrasound (>50%, systolic velocity ratio no greater than 2.0) and without target lesion revascularization (TLR) within 12 months. Between July 2009 and September 2010, 190 patients with TASC A or TASC B aortoiliac lesions and 135 patients with TASC C or TASC D aortoiliac lesions were included. The demographic data were comparable for the TASC A/B cohort and the TASC C/D cohort. The number of claudicants was significantly higher in the TASC A/B cohort, The TASC C/D cohort contains more CLI patients. The primary patency rate for the total patient population was 93.1%. The primary patency rates at 12 months for the TASC A, B, C and D lesions were 94.0%, 96.5%, 91.3% and 90.2% respectively. No statistical significant difference was shown when comparing these groups. Our findings confirm that endovascular therapy, and more specifically primary stenting, is the preferred treatment for patients with TASC A, B, C and D aortoiliac lesions. We notice similar endovascular results compared to surgery, however without the invasive character of surgery.

Treatment of symptomatic mobile aortic thrombus.

BACKGROUND: Mobile thoracic or abdominal aortic thrombi are a potential source of embolism to visceral organs or lower limbs. Detection levels of this type of aortic pathology after any embolic event have increased considerably. Nevertheless, therapeutic management of an intraluminal mobile thrombus of the aorta remains controversial. The aim of this study is to describe the treatment modalities for symptomatic mural aortic thrombi based on three cases diagnosed at our institution and to review the literature. METHODS: During the last decade, several patients with peripheral embolisation were diagnosed with an intraluminal mobile aortic thrombus. Three patients who were treated differently were selected and reviewed. In addition a literature search was performed on PubMed and Medline from their inception to the present for all English language articles using the following keywords: blue toe syndrome, peripheral arterial embolisation, mobile thrombus and aorta. The advantages and drawbacks of medical management, open and endovascular treatment are described. RESULTS: Three particular patients with embolisation due to a floating aortic thrombus were reviewed. The first patient underwent a thoracotomy with replacement of the descending thoracic aorta. Another case was treated successfully by implanting an endovascular stent graft in the descending thoracic aorta. The last patient was treated medically because of the involvement of the visceral vessels. When reviewing the literature, no randomised controlled trials were found but several case reports have described both open and endovascular techniques. No long-term follow up of this rare pathology is available. CONCLUSIONS: In the literature there is no consensus how to treat a symptomatic floating aortic thrombus. This report shows that therapeutic strategies are influenced by the localisation of the thrombus, the co-morbidities of the patient and the physician' s preferences. Endovascular treatment in combination with high dose statins has become the preferred treatment method although long-term data are lacking.

Angioplasty or primary stenting for infrapopliteal lesions: results of a prospective randomized trial.

Excellent results with small stents in coronary arteries have led endovascular therapists to their use in infrapopliteal vessels. However, to date no level I evidence exists to recommend primary stenting over infrapopliteal angioplasty alone. The aim of this randomized single-center trial was to compare their 1-year outcome. A total of 38 limbs in 35 patients with critical limb ischemia were randomized to angioplasty (22 pts) or primary stenting (16 pts). Target lesions were infrapopliteal occluded (36) or stenotic (20) lesions ranging from <2 to >15 cm in length. The mean age was 72 years. At 12 months, there was no statistical difference in survival (angioplasty, 69.3%; primary stenting, 74.7%), in limb salvage (angioplasty, 90%; primary stenting, 91.7%), or in primary and secondary patency (angioplasty, 66 and 79.5%; primary stenting, 56 and 64%) between the groups Renal insufficiency was the only significant negative predicting factor for limb salvage in both groups. In conclusion, the 1-year results for both groups were broadly similar. Stenting has its place in infrapopliteal angioplasty if the procedure is jeopardized by a dissection or recoil, but our results do not support primary stenting in all cases.

A 15-year experience with combined vascular reconstruction and free flap transfer for limb-salvage.

OBJECTIVES: To evaluate the results and complications of combined simultaneous arterial re-vascularisation and free flap transfer in patients with critical limb ischaemia and large soft-tissue defects that would otherwise have required major amputation. DESIGN: Retrospective analysis of all combined procedures performed between 1993 and 2007 with regard to complications and outcome. MATERIALS AND METHODS: Seventy-eight procedures were performed in 76 patients with a mean age of 60 years (range: 18-80 years). The majority had diabetes (70.5%). Follow-up was obtained from hospital charts and telephone contacts with patients or GPs. RESULTS: The limb-salvage rate was 93% after 1 year, 80% after 3 years and 71% after 5 years. Perioperative complications occurred in 50% of the patients; six out of 78 (7.7%) arterial reconstructions and 13 out of 78 (16.7%) flaps had to be revised during the early postoperative period. However, most flaps could be saved by a secondary procedure resulting in an early failure (amputation) rate of 6%. In-hospital mortality was 3.8%. End-stage renal disease was the only factor predicting limb loss. In total, 65% of the patients survived and were able to walk on their reconstructed limb at 1-year follow-up. Combined survival and limb-salvage rates were 85%, 66% and 51% after 1, 3 and 5 years. CONCLUSIONS: Combined arterial re-vascularisation and free flap transfer can be performed safely with acceptable morbidity and mortality and should be considered for every mobile patient with large soft-tissue deficit (>10cm(2)) without end-stage renal disease prior to major amputation.

Retrospective analysis of laparoscopic gastric banding technique: short-term and mid-term follow-up.

BACKGROUND: Although adjustable gastric banding shows good results concerning weight loss, several complications such as excessive vomiting, total dysphagia, and slipping of the stomach through the band with pouch dilatation may occur rather frequently. Different types of adjustable bands are available to prevent these short- and mid-term complications. METHODS: In this retrospective study, 120 consecutive laparoscopic adjustable gastric bandings were performed. In group I, 50 patients were treated with adjustable silicone gastric banding (ASGB) by an intragastric balloon calibration technique. Group II (n = 29) received the same band by a surgical technique with tunneling behind the esophagus toward the angle of His. Group III (n = 41) received Swedish adjustable gastric banding (SAGB) by the same technique as in Group II. RESULTS: Weight loss was approximately 15% of the excess weight after 3 months, 30% after 6 months, and 45% after 12 months in all groups. Total dysphagia was significantly more frequent in Groups I and II. The incidence of slipping of the band and pouch dilatation was more frequent in Group II. CONCLUSION: The diameter of the ASGB band is rather small and can cause total dysphagia independently of surgical technique. The SAGB is easy to perform and seems less vulnerable to complications like dysphagia and slipping of the band, probably because of the individual adjustment of the stoma diameter during surgery and good fixation of both band and ventral pouch with separate posterolateral sutures.
