Abstract

Due to the limited number of suitable intravital microscopy techniques, relatively little is known about the opto-thermal (endo)vascular responses to selective photothermolysis, used as a default treatment modality for superficial vascular anomalies such as port wine stains, telangiectasias, and hemangiomas. In this preliminary study we present a novel microscopy technique for studying (endo)vascular laser-tissue interactions in vivo, in which conventional orthogonal polarized spectral (OPS) imaging is combined with darkfield (DF) illumination. DFOPS imaging of rat mesenteric vasculature irradiated at increasing powers revealed the following (tissular) responses: formation of translucent aggregates, retrograde flow, gradual and immediate hemostasis, reinstatement of flow, vessel disappearance, and perivascular collagen damage. DFOPS imaging therefore constitutes a useful tool for examining (endo)vascular events following selective photothermolysis.

Fig. 1.

Diagram of the experimental setup. The Cytoscan probe (insert top left) is positioned onto an exteriorized rat large intestine. Source light incident on tissue is passed through a polarizer and a green spectral filter (548 nm). Remitted light is guided through an orthogonally oriented polarizer (analyzer) to a CCD camera by a beam splitter, and the images are video-recorded. A frequency-doubled Nd:YAG laser (532 nm) is used to inflict photothermal damage during DFOPS imaging.

OPS imaging of superficially located microcirculation in the large intestine of a rat. (a) (2.2 MB) Movie: Hierarchical organization of mesenteric vasculature (14.6 MB version). Arrows indicate direction of flow, arrowheads indicate vessel segment with clearly visible leukocyte rolling. (b) (1.4 MB) Movie: Leukocyte rolling and red blood cell-devoid strips of plasma (14.5 MB version). Arrows indicate translucent strips of plasma, arrowheads point to sites of clearly visible leukocyte rolling. Scale bar=100 µm. The original movies in DV.avi format can be downloaded from http://www.opsimaging.net.

Fig. 3.

(a) (1.5 MB) Movie: Formation of translucent matter in laser-irradiated microcirculation (14.0 MB version). The laser was set to a power of 1000 mW, 500 ms pulse duration, and a spot size of 0.35±0.05 mm2. Laser irradiation (white screen in movie) induced the formation of translucent matter (encircled) in the vasculature imaged in Fig 2(a). All yellow crosses designate hemostatic vessels after lasing, white arrows indicate direction of flow before irradiation, and green arrows signify retrograde flow after irradiation. (b) (2.5 MB) Movie: Vasculature in (a), two minutes after laser irradiation (9.3 MB version). The open arrowhead marks the encircled area in (a), the green arrow indicates main flow path of blood, all yellow crosses signify hemostatic vessels, black arrowheads designate translucent, endoluminal obstructions, red arrowhead designates detaching translucent matter, and the red circles demarcate translucent vessel segments. (c) Encircled area in (a) enlarged. Arrowheads point to translucent material attached to the vessel wall. (d) (2.4 MB) Movie: Fig. 3(a), inverted contrast (14.4 MB version). (e) (2.3 MB) Movie: Fig. 3(b), inverted contrast (14.6 MB version). Scale bar=100 µm. The original movies in DV.avi format can be downloaded from http://www.opsimaging.net.

(1.3 MB) Movie: Vessel disappearance following laser irradiation (14.2 MB version). The laser was set to a power of 1500 mW and 500 ms pulse duration with a spot size of 0.35±0.05 mm2. (a) shows a video frame right before laser irradiation (white screen in movie), and (b) displays a video frame immediately after the laser pulse. Small arrowheads in (a) indicate affected vessels in (b), large arrowheads in (b) designate unaffected vessel, and circle marks intact loop vessel. Scale bar=100 µm. The original movie in DV.avi format can be downloaded from http://www.opsimaging.net.

(1.5 MB) Movie: Acute hemorrhage in partially affected vessel 2.5 minutes after laser irradiation at 1500 mW, 500 ms pulse duration, and a 0.35±0.05 mm2 spot size (10.0 MB version). Hemorrhage (encircled) occurs from the large vessel depicted in Fig. 4 without exogenous stimuli. Scale bar=100 µm. The original movie in DV.avi format can be downloaded from http://www.opsimaging.net.

Fig. 6.
Fig. 6.

(a) (1.3 MB) Movie: Disappearance of partially affected vessels following a second laser pulse (9.7 MB version). Vessels from Figs. 4 and 5 were irradiated again 3:45 minutes after the first laser pulse. The laser was set to maximum power (2000 mW) at 500 ms pulse duration and a spot size of 0.35±0.05 mm2. (a) shows a video frame right before laser irradiation (white screen in movie), and (b) displays a video frame immediately after the laser pulse. The demarcated higher order damage region (Fig. 6(b), dotted line) corresponds to the center of the beam profile. Vessel marked by small arrowheads in (a) represents the similarly marked vessel in Fig. 4(a). In (b), black arrowhead indicates hemorrhage, red arrowhead designates translucent material, and green arrows signify retrograde flow. (c) (2.4 MB) Movie: Fig. 6(a), inverted contrast (14.6 MB version). (c) shows an inverted contrast video frame right before laser irradiation (black screen in movie), and (d) displays an inverted contrast video frame immediately after the laser pulse. Scale bar=100 µm. The original movies in DV.avi format can be downloaded from http://www.opsimaging.net.
