Papaverine effect on superficial vein in thumb replantation procedure: A case study.

Key Clinical Message: Topical papaverine is an effective vasodilator that can be used for dilating small veins to accept venous couplers for thumb replantation. This technique corrects size mismatches for successful venous anastomosis and minimizes postoperative complications.

Abstract: Thumb replantation is a complex microsurgical procedure used to restore function and appearance after amputation.

Tumoral calcinosis in the extensor indicis proprius tendon: A case report.

Tumoral calcinosis is a rare clinicopathological entity characterized by the presence of calcified deposits in the periarticular soft tissue. Commonly affecting the hips, buttock, shoulders, and elbow, and less commonly in hands, wrists, and feet. We present a novel case of tumoral calcinosis in a 4-year-old female with an atraumatic wrist swelling for 2 months.

The Lumbar Artery Perforator Flap: 3-Dimensional Anatomical Study and Clinical Applications.

Background: The lumbar region is a potential donor site for perforator-based rotational or free flaps or as a recipient site for free flaps to obtain coverage for deficits in the sacral region. Because of the lack of consensus regarding the microvascular anatomy of this potential flap site, a robust investigation of the anatomy of this region is required.

Methods: Three-dimensional reconstructions (n = 6) of the microvasculature of the lumbar region were generated using MIMICS software (Materialise, Belgium) for each of the four paired lumbar vessels.

Anatomical Study of the Princeps Pollicis Artery Perforator Flap.

Background: The volar aspect of the thumb often requires local flaps for reconstruction. This study characterizes perforators of the princeps pollicis artery (PPA) and evaluates the potential of a local propeller-type flap raised using these perforators for reconstruction of these defects.

Methods: Cadavers underwent whole-body lead-oxide injection and were then imaged using a 64-slice spiral computed tomographic scanner.

Computed tomographic angiography for localization of the cutaneous perforators of the leg.

Background: Results of vascular anatomical studies of the lower limb in the past have been primarily descriptive in nature and are therefore less useful in directing the design of local perforator-based flaps. The purpose of this study was to document the three-dimensional anatomy of the cutaneous perforators arising from the anterior tibial, posterior tibial, and peroneal arteries and provide a statistically verified method for predicting perforator location for use in the clinical setting.

Methods: Computed tomographic angiography and three-dimensional reconstructions of the lower limb using Mimics software were completed for five lead oxide-injected cadavers.

The use of retrograde limb of internal mammary vein in autologous breast reconstruction with DIEAP flap: anatomical and clinical study.

Background: It has been postulated that the abdominal skin may have either predominantly deep or superficial venous drainage. This may account for complications arising from autologous breast reconstruction using the deep inferior epigastric artery perforator (DIEAP) flap. In this study, we evaluate the use of the retrograde limb of the internal mammary vein (IMV) as a second recipient vein in reconstructions with the DIEAP flap.
