Complications and Solutions in Propeller Flap Surgery
2020
AbstractPropeller perforator flaps (PPFs) have long been proven as valid reconstructive tools for a wide range of soft tissue defects in different body regions. During the last decade, despite their numerous advantages, many authors have thoroughly analyzed outcomes of these flaps, sometimes discouraging their use mainly because of a high failure rate. Accurate patient selection, adequate preoperative planning, and an appropriate dissection technique seem to potentially improve outcomes. Our study provides a review of the relevant literature related to PPF complications and of our experience, describing reasons for failure, measures for preventing them, and approaches for a prompt evaluatio…
Male breast cancer: Reconstructive surgery
2020
The conventional treatment for male breast cancer consists of modified radical mastectomy with axillary sentinel node biopsy and/or axillary lymph node dissection in case of lymph node-positive disease. However, breast-conserving surgery (BCS) is gaining popularity also among men. In both cases, surgery leaves an aesthetic disfigurement that impacts patient well-being and quality of life. Thus, even if male breast has a different social and emotional role than female’s one, male breast reconstruction deserves the same importance. The aim of this chapter is to give a comprehensive review on latest indications and strategies for the post-oncological reconstructive surgery of the male breast.
Simultaneous endovascular treatment of synchronous symptomatic acute type B aortic dissection and large infrarenal aortic aneurysm. Technical tips an…
2020
Highlights • Acute type B aortic dissection associated with AAA, has a high rupture risk. • This complicated dissection must be considered for treatment as quickly. • This approach can be performed endovascularly when supraaortic trunks are involved. • Totally endovascular solution to address both disease is feasible.
Sentinel Node Identification in Melanoma: Current Clinical Impact, New Emerging SPECT Radiotracers and Technological Advancements. An Update of the L…
2020
Background: Melanoma is the most lethal skin cancer with a mortality rate of 262 cases per 100.000 cases. The sentinel lymph node (SLN) is the first lymph node draining the tumor. SLN biopsy is a widely accepted procedure in the clinical setting since it provides important prognostic information, which helps patient management, and avoids the side effects of complete lymph node dissection. The rationale of identifying and removing the SLN relies on the low probability of subsequent metastatic nodes in case of a negative histological exam performed in the SLN. Discussion: Recently, new analytical approaches, based on the evaluation of scintigraphic images are also exploring the possibility …
A low threshold to ECG-gated repeat CTA reduces the risk of false-positive diagnosis of type A dissection in interhospital referrals: a case series s…

Angela Kornberger,1 Iris Burck,2 Hazem El Beyrouti,1 Nancy Halloum,1 Andres Beiras-Fernandez,1 Christian-Friedrich Vahl1 1Department of Cardiothoracic and Vascular Surgery, University Hospital of Johannes Gutenberg University, Mainz, Germany; 2Department of Diagnostic and Interventional Radiology, University Hospital of Johann Wolfgang Goethe University, Frankfurt am Main, Germany Background: False-positive diagnosis of acute Stanford type A aortic dissection (AAD) on computed tomography angiography (CTA) is still an issue and may lead to substantial consequences. Given that electrocardiography (ECG)-gated CTA provides greater diagnostic safety, it may be assumed that interhospital referral…
New applicator improves waterjet dissection quality
2010
Waterjet dissection is accomplished with Helix Hydro-Jet, but a new device with improved operative handling and potentially superior dissection qualities has been developed.Eighty-four fresh cadaveric pig brains were simultaneously cut with Helix Hydro-Jet and Erbejet 2. A commonly used applicator and a new applicator for the Helix Hydro-Jet were directly compared to the new Erbejet 2. Under standardised conditions, different pressure levels were applied to the brain surface without arachnoids. Technical features, cutting depth, tissue damage and differences of applicators were examined.Microscopic analysis of cutting depth revealed different dissection characteristics of both the devices. …
Acute aortic dissection
2011
An acute aortic syndrome with simultaneous presence of a penetrating aortic ulcer, an intramural haematoma, a thoracic aortic dissection and an abdominal aortic aneurysm rupture has not previously been reported. Herein, we describe our experience with a patient treated by endovascular means with an 8-year follow-up.

Inferior mesenteric vein as initial landmark for laparoscopic medial to lateral dissection of descending colon - a video vignette
2017
The root of the inferior mesenteric artery is an important area where autonomic nerves are close by, the dissection can be hard and laborious in order to avoid nerve damage; and the separation of mesocolon and retroperitoneum in this area can sometimes be difficult. The inferior mesenteric vein dissection is an alternative option as the first step during medial to lateral approach of laparoscopic left mesocolon mobilisation, as we have shown in this video based on two real cases and two anatomical cadaveric dissection.

Die laterale Dissektion des Mesorektums ; ein Risiko für den Plexus hypogastricus inferior
2004
Lateral mesorectal dissection may injure parasympathetic and sympathetic pelvic nerves and a partial or complete lesion of the autonomic pelvic nerves leads to urogenital dysfunctions affecting patient’s quality of life after rectum resection for rectal carcinoma. The aim of the present prospective study was to clarify the significance for nerve damage during lateral dissection based on standardized assessment parameters. 15 Patients underwent total mesorectal excision for rectal carcinoma (UICC I/II/III/IV: 1/5/3/6). Within the scope of the stanardized intraoperative data collection it was demonstrated, whether a complete preservation of the autonomie pelvic nerves was successful. In 11 pa…
